This Banana Coffee Cake is the perfect way to use them up, resulting in a tender, moist crumb topped with a crunchy, buttery cinnamon streusel that pairs perfectly with a hot cup of coffee.
Why This Banana Coffee Cake Works
This recipe relies on the natural sweetness and moisture of very ripe bananas to create a rich base. By using sour cream in the batter, the cake stays soft and dense without becoming heavy.
The contrast between the soft cake and the crumbly cinnamon topping makes every bite satisfying. It is a straightforward bake that comes together quickly, making it a reliable choice for weekend mornings or when you need a simple treat to share.
Ingredient Notes
Bananas: Use the ripest bananas you have. The more brown spots on the peel, the sweeter and more flavorful your cake will be.
Butter: Ensure your butter for the cake batter is softened to room temperature so it creams easily with the sugar. Keep the butter for the topping cold, as this creates those distinct, buttery crumbs.
Sour Cream: This adds a subtle tang and helps keep the cake moist for days.

Preheat your oven to 350 degrees F and lightly grease a 9×13 inch baking dish.
In a large bowl, beat the softened butter and sugar together until the mixture is smooth and creamy.
Add the eggs, vanilla extract, and sour cream to the butter mixture, whisking until well combined.
Fold in the mashed bananas until incorporated.
In a separate bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon.
Gently stir the dry ingredients into the banana mixture until just combined, being careful not to overmix.
Spread the batter evenly into your prepared baking dish.
To make the topping, combine the flour, granulated sugar, brown sugar, and cinnamon in a medium bowl.
Cut the cold, cubed butter into the dry mixture using a fork or your fingers until the topping looks like coarse crumbs.
Scatter the crumb mixture evenly over the top of the cake batter.
Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan before slicing and serving.
