Hot Cocoa Mix

3 cups nonfat dry milk
2 cups confectioner's sugar
1 ½ cups Dutch-processed cocoa powder
1 ½ cups white chocolate chips
1/4 tsp. salt

Combine ingredients in large bowl. Working in two batches, pulse ingredients in food processor until chocolate is finely ground. To make hot cocoa, stir 1/3 cup mix into 1 cup hot milk. Top with whipped cream or mini marshmallows. Mix can be stored in an airtight container for three months. The white chocolate chips give it a creamy texture, and accentuate the chocolate flavor.
