Preheat oven to 350°F. If you wish to unmold the cakes, grease nine 6-ounce custard cups. Line bottoms of cups with waxed paper. Grease the waxed paper. Dust the inside of the cups with cocoa powder.

In a large bowl beat eggs and sugar with an electric mixer on medium to high speed for 5 to 7 minutes or until thick. Reduce speed to medium; beat in butter and liqueur until blended. (Batter may look curdled, which is okay.) Beat in 6 ounces melted chocolate and vanilla until well combined. Pour 1/2 cup batter into each cup. Bake 20 to 25 minutes, just until set.

Cool cakes on a wire rack 30 minutes.

Meanwhile, for ganache, in a small saucepan bring 1/3 cup whipping cream just to boiling. Remove from heat. Add 3 ounces chopped chocolate (do not stir). Let stand for 5 minutes. Stir until smooth. Cool for 10 minutes.

Serve cakes warm in the custard cups or gently unmold, keeping upright. Top with unsweetened whipped cream, raspberries, and chocolate ganache, if desired.
