Banana Split Dump Cake is the perfect substitute for a real banana split, with no melting involved! Make this sundae-inspired dessert in less than an hour.
Spread the crushed pineapple and the strawberry pie filling into the bottom of a 9x13-inch baking dish.
Sprinkle the cake mix evenly over the first two layers.
Slice very thin pats of butter and spread over the entire top of the dry cake mix. Cover as much of the cake mix as possible. Hint: cold butter is much easier to slice and to maintain square pats for covering the top of the dump cake.
Sprinkle coconut and chopped walnuts over the top of the butter.
Bake for 40 minutes or until the topping is browned and the filling is bubbling around the edges. The coconut and walnuts should be evenly toasted but not burnt.
Allow dump cake to cool for at least 30 minutes. Slice bananas and space over the top of the dump cake just before serving.
