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! If you love desserts with bananas, or just need a great recipe to use up ripe bananas, be sure to also try my Chocolate Chip Banana Bread.
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!
