What You’ll Need for Pumpkin Dump Cake

- 15 ounces pumpkin puree (1 can)
- 10 ounces evaporated milk
- 1 cup brown sugar (packed)
- 3 large eggs
- 3 teaspoons pumpkin pie spice (or substitute with 1 tsp cinnamon, 1 tsp ginger, ½ tsp nutmeg, and ½ tsp cloves)
- 15 ¼ ounces yellow cake mix (1 box)
- 1 cup crushed graham crackers (about 8 full sheets)
- ½ cup toffee pieces (Heath bar pieces work great)
- ⅓ cup chopped pecans (optional, can substitute with walnuts or omit for nut-free)
- 1 cup butter (melted, unsalted or salted both work)
- 1 cup whipped topping (optional, for serving)
How to Make Pumpkin Dump Cake
- Preheat your oven to 350°F (175°C). Lightly spray a 9 x 13 inch baking pan with nonstick cooking spray (a glass pan works best).
- In a large bowl, combine the pumpkin puree, evaporated milk, brown sugar, eggs, and pumpkin pie spice. Stir well until fully mixed and smooth.
- Pour the pumpkin mixture into the prepared baking pan, spreading it evenly.
- Sprinkle the dry yellow cake mix evenly over the pumpkin layer. Then, top with the crushed graham crackers, toffee pieces, and chopped pecans.
- Drizzle the melted butter evenly over the entire top layer. This will create a golden, crispy crust as it bakes.
- Bake for 45-50 minutes, or until the center is set and the edges are lightly browned. A toothpick inserted into the center should come out mostly clean.
- Let cool for at least 15-20 minutes before serving. For an extra treat, add a dollop of whipped topping to each slice.
Whipped Topping & Sauce Ideas
While the optional whipped topping is delicious, you can elevate your Pumpkin Dump Cake with other toppings! Try a drizzle of caramel sauce or a scoop of vanilla ice cream for a warm-and-cold contrast. For a festive touch, sprinkle extra toffee pieces or a pinch of cinnamon on top. If you’re feeling adventurous, a dollop of spiced whipped cream (add a dash of pumpkin pie spice to whipped cream) pairs perfectly!
Perfect Pairings for Serving
This dessert shines as a cozy fall treat, but it’s even better with the right accompaniments. Serve it alongside a cup of spiced chai tea or hot apple cider for a comforting combo. For a brunch twist, pair it with a pumpkin spice latte or a plate of crispy bacon to balance the sweetness. It’s also a crowd-pleaser at holiday gatherings—just add a festive garnish like a sprig of mint or a dusting of powdered sugar.
Storage & Reheating Tips
Store leftover Pumpkin Dump Cake in an airtight container in the fridge for up to 4 days. To reheat, pop a slice in the microwave for 15-20 seconds or warm it in the oven at 300°F for 5-10 minutes. For longer storage, you can freeze individual portions wrapped in plastic wrap and foil for up to 2 months. Thaw in the fridge overnight before reheating.
Easy Recipe Variations
Customize this dessert to suit your taste! Swap the yellow cake mix for a spice cake mix to double down on fall flavors. If you’re not a fan of pecans, try walnuts or skip the nuts altogether. For a chocolatey twist, replace the toffee pieces with chocolate chips. You can also use gingersnap crumbs instead of graham crackers for a spicier kick!
Time-Saving Tips for Busy Bakers
To save time, prep your dry ingredients (cake mix, graham cracker crumbs, toffee, and pecans) the night before and store them in separate containers. Use a pre-measured spice blend like pumpkin pie spice to skip measuring individual spices. If you’re in a rush, skip the whipped topping and serve it straight from the pan—it’s just as delicious!
