FAQs
Can I use pumpkin pie filling instead of puree?
No, it’s too sweet and already spiced—use plain pumpkin puree.
Why stir the cake halfway through?
It helps combine the ingredients and creates a more even, cakey texture.
Is this more like a cake or a cobbler?
The texture is similar to a soft cake or dump cake—moist and spoonable.
Can I double the recipe?
Yes, but you may need a larger slow cooker and increase the cook time slightly.
What if I don’t have a spice cake mix?
Use yellow or white cake mix with added cinnamon, nutmeg, and cloves.
