Creating these Banana Pudding Brownies is straightforward if you follow these simple steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and grease a 9×13 inch baking pan.
2. Mix Wet Ingredients: In a large bowl, combine the melted butter, granulated sugar, and brown sugar. Mix until smooth.
3. Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract. Mix until combined.
4. Combine Dry Ingredients: In another bowl, whisk together the flour, cocoa powder, baking powder, and salt.
5. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, stirring until just combined.
6. Fold in Bananas: Gently fold in the mashed bananas until evenly distributed in the batter.
7. Pour Batter: Pour the brownie batter into the prepared baking pan, spreading it evenly.
8. Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
9. Cool: Allow the brownies to cool in the pan for 20-25 minutes before proceeding to the next step.
10. Prepare Pudding: In a separate bowl, whisk together the vanilla pudding mix and milk until thickened. Let it sit for about 5 minutes.
11. Spread Pudding: Once the brownies are cool, spread the thickened pudding over the top evenly.
12. Top with Whipped Cream: Add a layer of whipped cream on top of the pudding layer.
13. Garnish: Decorate with sliced bananas on top for an appealing finish.
