This keto pumpkin dump cake has unbeatable flavor with layers of pumpkin pie, spongy yellow cake and a pecan streusel topping. Not only is it a crowd favorite, but it uses a box keto cake and all of the ingredients are dumped into the baking dish for an easy keto dessert.

For a quick keto holiday dessert that doesn’t require a lot of fuss, this keto pumpkin dump cake is your solution. It combines flavors of pumpkin pie with a keto cake in the middle and a crunchy pecan streusel topping. And separates them into 3 layers as the cake bakes!!!

Dump Cakes are a delicious twist on a traditional cake where you don’t have to bring out a bunch of bowls or utensils to make your cake. Everything is basically made in one bowl (although I do recommend making the pumpkin components in a separate bowl so that we can easily mix them without messing up the parchment lining.)

Using a few ingredients for a pumpkin pie base layer, like eggs, pumpkin puree, cream and sweetener, it is poured into a square baking dish then keto cake mix is dusted on top of the pumpkin along with melted butter and pecans.

Once baked, the cake mix bakes into the pumpkin layer to form a light, spongy gluten free cake on top with a pumpkin custard layer on the bottom.

Top with whipped cream or sugar free ice cream!

    What is a dump cake?

    Dump cakes are similar to cobblers in that they start with a layer of fruit filling that is dump in a baking dish. In this case, our fruit is pumpkin.

    Cake mix is sprinkled on top of the fruit and does not need to be mixed into the fruit. The dry cake mix stays on top to help form a crumble streusel like topping.

    Keto cake mix

    The keto cake mix used in this pumpkin dump cake recipe was a yellow cake mix by King Arthur Baking Company. This cake mix is gluten free, sugar free and there are only 2 grams of net carbs per serving. 

    As the keto dump cake baked, the moisture from the pumpkin filling and the butter help to create a spongy, moist cake layer.

    There are other keto cake mixes on the market; however, I have not tested them in this recipe.

    Storage information

    This pumpkin dump cake recipe is delicious served warm especially if topped with whipped cream or vanilla ice cream.

    To store the keto dump cake, cover and store in the refrigerator for up to 4-5 days. I don’t recommend freezing this cake as the cake layer may not keep it’s texture.

    Keto Pumpkin Dump Cake: FAQS

    Why is it called a dump cake?

    All of the ingredients for a dump cake are "dumped" into the baking dish or cake pan without mixing the cake mix into the ingredients.

    Can I use all heavy cream?

    Yes, you can use all heavy cream in this recipe; however, I wouldn't recommend all nut milk. If you do need a dairy free option, use all coconut cream instead of heavy cream.

    Can any cake mix be used in this recipe?

    I sure any keto cake mix can be used in this recipe; however, I haven't tried them all. This recipe has only been tested using the King Arthur Keto Cake Mix.

      1. I used King Arthur Baking Sugar Alternative. You can use any as long as it measures cup for cup with regular sugar.

    1. Loved how easy this was to make and how delicious it came out. Even my husband, who does not like artificial sweetener ate this cake. I used Swerve Granular as the sweetener. Delicious!

    2. Very good recipe! I couldn’t find the King Arthur Keto cake mix so I used Pillsbury Keto cake mix, worked just fine. I used allulose as my sugar substitute. When I make it again, I won’t use an 8 x 8 square pan as it was to thick for my liking and when cut into 9 pieces, it’s too rich. This is a definite make again recipe, glad I tried it. Thanks for sharing!
