Heat 3 cups of water in a medium-size saucepan over medium-high heat. When the water is steaming, whisk in the cocoa mixture from Step 1. Whisk until smooth and heated through, about 5 minutes. Divide the cocoa between 4 mugs and top each serving with some marshmallows and, if desired, serve with a chocolate spoon (see Chef's Note).
To make a wonderful gift or present for a co-worker, neighbor or teacher, put the cocoa mix from Step 1 into the bottom of a pretty 24-ounce jar. Next, layer the marshmallows on top, close the lid and use colorful ribbon to tie some of the chocolate-covered spoons to the neck of the jar. You can also put the cocoa mix in a Ziploc® Holiday Brand Sliders Storage Bag
and the marshmallows in another and package them together in a cute box, such as a Chinese take-out-style container (you can find these at craft stores). Write the directions for fixing the cocoa on a label or a gift tag and decorate the box with chocolate-covered spoons. The dry cocoa mix will keep for about three weeks.
