This recipe comes from my friend Kelsey Fischer and her mom Janeen. It's is a family favorite of theirs.

I've made a few slight adjustments to the recipe by adding some lemon juice to the cream cheese frosting to give it more tang, and then added some vanilla to the banana cake batter.

My dad gives the cake a strong two thumbs up and declares it "a keeper". Enjoy!

Here's a tip, leave the cream cheese and butter for the frosting out while you make the banana cake, that way they will be softened by the time the cake is cooled and ready to frost. This banana cake is on the sweet side (it is a cake after all).

If you are trying to cut sugars, you may want to experiment dropping the sugar in the cake mixture by a half cup and cutting the amount of frosting in half.



  • 2 cups all-purpose flour

  • 1 teaspoon baking soda

  • 1 teaspoon cinnamon

  • 1/2 teaspoon kosher salt

  • 1/2 cup (1 stick) unsalted butter, room temperature

  • 1 cup white granulated sugar

  • 1/2 cup brown sugar

  • 2 large eggs

  • 1 vanilla bean (scraped clean, outside discarded), or 1 teaspoon vanilla extract

  • 1 cup mashed ripe bananas (2 large or 3 medium bananas)

  • 1/2 cup full fat sour cream


  • 6 ounces cream cheese, room temperature

  • 4 tablespoons (1/4 cupunsalted butter, room temperature

  • 2 cups powdered sugar

  • 1 teaspoon vanilla extract

  • 1 teaspoon lemon juice


  1. Preheat the oven to 350°F (175°C) .

    Place the oven rack in the middle of the oven.

  2. Whisk together the dry ingredients:

    In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt.

  3. Beat together the butter, sugars, and eggs:

    In a mixer, beat together butter and the sugars. Add eggs one at a time and beat.

  4. Mix in the vanilla and bananas:

    Add vanilla and bananas and beat until just mixed in.

  5. Mix in the flour and sour cream:

    Mix in half of the flour mixture, then the sour cream, then the other half of the flour mixture.

  6. Spread the batter in baking pan:

    Spread batter evenly in a greased 10- x15-inch baking pan. Bake at 350°F (175°C) for 20 minutes, or until nicely browned and the surface bounces back when you press it with your finger. Cool completely before frosting.

  7. Make the frosting and frost the cake:

    To make the frosting, mix all of the ingredients together with an electric mixer. If too stiff to spread, add a teaspoon or two of water.

    Spread the frosting evenly over the cake and slice to serve.
