No-bake peanut butter protein bars taste like a peanut butter cup, but pack 13 grams of protein in each small square! Easy to make with simple ingredients like peanut butter, honey, collagen peptides, and dark chocolate.
Line an 8-inch by 4-inch loaf pan with parchment paper.
In a medium bowl, combine peanut butter, honey, coconut oil and vanilla extract.Melt the chocolate and spread it evenly over the surface of the peanut butter mixture. Chill until very firm before slicing.
Stir in the ground flaxseed and collagen powder. Once you can't stir anymore, use your hands to finish combining the dough.
Press firmly and evenly into the lined loaf pan.
In a glass bowl, melt the chocolate chips or chocolate pieces either in 30-second intervals in the microwave or over a pan of simmering hot water on the stovetop. Once it's smooth and creamy, spread it evenly over the surface of the peanut butter mixture. Use a knife to lightly score the chocolate layer into bars that you will cut later.
Chill until very firm before slicing. See the tip below for how to slice without cracking the chocolate layer.
Store in the fridge or freezer.
Notes
To make clean cuts and avoid cracking the chocolate layer, use a knife to lightly score the chocolate before transferring it to the fridge to chill for 45 - 60 minutes.When you're ready to slice into bars, dip a sharp knife into a glass of hot water to warm it, then carefully slice using the scored lines you had made earlier.
