What Ingredients Do You Need for Banana Cake with Buttercream Frosting?
The beauty of this recipe is that it uses ingredients you probably already have in your kitchen. Here’s what you’ll need:
- For the cake: 3 ripe bananas, 2 cups all-purpose flour, 1 1/2 cups sugar, 1/2 cup butter, 2 eggs, 1 tsp vanilla extract, 1 tsp baking soda, 1/2 cup sour cream, and 1/2 tsp salt
- For the frosting: 2 cups powdered sugar, 1/2 cup butter, 2 tbsp heavy cream, and 1/2 tsp vanilla
Why This Recipe Works
The secret to a truly moist banana cake is using ripe bananas—and I mean really ripe. Those brown-spotted bananas that you might normally toss out? They’re exactly what you need. The riper the banana, the sweeter and more flavorful your cake will be. The sour cream adds moisture and a subtle tang that balances the sweetness perfectly. And the baking soda? It reacts with the acidic sour cream to create a tender crumb that just melts in your mouth.
The frosting is where this cake really shines. A simple buttercream made with real butter and a touch of heavy cream creates a frosting that’s creamy, smooth, and absolutely delicious. It’s not too sweet, and it complements the banana flavor beautifully.
How Do You Make Banana Cake with Buttercream Frosting?
This recipe is straightforward and doesn’t require any special skills. Follow these steps and you’ll have a beautiful, delicious cake:
- Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
- In a medium bowl, whisk together the flour, baking soda, and salt.
- In a large bowl, cream the butter and sugar together until light and fluffy. This should take about 2-3 minutes with an electric mixer.
- Add the eggs one at a time, beating well after each addition. Then stir in the vanilla extract.
- Add the mashed bananas and sour cream to the wet ingredients, mixing until just combined.
- Gradually add the dry ingredients to the wet ingredients, stirring just until combined. Don’t overmix—a few lumps are okay.
- Divide the batter evenly between the two prepared pans and smooth the tops.
- Bake for 30-35 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then turn them out onto wire racks to cool completely.
- For the frosting: Beat the butter until creamy, then gradually add the powdered sugar, beating well after each addition.
- Add the heavy cream, vanilla, and a pinch of salt. Beat until light and fluffy.
- Once the cakes are completely cool, place one layer on a cake plate and spread frosting on top. Add the second layer and frost the top and sides.
Pro Tips for Success
Use really ripe bananas: The spottier, the better. They’ll give you the most flavor and moisture.
Don’t overmix the batter: Overmixing develops gluten, which can make your cake tough. Mix just until the ingredients are combined.
Let the cakes cool completely: Before frosting, make sure your cakes are completely cool. Frosting a warm cake will cause it to melt and slide off.
Room temperature ingredients: For the best results, use room temperature butter and eggs. They’ll incorporate more smoothly into the batter.
Make it ahead: You can bake the cakes a day ahead and store them wrapped in plastic wrap. Frost just before serving for the best presentation.
Variations and Substitutions
Add nuts: Fold 1 cup of chopped walnuts or pecans into the batter for added texture and flavor.
Cream cheese frosting: For a tangier frosting, substitute 4 oz of cream cheese for some of the butter.
Make it chocolate: Add 1/4 cup of cocoa powder to the dry ingredients for a chocolate banana cake.
Single layer cake: Use one 9×13 inch pan instead of two round pans for a simpler presentation.
Storage and Make-Ahead Tips
Room temperature: Store the frosted cake under a cake dome or covered with plastic wrap at room temperature for up to 3 days.
Refrigerator: For longer storage, keep the cake in the refrigerator for up to 5 days. Let it come to room temperature before serving for the best flavor.
Freezer: You can freeze unfrosted cake layers for up to 3 months. Wrap them well in plastic wrap and aluminum foil. Thaw at room temperature before frosting.
Frequently Asked Questions
Can I use frozen bananas?
Yes! Thaw them completely and drain any excess liquid before mashing. They work just as well as fresh bananas.
What if I don’t have sour cream?
You can substitute Greek yogurt or even buttermilk in equal amounts. The texture might be slightly different, but it will still be delicious.

How do I know when the cake is done?
Insert a toothpick into the center. It should come out clean or with just a few moist crumbs. If it comes out wet with batter, bake a few more minutes.
