Banana Bars Recipe

I am usually a brownie lover, but after trying these banana bars I don’t think I’ll ever go back! Not only do they taste amazing, but they are so easy and quick to make.

    Yum! We love ours with cream cheese icing on top. I've done banana bars for over 10 years and substituted out different flours and applesauce instead of butter or oil with good results!

    I had some very ripe bananas in need of a recipe, and I came across yours! I used less sugar (1 cup instead of 1.5), plain non-fat Greek yogurt, and whole wheat flour. I also skipped the glaze and these bars came out great! Thanks!
  3. The first time I made these they turned out looking and tasting exactly like banana bread (I made in a 9x13 casserole dish) but light in texture like cake. They were amazing. The 2nd and 3rd time I made these they turned out looking and tasting like cake, banana flavoured. I don't know what happened, I'm doing everything the same, but I enjoyed more the first time. Still a great recipe, I just wish I knew how to get it looking/tasting like light airy banana bread again.

    This recipe is amazing! I’m sure it is perfect as written, but seeing as I didn’t have sour cream in my fridge, I substituted 4 Tbs buttermilk powder and 1/2 c water, and these were a hit, I tell you! Holy smokes! I can’t wait to share these with everyone!
