Banana Coffee Cake

Description
This express banana coffee cake features a tender, moist crumb enriched with sour cream and topped with a thick, buttery cinnamon streusel. It’s the perfect way to transform overripe bananas into a bakery-style treat in under an hour.
Ingredients
- 3 to 4 very ripe, spotty bananas
- 1/2 cup sour cream or Greek yogurt
- 1 cup light brown sugar, divided
- 2 teaspoons ground cinnamon, divided
- 1/2 cup unsalted butter, softened
- 1/2 cup granulated white sugar
- 2 large eggs
- 2 cups all-purpose flour, divided
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon vanilla extract
- 1/4 cup cold unsalted butter, cubed
Instructions
- Preheat your oven to 350°F (175°C) and lightly grease two 8×4-inch loaf pans.
- In a small bowl, mash the bananas thoroughly and stir in half of the brown sugar, the vanilla extract, and 1 teaspoon of cinnamon.
- In a large mixing bowl, beat the softened butter and white sugar until pale and fluffy, then mix in the eggs one at a time.
- Sift 1.5 cups of the flour, the baking soda, and the salt into the butter mixture; stir until barely combined and then fold in the sour cream.
- Gently pour the banana mixture into the batter and stir just until combined, being careful not to overmix.
- In a separate bowl, combine the remaining flour, remaining brown sugar, and remaining cinnamon; cut in the cold butter with a pastry cutter until coarse crumbs form.
- Divide the batter between the two pans, sprinkle the streusel topping evenly over both, and bake for 35-40 minutes until a toothpick comes out clean.
Notes
To keep the cake as moist as possible, ensure you do not overbake; start checking with a toothpick at the 35-minute mark. If you do not have a pastry cutter for the crumb topping, you can use two forks or your fingers to rub the butter into the dry ingredients until pea-sized clumps form.

The Express Pantry Lineup
Grab your mixing bowls because this ingredient list is wonderfully simple. We rely on everyday items that deliver maximum flavor and serious moisture without extra shopping trips.
- Bananas: You need 3-4 very ripe, spotty bananas for natural sweetness and a gooey texture.
- Sour Cream: This is our express shortcut for a tender, moist crumb. Greek yogurt works perfectly too!
- Brown Sugar & Cinnamon: Used in both the batter and the thick crumb topping for a warm, cozy flavor profile.
- Butter: Softened for the cake to mix quickly, and cold for the topping to create perfect coarse crumbs.
- Dry Staples: Just all-purpose flour, white sugar, baking soda, and a pinch of salt to hold everything together.
The Quick Baking Process
Step 1: Prep the Pans and Oven
Preheat your oven to 350°F (175°C). Lightly grease two 8×4-inch loaf pans so your cakes release effortlessly later.
Step 2: Mash the Banana Base
In a small bowl, thoroughly mash your bananas. Stir in the brown sugar, vanilla extract, and ground cinnamon until you have a dark, fragrant mixture.
Step 3: Cream the Butter
In a large mixing bowl, beat the softened butter and white sugar together until pale, light, and fluffy. Quickly mix in the eggs one at a time until just incorporated.
Step 4: Add Dry Ingredients and Sour Cream
Sift the flour, baking soda, and salt directly into your wet ingredients, stirring until barely combined. Gently fold in the sour cream for that instant moisture boost.
Step 5: Fold in the Bananas
Pour your mashed banana mixture into the batter. Stir everything together gently just until combined, being careful not to overmix so the crumb stays tender.
Step 6: Create the Express Crumb Topping
In a separate bowl, combine the cinnamon, flour, and brown sugar. Use a pastry cutter to cut in the cold butter until the mixture resembles coarse, pea-sized crumbs. Divide the batter between the two prepared pans and sprinkle this thick coating evenly over the top of both.
Step 7: Bake to Tender Perfection
Bake for 35-40 minutes. Test with a toothpick—it should come out clean with just a few moist crumbs attached. Let the cakes cool in the pans for 10 minutes before moving them to a wire rack.

For the most luscious results, never skip the sour cream. It acts as an instant tenderizer that mimics the effects of a long-soak recipe in minutes. If you want to read more about the science of baking with bananas, check out this excellent breakdown on coffee cake banana bread.
Always use bananas that are heavily speckled with brown or completely black. They mash faster and provide the concentrated sugars needed for a truly moist crumb. If you love this quick-baking style, you will also appreciate our classic express banana cake for another weeknight win.

You can easily customize this fast bake to suit your pantry. Toss a half-cup of mini chocolate chips into the batter for a gooey, molten twist. Chopped walnuts or pecans also make a fantastic addition to the streusel for extra crunch.
