Ingredients

Scale

Brownie Batter

  • 3 medium ripe bananas (preferably overripe for optimal flavor)
  • 1 cup sour cream (or Greek yogurt as a substitute)
  • 1 teaspoon vanilla extract
  • 1 cup granulated sugar
  • ½ cup unsweetened cocoa powder
  • 2 large eggs
  • 1 cup all-purpose flour (or gluten-free flour blend)
  • ½ cup chopped walnuts (optional, can substitute with chocolate chips)
  • ½ cup unsalted butter, melted

Frosting

  • 2 cups powdered sugar
  • ¼ cup heavy cream
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat and prepare pan: Preheat your oven to 350°F (175°C) and grease a 9×9-inch baking pan thoroughly to prevent sticking.
  2. Mash bananas and mix wet ingredients: In a large mixing bowl, mash the ripe bananas until smooth. Stir in sour cream and 1 teaspoon of vanilla extract until the mixture is well combined.
  3. Combine sugar, cocoa, and eggs: In a separate bowl, whisk together the granulated sugar, unsweetened cocoa powder, and eggs until the mixture becomes fluffy and paler in color, indicating well-aerated batter.
  4. Fold banana mixture with dry ingredients: Gently fold the banana and sour cream mixture into the cocoa mixture. Then carefully incorporate the flour and chopped walnuts, mixing just until combined to avoid overworking the batter.
  5. Prepare for baking: Pour the finished batter evenly into the greased baking pan. Use a spatula to smooth the top for even baking.
  6. Bake the brownies: Place the pan in the preheated oven and bake for 25 to 30 minutes. Check doneness by inserting a toothpick into the center — it should come out with a few moist crumbs but not wet batter.
  7. Cool before frosting: Allow the brownies to cool in the pan for about 10 minutes, which helps them set and makes them easier to frost.
  8. Prepare frosting and finish: In a bowl, mix the powdered sugar, heavy cream, and vanilla extract until smooth. Spread the frosting evenly over the cooled brownies before slicing and serving.

Notes

  • For best flavor and texture, use overripe bananas with brown spots.
  • You can substitute sour cream with Greek yogurt to reduce fat.
  • Walnuts can be swapped with chocolate chips or omitted for nut-free brownies.
  • Check brownies a few minutes before the minimum baking time to prevent overbaking.
  • Allow brownies to cool completely before refrigerating leftovers to maintain moisture.
