This sweet crockpot pumpkin spice cake is perfect for those cozy moments when you want a warm, comforting dessert without heating up the kitchen. The blend of pumpkin puree and spice cake mix creates a moist, flavorful treat that's incredibly easy to prepare. It's been a goto in my house during fall get togethers and chilly weekends, especially since it requires minimal handson time.
I made this cake during a busy weekend once and loved how the crockpot did all the work while I handled other things. Now it's my favorite fall dessert to bring to potlucks because everyone asks for the recipe.
Ingredients
- One box of spice cake mix: this gives the base flavor choose a highquality brand for the best spice balance
- Fifteen ounces of pumpkin puree: adds moisture and natural sweetness fresh or canned works but avoid pumpkin pie filling which has added sugar and spices
- Twelve ounces of sweetened condensed milk: brings creamy sweetness and moisture to the cake look for fullfat for richness
Instructions
- Smoothing the Pumpkin Mixture:
- In a medium bowl, combine the pumpkin puree and sweetened condensed milk. Mix thoroughly until smooth and creamy. This mixture forms the rich, moist base for the cake and ensures every bite is luscious.
- Layering the Cake Mix:
- Sprinkle the spice cake mix evenly over the bottom of your crockpot. This even layer is important because it allows the cake to bake uniformly without clumping.
- Adding the Pumpkin Mixture:
- Pour the pumpkin and condensed milk mixture gently over the dry cake mix in the crockpot. Spread it evenly without stirring. Keeping the layers separate initially is key to creating the cake's signature texture.
- Starting the Cook on High:
- Set the crockpot to high and cook for 1 hour. This initial heat activates the baking process and helps set the pumpkin layer.
- Lowering the Heat:
- After the first hour, switch the crockpot to low and cook for 1 more hour. The gentle heat finishes cooking the cake without burning the edges.
- Combining and Final Cooking:
- After two hours of cooking, stir the mixture thoroughly inside the crockpot until well blended. Cover and continue to cook on low for an additional 1 to 2 hours or until the cake sets to your desired consistency. If it still feels too wet, cover and cook in 30 minute increments, checking with a spoon each time.

I adore the warm spices in this cake, especially cinnamon and nutmeg which remind me of my grandmother's kitchen during autumn. It's become a nostalgic treat for our family, sparking memories alongside every serving.
Storage Tips
Store leftovers in an airtight container in the refrigerator for up to five days. To enjoy later, warm slices gently in the microwave or oven to revive that moist texture. If freezing, wrap tightly in plastic and foil then thaw overnight in the fridge.
Ingredient Substitutions
You can swap the spice cake mix for a yellow or butter cake mix with added cinnamon and nutmeg to customize the flavor. Evaporated milk mixed with a tablespoon of sugar or maple syrup can replace sweetened condensed milk in a pinch but expect a slight difference in richness.
Serving Suggestions
Serve warm topped with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of caramel sauce for extra indulgence. Fresh toasted pecans or a sprinkle of powdered sugar add delightful crunch or sweetness.

This sweet crockpot pumpkin spice cake is a cozy, easy dessert that shines in autumn. It's perfect for potlucks and can be made ahead for busy schedules.
