Ingredients

• 3 medium ripe bananas
• 0.5 cup unsalted butter
• 1 cup granulated sugar
• 2 large eggs
• 2 teaspoons vanilla extract
• 0.5 cup sour cream
• 2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 0.5 teaspoon salt
• 0.75 cup brown sugar
• 1.5 teaspoons cinnamon
• 0.5 cup unsalted butter (for crumb topping)
• 0.75 cup all-purpose flour (for crumb topping)

Directions

Step 1

Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish and set aside.

Step 2

In a medium bowl, mash the ripe bananas until smooth and set aside.

Step 3

In a large mixing bowl, beat the unsalted butter and granulated sugar together until light and fluffy, about 2-3 minutes.

Step 4

Add the eggs, one at a time, mixing well after each addition. Stir in the vanilla extract and sour cream until combined.

Step 5

In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.

Step 6

Stir in the mashed bananas until fully incorporated. Pour the batter into the prepared baking dish and spread it evenly.

Step 7

To prepare the crumb topping, combine the brown sugar, cinnamon, flour, and diced cold butter in a small bowl. Use your fingers or a pastry cutter to mix until crumbly and evenly combined.

Step 8

Sprinkle the crumb topping evenly over the banana batter in the baking dish.

Step 9

Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center of the cake comes out clean.

Step 10

Allow the cake to cool in the pan for 15 minutes before slicing and serving. Serve warm or at room temperature. Optionally, dust with powdered sugar for extra sweetness.
