Pumpkin Dump Cake

This pumpkin dump cake is a favorite among simple recipes that taste like a celebration, especially for a season like fall.

Minimal effort in the kitchen yields warm, spiced pumpkin custard tucked beneath a buttery, crisp cake topping with toasted pecans scattered across the surface.

It’s the kind of dessert that smells like autumn the moment it slides into the oven, and it’s so easy to throw together that it’s my go-to when I want something special and seasonal without fuss.

I first made this recipe the week the leaves started changing. I had a family gathering and wanted a Thanksgiving-adjacent dessert that didn’t require pie crust drama or hours of rolling and chilling. The pumpkin and spices filled the house with comfort, the top browned golden and the telltale sizzle at the edges meant it was ready.

After one bite of these flavors: rich pumpkin, a caramel-y brown sugar note, and that buttery cake topping… well, there were no leftovers. It’s that kind of friendly, crowd-pleasing bake.

Ingredients

Here’s what to gather to make this delicous pumpkin dump cake:

• Pumpkin puree: The smooth, earthy base that gives the cake its signature pumpkin flavor
• Evaporated milk: Adds creaminess and a custard-like silkiness to the filling
• Light brown sugar: Brings caramel notes that deepen the pumpkin’s natural sweetness
• Eggs: Provide structure and help set the pumpkin layer as it bakes
• Pumpkin pie spice: The blend of cinnamon, nutmeg, ginger and cloves that defines fall baking
• Ground cinnamon: Reinforces warmth and aroma
• Yellow cake mix: The “dump” component that transforms into a crisp, buttery topping as the butter melts
• Butter (salted): Slices of butter melt through the cake mix to create the golden crust and add richness.
• Pecans: Toast as the cake bakes, adding crunch and a toasty, nutty finish
• Whipped cream or vanilla ice cream (optional): The perfect finishing touch for serving warm or slightly cooled slices

Instructions

1️⃣ Prehead and prepare

Start by preheating your oven to 350°F. Grease your 9×13-inch baking pan generously so you don’t have any of that pumpkin goodness sticking to the bottom.

2️⃣ Make the pumpkin layer

In a large mixing bowl, whisk together the pumpkin puree, eggs, evaporated milk, light brown sugar and spices until smooth. This base will look similar to a pumpkin pie filling, and it’s what gives this cake its soft, custardy bottom layer.

Pour this mixture evenly into your prepared pan. It should spread easily. If not, use a spatula to level it out.

3️⃣ Add the cake mix

Now it’s time to “dump!” Sprinkle the yellow cake mix evenly over the pumpkin layer. Resist the urge to stir. The magic of this recipe comes from keeping the layers distinct.

4️⃣ Add butter and nuts

Slice your butter into very thin pieces and arrange them evenly across the cake mix. This step ensures that every inch gets that buttery crisp texture. Scatter the chopped pecans across the top, pressing them down gently so they stick.

5️⃣ Bake

Place the pan in the preheated oven and bake for 1 hour, or until the top is golden and a toothpick inserted comes out mostly clean. The filling should be set but still a little soft in the center.

6️⃣ cool and serve

Let the cake cool for at least 15 minutes before serving. This helps the layers firm up so each slice holds together.

Serve warm with a generous dollop of whipped cream or a scoop of vanilla ice cream. The contrast of warm cake and cold cream is simply divine.

Serving suggestions

🍨 With vanilla ice cream: A warm slice with melting ice cream is pure comfort and makes the top a little more saucy.
🥄 With whipped cream: A cloud of whipped cream and an extra sprinkle of cinnamon make each serving feel elegant.
☕ With coffee or spiced tea: Serve alongside warm drinks like wassail for a full fall flavor.
🍁 For holiday dessert tables: Slice into squares and arrange on a platter with seasonal garnishes like candied pecans or a drizzle of maple syrup.

Storage + make-ahead tips

• Cool completely before covering. Store leftovers in the refrigerator for up to four days; the cake flavor often improves after a day.
• Reheat slices in a low oven (300°F) for 8–10 minutes to revive a crisp top, or microwave individual portions for 20–30 seconds if you’re in a hurry.
• Freeze for later: Wrap cooled slices tightly in plastic and foil, or store in freezer-safe containers for up to three months. Thaw overnight in the refrigerator and warm gently before serving.
• Make-ahead trick: Prepare the pumpkin layer the day before and store it covered in the pan in the fridge. When ready to bake, top with cake mix, butter, and pecans, then bake as directed.

Variations + substitutions

• Spice cake mix: Swap the yellow cake mix for spice cake mix to boost autumn flavors.
• Walnut swap: Use walnuts instead of pecans for a different nutty note.
• Maple brown sugar: Replace brown sugar with dark brown sugar and add a swirl of maple syrup for a maple-pecan twist.
• Gluten-free: Use a gluten-free cake mix and a certified gluten-free flour substitute. The texture will be slightly different but it’ll still be delicious.
• Dairy-free/Vegan: Use coconut evaporated milk and dairy-free butter, and choose a vegan cake mix to make a plant-friendly version.
• Boozy boost: Stir a tablespoon of bourbon into the pumpkin layer for a grown-up twist.

Helpful tools

• Large mixing bowl: For whisking the pumpkin custard until smooth
• 9×13 baking pan: The ideal size for even baking and layer proportions
• Rubber spatula: For smoothing the pumpkin layer before topping
• Sharp knife: For slicing butter into thin pats evenly across the top
