Pumpkin Dump Cake

Dump cakes are the kind of dessert that sound too easy to be good until you taste one. This pumpkin version builds a spiced pumpkin custard on the bottom, sprinkles a box of yellow cake mix straight over the top, and finishes with melted butter and pecans that bake into a crumbly, buttery streusel.

The magic happens as it bakes. The cake mix draws moisture from the custard below, forming a tender cake layer on top while the pumpkin custard sets into a pie-like texture underneath. No mixing the cake batter, no separate layers to assemble. Just dump, sprinkle, pour, and bake.

Evaporated milk is the traditional choice here, not whole milk or cream. It’s more concentrated and gives the custard a richer, denser texture that holds up against the cake topping.

The spice blend (cinnamon, nutmeg, cloves) is classic pumpkin pie territory, and the quantities are right for a full 13×9 pan. Don’t skimp. Underspiced pumpkin custard tastes flat.

Kitchen Tips

• Pour the melted butter evenly over the entire surface of the cake mix. Dry patches of cake mix stay powdery after baking and look and taste wrong.
• Sprinkle the pecans on BEFORE the butter so the butter saturates them. Pecans added after stay dry.
• Check at the 1-hour mark. The top should be golden brown and the edges bubbling. Add 10 minutes if the center looks wet.
• Cool at least 30 minutes before serving. Dump cake needs time for the custard to set.

Variations

• Swap pecans for chopped walnuts or a mix of both.
• Use a spice cake mix instead of yellow cake for double the warm spice flavor.
• Serve with vanilla ice cream or a dollop of sweetened whipped cream instead of Cool Whip.
