Ingredients

  • 2 cups all-purpose flour
  • 1 teaspoon baking powder
  • 1 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 teaspoon ground cinnamon
  • 1/2 cup unsalted butter, softened (for cake)
  • 1 cup granulated sugar
  • 1/2 cup packed brown sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 cup mashed ripe bananas
  • 1/2 cup sour cream
  • 8 oz cream cheese, softened (for frosting)
  • 1/2 cup unsalted butter, softened (for frosting)
  • 2 cups powdered sugar (for frosting)

Instructions

  • Preheat oven to 350°F (175°C). Grease and flour a 9x13-inch baking dish.
  • Whisk flour, baking powder, baking soda, salt, and cinnamon in a bowl. Set aside.
  • Cream unsalted butter (for cake), granulated sugar, and brown sugar until light and fluffy, about 3-4 minutes.
  • Add eggs one at a time, beating well. Mix in 1 teaspoon vanilla extract.
  • Stir in mashed bananas and sour cream until combined.
  • Gradually add dry ingredients to wet mixture. Mix until just combined.
  • Pour batter into prepared dish. Bake for 30-35 minutes until a toothpick comes out clean.
  • Let cake cool completely. In a separate bowl, beat cream cheese, unsalted butter (for frosting), and powdered sugar until smooth and creamy. Frost cooled cake and slice.
  • For best results, store in airtight container at room temperature for 1 day or refrigerate for up to 3 days.

Notes

Use overripe bananas with brown spots for maximum sweetness.
Frosting can be refrigerated in an airtight container for up to 3 days.
For even layers, level cake crosswise before frosting.
