Banana Cake with Browned Butter Frosting

Jump To Recipe
A moist, delicious cake full of banana flavor and topped with a divine browned butter frosting.

 I don’t think I’ve made so many sweets and treats in my life than over the past week. We celebrated my husband Kale’s birthday 4 days after Kallen’s birthday, so there’s been ridiculous amounts of sugar running through our family’s bloodstream.

It’s been good and bad, all at the same time. Good for my taste buds and bad for my thighs. Good for the smiles on my birthday boys’ faces, and bad that my kids have been on a sugar high for a week. Emma was running so fast in our hallway the other night, she ate the wall. Literally. She had paint in her mouth, and a nice little bump on her chin to prove it. :/

I’ve had a pile of bananas sitting on my counter for a week. Who’s going to eat a nice, healthy banana when you’ve got mounds of cake in the fridge!? I thought I better make one last treat with them… ya know, so they didn’t go to waste. 😉

Banana Cake it was. It was moist, delicious and divine. I would serve this for a dessert or even for a brunch. When you taste it, you might even eat it for breakfast. It’s that good!

  1. Oh, Emma! That is sad but funny that she really ate the wall:) I got some bananas waiting to be used as well, so I better get going on this cake! Yum!

  2. Awe poor baby girl!!! Sugar does give you that crazy rush that makes you want to run up and down hallways screaming at the top of your lungs…not that my kids have ever done that:-)

  5. i made the cake last night and frosted it this morning. it kept tearing the top up…was the cake supposed to still be warm when frosting it? regardless, this is SO good! i am taking it to three different people because after i had a piece, i knew it’d be trouble in my kitchen if i didn’t get it out of here! 🙂 thanks so much!
