Preheat oven to 400°F.
Add the 3 ripe bananas, ½ cup almond or peanut butter, 2 eggs, 1 tsp baking powder, and 1 tsp vanilla extract to a bowl and mix together.
Optionally, add chocolate chips inside the batter or drizzle melted chocolate on top for extra sweetness.
Bake for 20-30 minutes, checking at 22 minutes since the oven runs hot.
