Frozen hot chocolate recipe needed
I'm looking for a recipe for frozen hot chocolate and I'd like one that doesn't use a mix, though all of the recipes I've found online do use a mix. I've never had a frozen hot chocolate and don't have any specific end-product in mind other than that I'd like it to be rich rather than watered-down, and I'd love it if most of the preparation could be done ahead of time. I'm making this for a dinner party and am serving it in very small glasses alongside a flambeed dessert (basically mixing up the hot and cold themes for this course by serving a hot dessert over cold ice cream with a cold beverage that is normally hot). Any tried and true recipes would be appreciated!
