Ingredients

Scale

For the Cake:

  • 1 ½ cups all-purpose flour
  • 1 tsp baking soda
  • 1 tsp baking powder
  • ½ tsp salt
  • ½ cup unsalted butter, softened
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract
  • 3 ripe bananas, mashed
  • ½ cup sour cream or plain Greek yogurt
  • ½ cup chopped walnuts (plus extra for garnish)

For the Frosting (Optional):

  • 1 cup powdered sugar
  • ½ cup unsalted butter, softened
  • 1 tsp vanilla extract
  • 23 tbsp heavy cream (to adjust consistency)

Instructions

  • Preheat Oven:
    • Preheat your oven to 350°F (175°C). Grease and flour a 9-inch round or square cake pan.
  • Mix Dry Ingredients:
    • In a medium bowl, whisk together the flour, baking soda, baking powder, and salt. Set aside.
  • Cream Butter and Sugar:
    • In a large mixing bowl, cream the softened butter and granulated sugar together using an electric mixer until light and fluffy, about 3-4 minutes.
  • Add Eggs and Vanilla:
    • Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
  • Incorporate Bananas and Sour Cream:
    • Add the mashed bananas and sour cream (or Greek yogurt) to the batter, mixing until well combined.
  • Add Dry Ingredients and Walnuts:
    • Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Fold in the chopped walnuts.
  • Bake the Cake:
    • Pour the batter into the prepared pan and smooth the top. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean. Let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
  • Make the Frosting (Optional):
    • In a medium bowl, beat the softened butter until smooth. Gradually add the powdered sugar and beat until fluffy. Add the vanilla extract and heavy cream, one tablespoon at a time, until the frosting reaches your desired consistency.
  • Frost and Garnish:
    • Once the cake has cooled completely, spread the frosting on top. Garnish with extra chopped walnuts if desired.

Notes

  • This cake can be served plain or with the optional frosting for a sweeter treat.
  • Store leftovers in an airtight container at room temperature or in the refrigerator for a longer shelf life.
