Ingredients

  • 1/2 cup unsalted butter, room temperature
  • 3/4 cup granulated sugar
  • 1 egg
  • 1 1/2 tsp vanilla extract
  • 1 cup mashed banana, from about 3-4 medium bananas
  • 1/2 cup buttermilk
  • 1 1/2 cups all-purpose flour
  • 1 tsp baking powder
  • 3/4 tsp baking soda
  • 1/4 tsp plus 1/8 tsp salt
  • 3/4 cup mini chocolate chips
  • 1 batch crumb topping

Instructions

  • Preheat oven to 350°F. Grease and flour an 8"x8" square pan.
  • Add butter and sugar to a large mixing bowl and cream for a few minutes until fluffy.
  • Mix in egg, vanilla, mashed banana, and buttermilk.
  • In a separate mixing bowl, whisk together flour, baking powder, baking soda, and salt.
  • Add the dry ingredients into the bowl with the wet ingredients and mix until just combined. Stir in mini chocolate chips.
  • Pour out mixture into the prepared pan, smoothing the top with a spatula.
  • Prepare 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 cool in the pan before slicing.

Notes

It's important to use buttermilk here instead of just regular milk, because the acidity is needed to react with the baking soda so this chocolate chip banana crumb cake can rise in the oven.
