Prepare a baking sheet with a silicone mat or parchment paper. Set aside.
Place chocolate in a clear glass bowl so that it's easier to keep an eye on it. Microwave for 30 seconds on high- the chocolate will look shiny. Remove from microwave and stir. Return back to microwave and for 30 seconds. Remove and stir. Continue microwave in 30-second intervals, stirring after each, until totally smooth.
