Course: Cake, Others

Ingredients

  • 1 1/2 cups banana very ripe, mashed, about 4 large
  • 3 cups cake flour see post for homemade alternative
  • 2 teaspoons baking powder
  • 1 1/2 teaspoons baking soda
  • 1/2 teaspoon ground cinnamon
  • 1 teaspoon salt
  • 2 butter sticks, at room temperature
  • 2 teaspoons vanilla extract
  • 1 cup granulated sugar
  • 1 cup light brown sugar packed
  • 4 egg large, at room temperature
  • 3/4 cup sour cream full-fat
  • 3/4 cup milk whole
For the Salted Honey Peanut Butter Frosting:
  • 8 ounces cream cheese full-fat, very soft
  • 4 ounces unsalted butter 1 stick; very soft
  • 1 cup peanut butter creamy
  • 1 tablespoon honey
  • 1/2 teaspoon sea salt flaky
  • 4 cups confectioners' sugar
  • 2 tablespoons heavy cream

Instructions

    Cup of Yum
  1. Preheat oven to 350° (F). Grease and flour two 9" spring form pans OR three 9" round cake pans. The spring form pans are deep enough to hold the batter split in two, but if you don't own them, just make it into three cakes - we don't want oven overflow!
  2. Mash bananas well and place them in a small bowl; set aside.
  3. In a medium bowl, mix flour, baking powder, baking soda, cinnamon and salt; set aside.
  4. In a large bowl using a handheld electric mixer, or using a standmixer fitted with the paddle attachment, beat butter, vanilla, and both sugars until light and fluffy; about 5 minutes (don't skimp on time here!). Add in the eggs, one at a time, beating well after each addition.
  5. On low speed, beat in the flour mixture alternately with the sour cream and milk. Fold in bananas.
  6. Divide batter evenly among the prepared pans and bake in preheated oven for 35 minutes, or until a cake tester inserted in center comes out clean. Allow the cakes to cool in the pans for 10 minutes before gently running a knife around the edges to loosen any stuck bits, then turning them out onto a cooling rack to cool completely.
  7. While the cakes cool, you can make the frosting.
For the frosting:
  1. In a large bowl using a handheld electric mixer, or using a standmixer fitted with the paddle attachment, beat the cream cheese, butter, and peanut butter until smooth; about 2 minutes. Add honey and sea salt. Reduce speed to low and add in confectioners' sugar, one cup at a time. Beat on low speed until combined, then add in the heavy cream. Increase speed to medium-high and beat frosting until fluffy; about 3-4 minutes. Spread on cooled cake.
