In a very large container mix all ingredients until well blended. Then put into a food processor and process for 3 minutes. Do not put all of it in the processor at once. About 2 cups at a time.
To serve, combine 1/4 cup mix with a cup or 6 ounces of hot water. May also use miniature marshmallows or chocolate curls to garnish. Store mix in an airtight container. Will keep for a long time unless you drink it all up.
