If desired, melt the white chocolate in a heat proof bowl in the microwave in 20 second intervals until completely melted. Stir in the coconut (or vegetable/canola oil) until combined. Transfer the melted white chocolate to a cup wide enough to fit a popsicle. Quickly dip as much of the popsicle as you desire into the white chocolate and shake off any excess. If desired, quickly roll the popsicle in graham cracker crumbs or sprinkle onto the white chocolate, pressing slightly to adhere.
