Tips: baking with bananas
It’s important that you use overripe bananas for this recipe. The skin of the banans should have brown speckles or even be turning dark brownish-black. This ensures that the bananas mash smoothly and are extra sweet.
You will need 2-3 bananas to make 1 cup.
Mash the bananas using a fork or potato masher.
I mash the bananas on a paper plate then fold the plate to slide the mashed banana into the measuring cup.
Topping options
This cake is topped with a generous amount of chocolate frosting. If you’d like less frosting you can cut the frosting recipe in half.
Top the frosted cake with chocolate shavings, chocolate curls, chocolate sprinkles, or sliced banana. Wait to add the banana until you’re serving it.
Serving and storage
This cake is best served at room temperature.

Instructions
Cake:
Preheat oven to 350°F with a rack in the center of the oven,
Combine flour, cocoa, baking powder, baking soda, and salt. Set aside.
Using a hand mixer or stand mixer fitted with the paddle attachment, beat butter, granulated sugar, and brown sugar until creamy and combined. Add mashed banana, eggs, and vanilla beating until well combined and scraping the sides and bottom of the bowl as necessary. Add half of the flour mixture, beating until combined, add milk then remaining flour beating well between each addition and scarping the sides and bottom of the bowl and beater.
Transfer the batter into a greased 9×9 square baking pan and spread into an even layer. Bake for 23-27 minutes, until a toothpick inserted into the center comes out clean. Place the pan on a wire rack to cool completely.
Frosting:
Using a hand mixer or stand mixer fitted with the paddle attachment, beat butter until smooth. Add half the powdered sugar and all the cocoa powder. Beat in vanilla and half the milk followed by remaining powdered sugar. Add as much more milk as you need to get your desired consistency. Turn speed up to medium-high and beat for 30 seconds. Spread the frosting on top of the cooled cake.
Notes
Frosting: This makes enough frosting to add a thick layer on top of the cake (as pictured). If you’d prefer a thinner layer of frosting you can cut the frosting recipe in half.
