Peanut Butter Banana Split Dump Cake

Peanut Butter Banana Split Dump Cake

The name of this dessert comes from the fact that all ingredients are literally dumped into a dish and baked – no stirring required! Somewhere between a fruit cobbler and a cake, it’s delicious and surprisingly addictive. In addition to the classic components of crushed pineapple and cherry pie filling, this version also includes peanut butter and bananas, drawing inspiration from a banana split. Serve this cake warm topped with a generous dollop of whipped cream and a maraschino cherry, and for nutty crunch, you could add a sprinkling of chopped honey-roasted peanuts.
