Method
- Preheat your oven to 375°F (190°C). Grease or line a 9x13 inch baking pan with parchment paper.
- In a large bowl, beat the sugar and butter until creamy. Add the sour cream, eggs, mashed bananas, and vanilla extract. Blend until smooth.
- Add the flour, baking soda, and salt to the wet ingredients. Mix until just combined.
- Pour the batter into the prepared pan. Bake for 35-40 minutes, or until a toothpick inserted into the center comes out clean. Let the brownies cool completely before frosting.
- To make the frosting, melt the butter in a medium skillet over medium-low heat until foamy and lightly browned. Carefully pour the browned butter into a large bowl or the bowl of a stand mixer.
- Add the powdered sugar and vanilla extract to the browned butter. Mix to combine.
- With the mixer on low speed, gradually add the milk until a smooth and creamy frosting forms. Beat on high speed for 3-5 minutes until light and fluffy.
- Spread the frosting evenly over the cooled brownies. Sprinkle with cinnamon.

Notes
Store frosted banana brownies covered in an airtight container at room temperature for up to 5 days. For longer storage, freeze the frosted bars by wrapping them tightly in plastic wrap and then foil for up to 3 months. Thaw before serving.
