Ooey Gooey Banana Bars are sweet and moist dessert bars that are loaded with bananas and frosted with homemade salted caramel buttercream. Although these bars would be delicious on their own, the frosting puts this dessert over the top!

Ingredients & Substitutions

Butter: Use unsalted butter for both the bars and the salted caramel buttercream.

Brown Sugar: These bars are rich dessert bars that are made with brown sugar to give them that extra sweetness.

Bananas: Mash a couple of bananas to use in the bars. You need about 2/3 cup of mashed bananas.

Caramel Sauce: Skip the store-bought caramel sauce and make your own to use in the salted caramel buttercream!

Can These Bars be Gluten-Free?

I stress this often, that I am not a gluten-free specific baker. However, a few readers have mentioned that this recipe works very with a high-quality gluten-free replacement.

Storing & Freezing Ooey Gooey Banana Bars

This cake is best served fresh! However, you can store it in an airtight container (or covered with plastic wrap) in the refrigerator. You can also freeze this cake, however, I do recommend waiting to frost the cake until after thawing.

Can I Make the Bars Without the Frosting?

Yes, of course. However, the salted caramel buttercream truly is magical on these bars and I do hope you’ll give it a chance!

  1. My family begs for these anytime I have brown bananas. I start testing for doneness at 30 minutes-they were done at 35 minutes. I always put the frosting on when the bottom of the pan is still a little warm and love how a tiny bit of the icing kind of melts into these bars. You seriously need to make these. So. Darn. Good.

  2. I don’t like “salted caramel” but love caramel! How do I make the icing as just regular caramel buttercream?

  3. Best banana bars I’ve tried in a long time! Didn’t realize I didn’t have powdered sugar until it was too late and used regular sugar instead in the frosting. Texture was a little off but still tasted great! Thanks for the new fav recipe!

  4. They weren’t ooey or gooey and not enough banana flavor. I gently spooned in the fluffed up flour, so I know that I didn’t use too much flour. I also took them out of the oven 5 minutes early. They’re not horrible but they weren’t anything like I was expecting or hoping they’d be….

    1. Sorry to hear that. Did they look like my pictures? Unfortunately, every oven is different and yours just may heat differently and the bars may be a tad overbaked. In that situation I agree, they would still taste ok, but not be super soft.
