To Make Hot Chocolate
Heat a 1 cup to 1 1/2 cups of milk in the microwave.
Stir in 1 tablespoon of hot cocoa mix.
Add in 1/4 teaspoon of vanilla, if desired.
Enjoy!
Notes
If you don't have powdered milk on hand you can leave it out of the mix. But I think it does make the mix more creamy. For the dairy free option, I use Better Than Milk Powder Milk Alternative or Vance's DariFree for the powdered milk.
