Make sure that you make your very own Homemade Pumpkin Pie Spice for this recipe! Or maybe learn a Traditional Pumpkin Pie Recipe instead, with some whipped cream or Pumpkin Spice Frozen Whipped Cream Toppers to top if off.

Karlynn’s Recipe Notes
- Skill Level: This recipe is easy, as most dump cake recipes are.
- Total Time: This cake will take you approximately 75 minutes from start to finish.
- Variations: This cake would be even more delicious with the addition of some Whipped Cream Cheese. Perhaps even a drizzle of Caramel Syrup or Easy Salted Caramel Sauce and a sprinkling of chopped nuts. Why not try mixing some raisins into the cake batter?
- Tools Needed: The joy of a dump cake is that you can make it with so few tools. You’ll need a large bowl, a spoon or hand mixer, and a 9×13 cake pan. If you like to use cooking spray for greasing your pans, keep some handy.

What You’ll Need For Ingredients
Spice Cake: Don’t use a plain vanilla or white cake for this recipe. You’ll absolutely want the flavours and texture of a spice cake, whether you use a mix from the store or make your own cake from scratch.
Pumpkin Puree: This will add moisture and richness to the cake, but did you know that pumpkin is also incredibly nutrient-dense? It’s packed full of vitamins and fiber. If you are using homemade pumpkin puree, you will likely need to strain it in a sieve or cheesecloth to remove excess moisture.
Pecans: Chopped pecans in your cake batter will add flavour and crunch, while the ones on the top of the cake will make a crispy layer. You can use walnuts in place of pecans, but the the texture and taste will be slightly different.

How To Make Pumpkin Dump Cake
This is a brief overview of the recipe. The full list of ingredients and step-by-step instructions are in the recipe card below.






- Preheat oven to 350°F and grease a 9×13 baking dish.
- In a large bowl, mix the cake mix, pumpkin, evaporated milk, pumpkin pie spice, cinnamon, sugars, and eggs. Pour into prepared cake pan.
- Sprinkle evenly with pecans and cut cold butter into thin slices. Place butter slices on top of the cake, spacing them evenly.
- Bake for 1 hour. Serve warm or cold with some whipped cream.

Storage Instructions
Fridge: This cake doesn’t need to be refrigerated, but if you’d like it chilled just put it in a covered container in the fridge for 3-4 days.
Freezer: Once the cake is cooled, you can freeze it either as a whole or in individual slices, in a sealed container for several months. Just take out a piece and let it defrost on the counter, or microwave it for a minute, and you’ll have a tasty snack.

DONNA says
I had been looking for a pumpkin recipe with nuts and pumpkin, but without a heavy crust. This was it. And it was ABSOLUTELY DELICIOUS!!! Everyone at the Thanksgiving table loved this — they say it tastes exactly like Autumn. I made it last year and will make it again this year. It is now one of my “GO TO” recipes for Thanksgiving. THANK YOU!!!
Sue says
Am I missing the cake mix?
Janet says
This was very good, followed recipe exactly. The only thing I would do when making this again would be to put the pumpkin purée on paper towels to take out some of the liquid. The filling I thought was a little too thin, would have much preferred it to be firmer.
Karlynn, thanks for sharing.

Are you sure about the 5241 calories.
At that amount no one would want to make this.
Terry says
The 5241 calories are for the entire recipe (12 servings), not per serving. It’s quite confusing that she didn’t do the conversion.
It works out to 436.75 kcal/serving – still pretty hefty – but I don’t think most people would be eating it every day.
The 1c chopped pecans are 700+ kcal alone, never mind the 1c sugars & 3/4c butter!

The calculator is only as good as the third party that does it, it can be out of my hands which is why I warn people not to depend on it!

If I want to eliminate all nuts what could I use for the crunch effect?
Terry says
Everything ok with your website? I posted my comment less than 5 minutes ago & it says 6 HOURS ago. Hmm…
Terry says
Hi Karlyn! I just want to confirm that this recipe requires 1-29oz can pumpkin PUREE.
I, too, am from the Canadian prairies, and I’ve never seen pumpkin puree in 29 0z cans, in my regular stores, I.e. Walmart, Superstore, Safeway, Co-op. Pumpkin PIE FILLING comes in cans that size, but…
Thanks, from Alberta!
Karlynn Johnston says
The 796 ml pumpkin by ED Smith brand is what you use for Canada, then 29 ounce Libby etc in the States!
