Nana's Spanish Style Hot Chocolate (Hot Chocolate Pudding)

whole milk

sugar (I prefer raw sugar for the caramel-like flavor it imparts here., or more, depending on sweet you like it)

good quality Dutch process cocoa powder

arrowroot powder or cornstarch (use less for a more drinkable product and more for a thick, pudding-like finish.)

Optional (for garnish:)

Whipped Cream

Shaved Chocolate

Cinnamon Sugar

Graham Crackers or Pretzels for dipping
