A soft, tender, easy-to-make banana bread crumb cake, heavy on the crumbs and topped with a to-die-for peanut butter glaze!



Crumb Filling and topping:

  • 1 cup cold butter, cubed
  • 2 cups light brown sugar
  • 2 cups all purpose flour

For the Coffee Cake:

  • 2 cups all purpose flour
  • 3 teaspoon baking powder
  • 1 teaspoon cinnamon
  • 1 teaspoon salt
  • 3 ripe bananas, mashed
  • 1/2 cup unsalted butter, room temperature
  • 2 cups granulated sugar
  • 2 large eggs, room temperature
  • 1 teaspoon vanilla
  • 1 cup whole milk

For the Peanut Butter Glaze:

  • 2/3 cup powdered sugar
  • 2 tablespoon whole milk
  • 2 tablespoon creamy peanut butter


  1. To make the filling/topping: Place bow sugar and flour in the bowl of a food processor fitted with a metal blade. Process with six 1-second pulses. Remove cover of food processor and sprinkle the butter evenly over the dry ingredients. Cover and process until butter pieces are the size of peas, about with 8 to 10 1-second pulses. Place crumb filling/topping in refrigerator until ready to use.
  2. Preheat the oven to 350°. Grease a 9×13 inch square baking pan and set aside.
  3. To make the coffee cake: In a medium bowl, whisk together the flour, baking powder, cinnamon, and salt; set aside.
  4. In a large bowl, mix together mashed bananas, butter, sugar, eggs and vanilla until combined.
  5. Stir in milk and flour mixture until just combined (don’t over-mix).
  6. Pour 1/2 of the batter into the prepared pan. Top with 1/3 of the crumb mixture. Cover the crumb mixture filling with the remaining batter and top with remaining crumb mixture.
  7. Bake for 45-55 minutes until the center is set and a toothpick comes out clean.
  8. Cool for 10 minutes in pan set on top of a wire rack.
  9. To make the peanut butter glaze, in a small bowl whisk together powdered sugar, milk and peanut butter until smooth. Drizzle glaze over warm coffee cake and serve.
