Ingredient Breakdown
Pumpkin Puree (1 can, 15 oz): The heart of the recipe. Pumpkin puree adds moisture, natural sweetness, and that classic fall flavor we all love. Use pure pumpkin not pumpkin pie filling to control the spice balance. This ingredient makes the dessert nutrient-rich and perfect for healthy fall recipes.
Evaporated Milk (1 can, 12 oz): Adds creaminess and helps create a custard-like consistency in the pumpkin layer. It gives the cake a smooth, velvety texture without being heavy. For a dairy-free version, try oat milk or coconut milk for a vegan-friendly dessert swap.
Eggs (3 large): Eggs are essential for structure. They bind the pumpkin mixture and ensure the filling sets properly while baking. Plus, they add richness for a satisfying bite.
Granulated Sugar (1 cup): Enhances the natural sweetness of the pumpkin and ensures the filling caramelizes beautifully in the oven.
Brown Sugar (½ cup): Adds depth, moisture, and a subtle molasses note that pairs perfectly with warm spices. It’s one of the secret ingredients that makes this family comfort dessert so addictive.
Cinnamon (1 tsp): The classic fall spice. It adds warmth and fragrance to every bite.
Nutmeg (½ tsp): Contributes a slightly nutty, sweet aroma that complements the pumpkin flavor beautifully.
Ginger (½ tsp): Adds a hint of spice and brightness to balance the sweetness.
Cloves (¼ tsp): A little goes a long way! This spice deepens the flavor, giving the dessert that nostalgic holiday feel.
Yellow Cake Mix (1 box): The magic ingredient that makes this recipe so easy! Instead of mixing dry ingredients, you “dump” the cake mix on top of the pumpkin layer. As it bakes, it creates a sweet, buttery crust that perfectly complements the creamy filling.
Rolled Oats (1 cup): Adds a hearty, wholesome texture to the topping. The oats toast beautifully, giving the dessert a crisp, bakery-style finish. Great for those who love healthy ingredients in their desserts.
Chopped Pecans (½ cup, optional): For an extra crunch and nutty flavor. Pecans add a gourmet touch and make this feel like a bakery-worthy dessert. For nut allergies, skip them or replace with sunflower seeds for a nut-free alternative.
Melted Butter (½ cup): The key to creating that golden, buttery crust. When poured over the dry cake mix and oats, it melts into the dessert as it bakes, binding the top layer together for a delicious crumble.
Pro Tips for the Perfect Pumpkin Oatmeal Dump Cake
