Ingredients

Scale
  • 1 3/4 cups (220 g) all-purpose flour
  • 1 cup (200 g) granulated sugar
  • 1/2 cup (115 g) unsalted butter, softened (or 1/2 cup oil)
  • 2 large eggs
  • 3 ripe bananas, mashed (about 1 1/2 cups)
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 tsp vanilla extract
  • 1/2 cup sour cream or plain yogurt
  • 8 oz (225 g) cream cheese, softened
  • 1/4 cup (60 g) butter, softened
  • 2 cups (240 g) powdered sugar, sifted
  • 1 tsp vanilla extract (for frosting)

Instructions

  1. Preheat the oven to 350°F (175°C). Grease and flour a 9×13-inch pan or line a loaf pan.
  2. In a bowl, cream together butter and sugar until light. Add eggs one at a time, then mix in vanilla.
  3. Stir in mashed bananas and sour cream until smooth.
  4. In a separate bowl, whisk flour, baking soda, and salt. Fold dry ingredients into wet until just combined. Do not overmix.
  5. Pour batter into the prepared pan and smooth the top. Bake 25–35 minutes for a 9×13 pan, or 50–60 minutes for a loaf, until a toothpick comes out clean. Let cool completely.
  6. For the frosting, beat cream cheese and butter until smooth. Add powdered sugar and vanilla, and mix until creamy. Spread over cooled cake. Chill 15–30 minutes to set before slicing.

Notes

Use very ripe bananas for the best flavor and don’t overmix the batter to keep the cake tender. Store the frosted cake in the fridge for up to 4 days.
