Easy Pumpkin Dump Cake (10-Minute Prep, Big Fall Flavor)
Equipment
- 1 9×13 inch baking dish greased
- 1 Large bowl
- 1 Whisk
- 1 Measuring cups and spoons
Ingredients
Pumpkin Custard Base
- 15 oz pumpkin puree 1 can; not pumpkin pie filling
- 12 oz evaporated milk 1 can; or half-and-half; dairy-free use full-fat coconut milk
- 3 large eggs
- 0.75 cup granulated sugar or 1/2 cup white sugar + 1/4 cup brown sugar
- 2 tsp pumpkin pie spice or 1 1/2 tsp cinnamon + 1/2 tsp ginger + 1/4 tsp nutmeg + pinch clove
- 1 tsp vanilla extract
- 0.5 tsp fine sea salt
Topping
- 15.25 oz yellow cake mix 1 box; spice cake mix works great too; use gluten-free cake mix as needed
- 1 cup unsalted butter melted and slightly cooled; use dairy-free butter for dairy-free
- 0.75 cup pecans or walnuts chopped; optional
- 2 tbsp turbinado sugar optional for extra crunch
For the Pan
- Nonstick spray or butter for the pan
Instructions
Preheat and Prep the Pan
- Preheat oven to 350°F. Grease a 9×13 inch baking dish with nonstick spray or butter.
Whisk the Pumpkin Custard Base
- In a large bowl, whisk pumpkin puree, evaporated milk, eggs, sugars, pumpkin pie spice, vanilla, and salt until smooth and glossy.
Pour Into the Dish
- Pour the pumpkin mixture into the prepared pan, spreading evenly into the corners.
Add the Dry Cake Mix
- Sprinkle the dry cake mix evenly over the pumpkin layer. Aim for full coverage without big mounds for even browning.
Finish With Butter and Toppings
- Slowly drizzle melted butter evenly across the surface so most of the dry mix looks moistened. Sprinkle on nuts and turbinado sugar if using.
Bake to Golden Perfection
- Bake 50 to 60 minutes, until the top is deeply golden and the center is set with a slight jiggle. A toothpick in the topping should come out with a few moist crumbs but not wet batter.
Cool, Slice, and Serve
- Cool at least 20 minutes so the custard sets cleanly. Serve warm or at room temp with whipped cream or vanilla ice cream.

Step-by-Step Instructions to Make Easy Pumpkin Dump Cake
Preheat and Prep the Pan

Sprinkle the dry cake mix evenly over the pumpkin layer. Aim for full coverage without big mounds for even browning.
Finish With Butter and Toppings

Bake to Golden Perfection
Bake 50 to 60 minutes, until the top is deeply golden and the center is set with a slight jiggle. A toothpick in the topping should come out with a few moist crumbs but not wet batter.
Cool, Slice, and Serve
Cool at least 20 minutes so the custard sets cleanly. Serve warm or at room temp with whipped cream or vanilla ice cream.
Tips for Success
- Even coverage matters: sprinkle the cake mix in a thin, uniform layer to avoid dry patches.
- Melted butter ensures consistent browning; drizzle slowly for best distribution. Prefer classic style? Use 1 cup cold butter thinly sliced and layered over the cake mix.
- Use pure pumpkin puree. Pumpkin pie filling is pre-sweetened and will make the dessert overly sweet and soft.
- Metal pans brown faster than glass or ceramic. Start checking at 45 minutes.
- Let it rest before serving so the custard sets and slices neatly.
Variations of Easy Pumpkin Dump Cake
- Spice Cake Mix: Boost warm spice notes by swapping yellow cake for spice cake.
- Maple Brown Sugar: Replace 1/4 cup sugar with brown sugar and drizzle 2 tbsp maple syrup over the pumpkin layer.
- Cream Cheese Swirl: Dollop 6 oz softened cream cheese mixed with 1/4 cup sugar and 1 tsp vanilla over the pumpkin layer, then swirl.
- Gluten-Free: Use a 1-to-1 gluten-free yellow or spice cake mix.
- Dairy-Free: Use full-fat coconut milk in place of evaporated milk and a dairy-free butter alternative.
- Nut-Free Crunch: Skip nuts and finish with oats tossed in a little melted butter and cinnamon.
Serving Suggestions: What to Pair with Easy Pumpkin Dump Cake
- Freshly whipped cream with a pinch of cinnamon or cardamom.
- Vanilla or cinnamon ice cream and a drizzle of warm caramel.
- Toasted pecans and a sprinkle of flaky sea salt for contrast.

Storage & Reheating Instructions
- Refrigerate: Cool completely, cover, and refrigerate up to 4 days.
- Reheat: Warm slices at 300°F for 10 to 12 minutes, or microwave 20 to 30 seconds until just heated.
- Freeze: Wrap tightly and freeze up to 2 months. Thaw overnight in the fridge, then warm briefly to refresh the topping.
Memories Made Around the Table
This was our go-to treat after Saturday pumpkin patches. Little hands sprinkled cake mix while I drizzled butter, and we would lean over the oven door waiting for that cinnamon-spice aroma to fill the kitchen.
FAQs
Can I make Easy Pumpkin Dump Cake ahead of time?
Yes. Bake, cool, and refrigerate up to 24 hours. Reheat gently at 300°F for 10 to 12 minutes or serve chilled with whipped cream.
Why is my topping still powdery in spots?
Those areas likely did not get enough butter. Drizzle melted butter slowly to moisten the surface. If needed, spritz dry spots with a little extra melted butter halfway through baking.
Can I use pumpkin pie filling?
Skip it. Pumpkin pie filling is pre-sweetened and spiced, which throws off the balance and texture. Use pure pumpkin puree for best results.
How do I halve the recipe?
Use an 8×8 or 9×9 inch pan, halve all ingredients, and bake 40 to 50 minutes, checking early for doneness.
Is there an egg-free option?
For a similar set, whisk 2 tbsp ground flax with 6 tbsp water and let gel, then add 2 tbsp cornstarch to the pumpkin mixture. Use coconut milk and dairy-free butter for a fully vegan version. Texture will be slightly softer but still delicious.
Final Thoughts
If you crave a low-effort dessert with high fall payoff, this Easy Pumpkin Dump Cake is the cozy keeper you will make on repeat. Grab a spoon, add a swoop of whipped cream, and enjoy every warm, spiced bite.
