FAQs
What is a dump cake?
A dump cake is a simple dessert where all ingredients are “dumped” together and baked without complex mixing or layering. Traditional dump cakes often combine cake mix, fruit, and butter; this version uses pudding and milk to achieve a moist, fudgy texture.
Can I use a different flavour of cake mix?
Yes, you can experiment with other cake mix flavors, but chocolate pairs best with the peanut butter cups to create a rich, balanced dessert.
