Bulletproof Coffee, or as my husband and I call it, “Brain Coffee,” is so smooth, creamy, and nutrient-dense! If you’ve heard the buzz (pun intended) but haven’t jumped on board yet, I dare you to give this delicious, full-bodied coffee a try! Plus I’ll share the benefits of drinking this coffee, also known as “Keto Coffee” and “Butter Coffee”.

  • Keto Butter Coffee Recipe

It takes me awhile to jump on a new trend. I had heard of Bulletproof® Coffee, but had no idea what it was. Coffee with butter in it sounded kind of gross, until my BFF came to visit and she explained the HUGE benefits to me, and now, after drinking it for months, no years, I’m sold. It’s so incredibly creamy, satisfying and filling!

Why you’ll love Bulletproof Coffee

  • Increased Focus! The good Lord knows I can use all I can get!
  • Reduced hunger and cravings: Uh, ditto to above!!
  • No Jitters! This is huge for me, I love coffee but I do not enjoy when coffee makes me vibrate!
  • No Sugar: I like my coffee sweet and I typically sweeten my coffee with a little organic turbinado sugar or stevia, but when I make this a latte…I add nothing!
  • Weight loss by way of ketosis, a metabolic state triggered by a lack of carbs that kicks fat-burning into overdrive
  • Suppressed hunger and vexing food cravings (read more about the science behind it here.)
  • Boosts cognitive function and mental clarity – we can all use a bit of that on those “one eye” open kind of mornings!
  • Steady lasting energy – no caffeine spike or crash and no jitters!

Bulletproof Coffee Keto Ingredients

  • Ground Bulletproof Coffee: (The Mentalist is my favorite roast) or other clean coffee.
  • MCT Oil: (WARNING! If this is the first time you are taking MCT or Brain Octaine oil, please start with 1 teaspoon (not tablespoon). Slowly increase over a week. Trust me on this one; it will cause you some major digestive turmoil!
  • Butter: Grass-fed, unsalted butter or grass-fed ghee.

Optional Add-Ins:

  • Collagen protein powder << this is the one I use. Or when I make for my chocolate loving hubby, I use a scoop of this chocolate collagen.
  • Organic grass-fed heavy cream; if not keto, may also use half and half or whole milk. Make sure your dairy is clean, without additives.
  • Vanilla Extract: the pure good stuff!

What not to add to your keto butter coffee

  • Do not add artificial sweeteners (Equal, Sweet N’ Low, Truvia, etc), honey, maple syrup or agave; sweeteners like this will mess with your blood sugar, causing energy dips that’ll wipe out the benefits of this coffee. If you must add something, try using an organic Stevia product – but try it without it first, I told you I like sweet coffee, and this coffee is so creamy and satisfying I don’t need to add anything sweet.
  • Plain ol’ coconut oil doesn’t work because it does not contain enough of the type of MCT oil that raises ketone levels, so you get a lot of calories but not a lot of fat-burning energy.

How to Make Bulletproof Coffee Recipe

Make your coffee. Brew 1 cup (8-12 ounces) of coffee using filtered water with 2 ½ heaping tablespoons of freshly ground (Bulletproof) Coffee Beans. I use a small French press, since I make it one cup at a time. Place coffee grounds in press, pouring 8-12 ounce (I do about 8) over the top, stir and place on plunger (don’t press down) – brew for 3 ยฝ – 4 minutes.

Pour hot water over coffee grounds in French Press.
Add boiling water to French press.
Place French press plunger on top and brew 3-5 minutes.
Allow coffee to brew.

Once coffee is finished brewing (3-4 minutes), depress plunger and pour coffee over the MCT oil, butter, and collagen powder. Place lid on blender.

Step 2 – Make Butter Coffee

While your coffee is brewing froth your cream (optional) – but so yummy!

In a blender, add Brain Octane Oil. Add 1 teaspoon to 2 tablespoons of Brain Octane oil, remember — start slowly, it’s powerful stuff!

Add 1-2 tablespoons of grass-fed, unsalted butter (I sometimes use salted grass-fed butter) or grass-fed ghee. I don’t mind the salt, but if you are sensitive, be sure to use unsalted butter.

Pour in one scoop of collagen powder if desired.

Add desired amount of MCT oil and butter.
Add MCT oil and butter to blender.
Pour in coffee and add collagen if adding.
Add coffee and collagen if adding.
Process in blender until smooth.
Whir in blender until creamy.
Whir in blender, being careful when opening.
Whir it up, be careful, opening slowly as pressure builds

Blend. Mix it all in a blender for 20-30 seconds until it looks like a creamy latte. There will be a good amount of foam on top.

If using a smoothie-sized blender, like a Ninja (my fave) or Nutribullet, be careful when opening the top. I unscrew it very slowly; the heat builds pressure, and it will “spit” and “spurt” when you open the lid. Sometimes, I place a towel or paper towel over the top, and as long as you release the lid slowly, you shouldn’t have any problems. You can also use a regular-sized blender and shouldn’t experience the pressure build. 

Pour into mug and if desired, spoon a few tablespoons of the frothed foam on top. Enjoy!

Butter Coffee Recipe Variations and Substitutions

  1. Collagen Protein Powder A full spectrum of amino acids derived from grass-fed beef, collagen powder is tasteless and dissolves completely in liquid. It aids healthy tissue repair, which means good things for your gut, skin, hair, and joints – if you don’t add it to your Bulletproof then add to your smoothies or morning coffee.
  2. Turmeric This popular yellow spice is known for its antioxidant and anti-inflammatory properties. Turmeric is pretty strong and it could take away from the rich flavor of Bulletproof Coffee. If you try Turmeric I’d suggest you omit the coffee and use the rest of the ingredients making a “bulletproof” Golden Milk.
  3. Vanilla adds classic flavor with a boost of antioxidants that help aid in cognitive enhancement. Try making your own, ghee – it’s delicious! Add 1 teaspoon pure vanilla to the blender before blending.
  4. Chocolate Powder Make your Bulletproof Coffee into a mocha and add a ton of performance-boosting polyphenols while you’re at it! High-quality chocolate just add 1 teaspoon of organic chocolate powder.
  5. Ceylon Cinnamon Adding 1 teaspoon Cinnamon directly to the grounds before brewing can help you regulate your blood sugar and reduce insulin resistance, all while enhancing motivation, performance, and alertness.

Bulletproof Coffee Keto FAQs

Why you should use grass-fed butter

Grass-fed butter is nutrient-dense; it’s in the grass-feeding that you gain these nutrients. It’s also what gives the coffee its rich, creamy consistency. If you are lactose or casein-intolerant, try ghee instead.

Why can’t I use any coconut oil?

Brain octaine oil or MCT oil is much more effective as it doesn’t raise ketones. Regular coconut oil will raise ketones, those fat-burning, brain-boosting molecules in your body. So regular coconut oil won’t cut it.
This oil is composed of a special type of medium-chain triglyceride (MCT) derived from coconut oil. But all MCTs are not created equal. There are four different strains of MCTs and they each do different things, not all good. Allergic to coconuts? This process of highly refining this coconut oil removes the proteins that cause allergic reactions, but be sure to check with your Dr. before trying.
You can read more about how MCTs work vs. brain octaine oil here.

Notes

DAIRY | Make sure you are using organic, whole full fat milk, cream or half and half. No additives should be in the ingredients list, ever!
If using a smoothie-sized blender, like a Ninja (my fave) or Nutribullet, be careful when opening the top, unscrew it very slowly, the heat builds pressure and it will “spit” and “spurt” when you open the lid. Sometimes I place a towel or paper towel over the top, as long as you release the lid slowly, you shouldn’t have any problems. You can also use a regular-sized blender, and you shouldn’t experience this same effect.
