Alton Brown Hot Cocoa Mix (Can Be Dairy-Free)

The original recipe can be found at http://www.foodnetwork.com/recipes/alton-brown/hot-cocoa-recipe.html, I'm posting here for my convenience. For dairy-free hot cocoa, omit powdered milk from the mix; warm your choice of dairy-alternative and gradually add to cocoa mix in mug. (I prefer 3T mix to approx 6oz unsweetened coconut milk, personally).

• Ready In: 8 mins
• Serves: 6-8

Ingredients

• 2  cups powdered sugar
• 1  cup cocoa powder (dutched, preferably)
• 2 1⁄2 cups powdered milk (omit for dairy-free mix)
• 1  teaspoon salt
• 2  teaspoons cornstarch
• 1  pinch cayenne (to taste, can omit)

Directions

1. Combine all ingredients in a mixing bowl and incorporate evenly. Seal in airtight container till ready to use.
2. Warm water or dairy-alternative.
3. Alton's directions at the above-mentioned web address state to fill mug half-full with mix and add liquid. I can't do dairy so my experience is without the bulk of the pwd milk. I put 3 T in my mug, add a little of my warmed coconut milk and mix well. Add a bit more coconut milk, mix, and continue until filled and thoroughly incorporated.
4. (Somebody else has posted his homemade marshmallows on food.com if you're so inclined. I haven't tried them yet.).
