Banana Cake

Don’t you love sheet cakes? They’re so easy to make and are perfect for large gatherings.

Take this banana sheet cake. Like our banana bread it has wonderful banana flavor, but with a little more sweetness, and a tangy cream cheese frosting. This banana cake is a perfect solution for those ripe bananas, and it’s a great crowd pleaser.

One batch of this banana cake easily makes 30 servings, convenient for potlucks and tailgates.

This banana cake with cream cheese frosting 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 this banana cake a strong two thumbs up and declares it “a keeper”. Enjoy!

Banana Sheet Cake Recipe

  • Prep time: 20 minutes
  • Cook time: 20 minutes
  • Yield: Makes 30 pieces

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.

Ingredients

Cake

  • 2 cups all purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon cinnamon
  • 1/2 teaspoon salt
  • 1/2 cup (1 stick) unsalted butter
  • 1 cup white granulated sugar
  • 1/2 cup brown sugar
  • 2 eggs
  • The scraped insides of one vanilla bean, or 1 teaspoon of vanilla extract
  • 1 cup of mashed ripe bananas (2 large or 3 medium bananas)
  • 1/2 cup full fat sour cream

Frosting

  • 6 ounces cream cheese, room temp
  • 4 Tbsp (1/4 cup) unsalted butter, room temp
  • 2 cups powdered sugar
  • 1 teaspoon vanilla extract
  • 1 teaspoon lemon juice

Method

1 Preheat the oven to 350°F (175°C) . In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt.

2 Beat together in a mixer the butter and sugars. Beat in the eggs one at a time. Mix in the vanilla and mashed bananas.

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

4 Spread batter evenly in a greased 10x15 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.

5 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.

    Made this gluten free for my wife the other day. 1 for 1 subbed King Arthur gluten free all purpose flour, added 1 and 1/4 tsp xanthan gum. (More xanthan gum than I would usually use, but that was the approximate ratio on a king arthur’s GF cake recipe). Used full fat Greek yogurt instead of sour cream as I was out. 13×9 pan for about 25 minutes.

    Turned out just a little dense, a little more banana bread-like than sheet cake, but it was quite good, wife loved it, i even thought it was good and I’m generally not a fan of gluten free desserts. This or a variation of this will get in the rotation for GF desserts.

    Sounds delicious but what the heck am I going to do with the other 2 ounces of cream cheese?????

  • Heather White

    I made one of these banana cakes for myself and one for my neighbors kids. They absolutely loved it and I did as well. The lemon added to the frosting really sets it apart from the standard cream cheese frosting. I made another two cakes after another round of bananas were ready to go. I did half with chocolate chips and chocolate cream cheese frosting and the other half this recipe’s cream cheese frosting. I really can’t decide which side was better! Thanks for this delicious, moist, banana cake recipe!

    I finally made your banana cake, and it was delicious! With the exception of adding a 1/2 tsp of banana extract and a handful walnuts, I made it exactly as written. It turned out beautiful. It even looked like the one in your picture. It was so good that I am making another one this weekend. Thanks for the recipe, Elise! :)
