Banana Coffee Cake

  • 4 oz unsalted butter, melted
  • 159 grams (3/4 cup) light brown sugar
  • 1 egg
  • 3 overripe bananas, smashed
  • 210 grams (1 3/4 cup) all purpose flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 1 1/2 tsp ground cinnamon

Vanilla Icing

  • 85 grams (¾ cup) powdered sugar
  • 1 ½-2 tablespoon heavy cream

Instructions

Cinnamon Streusel Topping

  1. Combine the brown sugar, flour, cinnamon, and butter for the topping in a small bowl.
  2. Mix together with your hands, gently massaging the dry ingredients into the butter.
  3. Continue to mix until the butter is in pea sized pieces or slightly larger.
  4. Chill until ready to use.

Banana Coffee Cake

  1. Preheat oven to 325º F.
  2. In a stand mixer fitted with a paddle attachment, cream the butter and sugar together on medium speed until light and fluffy.
  3. Add the egg with the mixer on medium speed, and scrape down the sides of the bowl as needed.
  4. Add the smashed bananas followed by the flour, baking powder, baking soda, salt, and cinnamon. Scrape down the sides of the bowl as needed and mix just until it is incorporated.
  5. Prep an 8 inch springform pan by coating it with cooking spray.
  6. Carefully pour the batter into the pan and smooth it out with an offset spatula. Sprinkle the streusel evenly on top so that all of the batter is covered.
  7. Bake for 45-50 minutes until a toothpick inserted into the center of the cake comes out clean.
  8. Cool for 30 minutes on a cooling rack before gently running a knife along the edges. Place the pan on top of a small jar or cup and gently open the pan, pushing the sides of the pan down off of the base to release it.

Assembly

  1. Sift the powdered sugar into a small bowl and pour in the cream. Whisk together until combined.
  2. Transfer the vanilla icing to a pastry bag or use a spoon to drizzle the icing onto the cooled cake in a zigzag motion.
  3. The cake is best served slightly warmed. Enjoy!

Notes

  • Leftover cake can be placed in an airtight container and kept at room temperature for up to five days. It is best enjoyed slightly warmed in the microwave.
