Slow Cooker Pumpkin Dump Cake

Slow Cooker Pumpkin Dump Cake is one of the easiest dump cake recipes there is. You have a pumpkin dump cake that uses a boxed spice cake to help give it that incredible pumpkin spice flavor. 

The name is a little weird, but who cares – it’s cake! I’m a fan of “dump” cakes because of how easy they are to make. It’s usually “dumping” your ingredients and baking. They are messy and delicious! Don’t let the name scare you off. You’ll be missing out if you do!

Slow Cooker Pumpkin Dump Cake

I’ve made dump cake in the oven many times. Last year, I shared this Caramel Apple Dump Cake made with cake mix and pie filling. I wanted to try a dump cake in the slow cooker and see what it would be like.

It was even easier than making one in the oven. You are less risk of burning your dump cake in the slow cooker compared to the oven. Yes, I’ve had a few burnt dump cakes in my past come out of my oven. They literally were dumped in the trash.

    A dump cake was a genius creation! You simply dump ingredients together, and it bakes up into a delicious cake. You will find almost all dump cakes use a boxed cake mix as the base. Then you add in a handful of ingredients to transform the flavor. You get an ultra-moist cake that is loaded with flavor. 

    Bake in the oven or do the slow cooker route as I did with this pumpkin dump cake recipe. 

    Pumpkin Pie Filling or Pumpkin Puree

    You can use either! I could have used pumpkin pie filling in this recipe, but I only had canned pumpkin on hand. For some reason, pumpkin pie filling is really hard to find in stores around here. Figures though, it’s pumpkin season!

    You can easily make your own with a few simple ingredients. Use this homemade pumpkin pie spice, brown sugar and pinch of salt and you are golden.

    This cake is taunting me to dig my fork in.

    How to Serve Pumpkin Dump Cake

    Top with vanilla ice cream or whipped cream. It’s served hot so it will melt quickly. I think that just adds to its charm! Add a dusting of pumpkin pie spice on top of the whipped cream for a fun added look. 

    Variations to the Pumpkin Dump Cake Recipe 

    • Toss in 1/2 cup of walnuts or pecans for a nutty twist. 
    • Use a white or yellow cake mix in replace of spice cake
    • Drizzle caramel over the top before serving for more sweet flavors. 
    • Serve with a butter pecan ice cream instead of vanilla for added rich flavors. 

    How to Make a Slow Cooker Pumpkin Dump Cake 

    The first thing you need to do is spray your slow cooker well with a cooking spray to prevent sticking. Then in a bowl add in your puree, brown sugar, spice and salt. Create an even layer on the bottom of the slow cooker. 

    Now in another bowl do your cake mix and butter and mix till crumbly. Pour over the pumpkin mixture and cook on low for 4 hours. That is all it takes to make this slow cooker pumpkin cake.

    1. Are you literally just mixing the dry cake mix with the butter to make a crumble. Or do you have to prepare the cake mix as it says on the box and add the butter, then pour into the crock pot?
      Thank you.

      1. Yes, just the dry cake mix and the butter together! Don’t follow the box.

      2. How do you cook in the oven?

    2. I made this for the first time today (first time ever making cake in a crockpot) and after cooking for about 7 hours on low and 1 hour on high it’s still very moist bad mushy on the bottom. Almost like it didn’t cook all the way. Also when I mixed the cake and the butter it wasn’t a crumble but more like mushy butter so it didn’t really mix well with the pumpkin on the bottom. Thoughts in what I did wrong?

      1. Hi Kristen! The bottom layer will be softer because it’s the pumpkin pie filling. The top layer should be more cake-like. The butter and the cake mix don’t mixed with the pumpkin at all. Some people also add the cake mix and then add pieces of the butter on top of it. I’m sorry you had issues with it!

      2. Did you use stick butter or spreadable butter? Spreadable has a higher water content. That may have made a mushier mixture.

    3. Hi there. I just cooked this recipe for 4 hours on low and the cake top is still gooey. I’ve put it back in the crockpot pot to cook on high for some time. Will that help?

      1. It might be a little gooey if the pumpkin pie layer seeps into the cake layer. Mine was in the photo too. Cooking it longer should help.

    4. Rinku Vaishnav says:

      Is there a way that I can put chocolate chips in this recipe? If so where should I add them to the pumpkin pie filling or to the cake and butter mix? Also I do make a similar Apple dump cake and I was wondering I cook that on high for 2 hours can I do the same with this?

    5. I haven’t tried it with chocolate chips, but I bet it would be yummy. I would add it to the cake portion of the recipe.

      Cooking on high for 2 hours should work. Just check at the 2 hour mark and see how it looks and if it needs more time.

    6. Arick McCance says:

      I have made Pumpkin Pie Cake for 20 years. This recipe is sketchy at best. Warning: The pumpkin part is Pie -like and the cake part is crumbly. I’ll stick to my recipe includes sweetened condensed milk and three eggs in the pie part.
      Good luck to all
