Ingredient Notes
Use Ripe Bananas
Very ripe bananas with brown spots work best for this recipe.
They are sweeter, softer, and add plenty of moisture and natural banana flavor to the cake.
Sour Cream
Sour cream helps create a soft and moist cake texture.
You can use plain Greek yogurt as an alternative.
Brown Sugar
Brown sugar gives the crumb topping a warm caramel-like flavor.
How to Make Banana Coffee Cake
1. Preheat the Oven
Preheat your oven to 350°F.
Grease an 8×8-inch baking pan or line it with parchment paper.
2. Prepare the Cinnamon Crumb Topping
In a medium bowl, combine:
- Flour
- Brown sugar
- Cinnamon
Pour in the melted butter.
Use a fork to mix everything together until large crumbs form.
Set aside.
3. Mash the Bananas

Place the ripe bananas in a bowl.
Mash them with a fork until mostly smooth.
A few small pieces are completely fine.
4. Cream the Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar together until light and creamy.
5. Add the Eggs and Vanilla
Add the eggs one at a time.
Mix well after each addition.
Add the vanilla extract and mix again.
6. Add the Banana and Sour Cream
Add the mashed bananas and sour cream.
Mix until everything is well combined.
7. Mix the Dry Ingredients

In a separate bowl, whisk together:
- Flour
- Baking powder
- Baking soda
- Cinnamon
- Salt
8. Make the Cake Batter
Gradually add the dry ingredients to the banana mixture.
Mix gently until just combined.
Do not overmix.
The batter should be thick and smooth.
9. Add the Batter to the Pan

Spread the banana cake batter evenly into the prepared baking pan.
10. Add the Crumb Topping
Sprinkle the cinnamon crumb topping evenly over the batter.
Make sure the crumbs are spread across the entire surface.
11. Bake
Bake for approximately 35–40 minutes.
The cake is ready when a toothpick inserted into the center comes out clean or with a few moist crumbs.
12. Cool and Serve

Allow the banana coffee cake to cool slightly before slicing.
Serve warm or at room temperature.
Tips for the Best Banana Coffee Cake
Use Very Ripe Bananas
Ripe bananas create a sweeter and more flavorful cake.
Avoid using firm green bananas.
Don’t Overmix the Batter
Mix the batter only until the dry ingredients are incorporated.
Overmixing can make the cake dense.
Make Sure the Butter Is Softened
Softened butter blends smoothly with the sugar and helps create a tender cake.
Check the Cake Early
Start checking the cake around the 35-minute mark because oven temperatures can vary.

Fold 1/2 cup chocolate chips into the banana cake batter before baking.
Banana Nut Coffee Cake
Add 1/2 cup chopped walnuts or pecans to the batter or crumb topping.
Cream Cheese Banana Coffee Cake

Maple Banana Coffee Cake
