Preheat oven to 350 degrees. Prepare two baking sheets with a silicone baking mat or parchment paper.
In a large mixing bowl, mash the banana. Add the egg and use a fork to whisk together the egg and banana until well combined.
Mix in the brown sugar, honey, softened butter, and vanilla. When combined, stir in the unsweetened cocoa powder.
Add the remainder of the dry ingredients – oats, wheat flour, salt, baking powder, and baking soda. Stir until just combined, then fold in the chocolate chips.
Portion out cookie dough on the baking sheets into approximately 18 cookies. Place in the oven and bake for 9-11 minutes, or until the cookies have set. (Mine come out perfect right at 10 minutes). Enjoy!
