Hot cocoa in a jar is the rare homemade gift that everyone is genuinely happy to receive, when the mix is good and the size fits the relationship. A quart jar for a coworker is odd; a tiny jar for your best friend feels thin. Here is one tested mix recipe and the gift ladder built on top of it: three sizes, three price points, three kinds of people on your list, all from one afternoon of layering.
Short answer: Layer cocoa powder, sugar, powdered milk, mini chocolate chips, and mini marshmallows in an airtight jar, 2 parts cocoa, 2 parts sugar, 1 part powdered milk, and gift it with instructions: 3 heaping tablespoons per cup of hot milk. Single-serve jars suit teachers and neighbors, a quart jar with a mug suits friends, and a full cocoa kit basket suits close family.
