Banana Layer Cake with Cream Cheese Frosting

Preparation

1. Step 1

   Preheat oven to 350°F. Lightly butter three 8-inch-diameter cake pans with 2-inch-high sides; dust pans with flour. Combine cake flour, baking soda, baking powder and 1/2 teaspoon salt in medium bowl. Mix mashed bananas, buttermilk and 1 teaspoon vanilla in another medium bowl. Using electric mixer, beat 1/2 cup butter and sugar in large bowl until blended. Add eggs 1 at a time, beating to blend after each addition. Add dry ingredients alternately with banana mixture in 3 additions, beginning and ending with dry ingredients and beating just until blended after each addition. Divide batter equally among prepared pans.

   Step 2

   Bake cakes until tops are just beginning to color and tester inserted into center comes out with a few crumbs attached, about 20 minutes. Cool cakes in pans on racks 10 minutes. Using small knife, cut around cakes to loosen; turn cakes out onto racks and cool completely.

   Step 3

   Beat cream cheese and remaining 1 cup butter in large bowl until light and fluffy. Beat in remaining 1 tablespoon vanilla and pinch of salt. Gradually beat in powdered sugar. Cover and refrigerate frosting until firm enough to spread, about 15 minutes.

   Step 4

   Place 1 cake layer on platter. Spread 1/2 cup frosting over top. Place half of sliced bananas evenly over frosting, leaving 1/4-inch border at edge. Place second cake layer on work surface. Spread 1/4 cup frosting over top. Place cake layer, frosting side down, atop bananas. Spread 1/2 cup frosting over top. Place remaining half of sliced bananas evenly over frosting, leaving 1/4-inch border at edge. Place third cake layer on work surface. Spread 1/4 cup frosting over top. Place cake layer, frosting side down, atop bananas. Spread remaining frosting over sides and top of cake. (Can be made 1 day ahead. Cover and chill. Let stand 1 hour at room temperature before serving.)
