4. Bake until just set, 8-10 minutes. Remove from oven; cool.

For chocolate filling:
1. In a small, heavy saucepan, melt butter, chocolate pieces and chocolate chips over low heat, stirring frequently. Let cool.
2. In a bowl, combine eggs, sugar, flour and vanilla. Stir in cooled chocolate mixture.
