About the Ingredients

Pure Pumpkin Puree

This is the star of the dish, providing a creamy texture and rich flavor that’s essential for a great pumpkin dessert.

Evaporated Milk

It adds a silky richness to the pumpkin base, enhancing the custard-like consistency that makes this cake so inviting.

Large Eggs

These bind the ingredients together and help create a tender texture, ensuring your cake is perfectly moist.

Granulated Sugar

This is the sweet foundation of the cake, balancing the spices and the natural sweetness of the pumpkin.

Brown Sugar

Packed brown sugar contributes a deeper, caramel-like flavor that complements the pumpkin beautifully.

Yellow Cake Mix

This shortcut ingredient makes the recipe incredibly easy while providing a light, fluffy texture that pairs perfectly with the pumpkin.

Rolled Oats

Adding rolled oats gives the topping a delightful crunch, enhancing the overall texture of the cake.

Chopped Pecans

These nuts add a lovely nutty flavor and extra crunch, making each bite more exciting.

Tips & Tricks

Use Fresh Pumpkin Puree

If you have the time, roasting and pureeing fresh pumpkin can elevate the flavor of your cake even more.

Don’t Skip the Resting Time

Letting the cake sit for about 15 minutes after baking helps the custard layer firm up for easier slicing.

Serve with Whipped Cream

A dollop of whipped cream or a scoop of vanilla ice cream on top takes this dessert to the next level!

Experiment with Spices

Feel free to adjust the spices to your liking or add a pinch of cardamom for an extra layer of flavor.

Pro Tips

  • Opt for Cold Butter: For a crispier topping, use cold grated butter instead of melted when drizzling over the cake mix.
  • Layering is Key: Make sure to layer the ingredients without mixing for the best texture and flavor distribution.
  • Check Your Oven: Oven temperatures can vary; keep an eye on the cake towards the end of the baking time.
  • Top with Nuts: For added crunch, sprinkle more chopped pecans or walnuts on top before baking.

Step-by-Step Instructions

Preheat and Prepare

Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or nonstick spray to prevent sticking.

Mix the Pumpkin Base

In a large bowl, whisk together the pure pumpkin puree, evaporated milk, eggs, both sugars, and spices until the mixture is smooth and silky.

Layer the Goodness

Pour the pumpkin mixture evenly into your prepared dish, spreading it out to look like a luscious pumpkin pie batter. Sprinkle the dry yellow cake mix evenly over the top, ensuring not to stir.

Add Texture

Evenly sprinkle the rolled oats and chopped pecans over the cake mix layer to create a delightful crunch on top.

Drizzle and Bake

Pour melted butter evenly over the top to ensure most of the dry mix gets covered. Bake for 50-60 minutes until the top is golden brown and the edges are bubbling slightly.

Delicious Variations

Chocolate Chip Pumpkin Dump Cake

Incorporate chocolate chips into the pumpkin mixture for a decadent twist that chocolate lovers will adore.

Apple Pumpkin Combo

Add diced apples to the pumpkin mixture for a fruity surprise that pairs beautifully with the spices.

Gluten-Free Option

Swap the yellow cake mix for a gluten-free variety to make this dessert accessible for everyone!

Ingredients

Instructions

  1. 1 Preheat and Prepare: Preheat your oven to 350°F (175°C). Grease a 9x13-inch baking dish with butter or nonstick spray.
  2. 2 Mix the Pumpkin Base: In a large bowl, whisk together pumpkin puree, evaporated milk, eggs, granulated sugar, brown sugar, and all the spices until smooth and silky.
  3. 3 Layer the Goodness: Pour the pumpkin mixture evenly into the prepared dish — it should look like pumpkin pie batter. Sprinkle the dry yellow cake mix evenly over the top. Don’t stir.
  4. 4 Add Texture: Evenly sprinkle rolled oats and pecans (if using) over the cake mix layer.
  5. 5 Drizzle and Bake: Pour melted butter evenly over the top, making sure most of the dry mix gets some coverage. For an extra crisp top, use cold grated butter instead of melted.
  6. 6 Bake to Golden Perfection: Bake for 50-60 minutes, until the top is golden brown and the edges bubble slightly. The center should be mostly set (like pumpkin pie) but still soft.
  7. 7 Cool and Serve: Let it rest for 15 minutes before slicing — this helps the custard layer firm up. Serve warm, topped with whipped cream or vanilla ice cream.

Chef's Note

Store leftovers in the refrigerator for up to 3 days. This dump cake can be made a day in advance; simply reheat before serving. For a healthier option, consider using maple syrup instead of some of the sugar.
