This is the kind of recipe you’ll make once and then save forever.
The Secret to an Ultra-Moist Banana Cake
The secret ingredient in this banana cake is full-fat sour cream. Sour cream adds richness and moisture without making the cake dense. It also balances the sweetness of the bananas and sugar, giving the cake a soft crumb that stays tender even after refrigeration.
If you’ve ever had banana cake turn out dry, crumbly, or heavy — sour cream is the fix.
Ingredients You’ll Need
Banana Cake Ingredients
- ½ cup (1 stick) salted butter, softened
- 1½ cups granulated sugar
- 2 large eggs
- 1 cup full-fat sour cream
- 1 teaspoon vanilla extract
- 2 cups all-purpose flour
- 1 teaspoon baking soda
- ¼ teaspoon salt
- 1 cup mashed ripe bananas (about 3–4 bananas)
Cream Cheese Frosting Ingredients
- ½ cup (1 stick) butter, softened
- 8 oz full-fat cream cheese, softened
- 1 teaspoon vanilla extract
- 3 cups powdered sugar
- 2 tablespoons heavy whipping cream
How Ripe Should Bananas Be for Banana Cake?
For the best banana flavor, your bananas should be:
- Heavily speckled
- Brown or mostly brown
- Soft to the touch
The darker the banana, the sweeter and more flavorful your cake will be. Fresh yellow bananas can be used in a pinch, but the flavor won’t be nearly as rich.
How to Make Easy Banana Cake (Step-by-Step)
Step 1: Preheat & Prepare
Preheat your oven to 350°F. Spray a 9×13 baking dish with nonstick cooking spray and set aside.
Step 2: Cream Butter & Sugar
In a large bowl, beat the butter and sugar together until light and fluffy. It may look crumbly at first — keep mixing and it will smooth out.
Step 3: Add Wet Ingredients
Add the eggs, sour cream, and vanilla extract. Mix until smooth and creamy.
Step 4: Add Dry Ingredients
Add the flour, baking soda, and salt. Mix on low speed just until combined. Do not overmix.
Step 5: Fold in Bananas
Gently stir in the mashed bananas until evenly distributed.
Step 6: Bake
Spread the batter evenly into the prepared pan. Bake for 25–35 minutes, or until a toothpick inserted in the center comes out with moist crumbs.
Let the cake cool completely before frosting.
How to Make the Best Cream Cheese Frosting
In a large bowl, beat the butter and cream cheese until smooth. Add the vanilla extract, powdered sugar, and heavy whipping cream. Beat until thick, fluffy, and spreadable.
Pro tip: Heavy cream creates a richer, fluffier frosting than milk. If substituting milk, use less and add gradually.
Frosting & Garnish Ideas
Once cooled, frost the cake generously and garnish with:
- Fresh banana slices
- Chopped walnuts or pecans
- A light dusting of cinnamon
Slice into squares and serve.
Helpful Tips for Perfect Banana Cake
- Always use full-fat sour cream and cream cheese
- Let the cake cool completely before frosting
- For clean slices, chill the cake briefly before cutting
- Store leftovers covered in the refrigerator
Can You Make Banana Cake Ahead of Time?
Yes — and it’s even better the next day.
Bake the cake, let it cool completely, then cover tightly and leave it at room temperature overnight. Frost a few hours before serving and refrigerate until ready. The flavor deepens and the texture improves.
Should Banana Cake Be Served Cold or Room Temperature?
Both are delicious.
- Cold: firmer frosting, richer texture
- Room temperature: softer cake, stronger banana flavor
Try both and see which you prefer.
