Banana Blondies are sweet and delicious. They’re so soft they almost melt in your mouth. The browned butter frosting takes them to extra yummy levels too!

Banana blondies are a sweet and delicious dessert with banana flavor and a rich browned butter frosting. Life-in-the-Lofthouse.comI promised on Instagram that delicious things would be happening today and so here is that promise being fulfilled. I give you BANANA BLONDIES aka. the tastiest banana bars you will ever encounter. 

These Banana Blondies are so good. They’re so soft, sweet and delicious. They almost melt in your mouth. The sweet frosting is browned-butter frosting. Yep, I told you they are amazing. Don’t even ask me how many I ate. 😉 

I can’t think of a better way to use those ripe bananas sitting on your kitchen counter! This recipe makes a 9×13 pan. I cut my banana bars pretty big for the photos, but you can cut them smaller to feed a lot of people. That is, if you’re willing to share.

  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!

  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. 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

  4. 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.

  5. 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!

  6. 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!

  7. 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!!!

  8. 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 🙂

  9. 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!

    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.
