- Prepare cheesecake filling: Melt semi-sweet chocolate with heavy cream and vanilla extract until smooth; set aside.
- Beat cream cheese and sugar until smooth. Add flour, sour cream, vanilla extract, and eggs; mix well.
- Fold in the melted chocolate mixture until combined.
- Pour cheesecake filling over cooled cake layer and bake for 40-45 minutes or until center is almost set. Cool completely.

Notes
For best results, ensure all dairy ingredients are at room temperature before mixing. Allow the cheesecake to chill thoroughly to set layers properly. The pastry cream adds a classic Boston Cream Pie flavor and texture contrast.
