Ooey Gooey Banana Bars

These bars are rich dessert bars that are made with brown sugar to give them that extra sweetness. They are moist and dense with a wonderful banana flavor in every bite. Although these bars would be delicious on their own, the homemade salted caramel buttercream frosting puts this dessert over the top!

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 absolutely freeze this cake, however, I do recommend waiting to frost the cake until after thawing.

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.

  1. I would advise to check on these banana bars at thirty minutes.I left them in the oven for forty-five minutes like the directions stated and they came out too done.

  2. So I saw a recipe for apple bars with crumbles on top, would love to try this with banana slices but not sure if they will hold up bc bananas are much softer and turn quicker than apples, any suggestions?

  3. EXCELLENT! And even better the next day.
    I WORSHIP sugar, but might cut it back about 5% next time…..maybe?…… I dunno.
    My oven was just tuned up and calibrated, so it’s temp accurate….for now. I say this because the bars were done in 30 minutes. Will be making this again for sure! Thank you! <3
