Im looking for an easy plain chocolate fudge recipe. I need one that uses chocolate chips instead of cocoa. Thank you

I was looking through a recipe book and found a recipe for chocolate-coated Nut Goodies. In the recipe, it said to melt 1 block of wax and chocolate chips together. I’ve never heard of such a thing. The recipe book isn’t a real published book, it’s a collection that was made by my kindergarten class over 20 years ago. Is this a mistake or is there really some kind of wax that’s used in candy-making?

Growing up, we used to make an awesome fudge.
I know for a fact it had 3 bags of chocolate chips, 1 pint marshmallow creme, and 1 stick of butter.
I know it also had evaporate milk and sugar, but I don’t remember how much of those two ingredients.
Does anyone have this recipe?
