For the Banana Blondies:

  • 1 1/2 cups all purpose flour
  • 1/2 tsp baking powder
  • 1/2 tsp fine sea salt
  • 1/2 cup unsalted butter (melted)
  • 1 1/2 cups light brown sugar (packed)
  • 3/4 cup mashed banana
  • 1 large egg
  • 1 tsp vanilla extract

For the Cream Cheese Frosting:

  • 8 oz cream cheese (block, softened)
  • 1/2 cup unsalted butter (softened)
  • 2 cups powdered sugar
  • 1 tsp vanilla extract


For the Banana Blondies:

  • Preheat the oven to 350 degrees Fahrenheit. Line a 9x13 baking dish with parchment paper, and set it aside.
  • In a medium sized bowl, add the flour, baking powder and salt. Stir them together, and set aside.
  • In a large bowl, add the melted butter, brown sugar, mashed banana, egg, and vanilla, and whisk them together until smooth.
  • Add the dry ingredients to the wet ingredients and stir them together until there are no dry patches.
  • Spread the batter into the prepared baking pan.
  • Bake the bars in the preheated oven for 30 to 35 minutes, until the edges are golden and a toothpick can be inserted into the middle, and comes out clean.
  • Place the pan onto a wire rack to let them cool completely.

For the Cream Cheese Frosting:

  • Add the cream cheese and butter to a a large bowl and whip them together until smooth with a hand mixer, or stand mixer. Scrape down the sides a couple times as you go.
  • Add in the powdered sugar and vanilla extract, and mix them on low speed until combined. Raise the speed to medium and let the frosting beat until it is light and fluffy, about 3 minutes.
  • Lift the blondies out of the pan with this parchment paper, and spread the frosting evenly over the top of the bars.
  • Cut the blondies into pieces and serve immediately.
