Bulletproof Coffee (Unicorn Fuel)

In this post, I am sharing a bulletproof coffee recipe with coconut oil and butter or ghee and discussing why it’s often referred to as “unicorn fuel.” Plus, is it worth the hype?

You’ve probably heard of bulletproof coffee or butter coffee by now – it’s the trend that’s taken coffee to a whole new level. If you haven’t come across it yet, it’s made by blending black coffee with unsalted butter and coconut oil or MCT oil.

It is claimed to have multiple benefits, from improving mental focus and physical performance to increasing energy and speeding up fat loss. Bulletproof coffee is becoming increasingly popular and I’ve even noticed it popping up on the menu in many cafes.


The Origins Of Bulletproof Coffee

Dave Asprey, Silicon Valley investor, technology entrepreneur and self-proclaimed ‘biohacker’, is the founder of The Bulletproof Executive. He first came across the idea of adding butter to a hot drink when he tried butter tea while hiking at -10 degrees in Tibet. This traditional drink is made from strong tea churned with yak butter and salt.

Now, I have to say that I tried butter tea when I was hiking in Nepal, and I was not inspired to try it ever again. But, Asprey was ‘rejuvenated’ by the beverage and when he returned to the States began researching the benefits.

The official bulletproof coffee recipe includes black coffee, unsalted grass-fed butter and MCT oil (medium-chain-triglyceride oil, which is an extract of coconut oil and is said to be 6 times more powerful than coconut oil). When blended in a high-speed blender the butter emulsifies, creating a creamy, frothy drink.

Benefits Of Bulletproof Coffee

For many people coffee can have negative side effects – after the initial buzz there comes a crash, followed by the jitters, anxiety, an upset stomach and disrupted sleep. According to Asprey, these negative side effects are caused by mycotoxins – harmful compounds created by moulds growing on the coffee beans. To avoid this, it’s important to use a good quality coffee (and if you want to go all out you can buy the official bulletproof ‘upgraded’ beans).

Additionally, the type of saturated fat in butter and coconut oil slows down the caffeine rush providing a more sustained release of caffeine.

The benefits of bulletproof coffee are said to be:

  • Improved cognitive function (focus and memory)
  • Improved physical performance
  • Increased energy
  • Suppressed food cravings (as the fats will keep you satiated)
  • Fat loss

Next-level Bulletproof Coffee

If you still can’t get your head around adding butter and coconut oil to coffee, wait until you hear some of the ways people are pimping their butter coffee.

There are recipes out there with added vanilla, maca, cacao, gelatin, protein powder, and spices such as cinnamon and turmeric.

The Paleo Chef’s ‘Unicorn Fuel’ has become a hit, people are adding pumpkin puree and spices, and even bulletproofing their morning smoothies.

If you’re not a coffee drinker, you can use tea instead. Try bulletproof chai tea or bulletproof green tea with matcha.

My Verdict On Bulletproof Coffee

I’ve tried butter coffee a few times, and sometimes just add a teaspoon of coconut oil to my black filter coffee. I find it does give a more gentle, even caffeine release without the usual coffee jitters. It is also really satiating, and you might find you are not hungry for several hours after having a cup.

Many people take bulletproof coffee instead of their breakfast or to replace one of their meals, and although I think that it’s a handy alternative fuel source that can be used for convenience during a busy day or during intermittent fasting, I don’t think it should replace a regular high-protein, satiating breakfast as you’d be missing out on an array of essential nutrients found in real, whole foods.

Do you drink bulletproof coffee or have you ever tried it? What do you think – did you notice any of the benefits? What do you add to pimp your butter coffee? Let me know in the comments below. In the meantime, here is a recipe for homemade bulletproof coffee with coconut oil and butter or ghee (depending on whether you want a paleo/Whole30 or primal/keto version).

  1. I’ve just started taking a homemade bulletproof coffee with coconut oil and organic (mostly pasture fed) butter – recently diagnosed with SIBO and no dairy (except butter) for me! I like it – and am keen to try some different variation.

  2. 4 stars
    I have been using it for about a month, maybe twice a week at most. As someone that is used to drinking long blacks or Americanos it is quite a contrast. It definitely is satiating, and I have managed to go from breakfast to lunch on one big cup. I must admit that adding coconut oil that is free from a strong taste/aroma helps, I also add a teaspoon of maple syrup although I am hopeful that this doesn’t cause too much of an insulin response!

  3. MCT oil is much much better than coconut oil IMO. I have a BP coffee instead of breakfast a few times per week and it really keeps me energized and full the whole morning. I often add cinnamon and/or vanilla and/or collagen hydrolysate.

  4. I got turned onto bulletproof coffee about 3 weeks ago..

    I usually have one after my morning run and it keeps me going both mentally and nutritionally (i.e I don’t feel hungry until mid afternoon)

    I use the best quality coffee I can find locally, MCT oil and Kerrygold unsalted organic butter

    At the beginning of October I weighed 110 KG now on November 7th I have just hit 102KG, I Put this down to 3 things.

    Walking/running 10kg each morning
    Drinking Bulletproof coffee
    Not drinking alcohol

    Inow fitter healthier and waaaayyyyyy more boring!

  5. On work days I use a mug and microwave to scramble an egg, with 2 Tbsp of cream whipped in with pepper and salt. It takes about 2 mins. I put a large knob of butter in just before I start to eat it.

    Why would I ruin a good cup of coffee when I can get my fat fix with an egg? They both taste better this way.

    Is bulletproof coffee for people who watch the Late show and cannot afford the 5 mins required to cook and eat a scrambled egg?

    1. Because the coffee tastes great that way 😉 I guess if you like black coffee, it wouldn’t be so appealing though. I’m also anti-microwave so it’d take me longer to cook egg!

    2. You missed the point. Obviously, one can eat eggs separately. This is an alternative that is handy and very tasty- but to each his own!

  6. I love bulletproof coffee! I make mine with espresso rather than filtered coffee, and enjoy it with my breakfast of primal quiche with vegetables, and fruit-coconut cream-nut bowl. It’s one of my faovurite parts about primal eating!

    I agree, it shouldn’t be substituted for a protein-packed breakfast. And people shouldn’t knock it until they try it, not all of us have microwaves.

  7. Try blending an egg with your bullet proof coffee… Tasted really nice, and gives you a bit of protein at the same time. I add a bit of vanilla also.

  8. 5 stars
    I’ve just started having my own version of bulletproof coffee and have it midmorning, so after a good breakfast and really am not hungry till 2 or 3 in the afternoon!

    I find espresso coffee from my machine the best!
    I add some hot water, 1 tbsp. grass*fed butter, 1 tbsp. extra virgin coconut oil and a good dash of cream.
    I whip it together and have a delicious creamy, frothy, sustaining drink!

  9. 5 stars
    I was very sceptical at first but really like it. Wonder if there is a speedy version for preparing it at the office i.e. shaking ?

    1. I think with enough shaking you could probably get it frothy enough. Otherwise, you can get one of those hand-held milk frothers and use it in a large cup with the bulletproof coffee too.

  10. Made this a few times several years ago- still love it. Tried it with stevia, which I usually find to be too bitter, but it was good. My girlfriend enjoyed it too and she doesn’t like stevia. I love how soft my lips feel from this too.

  11. My own recipe for what I call keto coffee is to use 1 Tb of coconut oil, 1Tb of red palm oil and 1tsp of Thai chili flavored olive oil to a 12 mug of bullet proof coffee. Blend well to a nice froth with a stick blender and, viola, a great cup of coffee that has thinned me down and gives me energy from 8AM until 2 to 3 PM. I’ve been using this off and on for about a year now and it still continues to make me feel good. One thing to note if you are just learning to drink this…start slowly. Befin with a teaspoon of the main os and only a 1/4 tsp of the chili flavored olive oil. Work up to the stronger version over several weeks.p

  12. Hi Irena, for the last year I’ve been drinking butter coffee in the morning on average about 3 to 5 times a week and definitely notice a boost of energy as well as being more focused. I always add a tablespoon of brain octane oil in my coffee. Cheers 🙂

    1st time I’ve tried it today, can’t say it was delicious but it wasn’t terrible either….I did how ever use a coffee bag & added the organic coconut oil ( not MCT oil). I like strong Coffe & think it might be better for my personal taste if the coffee was stronger…..I won’t give up will experiment to see if I can get it right! Can’t give feed back on any benefits as only just literally drank it. However for anyone thinking about doing the Keto Diet it’s fantastic & you never feel hungry….love it

  14. Been doing fat and protein coffee for three years consistently ,works very welk for me. I do three table spoons of pure capryl acid C8 mct oil , three table spoons of raw unpasteurized local butter, two table spoons of swerve ( to sweeten it ) , two scoops of True Nutrition grass fed Beef Protein isolate ( 60 grams of protein) , and three table spoons of organic coffee. All this in a blender and I fast for eight to nine hours before having my first meal. I am strict paleo.

    Madam, glad to know about official bulletproof coffee. I have been taking it with coconut oil. Thank you for enlightening about mct oil. I tasted with ghee now after giing through your post.

    tried it and it’s yummy…it’s my first time drinking bulletproof coffee..hesitant at first because it might taste oily but viola,it’s not!!!thanks for sharing your recipe 🙂

    I just love it, makes the coffee smooth and unctuous. I can do to 1pm without needing anything to eat I feel so satisfied. 👍🏼😆

  18. 5 stars
    Thanks for your post, which led me to your site! I ran out of cream, but remembered that I had ghee and MCT coconut oil. I sweetened it with pure monk fruit and added natural coconut and banana extracts. I lost 15 lbs. on WW but paleo is better suited to my overall well-being. Looking forward to exploring and learning more from you.

  19. Hi, my 14 year old and 17 year old would like to try bullet coffee for their weight loss plan but MCT oil is not recommended for under 18. Please could you kindly advise if your recipe is safe for them?

    1. Hey, I have never heard of why MCT oil wouldn’t be fine for people under 18, you can always just use some butter and coconut oil. My main concern would be more in regards to caffeine (or too much of it, which might not be the case) and if they are consuming this drink in place of a meal. A 14-17 age group has increased nutrient needs as it’s a big growth spurt period, so I would focus on making sure they are getting nutritious meals throughout the day and staying as active as possible to control any weight issues, but not skip meals at that age. That’s just my take as a nutritional adviser. I hope that helps!

  20. What happens if we use only coffee powder, ghee and hot water without mct oil and pink salt.

    1. You’ll still get buttery coffee and the fat will keep you satiated and slow down the caffeine release, so you can use those for sure.

    Very interesting. I tried this today and enjoyed it. And yes, I am a coffee lover! Could I ask you please as a qualified nutrition coach… I am concerned about the saturated fat in BP coffee. A decent knob of butter plus coconut oil seems like a lot. Have you done or heard of any research into cholesterol or heart health as a result of drinking this? Serious question, I enjoyed your article and I am keen to hear your response. Thanks!

    1. Hey Mitch,

      Dietary cholesterol has little to no effect on blood cholesterol levels in *most* people. More importantly, there is no significant link between the cholesterol you eat and your risk of heart disease. The whole ‘butter and saturated fat’ are bad for you is a very outdated concept that has been debunked and reviewes of previous studies as well new research shows it’s not the case. There are many other factors that affect the increase of the bad LDL cholesterol in the body (which is what you have to worry about) and it’s more to do with systemic inflammation, a generally poor diet high in sugar and carbohydrates, trans fats, smoking etc. Here is a quick snapshot: https://www.hsph.harvard.edu/nutritionsource/what-should-you-eat/fats-and-cholesterol/cholesterol/

      Caveat though! There is a small percentage of people with a hereditary condition called familial hypercholesterolemia which is characterised by higher than normal levels of LDL blood cholesterol. That’s the only group that might need to watch dietary cholesterol as such.

      I hope this helps!


  22. I’ll be making this tomorrow. Coffee Mate remains my last dietary vice, and this recipe seems like the bridge to freedom I seek. Thank you, Irena!

    PS — We Love Paleo is one of my favorite food docs. ☺

  23. I also add turmeric and cocao. It’s good for you, but the turmeric sure did make my plastic NutriBullet dome turn yellow. For the longest time, I have searched for something that would take away by brain fog and give me energy. I have seemingly found it in this great coffee recipe. However, one must be careful when consuming ghee. Though ghee helps with fatty liver disease, it is very high in cholesterol. This is not so good if you have strokes and high blood-pressure in your family. So I tend t go fairly light on the amount of ghee and coconut oil I use. But on the upside, this coffee recipe works WONDERS!!! Highly recommended.

  24. I use the same basic recipe except I use powdered MCT oil and a tablespoon of 100% Cacao .
    It like a cafe mocha. I drink it about 3 time a week.
    I lost 40 pounds on Keto 3 years ago with watching carbs and Bulletproof coffee I have kept it off.
    This lifestyle change has been great for me!

  25. Thank you for this post you put here on the bulletproof coffee. It is awesome I have a website called heavenly’s corner healing the way God intended and I’m going to put this on there so just so you know and yes. I put in my coffee Horlicks chocolate flavored and cinnamon and coconut oil and Glee butter and vanilla extract and in a collagen peptide and it is awesome I just make mine just like a coffee I don’t go blending it or anything I just put it all in a cup after I
