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!

How to Make Ooey Gooey Banana Bars

This batter is made up of melted butter, a fair amount of brown sugar, and much less flour than normal which is great for a soft and chewy dessert bar. But the addition of the bananas in the mix, as well as the homemade salted caramel buttercream, really makes these bars a special treat.

  1. First, combine the melted butter and brown sugar in a large bowl. Stir well before adding the vanilla and eggs.
  2. Next, add the flour and salt, mixing well.
  3. Then, fold in the mashed bananas. It is fine if there are a few chunks of banana in the mix.
  4. Finally, bake at 350°F for 45 minutes, or until the center is set.
  5. Let the bars cool completely before adding the buttercream.

How to Make Salted Caramel Buttercream

Having your butter and milk at room temperature helps greatly in this buttercream recipe. You can substitute whipping cream for milk, but it is not necessary if you get the butter whipped up nicely. (I do not recommend skim milk in this recipe.)

First, in a stand mixer with a paddle attachment, combine the butter, confectioners’ sugar, salt, and caramel topping. Mix on low until every ingredient is combined. Next, mix it on high for a couple of minutes, or until the buttercream is smooth and fluffy.

Finally, add the milk. The milk is added for your desired consistency, so start with just a little bit, and continue to add more milk to make it smoother. Buttercream can be made in advance, so to save some time, make it ahead of time! Store it in the refrigerator for up to a week or the freezer for up to 3 months.

  • Deb Baldwin says:

    Ms. Amanda…Thank you for the no nonsense method of cooking: Baking…My question is…I can’t have cane sugar and totally refuse to use artificial sweetness even stevia…Can I use dates, honey and or maples syrup…along with coconut sugar or pineapple to replace the brown sugar in this recipe? I really love cooking and baking, struggle to find QUALITY recipes that do not use so much cane products. Well please let me know ..thanks! Deb

    • Amanda Rettke says:

      Hi Deb! Baking with those ingredients is not my specialty, so I am not comfortable advising on to make them shine in recipes! However, there are so many wonderful sugar-free or natural sugar options recipes out there. I know you will be able to find something that works for yoU!

  • Angie Darby says:

    I am going to try to make the Banana Bars and the Salted caramel cream Butter sounds like it will be out of this world! Do you think that topping would be good on Banana bread also?Happy l found you looks like you got some great things!!

    • Amanda Rettke says:

      Hi Angie! The frosting is really sweet but definitely versatile. It would be perfect on lots of cakes! I love banana bread and can’t imagine it would hurt to add it!

    Great recipes

  • Amanda Naude says:

    Confectioners sugar? Is it icing sugar

    • Amanda Rettke says:

      It is confectioners sugar, or powdered sugar, in the USA. It can be referred to as icing sugar, but confectioners sugar is correct.

  • Glenda says:

    These bars have a brownie consistency. They are so good! A definite keeper! Thank you for the recipe! I opted not to frost. I’ll save the buttercream recipe for another time.

  • Karen says:

    I forgot to turn my oven temperature down by 25 degrees because of using a dark coated pan, but I took the banana bars out before they burnt. Lol
    Other than my own mistake, the bars were easy to bake. Thank you for sharing this recipe.

  • Lisa Anderson says:

    Made these today. Such a nice little treat and switch up from banana bread (which I love). So easy too.

  • Sharon Carver says:

  • Penny Howard says:

    These were easy enough to make. The frosting was delicious and I added an extra spoonful of caramel just because! It was really good. My hubs thought next time use chocolate chips in the mix so I sprinkled some mini chips on his and he loved it. Thanks for the change from always using bananas in bread. We will definitely enjoy these yummy bars again!

  • Colette says:

    The recipes I have made -posted by you – have been absolutely excellent! 🎉✅ Yesterday I made the ooey gooey banana bars and they did not turn out ooey gooey at all. The base was really quite dry. I am not sure if it should have been made in a smaller pan – there wasn’t any call for baking soda/powder to add. Suggestions?
    Thank you!
