Mix all ingredients into a large bowl. Pour half of the mixture into the bowl of a food processor and process until the chocolate is finely ground. Transfer to an airtight container, then repeat with the remaining mix. Store in the airtight container for up to 3 months.

To make the hot cocoa drink, mix ⅓ cup of the cocoa mix with 1 cup hot milk.
