How to make Banana Bread Brownies
- Prep. Preheat the oven to 350°F and grease an 8X8-inch baking dish liberally with baking spray or butter.
- Cream. In the bowl of an electric mixer, cream together the butter and sugars on high speed until fluffy and noticeably lighter in color (about 2-3 minutes).
- Add the remaining wet ingredients. Reduce the mixer to medium speed and mix in the sour cream. Mix in the eggs, one at a time, followed by the vanilla.
- Combine the dry ingredients. In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon.
- Put it all together. On low speed, gradually mix the dry ingredients into the wet ingredients. Finally, mix in the bananas and fold in the walnuts.
- Bake. Spread the batter evenly into the prepared baking dish and bake for 25 minutes or until a toothpick inserted into the center comes out clean.
- Cool. Remove the brownies from the oven and allow them to cool completely. In the meantime, make the frosting.
- Make the cream cheese frosting. Beat the cream cheese and butter until smooth and creamy. Add the powdered sugar, one cup at a time, beating until smooth after each addition. Stir in the vanilla extract.
- Frost the brownies. Once the brownies are completely cool, spread the cream cheese frosting evenly over the top.
