What Kind of Cake Mix Should I Use?
I used a chocolate fudge cake mix for this recipe.
The important thing to remember is that you are using the dry cake mix as an ingredient in the recipe—you do not prepare the cake mix according to the directions on the box.
You’re not adding the eggs, oil or water listed on the cake mix box.
Instead, the milk and pudding mixture provides the moisture needed for this recipe.

Can I Make Hot Chocolate Dump Cake Ahead?
Yes.
The cake can be baked ahead of time and stored until you’re ready to serve it.
For the best presentation, I recommend waiting to add the final hot cocoa dusting and optional toppings until just before serving.
That way the top looks fresh and pretty.

Yes!
If you want that cozy hot-chocolate experience, serve a portion slightly warm with whipped cream or a scoop of vanilla ice cream.
The warm chocolate cake and soft marshmallows are especially delicious together.
What to Serve With Hot Chocolate Dump Cake

A scoop of vanilla ice cream melting over warm chocolate cake is especially good.
