Bulletproof Collagen Protein Bars are the easiest way to get pastured protein on the go without sapping your macros. But if you don’t tolerate nuts, these homemade collagen protein bars are the next best thing. Just like regular collagen bars, this recipe is packed with grass-fed Collagen Protein to give you the building blocks for healthy skin, bones and joints, plus energizing Brain Octane MCT oil.

The best thing about these nut-free protein bars is that they’re easy to customize. Once you make your coconut butter base, it’s ready to pair with just about any mix-in under the sun. You can try the suggestions in the recipe below, or get wild and include dark chocolate chunks, pumpkin pie spice, cinnamon, sea salt or chunks of cacao butter.

Serve your homemade collagen protein bars with Bulletproof Coffee, pack them in your lunch or enjoy as a sweet afternoon snack.
