Notes
Make sure to whisk the milk with cocoa powder to avoid lumps.
Melt the chocolate in a double boiler or MW and keep it ready once the milk is done.
Adjust the sugar as per your taste and preferences. You can add any other sweetener like honey or agave nectar as well.
This milk mixture would be enough for 2 small ice cube trays with 12 holes. If there is some extra milk chocolate mixture left add it in a separate popsicle mold or paper cup.
Make sure to let the ice cubes set properly before taking them out.
You can use the regular ice lolly sticks and cut them in halves. Cocktail sticks can also be used instead.
If planning to use the latter or thinking of making some drinks with these ice cubes, do not add the lolly stick in them. Once they are set remove them from the tray and pop them in the freezer-safe bag. They should stay well for up to a month in the freezer.
