We’ve been making Bulletproof Coffee every day for over a decade. And our recipe has changed over time. It’s not just the coffee and fat though – we’ve been working on the right ratios and found that 1 tsp. MCT oil powder and 2 tablespoons of grass-fed unsalted butter are what works best for most folks starting out.


  • 8 fl oz water

  • 1 cup Bulletproof coffee

  • 1 tsp. to 2 tbsp. Brain Octane C8 MCT oil

  • 1-2 tbsp. grass-fed, unsalted butter or 1-2 tsp. Grass-Fed Ghee


  • 1 cup (8-12 ounces) of coffee using Bulletproof coffee beans.
  • Add coffee
  • Brain Octane C8 MCT oil and butter or ghee to a blender.
  • Blend for 20-30 seconds until it looks like a creamy latte.
  • Enjoy!
