These Banana Blondies are dense yet soft, moist, and full of sweet banana flavor. Topped with a creamy, caramely brown sugar frosting, they’re irresistible!
Banana Blondies are a family favorite
Everyone loves their incredible banana and brown sugar flavor! They’re perfectly moist and dense, almost fudgy – just like a good blondie should be.
And they’re topped with a rich, creamy, caramely brown sugar frosting. Just a light layer-because these bars are rich!
Move over Banana Bread, there’s some real competition for those brown-speckled bananas!
I love my Chocolate Chip Banana Bread. It’s always been my go-to recipe for those super ripe, brown speckled bananas on the counter that no one wants to eat (but are perfect for baking).
But since I’ve been making these Banana Blondies, it’s had to share the spotlight. They’re that good!
Perfect for potlucks, barbeques, and bake sales
These Banana Blondies are such a hit at potlucks, barbeques, and bake sales. They’re easy to make, easy to transport, and easy to serve.
This recipe uses an 8-inch by 8-inch baking pan, yielding 16 2-inch by 2-inch bars. The recipe can easily be doubled to fit a 9 by 13-inch pan. Just add a few minutes to the baking time.
Use very ripe, heavily speckled bananas
Heavily speckled or even mostly brown bananas make the most moist and flavorful Banana Blondies. As bananas ripen their starch turns to sugar, becoming sweeter and more flavorful.
Smash them with a fork for the best texture and flavor.
How to make Banana Blondies
Banana Blondies are super easy to make by hand in just one bowl, plus a small pan for the frosting. No mixer required.
All of the ingredients except the flour are whisked together thoroughly in a mixing bowl, then the flour is gently stirred in until just combined. Transfer batter to baking pan and bake.
How to bake Banana Blondies
Bake until center is set and the edges are golden. A toothpick inserted into the center should come out clean or with a crumb or two, but not raw batter. About 20 minutes.
How to make the 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, then whisk in powdered sugar until smooth.
Spread on top of cooled blondies. Allow frosting to set before cutting into squares.
How to cut and serve Banana Blondies
There are two different ways that I cut and serve Banana Blondies, depending on the occasion.
The easiest way is to cut the blondies into squares and serve right from the pan. This is also easiest for transporting and serving to a crowd. In this case, I would just spray the baking pan with nonstick baking spray.
Other times, I want perfectly cut bars. I bake the blondies in a removable-bottom springform pan for easy removal and cutting into squares. If you don’t have a removable bottom, line the pan with a piece of aluminum foil with overhanging edges to make it easy to lift the cake out of the pan before cutting into squares.
How to store and freeze Banana Blondies
Banana Blondies will keep for 3 days at room temperature in a closed container or with plastic wrap tightly covering the top of the pan.
They can also be frozen whole in the pan or in individually wrapped squares. Thaw at room temperature. For individual squares, heat in the microwave until the blondie is lightly warmed, but the frosting is not melted.

Kelly, your Banana Blondies look mighty tasty and would sit proudly next to a mug of steaming hot coffee on this cool fall day . Blondies bars are quite popular here appearing in most coffee shops, but I’ve never seen or tasted a banana blondie. Something I think our neighborhood kids (young and old) might enjoy. Thanks for sharing.
Ron, they’re wonderful with a cup of coffee! They’re the perfect combination of soft, dense, and creamy. And the flavors are fantastic! Thanks so much!

It’s wonderful! And so perfect with the banana! Thanks so much, Katherine!
What a fun idea, Kelly! I love the sound of these blondies. They’re kinda like the perfect combination between summer (banana bread) and fall (brown sugar frosting). I know I would gladly find a way to make several of these disappear! 🙂
Taking teeny, tiny baby steps into fall, David! It’s actually my favorite season, but I hate the end of summertime fun and produce. Or I just don’t like change 🙂 Thanks so much!
I love that frosting so much, I could eat it by the spoon! It’s my total favorite. We call it “penuche” frosting. Anyway, these blondies look phenomenal! Pinning!
Oh yes, that name is familiar! It goes perfectly with banana! Thanks so much, Laura!
The picture of the loaf pre-cut is outstanding! Your photos are making my hungry! Not to mention the flavors!! Pinned!
I love this frosting! And the bars just melt in your mouth – so perfect together! Thanks so much, Annie!
I bought 5 pounds of overly speckled bananas today for a dollar! I was wondering what to do with them . The chocolate chip banana bread looks perfect.
Oh, Judee, that’s awesome! I’m always waiting and waiting for my bananas to brown. I usually hide some so they don’t all get eaten before they’re ready! 🙂 I could really go to town with 5 pounds of ripe bananas! Thanks so much!
I would choose these over banana bread every day! I love the flavor that brown sugar imparts, and that frosting is the perfect way to top these bars off. These look amazing Kelly!
They sure give banana bread a run for it’s money! Thanks so much, Marcie!
Love that frosting! And the blondies themselves look really good, too. Neat recipe — thanks.

They’re so melt-in-your-mouth delicious! Thanks so much, Taruna!
Thanks for the wonderful easy recipe. They did not last long in my house. I suggest if you double the recipe to NOT double the frosting. It was too thick. My gang asked for another batch the next day!
Thanks so much, Kristy! So happy you liked them!
