Here is the recipe I used this time:
2 cups powdered sugar
1 cup cocoa powder (dutch-processed if available)
2 1/2 cups powdered non-fat milk
1 teaspoon salt
2 teaspoons cornstarch
Mix all together and prepare to enjoy. I use 3 heaping tablespoons into a mug of hot water. Mix well. YUM!!
This will make 2 1/2 cups of mix. This will fill up a quart jar and you will have a little bit left over. Next time I do this, I am going to put it into smaller bags and then seal with my vacuum sealer. This way it will be safer for our backpacking trips ... don't have to worry about broken glass jars.
