Description

This moist and delicious Banana Bread Brownies recipe combines the best of banana bread and brownies into one irresistible treat. Featuring ripe bananas and a rich brown butter frosting, these bars are perfect for a quick dessert or snack, offering a delightful balance of fruity sweetness and buttery richness in every bite.


Ingredients

Batter

  • 1-1/2 cups granulated sugar
  • 1 cup plain Greek yogurt (or sour cream)
  • 1/2 cup butter, softened
  • 2 large eggs
  • 3-4 ripe bananas, mashed
  • 2 teaspoons vanilla paste
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 3/4 teaspoon salt

Brown Butter Frosting

  • 4 Tablespoons butter
  • 2 cups powdered sugar
  • 1 teaspoon vanilla paste
  • 1-2 Tablespoons milk


Instructions

  1. Preheat Oven: Preheat your oven to 375 degrees F and grease a 9×13 inch baking pan with non-stick cooking spray to ensure the brownies don’t stick during baking.
  2. Mix Batter: In a large bowl, cream together the granulated sugar and softened butter until smooth. Beat in the Greek yogurt (or sour cream), then add the eggs, mashed bananas, and vanilla paste, mixing until well combined.
  3. Add Dry Ingredients: Sift in the all-purpose flour, baking soda, and salt. Gently fold the dry ingredients into the wet mixture until just moistened, taking care not to overmix to keep the brownies tender.
  4. Bake: Spread the batter evenly into the prepared pan. Bake for 23-28 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs.
  5. Prepare Brown Butter Frosting: While the brownies bake, melt butter in a large skillet over medium heat. Let it simmer until it turns a delicate brown color and emits a nutty aroma, being careful not to burn it. Remove from heat immediately.
  6. Make Frosting: Whisk the powdered sugar, vanilla paste, and 1 tablespoon of milk into the warm brown butter until smooth. Adjust consistency by adding more milk to thin or more powdered sugar to thicken as needed.
  7. Frost Brownies: Once brownies are warm from the oven, pour the frosting over the top and gently spread it with the back of a spoon to cover evenly. Let the frosting set slightly before slicing and serving.

Notes

  • Use very ripe bananas for the best flavor and natural sweetness.
  • Be careful not to overbake to maintain a moist texture.
  • If you prefer, walnuts can be added to the batter for extra crunch.
  • Brown butter frosting adds a unique nutty flavor that pairs beautifully with the banana base.
  • Allow the frosting to cool slightly before slicing to prevent it from running.
