Whenever I need a cake that feels extra special but is still easy to make, I always turn to my Best Sour Cream Banana Cake. It’s soft, moist, and full of sweet banana flavor with just the right touch of tang from the sour cream. This is the kind of cake that works for everything—holidays, birthdays, or even just a cozy family dessert. Trust me, once you take a bite, this cake will become a go-to favorite for any occasion.
INGREDIENTS YOU’LL NEED
- ½ cup Butter (softened to room temperature): I use real butter for richness and flavor—it gives the cake that soft, tender crumb.
- 1¼ cups Sugar: Just the right amount of sweetness to balance the bananas and sour cream.
- 2 Eggs (room temperature): My eggs add structure and help the cake rise while keeping it moist.
- 1 cup Sour Cream (room temperature): This is my secret to an ultra-moist cake with a little tangy depth.
- 1 teaspoon Vanilla Extract: A splash of vanilla warms up all the flavors in the cake.
- 2 cups Flour: I stick with all-purpose flour—it creates a sturdy but tender cake texture.
- 1 teaspoon Baking Soda: This gives the cake lift and works perfectly with the sour cream and bananas.
- ¼ teaspoon Salt: A little salt sharpens the sweetness and keeps the flavors balanced.
- 5 Ripe Bananas (mashed): The riper the better! They add natural sweetness, flavor, and moisture.
For the Cream Cheese Frosting:
- 16 oz Cream Cheese (softened to room temperature): I love how tangy cream cheese frosting balances the sweet cake.
- 1 cup Butter (2 sticks, softened): Butter makes the frosting rich and silky smooth.
- 2 teaspoons Vanilla Extract: A touch of vanilla makes the frosting taste extra homemade.
- 3 cups Powdered Sugar: Powdered sugar sweetens the frosting and makes it fluffy and spreadable.

Yes! I just scoop the batter into lined muffin tins and bake for about 18–22 minutes.

Sour cream is my favorite because it makes the cake extra moist, but I’ve swapped it with Greek yogurt and it still turns out delicious.
RECIPE SUBSTITUTIONS AND VARIATIONS
- Sometimes I swap the sour cream with plain Greek yogurt, and it still gives the cake that moist, tangy flavor.
- If I want a little crunch, I mix in chopped walnuts or pecans for extra texture.
- I’ve added chocolate chips before, and they make this cake taste like a bakery-style treat.
- When I want more flavor, I sprinkle in a little cinnamon or nutmeg to warm up the banana sweetness.
My Top 3 Recipe Tips for Success
- I always make sure my bananas are extra ripe because they give the best flavor and natural sweetness.
- I let all my ingredients (butter, eggs, sour cream, and cream cheese) come to room temperature so the batter mixes smoothly.
- I never overmix once I add the flour—this keeps the cake light and tender instead of dense.
WHAT DO YOU SERVE WITH SOUR CREAM BANANA CAKE?
I love serving this cake with a hot cup of coffee or tea because the flavors pair so well together. If I’m making it for a party, I’ll sometimes add fresh fruit on the side to balance the sweetness. For holidays or birthdays, a scoop of vanilla ice cream makes it extra special.
HOW TO STORE LEFTOVER OLD-FASHIONED BANANA CAKE?
I always store leftover banana cake in an airtight container in the fridge to keep it fresh, especially because of the cream cheese frosting. It usually stays moist and delicious for about 4–5 days. If I want to save it longer, I wrap individual slices and freeze them so I can thaw a piece whenever I’m craving something sweet.
CAN MOIST BANANA CAKE BE FROZEN FOR ANOTHER DAY?
When I freeze this cake, I like to wrap each slice tightly in plastic wrap and then place them in a freezer-safe bag or container. This way, they don’t dry out or get freezer burn. The cake freezes well for up to 2–3 months, and I just let a slice thaw in the fridge overnight or at room temperature before enjoying it again.
