Banana Bars with Brown Butter Frosting

For those that follow me on instagram, you may have seen my post some bars- these are NOT them, but they are good! That recipe will hopefully be coming in the next week :)

Do you have some ripe bananas? Need a recipe to make with them? Give these bars a try! My sister has been making this recipe for a year or so now which comes from The Girl Who Ate Everything. She is not a chocolate person at all (unlike me) and always brings these when she is in charge of dessert. They are amazing!

The Brown Butter Frosting is similar to one that is already on the blog, but compliments the banana flavor PERFECTLY! This recipe is just like Banana Bread, only more cake like and made into bars :) You definitely need to give these a try- you won’t regret it!

    I've seen this recipe floating around for years now and I have always wanted to try it as written and always end up tweaking and fiddling but now I just have to make these like this! I love banana bread and these look awesome, Nikki! Pinned :)

    I am a chocolate person but these bars with the browned butter frosting sounds amazing. I will be making soon.

    Sounds delicious. I found a quick way to mash
    the bananas by pulsing them in my cuisinart for about 5-10 seconds. They come out perfect for a recipe like this one. I'll be trying the banana cake this week. Yummy.

    what did I do wrong?! I only got 2 cups of the powdered sugar in before it turned into a thick, pasty mess with the glaze.

      I figured it out! you have to only use 1 tbsp. of milk. When I checked the recipe source it said 3 tbsp. P

      I had the same thing happen! Thank goodness you directed me to the source recipe for the correct measurements! Nikki may want to update her version with the corrected measurement. Can't wait to try these! Just letting them cool now!

      Bad mistake in frosting milk measurement. I used 5 tbs of milk.

    These were excellent! I just made them tonight. Has anyone tried adding chocolate chips? Also at the top of the page it says "For those that follow me on instagram, you may have seen my post some bars- these are NOT them" Which bars are those??? These were so yummy!

    These are so moist and tasty, easy to make and everyone loves them! I have made them twice and received numerous compliments:) I even used whole wheat flour for one-half of the flour, and I used crème cheese frosting.

    Adding a pinch of salt to browned butter icing really enhances browned butter icing.

      Even if we use salted butter?

    Made these for Thanksgiving and had to make 2 extra batches for the company. Highly addictive! VERY VERY GOOD.

    This recipe sounds delish. Do you have to make it in a jelly roll pan? I don't have one...

    Hello there! I'm new to your website and this recipe looks like what I need in my life right now! I had a question on the bananas. I don't have any ripe bananas at home so when I do go to the grocery store, could these bars be made with fresh bananas/bananas that hasn't ripen yet? Or will it take away from the entire taste aspect? Thank you!

  13. Tina

    It was so easy to make and tastes awesome
