Banana Sheet Cake
One thing I ALWAYS have on hand? Bananas! And more often than not, I have an overripe banana (or 10) that’s just begging to become dessert! My current obsession? Banana Cake! It’s moist, dense, and perfectly sweet. And since it’s baked in a sheet pan, it’s MUCH easier than a layer cake.
This cake stays moist for days! And travels great. So it’s my go-to cake for picnics, parties, potlucks, etc! The cream cheese frosting is super basic, but you can certainly spruce it up by adding in a dash of cinnamon or a handful of chopped nuts. It’s up to you!
Banana Cake Ingredients
- all-purpose flour: be sure not to pack your flour into the measuring cup! I suggest spooning loosely into the measuring cup and then leveling the cup off with the flat edge of a knife.
- baking soda and salt: make sure your baking soda is fresh! and don’t skip the salt. just a pinch enhances the other flavors!
- ground cinnamon: I find one teaspoon is the perfect amount! If you prefer a richly spiced banana cake, feel free to increase by a half teaspoon.
- ground nutmeg: just a pinch adds a nice subtle spice!
- mashed bananas: be sure your bananas are ripe!
- dark brown sugar: pack your brown sugar into the measuring cup! light brown sugar will work in a pinch.
- granulated sugar: any variety will do!
- sour cream: full-fat and at room temperature!
- vegetable oil: but canola oil or melted coconut oil will do!
- large eggs: you’ll need 3 large eggs plus 1 egg yolk. be sure to bring your eggs to room temperature!
- cream cheese: full-fat cream cheese is the base of our cream cheese frosting. be sure it’s at room temperature (aka very soft) before making the frosting.
- unsalted butter: just a few tablespoons make the frosting rich and creamy!
- powdered sugar: be sure to add a 1/2 cups at a time, so it doesn’t fly out of the mixing bowl!
- pecans: I LOVE adding toasted pecans to this banana cake! walnuts or even pistachios would be equally delicious! of course if you’re allergic to nuts, simply omit! sliced bananas make an equally nice garnish.
How to make Banana Cake
- Preheat the oven. Spray a 9×13 inch baking pan with nonstick baking spray and set it aside.
- In a large bowl, whisk together the flour, baking soda, salt, cinnamon. and nutmeg. Set aside.
- In a separate large bowl, whisk together the mashed bananas, sugars, sour cream, and oil. Whisk in eggs and yolk, one at a time. Then add the dry ingredients to the wet, mixing only until combined. Don’t overmix!
- Pour the banana cake batter into the greased sheet pan and smooth the top. Bake for about 35 minutes, or until a tester inserted in the center of the cake comes out clean, or with just a few crumbs attached. The bake time will vary depending on your oven, so it may take an extra 5 minutes or so.
- Place the cake pan on a wire cooling rack. Cool completely!!! This takes over an hour for me. But have patience! Because if you frost even a semi-warm cake it’ll be a disaster.
- Once the cake has completely cooled, spread the frosting on top and sprinkle with pecans, if using. Slice and serve!
