Ingredients
- 2 cups all-purpose flour
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1 teaspoon ground cinnamon
- 1 cup mashed ripe bananas
- 1/2 cup granulated sugar
- 1/2 cup packed brown sugar
- 1/2 cup unsalted butter softened
- 2 large eggs
- 1 teaspoon vanilla extract
- 1/2 cup buttermilk
- 1/2 cup all-purpose flour
- 1/2 cup packed brown sugar
- 1 teaspoon ground cinnamon
- 4 tablespoons unsalted butter cold
Instructions
- Preheat the oven to 350°F and grease a 9-inch square baking pan or line it with parchment paper.
- In a medium bowl, whisk together 2 cups flour, baking powder, baking soda, salt, and 1 teaspoon cinnamon; set aside.
- In another bowl, combine 1/2 cup flour, 1/2 cup brown sugar, 1 teaspoon cinnamon, and cold butter; use a pastry cutter or fork to form coarse crumbs and set streusel aside.
- In a large bowl, cream 1/2 cup softened butter with granulated sugar and 1/2 cup brown sugar until light and fluffy.
- Beat in eggs one at a time, then stir in vanilla and mashed bananas until just combined.
- Alternately add the dry flour mixture and buttermilk, beginning and ending with the flour mixture, mixing until just incorporated.
- Spread half of the batter into the prepared pan, sprinkle half of the streusel over the batter, then top with the remaining batter and streusel.
- Bake for 40 to 45 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the coffee cake to cool in the pan on a wire rack for at least 15 minutes before slicing and serving.
Notes
- Cake can be stored in an airtight container at room temperature for up to 3 days
- Substitute sour milk for buttermilk by adding a teaspoon of vinegar to regular milk and letting it sit for 5 minutes
- Use very ripe bananas for maximum sweetness and moisture
- Serve warm or at room temperature with a cup of coffee or tea
