1. Preheat your oven to 350°F and line a baking pan with parchment paper or lightly grease it.
2. In a large mixing bowl, combine mashed bananas, applesauce, maple syrup (or honey), almond milk, brewed coffee, and vanilla extract. Mix well until smooth. Add oat flour, cocoa powder, baking powder, baking soda, and salt. Mix until well combined. Fold in dark chocolate chips if using.
3. Pour the batter into the prepared baking pan and spread it evenly. Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Remove from the oven and let it cool completely in the pan.
4. In a small bowl, mix together dairy-free yogurt, vanilla or chai protein powder, ground cinnamon, ginger, cardamom, cloves, and maple syrup. Adjust sweetness to your preference.
5. Once the chocolate coffee base has cooled, spread the chai protein yogurt frosting evenly over the top and sprinkle with cinnamon.
