A rich, gooey chocolate dump cake made with chocolate cake mix, instant pudding, chocolate chips, milk, butter, and hot water. No mixing bowls required.
Do not stir the layers before baking. Use instant pudding mix, not cook-and-serve. For the best texture, serve warm. Store leftovers in an airtight container in the refrigerator for up to 3 days, or freeze for up to 2 months. Reheat individual portions in the microwave.
