Best Banana Sheet Cake Recipe

If you're looking for a big cake with a delicious blend of flavors it's time to do a happy dance because you are at the right place. This is the best banana sheet cake recipe I have ever tasted.

It's easy to make and can be topped with brown butter frosting or a rich cream cheese frosting and because it's a sheet cake, it's perfect for large gatherings.

This easy banana cake is the perfect recipe to make any time you have some extra ripe bananas in the house and don't feel like making the usual, albeit delicious, banana bread (this is my favorite recipe!). It's packed with just the right amount of banana flavor and may be the moistest cake you've ever made.

📖 Variations

  • I've given the recipe for browned butter frosting and cream cheese icing but no matter which kind of frosting you use, this cake is delicious. p.s. You could also use a caramel frosting for an additional layer of flavor.
  • Is chocolate your thing? If so, you can add 1 cup of chocolate chips as the last step using a rubber spatula to gently fold them into the batter before pouring it into the jelly roll pan.
  • Top with sliced bananas and nuts if desired.

Hand Mixer or Electric Mixer - I love my KitchenAid cordless hand mixer. It's very convenient and stays charged throughout my mixing process.

Measuring Cups and Spoons, Spatula, and Bowls - the basics!


Cover cake with foil or plastic wrap and store in the refrigerator. To keep the covering from sticking to the icing, stick toothpicks at regular intervals and then cover with foil or plastic wrap. It's an old trick but it works great!

  1. In the supplies it says you need a half sheet pan but then it says to use a 10 x 15 pan which is not the same size as the link you provide to the pan.

      Hello Jen,
      Thank you for letting me know about the discrepancy. I updated the post to reflect the correct pan size which is 10 x 15.
