Sour Cream Banana Cake
This moist, tender Sour Cream Banana Cake with cream cheese frosting is destined to be your new go-to recipe for ripe bananas! I was served for dessert on an antebellum plantation along the Ohio River. We all licked our plates clean! This scrumptious dessert got rave reviews, so naturally, I had to bake it up at home!
Who even knew there were plantations in Indiana?! We were lucky enough to spend a lovely autumn afternoon on the grounds, which included a spectacular Southern lunch. Lucky for me, the caterer was generous with her recipes. It was nearly impossible not to eat a second slice of this tender, Easy Banana Cake.
Why You Must Make
- The only difficult part of making this banana cake recipe was waiting for my bananas to ripen.
- If you always make banana bread with your overripe bananas, this is a tasty alternative.
- If you don’t have ripe bananas, you can easily make your yellow bananas perfect for banana bread or cake, by simply roasting them in the oven. More on that below.
- Plus, if you love cream cheese frosting as much as I do, this cake is the perfect excuse to make a batch.
This banana cake with sour cream recipe is pretty straightforward. You’ll need a 10 x 15 jellyroll pan and I also love my offset spatula for smoothing out the batter and frosting, but the latter is optional. (affiliate links)
- PRO-Tip: The ideal bananas for this cake have gone beyond yellow and have skins with brown speckles and spots, but not completely brown and mushy. The speckled bananas have more sugar than a solid yellow banana and give more banana flavor to your baked goods.
- If your bananas are still yellow, roasting them can bring out the necessary sugars along with softening the fruit.
- PRO Tip: How to ripen bananas in the oven is an easy hack. With the skins on, place the bananas on a parchment-lined baking sheet. Let them roast in a 300º oven for 30-40 minutes, flipping at the halfway point, until the skins are dark.
- Cool and use in your recipe as you would any ripe banana.
- Feel free to add some roasted chopped walnuts into the batter or top the frosting with chopped nuts or coconut to jazz up this banana cake.
- If you use a pan that’s smaller than 15 x 10-inches, you will need to bake this cake longer.
- PRO-Tip: If you find yourself with overripe bananas, peel them, then toss them into a freezer-safe Ziploc bag, remove any excess air and store them in the freezer until you want to make banana cake, bread or muffins. Defrost, then use as directed.
- PRO-Tip: Frozen bananas are good indefinitely if frozen properly!
How to Make
- Preheat the oven and prep the baking pan.
- With a hand mixer, beat the wet ingredients except for the bananas, starting with the butter and sugar.
- Stir in the dry ingredients, then the bananas. PRO-Tip: Do not use the mixer as you don’t want to over-activate the gluten making a tougher cake and you don’t want to incorporate a lot of air into the batter.
- Add batter to the pan and smooth the top with an offset spatula.
- Bake until a toothpick inserted in the center comes out clean. PRO-Tip: Be careful not to overbake or the cake will be dry.
- While the cake is cooling to room temperature, make the frosting, then ice the cake. PRO-Tip: Sifting the powdered sugar will make a smoother frosting.
- PRO-Tip: Store the cake in the refrigerator since it has a cream cheese frosting.
- PRO-Tip: To serve, let the cake sit out at room temperature for about 30 minutes. The frosting will be creamier and the cake softer and more tender.
Frequently Asked Questions
Banana Cake is typically mixed like a butter cake, creaming the butter and sugar, then adding in the eggs, etc. Banana Bread is made like other quick bread, and instead of being soft and cakey, it’s firm and dense. This makes banana bread easy to slice and toast.
Adding ingredients like sour cream provides extra fat and adds moisture to the cake. Also, not overbaking will also ensure the cake does not lose too much moisture in the oven.
Besides adding moisture due to the fat content in sour cream, the acidic nature of sour cream breaks down the gluten bonds in the flour, making a tender cake.
