Description

These Banana Blondies with brown sugar frosting are out of this world delicious. They’re perfectly flavored with banana and literally melt in your mouth!


Ingredients

Scale

Blondies

  • 1/2 cup butter, melted and if desired browned
  • 1 cup light brown sugar, packed
  • 1 egg
  • 1 1/2 teaspoon vanilla
  • 1/4 teaspoon kosher salt
  • 1 cup all purpose flour
  • 1/2 cup mashed banana (1 medium banana)

Brown Sugar Frosting

  • 1/4 cup butter
  • 1/2 cup light brown sugar
  • 2 tablespoon milk
  • 1 cup powdered sugar


Instructions

Blondies

  1. Preheat oven to 350°F. Line an 8×8 baking dish with parchment paper and coat with nonstick spray. Set aside
  2. In a large saucepan melt the butter (and if desired continue cooking the butter until it’s amber in color, stirring frequently *see note). Allow the butter to cool for 5 minutes and stir in the brown sugar, vanilla, and salt to combine. Stir in the egg until smooth and finally the flour and mashed banana. Spread in prepared pan.
  3. Bake for 30 minutes, or until the center is set.
  4. Transfer pan to wire rack to cool.
  5. Frost the blondies when they are mostly cooled.

Brown Sugar Frosting

  1. In a medium saucepan melt butter. Add brown sugar and milk and stir until mixture comes to just a boil. Remove from heat, allow to cool for 5 minutes.
  2. Stir in powdered sugar with a whisk.
  3. Spread on top of blondies and allow frosting to set and blondies to cool completely before cutting into squares.

Notes

If you choose to brown the butter, melt butter in saucepan and continue cooking, once it’s melted by swirling the butter in the pan until butter reaches a deep golden brown color.

  1. These are absolutely delicious! The blondies are wonderful, but loved them even more with the yummy frosting!! Thank you for another fantastic recipe!

  2. These were so delish!! The only thing for me was that it was a bit too sweet, and I didn’t even use the recommended amount of sugar, I used less, so next time I’ll use even less. But otherwise, wow!! added to my favorite dessert list. Thank you!!

    1. And btw, I didn’t need the frosting, too much sweet for one day LOL. plus they were already so delish by themselves.

      1. Ohhh also anyone who’s vegan, could use about 1/2 tsp baking powder and 2TBSP unsweetened applesause, I did this and it worked for me!

  3. Shelly, Next time, just state, “Sugar Queen” or “Butter Master”. I too have one of those jobs that no one understands. I do sales for a web-based company that no one local has heard of. *sigh* It’s so much easier to just tell people I’m a welder.

    Please keep these wonderful posts coming!
