How to Make Bulletproof Coffee Blocks for Busy Mornings

Never suffer a morning without Bulletproof Coffee again: These coffee blocks cut down your prep time so you can enjoy a piping hot cup in just minutes a day.

What are Bulletproof Coffee blocks? True to the original recipe, they’re pre-mixed cubes containing grass-fed butter and Brain Octane Oil. Simply add to your blender with fresh brewed coffee, and blend as normal.

If you customize your Bulletproof Coffee with extra flavors or supplements, coffee blocks can save you precious minutes in the morning. In addition to your buttery base, you can blend almost any flavorful upgrade into these cubes.

This recipe for Bulletproof Coffee blocks offers suggested measurements for butter and oil, but you can adjust depending on your taste. Avoid adding too much oil, though: MCT oils melt very quickly after freezing, so you could end up with mushy or even liquid cubes. If your coffee blocks won’t set, mix and freeze them again with more butter.

Take Bulletproof Coffee blocks to work, or simply stash in your home freezer. No matter where you take them, you can always have a source of quality fats on hand.
