Melt the chocolate and the coconut oil together using your preferred method (
such as a double boiler) and pour it into a bowl. Carefully dip the rounded top of the donut holes into the chocolate, allowing any excess to drip off into the bowl. Insert the pretzel stick into the top of the donut hole. Transfer back to the plate and repeat for all donut holes. Place in the fridge for 10 minutes or until the chocolate hardens.
