Banana blondies with brown sugar frosting are a delicious treat, combining the moistness of bananas with the richness of blondies and the sweetness of brown sugar frosting. Here's a recipe for you:


For the Banana Blondies:

1/2 cup unsalted butter, melted
1 cup light brown sugar, packed
1 large egg
1 teaspoon vanilla extract
1 cup mashed ripe bananas (about 2 medium bananas)
1 cup all-purpose flour
1/2 teaspoon baking powder
1/4 teaspoon salt

For the Brown Sugar Frosting:

  • 1/4 cup unsalted butter
  • 1/2 cup packed light brown sugar
  • 2 tablespoons milk or cream
  • 1 cup powdered sugar
  • 1/2 teaspoon vanilla extract


 For the Banana Blondies:

  1. Preheat the oven: Preheat your oven to 350°F. Grease or line an 8x8-inch baking pan with parchment paper.
  2. Mix wet ingredients: In a large mixing bowl, whisk together the melted butter and brown sugar until well combined. Add the egg and vanilla extract, and mix until smooth.
  3. Add mashed bananas: Stir in the mashed bananas until evenly incorporated into the mixture.
  4. Combine dry ingredients: In a separate bowl, sift together the flour, baking powder, and salt.
  5. Mix batter: Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
  6. Bake: Pour the batter into the prepared baking pan and spread it out evenly. Bake in the preheated oven for 25-30 minutes, or until the blondies are golden brown and a toothpick inserted into the center comes out clean.
  7. Cool: Allow the blondies to cool completely in the pan on a wire rack before frosting.
For the Brown Sugar Frosting:

  1. Prepare the frosting: In a small saucepan, melt the butter over medium heat. Add the brown sugar and milk, and stir until the sugar is dissolved and the mixture is smooth.
  2. Boil: Bring the mixture to a gentle boil, then remove from heat and let it cool for a few minutes.
  3. Add powdered sugar: Gradually whisk in the powdered sugar and vanilla extract until smooth and creamy. If the frosting is too thick, you can add a little more milk to reach your desired consistency.
  4. Frost the blondies: Once the blondies have cooled, spread the brown sugar frosting evenly over the top using a spatula.
  5. Chill: Place the frosted blondies in the refrigerator for about 15-20 minutes to allow the frosting to set.
  6. Slice and serve: Cut the blondies into squares and serve. Enjoy the delicious combination of banana blondies and brown sugar frosting!
