Best Banana Cake with Peanut Butter Frosting

Photo: Once Upon a Cutting Board

It takes the humble banana cake to a new level of deliciousness – and let me tell you that the frosting is just sensational.

Combining a moist banana cake made with sour cream, a peanut butter frosting and an additional second frosting made from cream cheese, this is a banana layer cake to treasure.

I always feel there’s is something delightful childish about using peanut butter in cake recipes or indulging in a great peanut butter frosting.

I also don’t tend to opt for peanut butter sandwiches these days, but this cake allows you to rediscover the utter joy of a banana and peanut butter sandwich, in a slightly more grown-up way.
