This may be the easiest hot cocoa mix ever! Really!
It has only three ingredients. Powdered milk, sugar, and cocoa. Simpy mix in a large bowl, 2 1/2 - 3 cups of powdered milk, 2 cups granulated sugar, and 1 cup plus one tablespoon of baking cocoa. Mix them together in the bowl, and you can be finished there, or in batches that will fit in your food processor, just pulse for a few seconds, and you'll have a super fine powder that will mix very nicely. Just add hot water or milk to about 3-4 heaping teaspoons, and you're good to go! I use about half milk/half water, but you can use any mix or just one or the other to fit your taste.
Now pack it into a jar to give as a nice and thoughtful gift to a cocoa lover in your life, or for yourself, add a label with mixing instructions and you're done! Easy! It took literally about 5 minutes to make one batch of cocoa. I made three batches in just a few more minutes, and it stores for a long time! Just like the label says....Enjoy! :)
