Do you have some brown bananas sitting on your counter waiting to be used? Well, today is their lucky day! My Banana Blondies are so amazing and reason enough to go out and buy bananas now if you don’t have any. This is a simple and indulgent recipe that is just different enough. The familiarity of the banana flavor will make sure that everyone of all ages will fall in love.

BANANA BLONDIES

If you are unfamiliar with a blondie, then your day is about to get a whole lot better. First, let’s start with a brownie. Who doesn’t love this classic dessert? Especially served warm with a scoop of vanilla ice cream. A blondie is very similar, just not rich with chocolate. Traditionally a blondie is more of a vanilla style brownie. But this recipe takes everything to a new level.

These blondies start with a very straight forward batter with butter, eggs, flour, and brown sugar. Mashed bananas join the party to make this as fun as a barrel of monkeys. Now, a piece of this on its own would be fruity and flavorful, but you know I’m not going to stop there. A 4-ingredient brown butter frosting is lathered over everything which makes each bite utterly irresistible!

INGREDIENTS

Blondies

  • 1 cup salted butter, melted
  • 1 ½ cups light brown sugar
  • 2 large eggs
  • 2 teaspoons vanilla
  • 1/4 teaspoon salt
  • 2 cups all-purpose flour
  • 1 cup mashed banana (about 2 medium bananas)

Brown Butter Frosting

  • 1/4 cup salted butter
  • 1/2 cup packed light brown sugar
  • 2 Tablespoons milk
  • 1 cup powdered sugar

INSTRUCTIONS

BLONDIES

Preheat the oven to 350°F. Line a 9×13-inch baking dish with parchment paper then spray with cooking spray. Set aside. In the bowl of a stand mixer, add melted butter and sugar. Mix until combined. Add in eggs and vanilla and continue mixing until incorporated. Stir in salt, flour and banana until batter is smooth. Spread evenly in the prepared pan. Bake for 25 to 30 minutes, or until the center is set. Remove from the oven and let cool before frosting.

BROWN BUTTER FROSTING

In a medium saucepan, melt butter over medium-low heat until butter starts to barely brown and becomes very aromatic (about 5 minutes). Add the brown sugar and milk to butter. 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. Allow frosting to set before cutting into squares.

SERVINGS

One pan of this freshly baked dessert makes up to 24 servings. Now, everything depends on how you slice it, and these are rich! If you have some little monkeys in your house who love bananas, perhaps you can cut larger squares, but to make this last as long as possible I recommend sticking to the 24 squares.

BANANA BLONDIES CAN BE GLUTEN FREE

To make these blondies gluten free, all you need to do is substitute the all-purpose flour with your favorite brand of gluten free flour.

FROSTING

It’s important to let the blondies rest and cool before frosting them. Otherwise, the brown butter frosting will get runny and not adhere correctly. After they are frosted, they are ready to serve!

STORING

Store any leftovers covered on the counter for up to 3 days, or cover and store in the fridge for up to 5 days.

  1. I have a bunch of brown bananas on my counter right now and I told my kids tonight when they get home we were going to make banana bread. I might have to rethink that now and make these instead! They look delicious! You rock Holly!

    1. Mine came out BEYOND sweet! I must’ve done something wrong. I didn’t even put in all the brown sugar the recipe called for.

  2. Made these last week. The BEST use of old bananas!!!! My son took them to high school and shared. The kids said these blew away anything that Starbucks sells. They were awesome!! Thanks for sharing!

  3. My boyfriend would absolutely love these! What a great idea to use up left over bananas instead of making banana bread. Definitely going to give these a go instead of throwing my bananas away!

  4. I was looking for a way to use up my old bananas without making banana bread or muffins AGAIN. Glad I came across this. OMG so good!! My 5 year old loved them!! Next time I need to bring something to an event I am making these!!!
    I won’t be happy when I step on the scale…I can’t stop eating them

  5. I made these and they were more cakey than a bar but still good. I refrigerated them and the icing got really hard. If I took them out to get to room temp, would that work? I have to make them a day ahead for a group.

  6. Oh my goodness these are delicious!! I halved the recipe but added a little extra mashed banana, ’cause why not. So moist and tasty…thank you!

  7. In the process of making the banana blondes. Waiting for them to cool so I can make icing. The smell was divine and filled the house. If they taste as good as they smell this is going to be a winner. So over banana breadsticks. Haha!

  8. My husband isn’t a huge sweets guy, only banana desserts and ice cream. This is the first dessert I’ve made that he loves and gobbled up!!! They are amazing!! Thank you! Now I know what to do from now on with my old bananas!!!

  9. Just found your recipe. It’s delicious! I added pecans on top for crunch and another layer of flavor. The perfect marriage between banana bread and blondies 🙂

  10. I made these and they were just ok. For me, 2 cups sugar AND bananas (which contain lots of natural sugar) AND frosting made these too sweet. I feel like they need more salty balance to be a delicious dessert (toffee? salted caramel?). Maybe bittersweet chocolate ganache on top instead. They are quite cakey, rather than bar-like. I also suspect they could be done with less butter. Still, I like the banana idea.

    My sister loves bananas, and I hate them, so I’m always worried whether or not all the banana pastries I make will get eaten. Not anymore! These are beyond scrumptious! Thank you!

  12. These look delicious and are in the oven now! What is the beat way to store thEse after theyve been baked and frosted?

    1. I hope you enjoy them Sam! we love these bars so much. I personally like to store them in the fridge because I love them cold. But you can store them covered at room temperature too.

  13. 4 stars
    I just made these and they are delish! Im so happy i stumbled upon this recipe. I cut 1/2 the butter with applesauce and reduced the sugar a bit and they’re fantastic! The icing is amazing!

    I was looking for an alternative to banana bread to use up my aging bananas. I am so glad i found this recipe! I made These intO individual portions in Cupcake liners in my muffin pan. They are diVine. And, the brown butter frosting makes them extra special. The kids loved them. (There’s potassium in bananas, so it’s a healthy snack, right? ) I will definitely make tHese again.

    Thumbs Up fRom the fam!

  19. 5 stars
    These are so good but very sweet! if you want to break up the sweet, i added sliced strwberries and blueberries to the top of mine and it was super tasty. it kind of made it into a fruit pizza but it was still amazing without the addition.

  20. 5 stars
    Fantastic –perfect use for brown bananas. recipe was easy to make and the finished product was thoroughly enjoyed by the fam. we will be making these again (and again)!

  21. 4 stars
    I was looking for a recipe to keep two very ripe bananas from going to waste. Not The usual banana bread or muffins. I happened onto this recipe. These blondies are very sweet, but so delicious! I especially love the browned slightly crispy edges. I added sprinkles because I’m taking them to give to some family and friends. I think I’ll try adding some chopped walnuts next time. Lovely recipe! Fast and easy!!

    1. 5 stars
      Just made them with almonds. My hubbys favorite banana and walnuts! Ill let you know! They smell amazing and the frosting yum!

  22. 5 stars
    I cant say what these are like exactly as wrItten in the recipe, but i made them with a few modifications and they are amazing! I used half the butter and only one cup of sugar in the batter. Also added an extra banana. Finally, i omitted the brown sugar in the icing. I dont typically like super sweet desserts, and had Read a few reviews that they were too sugary for some people. They were just the right amount of sweetness for me this way with a perfect denSe texture. Loved it and will be making again and again!

    I had a few bananas in the fruit bowl and I seen where you recently posted this recipe for frosted banana bars. So decided to make them followed the recipe as you wrote and they came out great. The recipe was very easy to make. Once they cooled and I cut them into bars and gave family members a bar all I heard was WOW these are awesome. So I will be making another pan real soon. Thank you for sharing.

    1. so I am trying the recipe but making a few additions like chocolate chips, walnuts and a few white chocolate chips. will let you know how it goes

  24. 5 stars
    I HAD RIPE BANANAS AND WAS TIRED OF BANANA BREAD. I FOUND THIS RECIPE. IT IS EASY AND ABSOLUTELY DELICIOUS!!! THE FROSTING TASTES LIKE MY MOM’S HOMEMADE SOFT CARAMELS SHE MAKES AT CHRSTMAS. I MAY HAVE EATEN A COUPLE SPOONFULS OF FROSTING WHILE THE BARS COOLED. WILL DEFINITELY MAKE THESE AGAIN!!

  25. 5 stars
    I, too, was looking for an alternative to banana bread and am so happy I found this. Normally I steer away from recipes that are two part or I leave off the icing. But this was so easy! I didn’t pack my brown butter, and I ended up only doing about 2/3c of powdered sugar because that’s all I had left, but it was amazing! So moist, flavorful, and yummy. Agree these were more like a dense cake than a bar, but no one here complained! Thanks for the great recipe!

    1. You could definitely add chocolate chips to the batter. I would fold in about a cup or a little less to the batter before pouring it into the pan to bake. 🙂

  26. 5 stars
    Made these tonight just as directed (except added a 3rd banana). They were Easy to make, cooked nicely and everyone loved them. Ill add these to my rotation for the fute. Thank yOu.

  27. 5 stars
    These came out PERFECT! Thanks for an amazing recipe!! We love them!! They DEFINITELY melt in your mouth!

  28. 5 stars
    So moist and the frosting is soooo good. They are great room temperature or even chilled. I love this recipe! The family loves it and so do all of the guys where my husband works! Thank you so much! This will be a go to dessert for all my family events.

  29. 5 stars
    Came out very good, husband loved them. Very Easy recipe holly. Thank you so much. Will definitely be saving this recipe

  30. 5 stars
    Absolutely blown away with this recipe. So simple yet so delicious. I’m so glad to have found another use for old bananas rather than the same old banana cake/bread. Was a hit with the family.

  31. 4 stars
    loved these for an alternative to banana bread. I used 4 smallish very OVERRIPE bananas (just slightly more than a cup), and oat milk instead of cow’s milk. I added vanilla to the frosting and sprinkled the blondies with raw sugar, pink Himalayan salt, and a roasted butter pecan topping that gave them just the right crunch and saltiness that balanced out the sweetness. very decadent and delicious, my son ate them right up!

  32. 5 stars
    I read all of the reviews before deciding if I wanted to make this. I decided to not pack down my brown sugar for the blondies but did for the icing. I am so glad I made these. they were wonderful. I had bananas to use up and the thought of banana bread or muffins seemed blah to me. I did not find these to be too sweet. I’ve never cooked icing on the stove so that was new for me. it was delicious. thanks for the recipe, I’m sure I’ll make it again

  33. Loved how easy these were to make, love, love, love that frosting. I saw other reviewers didn’t like the sweetness, but I do!
    I had one and a half over ripe bananas, and I added a couple of tablespoons of peanut butter, and 3/4 cup butterscotch chips. These are fantastic!

  34. 5 stars
    1st time trying these, and they are amazing! I Shared these at a gathering recently, and they were a hit! thanks for sharing!

  35. Oh goodness!!! This recipe is delicious!!! Thank you for the idea of what to do with my “past their prime” bananas.

  36. These sound delicious and i happen to have 4 over-ripe bananas that i was going to use to make flourless banana pancaked. i’ll make these instead but will cut the sugar amounts in 1/2 and add walnuts to the batter. thanks for the recipes!

  37. 5 stars
    Huge hit at a recent party! Icing was a little tight and hard to spread, but got there in the end. Thanks!

  38. 5 stars
    I have made these so many times and they are always just incredible. however, this recipe makes a lot of dessert for a household with only a little bit of a sweet tooth. have you tried freezing these? curious if it would be a way to have them more often instead of waiting until there are eight people around to eat them with haha

    1. Yes you can freeze the bars! Just cool them completely, wrap in plastic or a Ziplock freezer bag (releasing as much air as possible), and freeze for up to 3 months.
