Place the 1/4 cup of chocolate chips in a microwave-safe bowl. Microwave in 20-30 second intervals, stirring between each, until the chocolate is smooth and fully melted. Alternatively, use a double boiler to melt the chocolate. Typically, you would add coconut oil to the chocolate. But you want this chocolate to be as thick as possible so it will hold the bat together, so I've omitted the coconut oil.
