I think you would say this is somewhat similar to a dump cake, but it is made in the crockpot which can be a real convenience when the oven is full of the main course. Two tablespoons of pummpkin pie spice may seem like a lot but it is what gives incredible flavor to this dessert. This dessert is delicious any autumn day or winter holiday. Note that standing time is not figured into the timing of this recipe. Recipe from BH&G.
