Combine the bananas, maple syrup, almond butter, applesauce, baking powder, and almond flour to form a batter. Stir in chocolate chips. Split the batter into two portions. To one portion, add 2 tablespoons of cacao powder and mix well. Layer both portions of batter into a 9x5 baking pan. Bake at 350 degrees Fahrenheit for 50-55 minutes.
