Ingredients

Scale

Wet Ingredients

  • 1 ½ cups sugar
  • 1 cup sour cream
  • ½ cup unsalted butter, softened
  • 2 eggs
  • 3 ripe bananas, mashed
  • 2 tsp vanilla extract

Dry Ingredients

  • 2 cups all-purpose flour
  • 1 tsp baking soda
  • ¾ tsp salt

Add-ins

  • ½ cup walnuts, chopped

Instructions

  1. Preheat and prepare pan: Preheat your oven to 375°F (190°C) and grease a 9×13 inch baking pan thoroughly to prevent sticking.
  2. Mix wet ingredients: In a mixing bowl, combine the sugar, sour cream, softened butter, and eggs using an electric mixer until the mixture becomes smooth and creamy. Then, mix in the mashed bananas and vanilla extract until evenly incorporated.
  3. Add dry ingredients: Gradually add the flour, baking soda, and salt into the wet mixture, stirring gently just until combined to avoid overmixing and keep the brownies tender.
  4. Fold in walnuts: Gently fold the chopped walnuts into the batter, ensuring even distribution without breaking them up too much.
  5. Bake: Pour the batter into the prepared baking pan and place it in the preheated oven. Bake for 20 to 30 minutes or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
  6. Cool and serve: Allow the brownies to cool slightly in the pan before cutting into squares. Enjoy them plain or with your favorite frosting, ice cream, or whipped cream topping.

Notes

  • Use very ripe bananas for the best natural sweetness and moist texture.
  • Do not overmix the batter after adding flour to keep brownies tender.
  • Walnuts can be omitted or substituted with pecans or chocolate chips as preferred.
  • Check the brownies at 20 minutes to avoid overbaking and drying out.
  • Store leftovers in an airtight container at room temperature for up to 3 days or refrigerate for longer freshness.
