Bananas Foster Layer Cake Recipe

Indulge in the decadence of a Bananas Foster Layer Cake, featuring layers of moist cake infused with caramelized banana flavor, topped with a luscious buttercream frosting and a generous drizzle of rum-infused caramel sauce.


For the Cake:

  • 2 ripe bananas
  • 1 cup granulated sugar
  • 1/2 cup unsalted butter, softened
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 cup buttermilk

For the Frosting:

  • 1 cup unsalted butter, softened
  • 4 cups powdered sugar
  • 2 tablespoons heavy cream
  • 1 teaspoon vanilla extract

For the Bananas Foster Sauce:

  • 3 tablespoons unsalted butter
  • 1/2 cup brown sugar
  • 1/4 cup dark rum
  • 2 ripe bananas, sliced


  1. Preheat your oven to 350°F (175°C). Grease and flour three 9-inch round cake pans.
  2. In a small saucepan over medium heat, melt 1/2 cup of butter. Add sliced bananas and cook until caramelized, about 2-3 minutes. Remove from heat and set aside to cool.
  3. In a mixing bowl, cream together the softened butter and sugar until light and fluffy. Beat in eggs, one at a time, then stir in vanilla extract.
  4. In a separate bowl, combine flour, baking soda, and salt. Gradually add the dry ingredients to the creamed mixture, alternating with buttermilk. Fold in the caramelized bananas.
  5. Divide the batter evenly among the prepared cake pans. Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Remove from oven and let cool in pans for 10 minutes before transferring to wire racks to cool completely.
  6. While the cakes are cooling, prepare the frosting. In a mixing bowl, beat softened butter until creamy. Gradually add powdered sugar, alternating with heavy cream and vanilla extract, until smooth and spreadable.
  7. To make the Bananas Foster sauce, melt 3 tablespoons of butter in a skillet over medium heat. Stir in brown sugar until dissolved. Add sliced bananas and cook until softened. Carefully add rum and let it simmer for a minute until slightly reduced.
  8. Once the cakes are completely cooled, assemble the layer cake by spreading frosting between each layer. Pour the Bananas Foster sauce over the top layer of the cake, allowing it to drip down the sides.
  9. Serve slices of this indulgent Bananas Foster Layer Cake and enjoy the rich flavors of caramelized bananas and rum-infused sauce!
