This small pumpkin dump cake is made from scratch with a spiced pumpkin filling and a buttery homemade topping. Baked until golden and crisp, it’s the perfect fall dessert for one or two.
Preheat oven to 350°F (175°C). Grease a 5x5-inch baking dish.
Make the Pumpkin Layer
In a medium bowl, mix pumpkin puree, milk, sugar, cinnamon, nutmeg, and allspice. Stir in the egg until blended.
Pour mixture into the prepared dish.
Make the Cake Topping
In a small bowl, whisk flour, sugar, and baking powder.
Sprinkle evenly over the pumpkin filling.
Place the dish on a rimmed baking sheet. Top with butter and sprinkle with nuts, if using.
Bake for 40 to 45 minutes, until the topping is golden and crisp.
Serve warm, either spooned onto a plate or straight from the dish.
Notes
Pumpkin Puree: Always use pure pumpkin puree, not pumpkin pie filling, to control sweetness and flavor.
Cooling Time: Let the cake cool for at least 15 minutes before serving. The filling is very hot straight from the oven, and cooling helps the flavors meld.
Baking Dish Placement: Set the baking dish on a rimmed sheet pan to prevent spills in the oven.
To make a larger pumpkin dump cake, double the ingredient amounts and use either two 5x5-inch baking dishes or one 6x8-inch baking dish.
