Like fudge on a stick. Swirl these blocks into a mug of hot milk and enjoy luscious hot chocolate, or nibble the chocolate blocks directly from the stick. These cocoa blocks are fantastic for kids and adults alike! They taste amazing and are fun to swirl in your hot beverage-- coffee or hot milk.Think of these confections as you would ganache. They will keep at room temperature 3-4 days, in the fridge about 10 days, in the freezer up to 30 days. Prep time does not include the overnight set-up time.
