  • ยฝ cup unsalted butter, softened (113g)
  • ยพ cup granulated sugar (150g)
  • ยผ cup light brown sugar, packed (50g)
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla extract
  • ยฝ teaspoon banana extract (optional but recommended)
  • 1ยฝ cups all-purpose flour (190g)
  • 1 teaspoon baking soda
  • ยฝ teaspoon baking powder
  • ยฝ teaspoon salt
  • ยฝ cup sour cream (120g)
  • 8 oz cream cheese, softened (226g)
  • ยฝ cup unsalted butter, softened (113g)
  • 3 cups powdered sugar (360g)
  • 1 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. Preheat oven to 350ยฐF (175ยฐC). Grease two 8-inch round cake pans and line bottoms with parchment paper.
  2. In a medium bowl, mash bananas with a fork until mostly smooth with a few small lumps. Set aside.
  3. In a large bowl, beat softened butter, granulated sugar, and brown sugar together until light and fluffy, about 3-4 minutes.
  4. Add eggs one at a time, beating well after each. Mix in vanilla extract and banana extract (if using).
  5. In a separate bowl, whisk together flour, baking soda, baking powder, and salt.
  6. With mixer on low, add one-third of dry ingredients to butter mixture, mixing just until combined. Add half of sour cream and mix. Repeat with another third of dry ingredients, remaining sour cream, and final dry ingredients. Mix until just combined.
  7. Gently fold mashed bananas into batter with a rubber spatula until no streaks remain.
  8. Divide batter evenly between prepared pans. Bake for 28-32 minutes, until a toothpick inserted in center comes out clean or with moist crumbs.
  9. Cool cakes in pans for 10 minutes, then turn out onto a cooling rack. Remove parchment and cool completely.
  10. For frosting: Beat softened cream cheese and butter together until smooth. Add powdered sugar one cup at a time, beating on low. Mix in vanilla and salt. Beat on medium-high for 2 minutes until fluffy.
  11. Place one cake layer on serving plate. Spread about ยฝ cup frosting on top. Add second layer. Apply thin crumb coat, refrigerate 15 minutes, then apply final layer of frosting.

Notes

Use very ripe bananas with brown spots for best flavor. Room temperature ingredients are crucial for proper texture. For a sheet cake version, bake in a 9×13 pan for 35-40 minutes. Cake can be frozen unfrosted for up to 3 months.
