To make the filling: Heat the heavy cream in a pot over medium-low flame, until it simmers slightly around the edges.
Remove from the heat; add the chocolate chips and stir until melted and smoothed out.
Beat the eggs in a small bowl until blended and add them to the chocolate mixture, stir until completely blended.
Pour the filling into the tart shell and bake at 375 degrees for 30 minutes until the filling is set and the surface is glossy.
If you see any bubbles or cracks forming on the surface, take the tart out right away - that means it is beginning to become over baked. Cool before cutting.
Garnish with fruit and chopped pecans. A dusting of powder sugar on half of the tart would also be nice here.
Notes
While baking, the filling for the chocolate tart will puff up a bit. Once the tart has been removed from the oven and is cooling, the tart will flatten back out.
