Rich decadent banana blondies with caramel icing

My Favorite Banana Blondies recipe ~  think banana bread meets blondies, this easy dessert is rich, dense, and fudgy, with a to-die-for caramel frosting!

These blondies are utterly addicting - proceed with caution!

Banana Blondies with Caramel Icing

These Banana Blondies are as addictive as anything I’ve had in my life,

and I have to say it took me a little bit by surprise — they look so innocent!  But the combination of the very dense banana cake and the very sweet caramel icing is intense.  I tested the recipe on 2 consecutive days, and my self control failed miserably.  I spent 48 hours in a banana blondie induced coma.  Proceed with caution.

I ate these warm out of the oven…I ate them chilled from the fridge the next day…suffice it to say I’ve had them every which way and every way was amazing.

Simple Banana Blondies

Self control issues aside, I’m so happy with this recipe, it’s reliable and easy to do.  if you’re a banana lover, or just happen to know one, this is a must try.  There is a ton of banana flavor packed into these slim bars, which also surprises me because I only used one banana.  They are moist and dense, almost like a banana fudge, (if that thought doesn’t blow your mind.)   They’re good.

Banana Blondies with Caramel icing

If you’ve got one ripe banana, the rest of these easy bars come together from the pantry.

The frosting is a quick cooked caramel, but don’t let that scare you, that just means you melt some butter, brown sugar, and a touch of cream or milk together in a saucepan and heat it to a boil, then whisk in powdered sugar. It’s not fussy at all, but it does set up quickly, so plan to slather it on the cake right away.  You can actually cut these and eat them warm, which is unusual for a frosted dessert.

Do yourself a favor….make these.  😉

My Favorite Banana Blondies ~  think banana bread meets blondies, this easy dessert is rich, dense, and fudgy, with a to-die-for caramel frosting!
Course Dessert
Cuisine American
Prep Time 10 minutes
Cook Time 25 minutes
Yield 9 servings

Ingredients

  • 1/2 cup 1 stick unsalted butter, melted
  • 1 cup packed brown sugar
  • 1 large egg
  • 1 1/2 tsp vanilla extract
  • 1/4 tsp salt
  • 1 cup all purpose flour
  • 1/2 cup well mashed banana about 1 to 1 1/2 bananas

caramel icing

  • 1/4 cup 1/2 stick unsalted butter
  • 1/2 cup packed brown sugar
  • 2 Tbsp cream or milk
  • 1 cup powdered confectioner's sugar (possibly a little bit more)

Instructions

  • Set the oven to 350F
  • Beat the butter and sugar together for several minutes until smooth and fluffy. Beat in the egg and vanilla.
  • Mix in the mashed banana, and then the flour and salt. Mix just until everything is well blended, don't over mix.
  • Spread into an 9x9 square baking dish. I like to spray the dish with baking spray and also line it with parchment paper with long ends so I can lift it out to frost and cut it easily.
  • Bake for 25 to 30 minutes, until the center is set. I check with a toothpick.
  • Let the cake cool most of the way before you make the frosting.
  • To make the caramel frosting put the butter, brown sugar and milk or cream in a small saucepan and melt the butter, whisking all the time. Continue whisking until the mixture comes to a boil, then turn off the heat and add the sifted powdered sugar, whisking until completely smooth. You may need to add a little bit more powdered sugar if it seems very thin.
  • Spread it immediately onto the cake, it will set up very quickly.
  • Enjoy!

    Can I use dark brown sugar instead of light? And if so, should I modify the amount?

    Does anyone know if the icing would work if made using a dairy alternative milk, like almond milk, or coconut milk? Thank you!

      I’d say that works! But just in case you can search for other recipes using nondairy milks and/or search what properties milk does for icing. Hope this helps!

    These are now a go-to in our house! We have made these several times already since recently discovering this recipe (we don’t make the icing, love them as is). I’ve actually started making them in mini muffin pans (sometimes adding chocolated chips) for bite-sized treats/snacks. My 2-year old LOVES them; toddler and adult approved!

    These are delicious! I wanted to use up my turned bananas, but was also wanting a change from banana bread. This recipe is a keeper in my book. Now, this wasn’t an issue for me, but it probably would be for some. The icing maked it pretty sweet. So, if you’re not a huge fan of really sweet, maybe you could use a cream cheese frosting or something. Thank you for a great recipe!

    I LOVE this recipe. My son told me it was his new “favorite flavor” ? I usually have a little trouble getting the top done and have to cook it a little longer, but that’s probably just my terrible oven. Other than that, I follow this recipe exactly and have awesome results.

    Why do you have to spray your dish if you are going to line it with parchment paper? Am I missing something?

    • Reply
      Sue
      May 25, 2020 at 10:31 am

      That helps the paper stick and stay put, so when you spread the blondie batter into the pan, the paper doesn’t slide all around.

    These are hands down the best! Do not waste your time on an 8×8. Double the recipe and use a 9×13…trust me. My hubby and daughter finished the whole pan in a day and a half! And two days later, I had to make them again for her birthday. They are amazing! I added walnuts the second time…served with a scoop of vanilla ice cream….pure heaven

    We made these tonight – delicious! I used 2 very ripe, small bananas. I melted the butter before I saw that it said to “cream the butter and sugar” – turned out fine! I only had salted butter, so I halved the salt. I used an 11×7 inch pan. It is a little tricky to know when they are done because the batter is brown; the toothpick came out clean at 22 mins, but I could see that they were still gooey so I left them in for the full 25 mins. They were almost not quite cooked through once I sliced them. I’ll let them brown up a bit more next time. My frosting was much darker than yours, and very sweet. Delicious, but I might try add a dollop of cream cheese as others have suggested, or maybe a dash of salt. Also, I am at altitude and did not need to make any adjustments! Thanks for sharing this!

    Ok this may be a “blondie” question (no pun intended lol) How do I cream butter and sugar if the recipe calls for it to be melted. Is the top section supposed to say melted?

      They are thin, but shouldn’t be gooey, sounds like yours didn’t get baked long enough. That could be an oven temperature issue.
