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
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
- Preheat oven to 350°F. Line an 8×8 baking dish with parchment paper and coat with nonstick spray. Set aside
- 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.
- Bake for 30 minutes, or until the center is set.
- Transfer pan to wire rack to cool.
- Frost the blondies when they are mostly cooled.
Brown Sugar Frosting
- 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.
- Stir in powdered sugar with a whisk.
- 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.

I’m loving this blondies! I’d like to know what do you mean by “Brown sugar, light”
I’m from Chile, southamerica, and I’m not sure there is light Brown sugar available at my local grocery Shop. I was wondering if I could replace it with regular sugar instead
Thanks a lot and definitely pinned!
Mine is cooling as I’m typing this, super excited for them as they look amazing. Thanks for this recipe!
oh. My. God. These were to die. I did double in a 9×13. Will definitely make again. The frosting was fab, but really, truly, they don’t need frosting. They are perfect as is. Maybe just a scoop of ice cream!!
I made these today trying to use up some bananas. They were beyond AMAZING! Loved them. Thanks so much for sharing the recipe.
Love this recipe and its very easy to make!
These are better than any banana bread you could ever eat – I’ll never go back to the regular kind now. My frosting however turned out WAY too sugary… so think I will leave it off next time.
Just made these bad boys! With half the butter and adding cocoa to the frosting. So good
Delicious! I made these for a gathering and they were a huge hit! I doubled the recipe for a 9×13 pan and happened to have an extra banana so I used 3 instead of 2 … it resulted in what would be a “fudgy brownie” type texture. SO good! I opted not to make the frosting because I threw in peanut butter m&ms and whoppers because why not? They were gone in minutes. Definitely adding this to my arsenal! Thanks!
These are delicious – haven’t gotten around to making the frosting yet and half the pan is gone! I made a 2nd pan for friends, so they will get the frosting. I think toasted pecans would be a nice addition, maybe break up the sweet a little. But they are just wonderful. A note: browned butter is super hot. So I had to walk away and let everything cool a bit before adding eggs.
I’m going to give this recipe a try today. My tweaks will include doubling the recipe, using gluten free flour (for my mom, who has Celiac), adding dark chocolate chips, and probably adding a bit more banana – depending on how things go. I’ve read a lot of “there isn’t enough banana in here” complaints so I want to try to remedy that. I’m not a blogger, just an artist, but I do enjoy baking and tweaking recipes until they’re all my own~
I’ll try to remember to come back with my results!
can’t wait to hear how they turn out!
Doubled the recipe, shouldn’t have doubled the frosting… My frosting ended up being a half-inch thick on top of the blondies once I had cut them! The Gluten Free flour didn’t make it dry as I had feared, they were still perfectly most! Even enough that they were a bit crumbly and had to be eaten with a fork. They just had an ever-so-slight grainy texture to them that wasn’t really noticeable at all. I didn’t add any more banana, and despite my vanilla blunder (I may have read tablespoons instead of teaspoons…), they came out tasting perfectly banana! I did add the chocolate chips, bitter dark chocolate, and they added a layer of complexity to the flavour that balanced out all the sweetness perfectly. They ended up being a huge hit, and we will absolutely be making these again! I’m ready to try the marshmallow blondie recipe I saw next!
Oh, I also used dark chocolate almond milk in the frosting (I have a family full of food allergies, dairy is another one), and it made the texture of the frosting a bit more… Glaze-like? Kind of reminded me of fudge almost. But the flavour of it came out butterscotchy, which was also pretty nice! Definitely no “It tastes just like powedered sugar” here!
