One day my aunt was complaining about how my uncle would always buy bananas with the idea of having peanut butter and banana sandwiches, but never actually get around to making them before the bananas went bad. A couple days later I was looking at a bunch of overripe bananas on my counter… and got inspired to make a peanut butter banana cake. It turned out to be such a treat I immediately made another one to share with my aunt and uncle!

For the Frosting – whisk the sugar, salt, and yogurt together until the sugar is completely dissolved, then whisk in the peanut butter powder.
Spread the Frosting on the cooled cake.
