It's a perfect idea for a big group and a lot of fun to see what add-ins everyone enjoys. We had the aforementioned Bailey's and Peppermint Schnapps, chocolate-dipped marshmallows, candy canes, caramel bits, mini chocolate chips, and chocolate hazelnut Pirouettes.
Here's the most exciting thing... you don't need to wait until Christmas to enjoy it. Hot Chocolate is great in February, too!
Hot Chocolate Bar
4 1/2 cups whole milk
1/4 cup unsweetened cocoa
1/4 cup sugar
In a medium saucepan, heat 4 cups of the milk over low heat, being very careful not to let the milk boil. In a small bowl, mix together the cocoa, sugar, and the remaining 1/2 cup milk. Add the cocoa mixture to the warm milk and continue to warm the cocoa until hot.
Pour into 4 mugs and garnish.
I tripled the recipe and it made enough for thirteen of us. It's pretty rich, so you probably don't need more than a cup - especially depending on your add-ins - but hey, I don't judge. Drink away.
I made this a day ahead and kept it in the refrigerator until we were ready to enjoy it. It heated up on the stove pretty quickly - in maybe 20 minutes or so - over medium heat. Again, be careful not to let the milk boil. Trust me, no amount of Bailey's can help burnt milk.
