Ingredients

For the banana cake:

  • 1 stick unsalted butter room temperature (115g)
  • 1 cup granulated sugar (200g)
  • 2 large eggs room temperature
  • 1 1/2 cups mashed ripe bananas 3 medium ones
  • 1 cup buttermilk or 1 cup milk + 1 tbsp lemon juice (240ml)
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour (250g)
  • 1 tsp baking soda
  • 1/4 tsp salt

For the frosting:

  • 3/4 stick unsalted butter room temperature (90g)
  • 1 1/2 cups confectioners' sugar sifted (160g)
  • 1 tsp vanilla extract
  • 4 oz cold mascarpone (113g)

Instructions

  • Preheat your oven to 350°F (180°C). Grease a 9x13-inch baking pan. Set aside.
  • In the bowl of a stand mixer fitted with the paddle attachment, cream butter and sugar together at medium-high speed until light and fluffy, about 3-4 minutes.
  • Add eggs, mashed bananas, buttermilk, and vanilla extract. Mix at low speed until combined.
  • In a small bowl combine flour, baking soda, and salt.
  • Add flour mixture in three additions to the wet mixture, mix just until combined.
  • Pour batter into the baking dish and bake for 20-25 minutes. When the cake is done a skewer inserted in the middle should come out clean with only a few crumbs attached. Let the cake cool down completely before frosting it.
  • To make the frosting, beat together butter and confectioners' sugar in the bowl of a stand mixer fitted with the paddle attachment until light and fluffy.
  • Add vanilla extract and mascarpone and beat until blended. Frost cooled cake.
