Ingredients

Cinnamon Topping

  • 5 Tablespoons light brown sugar
  • 1 Tablespoon ground cinnamon
  • 4 Tablespoons salted butter melted and cooled

Banana Cake

  • 2 large bananas mashed
  • 1/3 cup light brown sugar
  • 4 Tablespoons salted butter melted and cooled
  • 1 large egg
  • 3/4 cup buttermilk  
  • 2 teaspoons vanilla extract 
  • 1 ⅔ cups all-purpose flour
  • 3 teaspoons baking powder
  • 2 teaspoons ground cinnamon

Icing

  • 1/2 cup powdered sugar 
  • 3 Tablespoons milk

Instructions

Cinnamon Topping

  • In a small bowl, stir the light brown sugar, cinnamon, and melted butter together until combined. Set aside. 

Banana Cake

  • Preheat the oven to 350° F. Grease an 8×8-inch baking dish with baking spray. Set aside.
  • In a medium bowl, combine the mashed bananas, light brown sugar and cooled butter. Stir in egg, buttermilk, and vanilla extract. 
  • In a separate bowl, whisk the flour, baking powder, and cinnamon together until combined. Stir these dry ingredients into the wet ingredients just until combined. Don’t over mix. 
  • Spread the batter evenly into the prepared baking dish. Sprinkle the cinnamon topping all over the top of the batter. Using a butter knife, gently swirl the topping into an inch of the top of the batter. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out mostly clean. Remove from the oven and allow to cool for 30 minutes. 

Icing

  • Whisk the powdered sugar and milk together. Drizzle all over the top of the cake. Cut into squares and enjoy!
