When ready to make, you will also need 1 cup of milk per person you are planning to serve.
In a large bowl or sealable jar whisk together confectioner’s sugar, cocoa powder and salt. Portion into smaller jars or keep in a well-sealed container at room temperature.
When ready to use scoop 2 rounded tablespoons into a mug with ½ oz semi-sweet chocolate, add milk, and microwave.
