CHOCOLATE GANACHE
Place half of the chocolate in a small mixing bowl. In a small saucepan, heat the heavy cream on medium-high heat until it comes to a boil.
Remove the cream from heat and immediately pour over chocolate in the small bowl and stir until chocolate is completely melted. Add the remaining chocolate and stir until chocolate is completely melted. Cool until the ganache is thickened but still thin enough to spread.
Spoon chocolate ganache on top of the cheesecake, spreading to edges. Refrigerate until ganache is set and ready to serve.
