For the Cake:
1 cup (2 sticks) unsalted butter, at room temperature
1 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1 teaspoon baking powder
1 teaspoon salt
1 cup buttermilk (or substitute with yogurt or sour cream)
3 ripe bananas, mashed
For the Cinnamon Filling:
1/2 cup packed light brown sugar
1 tablespoon ground cinnamon
1 teaspoon cocoa powder (optional, for color)
For the Crumb Topping:
1 cup all-purpose flour
1 cup packed light brown sugar
1 teaspoon ground cinnamon
1/2 cup unsalted butter, melted
Preheat your oven to 350°F (175°C). Grease a 9×12-inch baking pan and set aside.
In a small bowl, mix together the brown sugar, cinnamon, and cocoa powder for the filling. Set aside.
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt for the cake. Set aside.
In a large mixing bowl, cream together the butter and granulated sugar until light and fluffy. Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
Add the flour mixture to the wet ingredients in three additions, alternating with the buttermilk. Begin and end with the flour mixture. Mix until just combined.
Fold in the mashed bananas until evenly incorporated.
Pour half of the batter into the prepared pan and spread it into an even layer. Sprinkle the cinnamon filling evenly over the batter.
Top with the remaining batter, spreading it evenly over the filling.
In a separate bowl, combine the flour, brown sugar, and cinnamon for the crumb topping. Stir in the melted butter until large crumbs form. Sprinkle the crumb topping evenly over the cake batter.
Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean.
Allow the cake to cool in the pan on a wire rack before serving.
