I can't take any credit for this recipe. It is Alton Brown's from the Food Network, but it passed my taste test and I thought I would share (with my own little tweaks, of course). I wanted a good mix to keep on hand at work as an alternate to our company
I cut the recipe in half so that it would fit in a medium size tupperware for work.
1 cup powdered sugar
1/2 cup cocoa (Hershey's Special Dark)
1 1/4 cups powdered milk
1/2 teaspoon salt
1 tiny pinch cayenne pepper
1 pinch cinnamon
Mix everything very well. It can be stored indefinitely in an airtight container. I used 4 heaping spoonfuls for one standard coffee cup. To jazz up a cup of sludge, (oops!) mix in 2 teaspoonfuls and enjoy!
