Are you a banana bread enthusiast who always wants more, more, MORE?! This easy banana cake recipe is ready to satisfy your very specific needs. The crumb is sweeter and more tender than that stalwart breakfast bread. The bananas are more present, being both mashed into the batter and sliced into disks and sandwiched between the two cake layers. Plus, there’s frosting! Banana bread, who?

You’ll need fruit at two stages of ripeness for this super-moist banana cake: For the batter, use overripe bananas—black speckles are a good thing! These have a higher ratio of sugars to starches than firm bananas and mash easily with a fork. Meanwhile, for the layer of slices, pick bananas that are ripe but still sturdy and unblemished.

This recipe doesn’t call for nuts, but if you wanted to toss in a handful (or more) of well-toasted chopped walnuts or pecans, they wouldn’t be unwelcome. Similarly, the frosting here is a souped-up American buttercream, made billowy with a large pour of heavy cream. But if you dream of cream cheese frosting all day, every day, go for it.

Whichever icing you choose, follow former BA staffer and cookbook author Claire Saffitz’s advice: Don’t skip the crumb coat (think of it as the primer you put on the walls before you paint). Follow her step-by-step tutorial here. And when it comes to achieving those artful swoops and swirls on the top of a layer cake, all it takes is a spoon and some practice.

Recipe information

  • Total Time

    1 hour 20 minutes plus cooling

  • Yield

    16 Servings

Ingredients

Cake

1½ cups (3 sticks) unsalted butter plus more for pans, room temperature
3¾ cups all-purpose flour
1½ teaspoons baking soda
1¼ teaspoons kosher salt
2¼ cups sugar
6 large eggs
3 cups coarsely mashed very ripe bananas (about 6 large)
¾ cup sour cream

Frosting

1 cup (2 sticks) unsalted butter, room temperature
4 cups powdered sugar
½ cup heavy cream
1 teaspoon vanilla extract
½ teaspoon kosher salt
2 ripe but not mushy bananas, cut crosswise into ⅛-inch slices

Preparation

  1. Cake

    Step 1

    Preheat oven to 325°. Butter two 8"-diameter round cake pans with sides 2" high. Line bottoms of pans with parchment paper rounds. Whisk flour, baking soda, and salt in a large bowl. Using an electric mixer, beat 1½ cups butter and sugar in another large bowl until light and fluffy, 2–3 minutes. Add eggs one at a time, beating to blend between additions. With mixer on low, gradually beat in flour mixture, scraping sides of bowl. Mix in bananas, then sour cream. Divide batter between prepared pans.

    Step 2

    Bake cakes until a tester inserted into the center comes out clean, 50–55 minutes. Let cool for 20 minutes in pans on wire racks.

    Step 3

    Invert cakes onto wire racks; let cool completely. Remove parchment. Using a serrated knife, trim off rounded tops.

  2. Frosting

    Step 4

    Using an electric mixer, beat first 5 ingredients in a large bowl until light and fluffy, 6–7 minutes.

    Step 5

    Place 1 cake on a plate. Spread 1 cup frosting over. Arrange banana slices on top. Top with second cake. Spread a thin layer of frosting over top and sides of cake; chill for 30 minutes. Spread remaining frosting over top and sides of cakes.
