Cake

Buttercream Frosting

Method

Cake Preparation

  1. 1

    Preheat the Oven

    Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.

  2. 2

    Prepare Bananas

    In a large bowl, mash the ripe bananas until smooth. Set aside.

  3. 3

    Cream Butter and Sugar

    In a separate mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy.

  4. 4

    Add Eggs and Vanilla

    Beat in the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.

  5. 5

    Combine Wet and Dry Ingredients

    Gradually add the mashed bananas to the creamed mixture and mix until well combined. In another bowl, sift together the flour, baking powder, baking soda, and salt. Slowly add the dry ingredients to the wet mixture, stirring until just combined.

  6. 6

    Fold in Walnuts

    Gently fold in the chopped walnuts until evenly distributed throughout the batter.

  7. 7

    Bake the Cake

    Pour the batter evenly into the prepared cake pans. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.

  8. 8

    Cool the Cakes

    Once baked, allow the cakes to cool in the pans for 10 minutes before transferring to a wire rack to cool completely.

Buttercream Frosting Preparation

  1. 9

    Make the Buttercream

    In a mixing bowl, beat the unsalted butter until creamy. Gradually add the powdered sugar, mixing on low speed until combined.

  2. 10

    Add Cream and Vanilla

    Add the heavy cream and vanilla extract, then beat on high speed for about 3 minutes until the frosting is light and fluffy.

  3. 11

    Incorporate Walnuts

    Fold in the chopped walnuts into the frosting for added texture and flavor.

Assembly

  1. 12

    Frost the Cake

    Once the cakes have cooled completely, place one layer on a serving plate. Spread a generous amount of buttercream frosting on top, then place the second layer on top of the frosting.

  2. 13

    Final Touch

    Use the remaining frosting to cover the top and sides of the cake evenly. Decorate with additional walnuts if desired.
