Banana Cake with Caramel Frosting

Sharing is caring!

The problem of what to do with the ripe bananas sitting on the counter is one that we have often at my house. Needing to use up a few, I made this moist banana cake from Cooking with Carlee.

If you have the patience, I found that this cake tasted even more wonderful on the third or forth day. So moist and the flavor was just fantastic.

I kept leftovers wrapped up on the counter. The frosting does stick to foil or cling wrap so you may want to make sure it isn’t touching the top of your cake. So very good and the kiddos absolutely loved it. Enjoy!

  1. I am always looking for recipes that use old bananas, even though I love my classic banana muffins the amount of times I end up with old bananas I definitely need a new recipe in my repertoire! Plus the caramel icing has me drooling!

  2. Hello! I am excited to try this recipe tonight. My son requested banana bread for his bday cake! So when I saw this recipe, I knew it was meant to be! We just moved to a town that is at 6500 elevation, so im just curious at what elevation you are at? And if you suggest I make changes? Thx!

    1. You are quite a bit higher up in elevation. For high altitude baking, I would recommend King Arthur Flour:

      They are my go to. In general, I find that things bake a lot faster, sometimes up to 25% faster, so keep a close eye on it. We add in another tablespoon of flour in most cake recipes as well as an extra tablespoon of liquid. Consult that webpage I linked, as you will be adding in even more since you are so high up.
