1. Preheat and Prepare:
Preheat your oven to 375°F (190°C).
Lightly grease an 8×8-inch baking dish or line it with parchment paper.
2. Mix the Dry Ingredients:
In a large bowl, whisk together the oats, cocoa powder, baking powder, cinnamon, and salt.
3. Mix the Wet Ingredients:
In another bowl, mash the bananas and mix them with the milk, maple syrup, egg, vanilla, and melted coconut oil or butter until smooth.
4. Combine:
Pour the wet ingredients into the dry ingredients and stir until well combined.
Fold in chocolate chips and nuts if using.
5. Assemble:
Pour the oatmeal mixture into the prepared baking dish. Spread it evenly with a spatula.
Arrange banana slices on top and sprinkle with additional chocolate chips or nuts if desired.
6. Bake:
Bake for 35-40 minutes, or until the top is set and slightly firm to the touch.
7. Serve:
Let the bake cool for 10 minutes before slicing into squares or scooping into bowls.
Serve warm as-is or with a drizzle of milk, yogurt, or peanut butter.
Storage:
Store leftovers in an airtight container in the fridge for up to 5 days.
Reheat in the microwave or oven before serving.
