I will never let over ripe banana’s go to waste, there is always a new recipe to create and these banana cake squares with frosting are so fluffy and delicious! Sometimes I just throw things in a bowl and hope for the best, I won’t lie..it can be a disaster sometimes, although my husband will still eat my fails lol, he will eat anything! ๐Ÿ˜‰ But sometimes the result makes me so happy I winged it.. These tasty baked up treats are just 4 smart points each and I highly recommend trying them..

  • 1 egg
  • 2 Tbsp egg whites I use from the carton
  • 1/4 cup brown sugar
  • 2 medium banana's mashed, about 1 cup
  • 1/2 cup 0% plain greek yogurt non greek will work as well
  • 1/3 cup unsweetened apple sauce
  • 1 tsp vanilla
  • 1.5 cups flour
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 3/4 Tbsp butter melted
  • 2 Tbsp brown sugar
  • 3/4 Tbsp milk
  • 1/4 cup icing sugar


  • Preheat oven to 375F, spray a 9 inch baking dish with some cooking spray.
  • In a bowl beat together your egg, egg whites and brown sugar. Add in mashed banana, yogurt, apple sauce and vanilla and mix well.
  • Stir in flour, baking powder & soda and pour batter into your baking dish.
  • Bake in oven for 28 minutes.
  • Meanwhile make your frosting, mix melted butter and brown sugar together, stir in milk then add icing sugar and stir till creamy. It does not give you a lot of icing but enough to cover squares. Store frosting in fridge till ready to use.
  • Let squares cool before removing from dish, spread with frosting and cut into 16 squares, 4 down and 4 across.
  • Makes 16 squares at 4 personal points or 4 smart points each on blue, green & purple (2 points plus, old WW program) *Store in a sealed container, best stored in the fridge. *Note.. If not needing all the squares at once feel free to frost them individually as the frosting will keep better in a dish and not on squares. You can leave the icing of and these squares would be 2 smart points each.

  1. How are you tracking these in WW? Iโ€™ve typed everything Banana in and nothing even close matches. Just curious what others do.

      Hi there, you can’t find my recipes in the App, just like any other recipes from other food bloggers.. (although that would be cool ha!) you need to enter it as a quick add food and input the name plus point value yourself..

  2. I just put this in the oven, I can’t wait to try it. Your recipes have helped me so much on my weight loss. I have made so many of your dishes. You make it easy with the points there on the recipe. I make at least 1 a week. They are easy and tasty and even my kids and husband love them. Just wanted to say Thank You! Thank You! Please keep doing what you do!!!!

      Thank you so much for your kind words Evelyn, I really hope you enjoyed the banana squares ๐Ÿ™‚

  3. This looks delicious! I just stumbled across a link to your site from a WW group on FB.

    I was going to ask what size baking dish you used, and realized when skimming I’d missed it. So thanks for sharing and giving all the info!! Can’t wait to make it.

  4. 5 stars
    Hi your recipe called for a nine inch dish,is that nine inch square or can I use an 8 x8 dish, thanks

    • Drizzle Reply

      Hi, I use a 9 inch square dish, you can use 8 inch your pieces will just be a little smaller..

  5. This might be a dumb question but what is icing sugar? Is that just powdered sugar? Thank you in advance!

  6. This is so good! I made it without the frosting for my boyfriend who must have some sort of sweet/quick bread every morning and we both loved it. So moist and fluffy. Great job!

      Thanks! So glad you both enjoyed it.. I too loved it even without the frosting ๐Ÿ™‚

    • Drizzle Reply

      Hi, yes post says 2 points minus the icing ๐Ÿ™‚

        Your recipe calls for 3/4 of a tbsp of butter and milk. Are those typos? Is it supposed to be a cupโ€”not tbsp?

        • Drizzle Reply

          No it is not a typo, you only need a little to make the frosting.. it is indeed 3/4 of a Tbsp

    I only have self rising flour… Do I still follow the recipe as it is or do I make changes???
    BTW- I am excited to find your site! My wife and I are on WW and the variety of your recipes is a welcomed addition!;

    • Drizzle Reply

      Hi Willis, I’m so glad you found me and I hope you both enjoy the recipes, self rising flour has baking powder in it but if I was using it I would likely still add a bit

  8. Does the calorie count include the frosting? Thank you for all your wonderful recipes.

  9. Good morning! I had some very ripe bananas and decided to make this and must say, Delish! This was so easy to make, I had everything on hand. Only change I made was to use Lankato Golden monkfruit sweetener instead of brown sugar and this made recipe for cake only 1 point!! Yay! I didn’t make the frosting but I saved that as an optional recipe for another time or maybe a different cake. (As a separate recipe in WW recipe builder, frosting was only 1 point!)
    This is, I think, the 5th recipe I’ve tried and so far, everyone has been just great!! Thank you for all you do, it’s so nice to be able
    to ‘indulge’ and still lose weight!!

      Hi Michael, I am so glad you enjoyed the banana squares, that is awesome that they went down to 1 point using the monkfruit, thanks for sharing.. I hope you continue to enjoy the recipes ๐Ÿ™‚

  10. This was very good. I used swerve sugar replacement for the brown and confectioners sugar. It was great, you couldn’t even tell it was sugar free. This is a keeper!
