1/3 c. instant coffee granules
1/2 c. boiling water
1 can (14 oz.) sweetened condensed milk
2 c. cold water
1 qt. cold low-fat chocolate milk

Place coffee granules in medium bowl. Add boiling water and whisk together. Whisk in sweetened condensed milk and cold water until completely blended. Pour coffee mixture into 2 quart pitcher. Add chocolate milk; stir to mix. Chill at least 1 hour before serving.

This is also good warmed in the microwave for a cold-weather treat.
