Ingredients

The following ingredients have 8 Servings
  • 6 Tablespoons butter melted
  • 1 1/4 cup all-purpose flour
  • 1/2 cup light brown sugar tightly packed
  • 1/3 cup sugar
  • 3/4 teaspoon ground cinnamon
  • ¾ cup unsalted butter (softened to room temperature)
  • 3/4 cup sugar
  • 3 very ripe bananas (mashed (1 ½ cups))
  • 2 large eggs (lightly beaten (room temperature preferred))
  • 1½ teaspoon vanilla extract
  • 2 Tablespoons sour cream
  • 1 1/3 cup all-purpose flour
  • ¾ teaspoon baking powder
  • 1/2 teaspoon baking soda
  • ½ teaspoon ground cinnamon
  • ½ teaspoon salt
  • 1/2 cup powdered sugar
  • 2-3 teaspoons milk

Instruction

  • Preheat oven to 350F and lightly grease and flour a 9x9 baking pan. Set aside.
  • Combine butter and sugar in the bowl of a stand mixer (or in a large bowl and use an electric mixer). Beat until well-combined, then stir in mashed bananas.
  • Add eggs, stirring well after each addition, and then add sour cream and vanilla extract and stir well.
  • In a separate, medium-sized bowl, whisk together your flour, baking powder, baking soda, cinnamon, and salt.
  • Gradually add the dry ingredients to wet, stirring until completely combined (be sure to scrape down the sides and bottom of the bowl). I prefer to do this with a spatula to avoid over-mixing the batter.
  • Pour batter evenly into prepared 9x9 pan. Prepare Streusel.
