Quick One-Pan Creamy Pumpkin Dump Cake for Autumn
Dump cake is the most self-explanatory recipe category in existence. You dump ingredients into a pan. You do not mix them. The oven handles everything else. What comes out is a dessert that is simultaneously a cake and a pudding and a crumble — with a crispy, buttery, slightly crunchy top from the unmixed cake mix and a gooey, creamy, pumpkin-and-cream-cheese filling underneath that tastes like the best parts of pumpkin pie without the effort of making a crust.
This version adds a cream cheese layer — sweetened cream cheese spread between the pumpkin filling and the cake mix topping — that produces a cheesecake-adjacent richness in the middle of the dessert that makes it specifically more interesting than a plain pumpkin dump cake. The cream cheese layer melts slightly during baking and creates pockets of tangy, rich creaminess throughout the pumpkin filling. It is the addition that makes people say “wait, what is that layer?” after the first bite and then eat a second piece to investigate.
One pan. Six ingredients. No mixing. Forty minutes. This is the autumn dessert you make when you need something genuinely impressive that requires virtually no effort to produce — and this recipe is that thing, with complete honesty about how little work it involves.
What Makes a Dump Cake Work
The technique — dumping dry cake mix over a wet filling without mixing — works because the butter poured over the dry cake mix gradually melts during baking and hydrates the cake mix from above, while the wet filling beneath provides steam that hydrates it from below. The middle of the cake mix layer absorbs moisture from both directions and cooks into something between a cake and a crumble. The surface, which receives only the butter from above and the direct oven heat, stays dry and crunchy. The edges, where the filling is closest to the surface, become slightly gooier where the filling bubbles up through the cake layer.
The result is three textures in one pan — crispy on top, cakey in the middle, gooey at the bottom — from a preparation that involves no mixing, no bowl, and no technique more complex than pouring things in the right order.

What You Need
For the pumpkin filling layer:
- Canned pumpkin purée: 2 cans (15 oz / 425g each) — pure pumpkin, not pumpkin pie filling; the filling is already sweetened and spiced in this recipe
- Sweetened condensed milk: 1 can (14 oz / 397g) — the sweetener and the creaminess of the pumpkin layer; produces a pumpkin filling that is richer and more custardy than one made with regular sugar
- Large eggs: 2 — the binding element that sets the pumpkin filling during baking so it becomes custard-like rather than just warmed pumpkin purée
- Pumpkin pie spice: 2 teaspoons — or make your own: 1 teaspoon cinnamon, 1/2 teaspoon ginger, 1/4 teaspoon nutmeg, 1/4 teaspoon allspice
- Fine sea salt: 1/2 teaspoon — in the pumpkin layer; the salt that makes the spiced pumpkin taste specifically savoury-sweet rather than sweet-only
- Vanilla extract: 1 teaspoon
For the cream cheese layer:
- Full-fat cream cheese, softened: 8 oz (225g) — room temperature; it needs to be spreadable
- Powdered sugar: 1/3 cup (40g)
- Vanilla extract: 1/2 teaspoon
For the dump cake topping:
- Spice cake mix or yellow cake mix: 1 box (15.25 oz / 432g) — spice cake mix produces a more autumnally spiced, cinnamon-forward topping that matches the pumpkin filling; yellow cake mix produces a more neutral, buttery topping that lets the pumpkin filling be the dominant flavour; both are excellent, choice depends on how much spice you want
- Unsalted butter, cut into thin slices: 3/4 cup (170g) — enough to cover the surface of the cake mix when arranged in a single layer; the butter melts over the dry cake mix and hydrates it during baking
For serving:
- Vanilla ice cream or whipped cream — the cold dairy against the warm, gooey pumpkin dessert is not optional
- Extra cinnamon for dusting
- Caramel sauce drizzle
- Toasted pecans

How to Make It
- Preheat the oven to 350°F (175°C). Grease a 9×13 inch baking dish with butter or cooking spray.
- Make the cream cheese layer: beat the softened cream cheese, powdered sugar, and vanilla extract together with a fork or hand mixer until smooth. Set aside. This is the only mixing in the recipe.
- Make the pumpkin layer: whisk the pumpkin purée, condensed milk, eggs, pumpkin pie spice, salt, and vanilla together in a bowl until smooth and uniform. Pour into the prepared baking dish and spread to the edges in an even layer.
- Drop spoonfuls of the sweetened cream cheese mixture over the pumpkin layer — 8 to 10 dollops distributed across the surface. Use a knife or the back of a spoon to gently swirl the cream cheese into the pumpkin in a rough marble pattern. Do not over-swirl; you want distinct pockets of cream cheese throughout rather than a fully incorporated mixture. The cream cheese should be visible as lighter streaks against the orange pumpkin filling.
- Open the cake mix box and pour the dry cake mix evenly over the top of the pumpkin and cream cheese layer. Distribute with your hands if needed to create an even, level surface. Do not stir. Do not mix it into the filling below. Leave it as a dry, powdery layer on the surface.
- Arrange the butter slices in a single layer over the dry cake mix, covering as much of the surface as possible. The butter does not need to cover every single millimetre — the cake mix closest to the edges where butter is not present will stay slightly drier and crunchier, which is actually desirable for textural variation.
- Bake at 350°F for 40 to 45 minutes until the top is golden brown across the entire surface and the edges of the pumpkin filling are visibly bubbling up around the sides. The center should look set — not jiggly — when the pan is gently moved. If the top is browning too quickly before the center is set, tent loosely with foil.
- Cool for at least 15 minutes before serving — the pumpkin layer needs this time to firm from very soft to slightly set. Serve warm, directly from the pan, with vanilla ice cream or cold whipped cream over each scoop.
Pumpkin dump cake alongside our Warm Apple Cider Recipe is the autumn entertaining combination that requires almost no effort and produces the most specifically seasonal table possible — the warm, spiced, golden dump cake from the oven and the warm, spiced, apple-fragrant cider in mugs alongside, and suddenly the gathering feels planned and intentional even when both things took under an hour from start to finish. This is the hosting secret that autumn reliably provides.
The No-Mix Rule and Why the Butter Coverage Matters
Not mixing the cake mix into the filling is the entire technique of dump cake, and the instruction that first-time makers most want to violate — the dry powder sitting on top of the wet filling looks wrong in a way that is difficult to trust before you have seen the result. Trust it. The reason it works is that mixing the cake mix into the filling produces a uniform wet batter that bakes into a uniform cake — which is a fine outcome but not the three-textured, crispy-gooey-cakey result that makes dump cake specifically worth making. The unmixed dry layer on top is what produces the crispy surface. The steam rising from the wet filling below is what produces the cakey middle. The unmixed, undisturbed separation is the entire structural principle.
Butter coverage matters because any dry cake mix not reached by the melting butter stays powdery and uncooked rather than becoming the golden, crispy-cakey topping the recipe produces where the butter does reach. Complete butter coverage — the 3/4 cup of sliced butter arranged as a single layer across the surface — is what produces a uniformly golden top. Insufficient butter produces a patchy top with uncooked cake mix powderiness in the uncovered spots. If you run short on butter, a tablespoon of melted butter drizzled over the gaps fills the coverage without requiring more sliced butter.
What to Serve This With
Vanilla ice cream is the only correct accompaniment. The cold ice cream against the warm, gooey dump cake produces the hot-cold contrast that makes this dessert specifically excellent in a way that room-temperature whipped cream does not quite replicate — though room-temperature whipped cream is also very good and produces a softer, less dramatic contrast. Serve both if the occasion allows.
A drizzle of caramel sauce over the ice cream and the dump cake simultaneously — connecting the two with a sweet, slightly bitter caramel thread — is the addition that makes this look like a constructed dessert rather than a scoop-from-the-pan situation. The caramel, the cinnamon dusting, and the pecans together are the three toppings that take this from potluck dessert to something you would pay for at a restaurant. They take two minutes and change the visual completely.
For an autumn dessert table, this dump cake alongside our Pumpkin Bars with Cream Cheese Frosting covers both the warm-from-the-oven shared pan format and the individual bar format on the same table — two pumpkin desserts that share the cream cheese direction but deliver it in completely different formats, making the spread feel considered rather than repetitive.
Variations That Are All Straightforward
Apple Dump Cake: Replace the pumpkin filling with 2 cans of apple pie filling (or 4 cups of fresh apples tossed with sugar, cinnamon, and cornstarch). Skip the cream cheese layer or keep it — sweetened cream cheese with apple pie filling is excellent. Use spice cake mix or yellow cake mix as the topping. The apple version is the most classic dump cake direction and the one most familiar to people who have encountered dump cakes before. Serve warm with vanilla ice cream and a drizzle of caramel.
Peach Dump Cake: Replace the pumpkin filling with 2 cans of sliced peaches in juice (not syrup — the heavy syrup version is too sweet and too wet). Skip the cream cheese layer or use it. Use yellow cake mix. The peach version is the summer dump cake — lighter, fresher, and the one to make when autumn has not yet arrived but you want something effortless and crowd-pleasing. Particularly good with fresh whipped cream and fresh mint over the top.
Chocolate Pumpkin Dump Cake: Use chocolate cake mix instead of spice or yellow cake mix. Add 1/2 cup of semi-sweet chocolate chips scattered over the cream cheese layer before the cake mix goes on. The chocolate-pumpkin combination is the most unexpected and frequently the most requested variation — the chocolate cake topping against the spiced pumpkin filling and the cream cheese is richer, darker, and more complex than the original and produces a dump cake that tastes specifically of autumn in a chocolate context.
Make It Lighter: Replace the sweetened condensed milk with 1 cup of evaporated milk mixed with 3 tablespoons of maple syrup and 2 tablespoons of brown sugar. Replace the full-fat cream cheese with reduced-fat cream cheese and reduce the powdered sugar to 2 tablespoons. Use 1/2 cup of butter rather than 3/4 cup. The lighter version is approximately 310 calories per serving rather than 445 and retains the three-texture structure and the pumpkin-cream cheese character without the full richness of the original.

These values reflect the full recipe with spice cake mix, condensed milk, full-fat cream cheese, and 3/4 cup of butter — an honest account of what a generous dump cake serving contains. The 62 grams of carbohydrate comes from the cake mix, the condensed milk, and the pumpkin; the 20 grams of fat from the butter and cream cheese. At 445 calories per serving, this is a dessert rather than a snack, and it earns every calorie in the texture and flavour of the finished result. With vanilla ice cream added, each serving reaches approximately 600 calories — a complete, indulgent, absolutely worth-it autumn dessert portion.
Storing and Reheating
Store covered in the baking dish in the fridge for up to 4 days. The crispy top softens during refrigeration as the moisture from the pumpkin filling migrates upward — a soft-topped dump cake from the fridge is still completely delicious, just differently textured than the fresh version. To restore some of the crunch, reheat individual portions at 325°F for 10 to 12 minutes rather than the microwave — the oven heat re-crisps the top layer in a way the microwave cannot. The microwave reheats faster and produces a warm, gooey, uniformly soft dump cake that is comforting in its own way.
This dish does not freeze particularly well — the pumpkin custard layer can become slightly watery on thawing and the cake topping loses its textural differentiation during the freeze-thaw cycle. Make and eat within 4 days. Given the 12-serving yield, this has never proven to be a constraint at any gathering where dump cake has appeared.
The Mistakes That Barely Qualify as Mistakes
Mixing the cake mix into the filling — the instinct that is hardest to resist on first attempt — produces a cake-like result rather than the three-textured dump cake the recipe is designed to make. The dry layer stays dry for a reason. Pour it on. Walk away. Let the oven figure it out.
Using pumpkin pie filling instead of pure pumpkin purée produces a dump cake that is sweeter and more strongly spiced than the recipe intends — the condensed milk already provides sweetness and the pumpkin pie spice already provides the spicing. Pumpkin pie filling added on top of those layers produces something that can taste aggressively spiced and one-dimensionally sweet. Pure pumpkin purée. Check the can label before opening.
Not leaving enough cooling time produces a pumpkin layer that is still liquid underneath the cake topping and runs when the pan is scooped — the filling needs at least 15 minutes to firm from very soft to scoop-able. A dump cake served at 5 minutes from the oven looks like a sauce situation rather than a dessert situation. Wait the 15 minutes. The texture difference between 5 minutes and 15 is significant and worth the wait.

Ingredients
How to Make
Preheat oven to 350°F / 175°C. Grease a 9×13 inch baking dish with butter or cooking spray.
Beat softened cream cheese, powdered sugar, and ½ teaspoon vanilla together with a fork or hand mixer until smooth. Set aside.
In a separate bowl, whisk pumpkin purée, sweetened condensed milk, eggs, pumpkin pie spice, salt, and 1 teaspoon vanilla until smooth and uniform. Pour into the prepared dish and spread evenly.
Drop 8 to 10 spoonfuls of the cream cheese mixture over the pumpkin layer. Gently swirl with a knife into a rough marble pattern (do not fully mix).
Pour the dry cake mix evenly over the top of the pumpkin and cream cheese layer. Spread gently to cover. Do not stir.
Arrange thin butter slices in a single layer over the dry cake mix, covering as much surface as possible.
Bake at 350°F for 40 to 45 minutes, until the top is golden brown and the edges bubble. Tent loosely with foil if the top browns too quickly.
Cool for at least 15 minutes to firm slightly. Serve warm with vanilla ice cream, whipped cream, caramel sauce, or pecans.
