Use a rubber spatula to stir together the creamy peanut butter, honey, rolled oats, protein powder, and cocoa powder in a large mixing bowl

Line an 8x8 baking dish with wax paper

Spread the chocolate protein bar batter evenly into the pan

Melt the chocolate chips until smooth and spread evenly over the top of the protein bars with a rubber spatula

Sprinkle with flaked sea salt before the chocolate hardens

Chill the protein bars in the fridge until the chocolate is set (1-2 hours)

Slice into 16 squares

Store leftover bars in an airtight container in the fridge or freezer
