What is Bulletproof Coffee and How do You Make it?
It’s a high-calorie hot/warm coffee beverage that’s meant to replace breakfast and will keep you full and alert for the entire morning. It raises your metabolism and alertness and helps you lose weight while aiding digestion.
Bulletproof coffee is a deliciously foamy and strong drink that is easy to make if you have the right ingredients and equipment.
To make a serving of bulletproof coffee try the following recipe:
If you don’t already have a blender for hot liquids, check out our recommendations below for countertop blenders, handheld blenders, an immersion blender, milk frothers and even protein shaker bottles that will do the trick. We’ll explain how all these options are possible for great bulletproof coffee.
Why Can’t You Put Hot Liquids in a Blender?
Hot liquids, like coffee or soups, create steam that if not allowed to escape can cause enough pressure to blow the blender lid off and cause a scalding mess on you and in your kitchen. Thermal shock of hot liquids suddenly coming in contact with a hot surface can cause glass and hard plastic to crack or warp.
It’s not that you can’t, it’s just that you should know how to blend hot liquids to prevent these problems. First pre-heat the blender jar by filling it almost full with warm water. Empty it out and then fill the jar with the hot ingredients to blend. In order not to create a bulletproof coffee blender explosion, the blender should only be filled a maximum of a third or halfway up and you should remove the center feeder cap from the lid before closing so as to prevent pressure buildup from the steam. A kitchen towel to cover the hole prevents splatters. Start blending at the lowest speed while holding the lid down firmly, or just pulse if you have that option before you blend at a higher speed.
You should also stay away from the upside-down blenders, like Nutribullet, that are designed for a quick and easy blend and go. The hot liquid will leak through the seal and reach the motor, so after a few days it’ll stop working.
Plastic Blender vs Glass Blender
Another problem you’re likely to face while blending hot liquids is possibly causing damage to your blender over the short or long term. Generally, budget and medium-priced plastic jars are not good for hot liquids or fats in the long term because they expand, crack and warp, causing a leak at the bottom with regular use. There is concern that plastic that comes in contact with hot foods may leech chemicals too. However, plastic is a lot lighter and doesn’t crack or break easily when handled roughly, so you can choose high-end plastic jar blenders that are made to withstand hot liquids and the toughest blending jobs.
Glass is a much better and more durable option if you’re careful while handling it. Of course it is heavy, but won’t get easily scratched and won’t leak after using it regularly for blending bulletproof coffee or hot soups. It also won’t discolor over time or retain food odors.
Some countertop blenders are so powerful and run at such high speeds, that if you run them long enough, they can blend your cold ingredients and then heat them to make hot soup just by the friction from the blades. These are the most durable blenders to use for bulletproof coffee, as they’re actually designed to withstand high temperatures. Make sure that the blending power is rated at least 1200 watts, as anything lower will not do the job. Some lower priced glass jar blenders without the heating feature can also be used, but to ensure that pouring in hot coffee doesn’t cause the glass to crack through thermal shock, pre-warm the jar by filling it with warm water and emptying it out just before adding the hot coffee.
Do You Have to Blend Bulletproof Coffee?
If bulletproof coffee is the only thing you’re going to use a blender for then you don’t need a countertop one. Some people like to use an immersion blender for easier cleanup. However, because of the hot liquid, the pressure created makes the foamy coffee rise up fast and flow over the rim of the beaker it’s blending in. It’s better to use a tall jug or beaker to blend the coffee in and then pour it into your drinking mug.
You also don’t need to use any blender at all and instead get a milk frother. A handheld milk frother is inexpensive and does the job well while being easy to clean. You can make the bulletproof coffee directly in your mug without creating a mess.
Another option is a protein shaker bottle. It’s like a travel mug with a lid and a wire whisk ball inside. You fill the bottle with the coffee, drop the whisk ball in, close and shake the bottle well. The whisk gives you creamy coffee.
If you’re not using a blender, but instead a frother or shaker, then put the butter and oil in first and slowly pour in the hot brewed coffee over that so that no solid bits of butter are left.
Which is the Best Blender for Hot Liquids?
Vitamix 5200 Blender
A Vitamix blender is what you’ll find in established restaurants and cafes across America. That is because it is high powered, cleverly designed, can withstand regular use and does the job extremely well. When you make a smoothie you won’t get seeds in it and there will be no pulpy bits. You will actually be able to drink it easily. When you make a soup from whole ingredients and leave it on for a bit, the sheer friction of the high speed blades heats up the blended soup so that you just have to pour it out into your bowl and eat. You won’t have to chew because there are no bits left.
The Vitamix 5200 Blender is a perfect multipurpose blender for small, medium and large batches to be blended. It comes with a 64 oz blending jar made of Eastman Tritan, a BPA-free virtually indestructible plastic that can with stand crushing ice and blending hot liquids like soup and coffee. Even though it is a big jar, it is very light. The narrow base and tall height of the jar means that even single person servings can be blended because the blades can pull every little bit of the ingredients into a vortex in the center. Why have different sized jars for different size jobs?
Along with the 2 peak HP motor, the hardened stainless steel blades can pulverize anything and emulsify the butter and oil with the coffee in a matter of seconds. If you use cold brewed coffee, there’s no need to pre-heat it before adding it to the jar, as the blender can do the job for you. It has a variable speed control knob that you can use in the middle of the blend, so you can start slow to prevent splattering and then increase it to a higher speed to get a perfectly foamy bulletproof coffee.
The radial cooling fan and thermal protection system ensures that there is no danger of damaging the blender when you use it for hot coffee or other hot liquids or ingredients.
For blending smoothies and soups, there’s a specially designed tamper that you can use to scrape and push down ingredients without turning off the blender.
You can easily clean the inside of the jar by blending just a drop of dishwashing liquid with warm water and let it run for 30-60 seconds.
It comes with a full 7 year warranty, which helps when you consider the high price. Consider this as an investment, especially if you think you’ll need for lots of different blending jobs.
The only negative is that this blender will not fit under standard kitchen wall cabinets, as its total height including the base is 20.5″.
Blendtec Total Classic Countertop Blender
Now we come to the most powerful blender you can buy. With a motor powered at 1560 watts and up to 3 peak horse power, the Blendtec Total Classic Countertop Blender takes that honor. It has become a worthy competitor to Vitamix and you may even find it better for your needs and may be the best blender for keto coffee.
This blender comes with the BPA-free 75oz FourSide jar, so you can make bulletproof coffee or any other hot or cold mixes for up to 4 people, but it will also work well for coffee for one. It will fit under regular height kitchen cabinets, which is a big plus over the Vitamix.
The blades are strong and blunt to pulverize instead of cutting ingredients, you’ll never cut yourself accidentally. The tips are winged upwards to create a vortex that pulls everything to the middle, which enables extremely smooth blends of everything from iced smoothies to high-fibre soups, so there’s no need for a tamper. The friction from these blades will turn a cold blend hot in under 6 minutes.
If you like to manually control your blending you can do so using the “+” and “-” one-touch speed buttons for 10 different speeds. There is also a pulse button. For those who like a set and forget approach, there are 6 pre-programmed cycles for Smoothies, Batters, Hot Soup, Whole Juice, Ice Cream and Ice Crush. An illuminated LCD timer shows remaining time on programmed blends. Using either the manual speed controls or the hot soup program, you’ll get a perfectly smooth and foamy bulletproof coffee without causing an explosion.
This blender will also self-clean if you just add a drop of dishwash liquid and warm water to the jar and blend for 60 seconds.
It comes with an 8 year warranty, not that you’ll need it!
The only thing you may not like about this blender is that it is noisy! If you’d prefer a quieter blender, you could try one that employs noise damping or one that comes with a noise shield. There’s a Blendtec option there too.
Cuisinart CBT-2000 Hurricane Pro Blender
The Cuisinart CBT-2000 3.5 Peak Hurricane Pro Blender is the final high end choice of blenders to consider for bulletproof coffee. Its 64-ounce BPA-free Tritan plastic jar with BlendLogix operating technology that includes variable speed control, Turbo Boost for maximum blending power and automatic load sensing, are professional features that warrant its upper end cost.
This blender crushes through ice in seconds, while the 6-prong stainless steel blade easily handles things like nut butters, hummus and batters. The BlendLogix technology knows to start blending at a low speed and gradually increase to the maximum speed needed. It senses the load you add and adjusts for uninterrupted blending without the need for tampering.
You get 5 preset programs – 2 settings for Smoothies (veggie or fruit), Ice Crush, Soup, and Clean. You also get 4 manual speed setting using the speed dial – Low, High, Pulse and Turbo. If you find that any of the presets need to be tweaked according to your preferred consistency, you can do so and then save that to the preset using the Memory function. It will stay until you change it. An LCD display will show a countdown timer to whichever preset you choose.
While this 3.5 peak HP model gives you the ability to make hot soup in 6 minutes just from the blade friction, the lower powered model 2.25 HP does not, so be careful when looking at reviews. The higher HP model is the one you should use for bulletproof coffee. The tight-seal lid with 4 small vents for team escape comes with a center cap that doubles as a 2-ounce measuring cup.
At 17.5″ tall, this blender may or may not fit under your upper kitchen cabinets, so it’s best if you measure first if you intend to store it under one.
This blender comes with a 3 year overall warranty and a 10 year limited warranty on the motor.
Best Blender with Glass Jar
Ninja Foodi Hot & Cold Blender
You will probably see many bulletproof coffee blender recommendations online for the Ninja Professional blender. While it is a very good blender for smoothies and other cold blending needs, it is NOT designed for hot liquid blending and many complaints about it developing leaks after a few months is because it was regularly used for making hot soups or bulletproof coffee. Instead, take a look at the Ninja Foodi Hot & Cold Blender that’s specifically designed to do both and even costs a lot less than a Vitamix or Blendtec. It saves you time and cleaning because you can do all your heating/cooking and blending with just this one appliance instead of using up a separate pan for the cooking. It’s a great tool to have in your kitchen if you’re into doing several types of meal replacements throughout the week.
For those who have health concerns regarding hot foods coming in contact with plastic, this Ninja blender has a glass pitcher. Its capacity is 64 ozs and the motor rating is 1400 watts with up to 1.9 peak hp.
Like other Ninja blenders, this one has all the abilities to crush and blend iced drinks, smoothies, sauces and dips to a very smooth consistency. However, this blender uses a different method to make hot soup, as the blades don’t work fast enough to create heat from friction. Instead, there is a 800-watt heating element in the base. This element can be used to cook proteins and vegetables before they’re blended to make hot soups. It is also useful for making infused fruit drinks, cocktails and sodas, melting chocolate, toasting spices and more.
There are 12 Auto-iQ programs that use a mix of pulsing, pausing and heating if needed to deliver great results with just a touch of a button. There are also 7 manual functions if you want more control of the blending or cooking process.
This high speed blender with glass jar comes with a cleaning brush, tamper and a pitcher lid with center cap that you remove if you want to blend hot liquids, like bulletproof coffee. The non-stick ceramic coating of the bottom of the glass jar is PTFE and PFOA free and makes cleaning easy. You can’t put the pitcher in the dishwasher because of the heating element, but there is a clean function that you can use. To make the job really easy you should first rinse it out as soon as you’re done blending, then add some water and liquid soap and run the clean program. If there are stubborn stuck bits, the included cleaning brush can reach even under the blades.
You should be aware that this blender is tall and may not fit under your kitchen cabinet. It is 17.9 inches tall with the lid on. It is also quite heavy along with the glass jar but doesn’t have a very large footprint, so it can be stored inside a cabinet.
Instant Ace Plus Blender
From the makers of Instant Pot comes the Instant Ace Plus Blender with a 54 oz glass jar and hot and cold settings for heating and blending. It is similar to the Ninja Foodi because it comes with a concealed heating element at its base and a glass pitcher. You can make everything from hot soups and nut butters to dips and non-dairy milks.
This blender’s pitcher is a bit smaller at 54 oz., and therefore a bit shorter at 17 inches. You can store it under most kitchen cabinets. It operates at 1300W when blending, and 800W when heating.
It has 8 hardened steel blades that pulverize ice, fibrous vegetables and nuts and seeds. The accessories that come with it are a patented 3-in-1 food tamper, a cleaning brush, a measuring cup & and a machine washable strainer bag for making various milks.
A big way in which it differs from the Foodi is when you can heat ingredients. There is no non-stick surface at the bottom to saute veggies here. Instead you first add ingredients and blend before heating the mixture. So you can puree and blend ingredients for sauces and instead of emptying out the mixture, just heat it up in the blender itself before serving. Or you can add veggies or even meat, blend those and then add noodles to cook at the same time that the blended mixture is heating.
There are 8 pre-programmed buttons for smoothies, crushed ice, frozen desserts, various types of milk, purees and soups and you can set one to start up to 10 hours later. If you prefer more control and customizations, there is a 10-speed control as well. Once done, you can use the “Warm” function to keep hot blends warm for up to two hours. You can do this for your bulletproof coffee as well once it’s perfectly blended if you want to keep it hot until you’re ready to drink. The LCD display will show you real time temperature of the mixture in the blender.
This blender comes with a 1 year limited warranty.
Best Small Blender for Bulletproof Coffee
Oster Versa Blender – 1400 Watts
The 1400 Watts Oster Versa Blender can hold up to 8 cups. The height of this blender is 17.5 inches with the lid so it is probably one of the best small blender for bulletproof coffee and will fit nicely under your kitchen cabinet.
In addition to being able to manually control the speed, this blender comes with three settings that are pre-programmed so that you don’t need to stay with the blender when you select any of them. These settings are for smoothies, soups, and dips/spreads. You can use the manual pulse or programmed pulse setting to crush ice.
This blender will heat your ingredients through blade friction, so you can add hot ingredients to the jar. The base is extremely sturdy and won’t jump around when you start blending hot liquids or hard ingredients.
The stainless steel blade spins at over 250 mph to give you a perfect consistency for soups, nut butters, salsas and more. A tamper is included for more stubborn ingredients.
It comes with a 7 year limited warranty.
Bulletproof Coffee Blender Bottle
Do I have to use a blender for bulletproof coffee? The short answer is not really. As long as you agitate all the hot ingredients enough for them to mix well and emulsify, an actual blender is not necessary. However, a blender will do the best job of creating a smooth and foamy drink in a very short time, so if you don’t already have one and think you can use one for more than just making bulletproof coffee, then any one of the above blenders is a good investment.
If you only want to make your keto coffee then you can save money by just buying a good protein shaker bottle that can handle hot mixes being shaken vigorously. They come with a wire ball that’s dropped into the bottle along with the ingredients. You close the lid and shake the bottle hard for a few seconds to mix everything thoroughly.
But can you put hot liquid in a blender bottle? Most protein shakers are made of plastic or don’t have an airtight seal, so hot coffee along with fat will build pressure and make the contents leak and splatter and the plastic body won’t look as new over a period of time. That’s why it’s recommended that you get a stainless steel insulated one with a tightly sealed cap. If it’s filled just 1/2 or 1/3 of the way the contents will remain safely inside but well blended.
Hydro Flair Stainless Steel Protein Shaker Bottle
The 20 oz Hydro Flair Stainless Steel Protein Shaker Bottle is one of the few that can be used to make bulletproof coffee safely.
Its stainless steel double-walled vacuum keeps cold beverages cold for more than 24 hours, while hot beverages will stay hot for up to 8 hours. It comes with a leak-free screw on cap, as opposed to the standard fliptop cap because it can withstand built up pressure inside and won’t pop off and spew the contents of the bottle. It’s also safer when opening the bottle after shaking the hot contents because pressure and steam is released slowly as you unscrew the cap.
It comes with two shaker balls – a metal one for hot drinks and a food-safe plastic one for cold drinks. The metal one can actually be used for both types.
This bulletproof coffee shaker bottle is easy to clean and dishwasher-safe. It fits standard car cup holders, so you can make your coffee in it and take it with you to work or the gym and you’ll still be able to drink it hot.
Best Hand Blender for Bulletproof Coffee
If you don’t have space in your kitchen for a new countertop blender or you want to make cleanup easier, then an immersion blender will do the job. You hold it by the arm and insert the head into the mixture that you want to blend. You should get one that has a very slow speed setting so that you when you start mixing the hot fat and coffee, it won’t splatter all over your kitchen. After the initial mixing you can increase the speed to create a fully emulsified coffee. It should also be tall and narrow with enough capacity to hold a foaming drink, otherwise the mixture will overflow easily.
There are many good immersion blenders that will make everything from baby food to smoothies, including big brand ones, but here are two options that are the most versatile handheld blenders you can buy.
Mueller Austria Ultra-Stick 500 Watt 9-Speed Immersion Multi-Purpose Hand Blender With Whisk, Milk Frother Attachments
The Mueller Austria Ultra-Stick 500 Watt 9-Speed Immersion Multi-Purpose Hand Blender is powerful enough to give you a very smooth blend of keto coffee and also has 8 variable speeds along with a turbo function to tackle different jobs. You can start blending hot coffee slowly and gradually increase the speed without causing splatters.
The blender has a removable blending shaft with a stainless steel S-shaped fixed blade that locks into the all-copper drive motor part of the body. As a bonus, you also have two other attachments – a whisk and a milk frother, the latter of which can also be used to make a slightly less blended bulletproof coffee. They’re all easily interchangeable. The blender blade easily and quickly blends ingredients for smoothies, milk shakes, sauces, soups or baby food, and can also blend butter, oil and hot coffee to make a creamy and frothy drink. The comfortable ergonomic grip is non-slip and easy to use when continuously blending ingredients.
It doesn’t come with a mixing jar so you’ll need your own that’s tall enough. The removable blender shaft, whisk and frother are all dishwasher-safe.
This blender is Austrian made and comes with a 100% 2 year warranty.
KOIOS Oxasmart Immersion Hand Blender
For a few dollars more you could consider getting the KOIOS Oxasmart Immersion Hand Blender. At 800 watts with an all-copper motor drive, it is the most powerful handheld blender available and comes with 12 speeds plus a turbo button for the final smoothest blend.
The stainless steel titanium-reinforced blades are not only able to cut through the toughest vegetable and fruit fibres but will last for years and resist corrosion. The bell-shaped cover around the blades minimizes splashes while blending and the 8″ blending shaft enables you to reach to the very bottom of a soup pot.
This 4-in-1 set also includes a BPA-free 500 ml/17 ounce food chopper, an egg beater/whisk, and a 600 ml/20 ounce beaker.
