Notes

This dump cake is perfect served warm with vanilla ice cream. For variations, try milk chocolate, dark chocolate, or butterscotch chips. Add chopped pecans or walnuts for extra nuttiness. Reese's Pieces or peanut butter cups can also be added for an extra peanut butter punch. A pinch of cinnamon or cayenne pepper can add warmth.
