Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking dish.

In a mixing bowl, mash the ripe bananas until smooth.

In another bowl, whisk together flour, baking powder, and salt.

In a separate bowl, mix melted butter, sugar, eggs, and vanilla extract; combine well before adding mashed bananas.

Gradually mix in the dry ingredients until just combined.

Pour the batter into the prepared dish and bake for 25-30 minutes or until a toothpick comes out clean.

Let cool completely before frosting with a mixture made by beating softened cream cheese and powdered sugar until smooth.
