Preheat the oven to 350 degrees. Line a baking sheet with parchment paper or a nonstick baking mat.
In a large bowl, mix together the protein powder, oats, whole wheat flour, baking powder, and cinnamon.
Make a well in the center of the dry ingredients and add the coconut oil, vanilla, egg, and honey.
Stir until just combined. Fold in the chocolate chips.
Chill the dough for at least 30 minutes.
Shape the dough into 12 equal sized cookies. Place the cookies on the cookie sheet 2 inches apart; you may have to bake in batches.
Bake for 12-14 minutes or until edges are browned. Repeat with remaining dough.
Cool for 10 minutes, then serve.
