Instructions
Step 1: Preheat & Prepare
-
Preheat your oven to 350°F (175°C).
-
Grease a 9×9-inch baking pan or line it with parchment paper for easy removal.
Step 2: Make the Banana Bread Layer
-
In a large bowl, mash the bananas until smooth.
-
Add melted butter, sugar, egg, and vanilla extract. Mix well.

In a separate bowl, whisk together flour, baking powder, baking soda, salt, and cinnamon.

Gradually fold the dry ingredients into the banana mixture until just combined. Set aside.

In another bowl, whisk together melted butter, sugar, eggs, and vanilla.

Sift in cocoa powder, flour, and salt. Stir until smooth and glossy.
Step 4: Layer & Swirl

Gently pour the brownie batter on top, spreading it to cover the banana layer.
-
Use a knife or toothpick to swirl the two batters slightly for a marbled effect.

(Optional) Sprinkle chocolate chips or nuts on top.
Step 5: Bake
-
Bake for 28-32 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs.

Let cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
