This pumpkin dump cake combines the beloved flavors of pumpkin pie with the convenience of a dump cake. The magic happens as the cake mix creates a golden, buttery crust on top of the creamy pumpkin layer, making it the perfect fall dessert without any fussing over pie crust.
I first discovered this recipe when hosting my first Thanksgiving as a newlywed. My mother in law requested pumpkin pie but I was terrified of making pie crust. This dump cake saved the day and has since become our family's most requested fall dessert.
Ingredients
- Pumpkin purée: Provides the foundation for this dessert choose 100% pure pumpkin not pumpkin pie filling
- Evaporated milk: Creates richness and creaminess that regular milk cannot match
- Eggs: Bind everything together and help create that custard like texture underneath
- Sugar: Balances the natural earthiness of pumpkin use light brown sugar for deeper flavor if desired
- Cinnamon, nutmeg, ginger, and salt: Create that classic pumpkin spice profile use freshly grated nutmeg for best flavor
- Yellow cake mix: Forms the magical crispy topping look for butter recipe cake mix for extra richness
- Butter: Transforms the cake mix into a golden crumbly crust use unsalted so you can control the salt level
- Pecans: Add delightful crunch and nutty flavor toast them lightly before adding for enhanced flavor
Step-by-Step Instructions
- Prepare Your Base:
- Whisking the pumpkin mixture until perfectly smooth is crucial. Take your time here to eliminate any lumps from the pumpkin purée or evaporated milk. The mixture should have the consistency of a thick custard when properly combined. I find that a wire whisk works better than a fork for achieving the silky texture needed.
- Create The Foundation:
- Pour the pumpkin mixture into your prepared baking dish ensuring an even layer. Use a spatula to spread it to all corners of the pan. The layer should be approximately 1 inch thick and completely level to ensure even baking.
- Add The Magic Layer:
- Sprinkle the dry cake mix evenly over the pumpkin layer using your fingertips to break up any large clumps. Aim for complete coverage with no gaps or overly thick spots. The even distribution of cake mix ensures a consistent topping texture.
- Create The Golden Crust:
- Drizzle the melted butter in thin streams over the entire surface working methodically from one end to the other. Cover as much of the cake mix as possible as any dry spots will remain powdery after baking. Two sticks of butter might seem excessive but trust me its necessary for that perfect golden crust.
- Add Texture And Flavor:
- If using pecans scatter them evenly across the top. Press them in gently so they adhere to the butter soaked cake mix. This ensures they toast properly rather than burning during the long bake time.
- Bake To Perfection:
- Bake until the top is deeply golden and a toothpick inserted into the center comes out mostly clean. The pumpkin layer underneath will still have some moisture similar to pumpkin pie. Watch carefully in the last 10 minutes as the nuts can burn if left too long.

The first time I made this cake I accidentally used salted butter and was worried it would ruin the dessert. Instead the slight salty edge actually enhanced the sweet pumpkin flavor creating an addictive contrast that my family now considers essential. Sometimes the best cooking discoveries come from mistakes!
Storing Your Pumpkin Dump Cake
After serving this delicious pumpkin treat cover any leftovers with plastic wrap and refrigerate for up to 4 days. The texture does change slightly as it chills with the cake topping becoming less crisp but many people including myself actually prefer the flavor after it has had time to meld overnight. For longer storage you can freeze individual portions wrapped tightly in plastic wrap and then foil for up to 3 months. Thaw overnight in the refrigerator before reheating gently in the microwave.
Making It Your Own
This recipe welcomes customization to suit your personal taste. Try using a spice cake mix instead of yellow for an extra dimension of warmth. White cake mix works beautifully too creating a more subtle canvas for the pumpkin flavor to shine. For the adventurous baker try adding a teaspoon of espresso powder to the pumpkin mixture it mysteriously enhances the pumpkin flavor without tasting like coffee. Another delicious variation includes folding chocolate chips into the pumpkin layer before adding the cake mix creating pockets of melty chocolate throughout.
Serving Suggestions
While this dump cake is delicious on its own it reaches new heights with thoughtful accompaniments. Serve warm with a scoop of vanilla bean ice cream that slowly melts into the crevices of the cake. For a lighter option freshly whipped cream with just a touch of maple syrup creates the perfect counterpoint to the warm spiced cake. If serving for brunch consider offering alongside a strong cup of coffee with notes of caramel or chocolate. For an extra special touch drizzle individual servings with warm salted caramel sauce or a dusting of cinnamon sugar just before bringing to the table.
The Origins Of Dump Cake
The humble dump cake has been a staple of American home baking since the mid 20th century coinciding with the rise of packaged cake mixes. This style of dessert embodies the practical ingenuity of home cooks who sought to create delicious treats with minimal effort and readily available ingredients. The beauty of dump cakes lies in their forgiving nature simply layer dump and bake. This pumpkin variation likely emerged as bakers looked for alternatives to traditional pumpkin pie especially for those intimidated by making pie crust from scratch. Today dump cakes remain popular not just for their ease but for their comforting homestyle quality that brings people together around the table.
Recipe FAQs
- → Can I use homemade pumpkin purée instead of canned?
Yes, you can substitute homemade pumpkin purée. Just ensure it's well-drained to avoid excess moisture that could affect the cake's texture. For best results, strain homemade purée through cheesecloth for several hours before using.
- → How do I store leftover pumpkin dump cake?
Store leftovers covered in the refrigerator for up to 5 days. The cake contains dairy and eggs, so refrigeration is necessary. Allow it to come to room temperature before serving, or warm individual slices briefly in the microwave.
- → Can this dessert be made gluten-free?
Absolutely! Simply substitute the regular cake mix with your favorite gluten-free yellow cake mix. The other ingredients are naturally gluten-free, but always check product labels to confirm.
- → How do I know when the dump cake is fully baked?
The cake is done when the top is golden brown and the center is set but still slightly jiggly, similar to pumpkin pie. Insert a knife near the center - it should come out mostly clean with a few moist crumbs.
- → Can I make this dessert ahead of time?
Yes, this dessert is perfect for making 1-2 days ahead. Prepare and bake as directed, then cool completely, cover, and refrigerate. Bring to room temperature before serving or warm slightly in a 300°F oven for about 15 minutes.
- → What can I use instead of pecans for a nut-free version?
For a nut-free alternative, try crushed gingersnap cookies, graham cracker crumbs, or pepitas (pumpkin seeds). You can also simply omit the nuts entirely - the cake will still be delicious with just the butter and cake mix topping.
