• Bake the crust for 8-10 minutes, until lightly golden. Remove from oven and let cool slightly.
• While the crust cools, prepare the filling. In a heatproof bowl set over a saucepan of simmering water (double boiler), combine chocolate chips and heavy cream. Stir until the chocolate is completely melted and the mixture is smooth.
