I make my own instant hot chocolate mix. This way you know what is in it, and it is also easy to take along since it is instant. I got the recipe off a bag of instant nonfat dry milk and tweaked it a tad bit for my sugar free life style.
Hot Chocolate Mix
2 cups instant nonfat dry milk
1/2 cup unsweetened cocoa
1 cup Splenda
1/4 tsp. salt
1 vanilla bean
Place all ingredients in a blender or food processor and blend until you have a fine powder. Store in an airtight container. To make, mix 3T.(or to taste) of dry mix with 1 cup of boiling water.
Makes approximately 14 cups.
I also like to kick it up a bit and add 1/2 tsp. cinnamon and an 1/8 tsp. of chili powder(don't knock it
until you try it, trust me)
Enjoy.
