This Bulletproof Coffee is a creamy and smooth keto coffee. It’s a zero-carb breakfast made of healthy fatty acids from MCT oil and butter. Bonus, all you need to make this keto coffee recipe are 4 simple ingredients!
Coffee lovers, I have great news for you: coffee is keto-friendly. That’s why I’ve made so many keto coffee recipes over the years, like my Keto Iced Coffee, Keto Pumpkin Spice Latte, or Keto Bulletproof Latte. Even better, you can make some delicious and easy keto coffee recipes that taste like your local coffee, at home in 5 minutes.
Bulletproof coffee is a popular keto breakfast drink created by Dave Asprey. It replaces your traditional cup of coffee or coffee latte. It is smooth and creamy as a latte coffee but does not contain any milk, sugar, or carbs. Instead, it contains all the fatty acids you need to produce ketones quickly and keep your energy levels steady.
Ingredients and Substitutions
- Hot Brewed Coffee – Since you must blend your ingredients together, it is very important to start with hot freshly brewed coffee. Instant coffee would work as well, but the flavor of your keto coffee won’t be as good.
- MCT Oil – MCT Oil increases the sensation of fullness, improves gut health, and on a keto diet, it also promotes fat burning as it gives a quick supply of ketones to your body. You can swap MCT oil for extra-virgin coconut oil, but MCT oil is far more concentrated. In fact, MCT oil contains is entirely made of Medium-Chain Triglyceride compared to about 50%-60% in coconut oil. The main fatty acids from MCT oil are Caproic acid (C6), Caprylic acid (C8), Lauric acid (C12): a powerful anti-fungal and antibacterial that shows benefits to your gut health and helps people on a candida diet.
- Unsalted Butter – Grass-fed butter is added to keto bulletproof coffee for texture and creaminess. Butter (and Ghee) are very much keto-friendly because they contain barely any fat. While it also adds healthy fat to feel fuel and keep your energy level steady, it adds a smooth texture that MCT doesn’t have. A rich, creamy texture to your keto coffee recipe while adding fulfilling fat.
How To Make Bulletproof Coffee
Bulletproof coffee is very easy to make, in particular, if you have a good Espresso machine. It only takes 3 ingredients!
- A keto bulletproof coffee recipe is very easy to make with only 4 ingredients. However, the key to making a tasty keto coffee with butter is to use a blender! In fact, you must blend all your bulletproof coffee ingredients on the high-speed setting or the creamy coffee texture won’t form. If you don’t blend your brewed coffee with MCT oil and butter, it will result in two layers, coffee at the bottom and fat on top. It won’t taste good at all! Another option is to use an immersion blender or hand milk frother.
- Place all the ingredients in a tall mug, wide enough to fit your immersion blender or milk frother. Blend until creamy.
Frequently Asked Questions
It’s the most common question on a keto diet. Technically, yes any calorie can break a fast. However, on a keto diet, fat is your fuel.
So if you only consume pure fat, no protein, no carbs during your fast, you won’t break it.
It means that drinking bulletproof coffee won’t hurt your fast at all. You will simply add more energy to your body and fullness that help you last your fast longer! So yes, you can drink one bulletproof coffee while fasting.
This will boost your fat-burning metabolism and help you fast longer without feeling hungry too quickly.
Since fat slows down your digestion, adding fat to your coffee creates a feeling of fullness and keeps your blood sugar level steady for longer.
It means that the benefits of adding fat or butter to coffee are great for anyone, not only people on a keto diet.
However, keep in mind that bulletproof coffees are high in saturated fat, and not suitable for people with cholesterol or some other health issues.
Also, if your body is not fat-adapted, meaning it is not used to using ketones as a source of energy, it won’t have the weight-loss benefits it brings to someone following a keto diet.
The potential weight-loss effects of keto butter coffee are for people following a strict weight-loss keto meal plan.
Some of the bulletproof coffee benefits you may experience after drinking bulletproof coffee on a keto diet are:
– No energy crash, steady energy level
– Fullness and less hunger
– Increased mind focus
– Weight-loss
– Fighting the keto flu
You can make your keto coffee even tastier by adding some of the following:
– Collagen peptides – add 1 tsp of collagen powder, some are vanilla-flavored and will give a tasty vanilla flavor to your keto coffee.
– Heavy cream – if you are not drinking this bulletproof coffee during your fasting period, feel free to add 1 tablespoon of heavy cream or unsweetened almond milk.
– Sugar-free sweetener – make it sweet by adding safe keto sweeteners like 1-2 teaspoons of stevia drops or 1-2 tablespoons of erythritol.
– A pinch of ground cinnamon on top – it doesn’t add carbs to your drink but a lovely cinnamon flavor
You can also try adding my keto pumpkin creamer or keto condensed milk to your bulletproof for extra flavors!
On a keto diet, your body is in a shortage of carbohydrates and cannot produce use glucose as a source of energy.
Instead, your body uses ketones, which can be consumed by your muscles or brain as an alternative source. So feeding your body with fatty acids that can quickly generate ketones is the key to:
– Keeping your energy levels steady,
– Feeling fulfilled and not hungry.
– Increasing your focus and mind clarity.
– Boosting your weight loss.
Bulletproof coffee is a coffee full of quality fat, like MCT oil and butter. MCT oil or Medium Chain Triglyceride is made of 3 fatty acids that have medium-length chains.
It means they are broken down fast, and they are quickly absorbed by your body to produce ketones, your source of energy in ketosis.
MCT oil in keto coffee goes straight into your liver to produce ketones.
Bulletproof coffee helps you lose weight faster on a keto diet because it provides a quick and steady source of fat to give your body energy and fullness.

Omg this is delicious my first bulletproof keto coffee thank you😋
I noticed this recipe is for 8oz. of coffee. I drink more than that each morning. Can I increase the amount of coffee, butter and oil to match the 16oz I normally drink? Or is this amount of butter and MCT oil the daily recommended amount?
Thanks!
On a keto diet you should track your fat intake but also your calorie intake. As soon as the amount of MCT oil or butter you eat match your macro and weight goals, then you are fine.
DO you drink this during the fasting period or at the end? Example If I’m doing 7-11AM I would have this at 11Am to break my fast?
Not really, fasting should focus on zero calories drinks. Read more about the keto fasting rules on my article here.
Can I put Splenda Keto liquid into this?
Sure
I don’t drink coffee at all. Is there something else that I can use instead. I drink tea
Try my bulletproof tea recipe!
I use a T of heavy or full fat cream and a T of C8 only MCT oil so I don’t have to blend it with my noisy blender. Mixing works geat. I also add some Ceylon cinnamon, some medicinal mushroom powder and possibly a little suar free cacao.
Hi Carine! I have to use extra Virgin coconut oil or can I use refined coconut oil instead?
Both works the same but refined coconut oil has no coconut flavor
Thank you for this recipe. Does it have to be caffeinated coffee?
No you can use decaf! Enjoy
First, I want to thank you for so many fabulous recipes! Just curious…why does MCT oil and grass-fed butter not break your fast but heavy cream will?
Thanks for following my recipes ! Well, heavy cream contains carbs 3.7 g per 100 ml but MCT oil, coconut oil or butter contains zero carbs its pure fat, so it doesn’t impact your blood sugar level or ketosis. I hope it make sense, Enjoy the coffee! XOXO Carine
I’ve made this the past 2 mornings and haven’t missed the cream like I thought I would. Thanks for your reply…really appreciate the insight! 🌞
Hello! I am so happy you love it too 🙂 Thanks for the lovely feedback, Take care, XOXO Carine
I have come across FB group pages on Keto saying that putting hot coffee in a blender might lead to an accident where the blender explodes due to the hot liquids being put in the machine. But I see that you just put the hot coffee in your blender as seen on the video. Have you encountered/heard other stories like these before? It makes me scared to try blending my BPC since I have an Oster Glass blender and not like yours which I am guessing is more expensive. Thanks for the tips.
If you keep the little “cap” to the blender lid off and place a kitchen towel with your hand lightly holding the towel in place over the exposed hole in the lid, you can blend away and you won’t have a mess in your kitchen. Works great every time!
Not all blender can handle warm liquid, but most of them can, especially if yours has a glass jug ! Glass resist really well to high temperature. Simply refer to the manufacturer manual to be sure your brand can blend hot liquid. Mine is a Kitchenaid and can handle soup and any liquid between 190F and 210F so it can easily blend a freshly brewed coffee. Another option as mentioned in the post is to place all the ingredients into a coffee mug or large tall recipient and use an immersion blender or milk frother. Enjoy, XOXO Carine
