1-Follow these steps for a foolproof pumpkin dump cake. Preheat your oven to 350°F for best results. Grease a 9×13-inch baking dish. This easy 3 ingredient pumpkin dump cake base expands with extras for full flavor.

2-First Step: Prepare the Pumpkin Base Combine 29 ounces canned pumpkin puree, 12 ounces evaporated milk, 4 large eggs, 1 cup granulated sugar, and 2 teaspoons pumpkin pie spice in a large bowl. Whisk until smooth, about 2 minutes. Pour this mixture evenly into the prepared baking dish. It forms the soft, spiced foundation. For vegan adaptations, use coconut milk and flax eggs here.

3-Second Step: Add the Cake Mix Layer Sprinkle the entire box of yellow cake mix (15.25 ounces) evenly over the pumpkin mixture. Do not stir; just spread it out flat with your hands or a spoon. Pat it down gently for even coverage. This dry layer will absorb moisture during baking, creating the signature dump cake texture. Gluten-free cake mix works perfectly in this step.

4-Third Step: Top with Nuts and Butter Scatter 1 cup chopped pecans across the cake mix. Then, drizzle 1 cup melted unsalted butter slowly and evenly over everything. The butter melts into the mix, forming crispy edges and a golden top. For low-calorie, use half the butter and spray lightly with oil. Ensure full coverage to avoid dry spots.

5-Fourth Step: Bake to Perfection Bake at 350°F for 50-60 minutes. The center should set but remain slightly jiggly, like pumpkin pie. Edges will bubble and brown. Rotate the dish halfway for even cooking. If making crockpot pumpkin dump cake, layer the same way in a 6-quart slow cooker on low for 3-4 hours. Check with a toothpick; it should come out mostly clean.

6-Final Step: Cool and Serve Let cool for 30 minutes on a wire rack. Serve warm with whipped cream or ice cream. Cuts into 12-15 servings. For no bake pumpkin dump cake dessert, chill after partial bake and top with yogurt. Store leftovers as noted later. This method yields moist, flavorful results every time.
