1. In a microwave-safe container, combine chocolate and 1/3 cup cream. Heat in a microwave oven at 50 percent power, stirring twice, until chocolate is soft, 1 to 1 1/2 minutes total. Remove from oven and stir until sauce is smooth.
2. If sauce is thicker than you like, stir in more cream, a little at a time, to achieve desired consistency. Heat briefly in microwave oven to rewarm.
