Ingredients

The following ingredients have 4 Servings
  • ½ cup (8 Tablespoons) unsalted butter (softened to room temperature)
  • ¾ cup granulated sugar
  • 1 cup mashed banana
  • ½ cup (4 oz) buttermilk ((see note on homemade))
  • 1 large egg
  • 1 ½ teaspoons vanilla extract
  • 1 ½ cups all-purpose flour
  • 1 teaspoon baking powder
  • ¾ teaspoon baking soda
  • ¼ teaspoon plus ⅛ teaspoon salt
  • ¾ cup mini chocolate chips
  • 1 batch crumb topping ((or two batches, see note))
  • Confectioners' sugar (for serving)

Instruction

  • Preheat oven to 350°F. Grease and flour a square 9" x 9" pan.
  • Cream softened butter and granulated sugar in a large mixing bowl on medium to medium-high speed for 1-2 minutes until light and fluffy.
  • Add mashed banana, buttermilk, egg, and vanilla extract and mix until evenly combined.
  • In a separate mixing bowl, whisk together the flour, baking powder, baking soda, and salt.
  • Add the dry ingredients into the bowl with the wet ingredients and stir until just combined, making sure not to overmix. Some lumps in the batter are okay. Fold in chocolate chips.
  • Pour out the batter into the prepared pan, smoothing the top with a spatula so it's even.
  • Prepare the crumb topping according to recipe instructions (link in the ingredient list above). Evenly scatter crumb topping over top of the crumb cake.
  • Bake for 35-40 minutes, or until a tester inserted in the center comes out clean. Let the cake cool in the pan completely before slicing. Dust with confectioners' sugar just prior to serving.
