How To Make Banana Crumb Coffee Cake with Streusel Topping
Pull out your mixing bowls and let’s assemble this delightful coffee cake. You’ll start by preparing both the dry mix and the buttery streusel, then whip up the banana-infused batter, layer everything in the pan, and bake until golden and fragrant. Follow each detailed step below to achieve the perfect balance of moist cake and crunchy topping.
1. Preheat the oven to 350°F and grease a 9-inch square baking pan or line it with parchment paper to ensure easy removal.
2. In a medium bowl, whisk together 2 cups all-purpose flour, 1 teaspoon baking powder, 1/2 teaspoon baking soda, 1/2 teaspoon salt, and 1 teaspoon ground cinnamon until evenly combined; set this dry mixture aside.
3. In another bowl, combine 1/2 cup all-purpose flour, 1/2 cup packed brown sugar, 1 teaspoon ground cinnamon, and 4 tablespoons cold unsalted butter; use a pastry cutter or fork to cut the butter into the dry ingredients until pea-sized crumbs form, then set your streusel aside.
4. In a large bowl, use an electric mixer to cream 1/2 cup softened unsalted butter with 1/2 cup granulated sugar and 1/2 cup packed brown sugar until light and fluffy, about 3 minutes.
5. Beat in the 2 large eggs one at a time, mixing well after each addition; then stir in 1 teaspoon vanilla extract and 1 cup mashed ripe bananas until just combined.
6. Alternate adding the reserved dry flour mixture and 1/2 cup buttermilk to the banana batter—begin and end with the flour—mixing gently until just incorporated. Avoid overmixing to keep your cake tender.
7. Spread half of the batter into the prepared pan, then sprinkle half of the streusel mixture evenly over the top. Repeat with the remaining batter and finish with the last of the streusel.
8. Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
9. Allow the coffee cake to cool in the pan on a wire rack for at least 15 minutes before slicing and serving, so the crumb sets perfectly.
