Pumpkin Dump Cake with Sweetened Condensed Milk is one of those recipes that feels like a warm hug on a chilly day. It’s super simple, requires minimal effort, and yet delivers a rich, comforting dessert that’s perfect for fall or any time you want a cozy treat. If you’re a fan of pumpkin and easy baking, this one’s going to be a keeper.

Why You Should Try This Dump Cake Recipe

This recipe is a lifesaver when you want something sweet without spending hours in the kitchen. The sweetened condensed milk adds a creamy richness that makes the pumpkin flavor pop beautifully. Plus, dump cakes are famously easy because you literally dump everything into a pan and bake. No fancy mixing bowls or complicated steps—just straightforward deliciousness.

I’ve made this cake dozens of times for family gatherings, and it always disappears fast. If you’re looking for a dessert that feels homemade but doesn’t require a pastry degree, this fits the bill perfectly.

Ingredients You’ll Need

Here’s what I gather on my shopping list every time I make this cake:

1 can (15 oz) pumpkin puree
1 can (14 oz) sweetened condensed milk
1 box yellow cake mix (about 15.25 oz)
2 large eggs
1/2 cup butter, melted
1 teaspoon pumpkin pie spice (optional but highly recommended)
1/2 teaspoon salt

How I Make Pumpkin Dump Cake with Sweetened Condensed Milk

I keep this process super simple, and it works every time:

Preheat your oven to 350°F (175°C).
In a large bowl, mix the pumpkin puree, sweetened condensed milk, eggs, pumpkin pie spice, and salt until smooth.
Pour this mixture into a greased 9×13-inch baking dish.
Sprinkle the dry cake mix evenly over the pumpkin mixture. Don’t stir!
Drizzle the melted butter evenly over the top of the cake mix.
Bake for about 50-60 minutes, or until the top is golden brown and a toothpick inserted near the center comes out clean.
Let it cool slightly before serving.

Tips for Pumpkin Dump Cake

A few things I’ve learned after making this recipe multiple times:

Don’t mix the cake mix into the pumpkin mixture; it needs to stay on top to get that signature crust.
Use room temperature eggs for better mixing.
If you want a gooier center, reduce baking time by 5-10 minutes.
Let the cake rest for at least 15 minutes after baking; it sets up nicely and is easier to slice.
Serve with a dollop of whipped cream or a scoop of vanilla ice cream for extra indulgence.

Variations and Substitutions

Feel free to tweak the recipe to suit your taste or pantry supplies. Here are some ideas I’ve tried or heard from fellow bakers:

Swap the canned pumpkin for fresh pumpkin puree if you want a fresher taste.
Use coconut milk condensed milk for a dairy-free twist.
Add chopped pecans or walnuts on top for some crunch.
Mix in a teaspoon of cinnamon or pumpkin pie spice for an extra layer of flavor.
If you’re not a fan of the classic yellow cake mix, try spice cake mix for a warmer, more autumnal vibe.

Mistakes to Avoid

Even simple recipes can trip you up if you’re not careful:

Avoid stirring the cake mix into the pumpkin layer—it ruins the texture.
Don’t skip the butter drizzle; it’s essential for that golden crust.
Make sure your oven temperature is accurate; too hot can burn the top before the inside cooks.
Overbaking dries out the cake, so keep an eye on it after 50 minutes.

Storage

Pumpkin Dump Cake keeps well in the fridge for up to 4 days. Cover it tightly with plastic wrap or store in an airtight container to keep it moist. If you want to reheat a slice, microwave it for about 20 seconds or warm it in a low oven.

You can also freeze leftovers by wrapping individual portions in foil and placing them in a freezer bag. Thaw overnight in the fridge and warm before serving.
