author: Marlynn Schotland, Urban Bliss Life source:


  • 1/2 cup cold butter (8 tablespoons), cut into small cubes [crumb]

  • greater than 1 cup all purpose flour [crumb]

  • 1 cup packed light brown sugar [crumb]

  • 1/2 cup granulated sugar [crumb]

  • 1 tsp ground cinnamon [crumb]

  • 2 cups all-purpose flour [cake]

  • 3 tsp baking powder [cake]

  • 1 tsp ground cinnamon [cake]

  • 1 tsp salt [cake]

  • 3 ripe bananas, peeled and mashed [cake]

  • 1/2 cup butter, softened to room temperature [cake]

  • 1 cup granulated sugar [cake]

  • 2 large eggs [cake]

  • 1 tsp vanilla [cake]

  • 1 cup milk [cake]

  • 1 cup powdered sugar [glaze]

  • 1-2 tbsp almond milk [glaze]


  • Preheat oven to 350º F. Grease a 9” x 13” baking dish with butter or cooking spray; set aside.

  • In a large bowl, use your hands or two forks to crumble together the cold butter cubes, flour, sugars, and cinnamon until the mixture resembles a crumbly topping. Set aside the crumb mixture. 

  • In a large bowl, whisk together flour, baking powder, cinnamon, and salt. Set aside.

  • In a stand mixer, mix softened butter on medium until creamy, about 2 minutes. Add the sugar and mix for another minute, until well incorporated. Then add the eggs, vanilla, and mashed bananas, and mix just until ingredients are incorporated (do not overmix!) 

  • Turn the mixer down to low, and alternate mixing in milk and flour until all ingredients are combined.

  • Pour half of the cake mixture into the prepared baking dish. Top with 1/3 - 1/4 of the crumb mixture. Then pour the remaining cake mixture on top of that layer and finally, top evenly with the remaining crumb topping.

  • Bake at 350º for 50-55 minutes, until a toothpick comes out clean. 

  • {“To make the optional glaze”=>”In a small bowl, whisk together the powdered sugar and 1 tablespoon of milk. Add more milk as needed until you get the glaze consistency you prefer. Set aside.”}

  • Cool at room temperature for 5-10 minutes before drizzling the glaze over the top, slicing, and serving.
