Here are some great ideas and photos. I'll probably choose a little from each to make my hot chocolate bar. (I'm sure there are more sweet ideas on Pinterest.)
Real mom didn't have a picture of the actual bar but she has LOTS of good ideas for mix-ins and flavored cocoas!
Hostess with the Mostess even has some really fun printables for the hot chocolate bar. Wouldn't this be fun for New Year's Eve!
I also plan to put out some Peppermint Schnapps and Kahlua for the adults to add. I'm thinking this just might be more popular than the wine!!
