Preparation
1.
In the top of a double boiler set over simmering water, heat the butter
and chocolate together until the chocolate is almost completely melted.
While that’s heating beat together the eggs, yolks and sugar with a
whisk or electric beater until light and thick.
2.
Beat together the melted chocolate and butter; it should be quite warm.
Pour in the egg mixture, and then quickly beat in the flour, just until
combined.
3.
Butter and lightly flour four 4-ounce custard cups, molds or ramekins. Tap
out the excess flour, then butter and flour again.
Divide the batter among the molds.
(At this point you can refrigerate the desserts, for up to several
hours until you are ready to eat dinner. It is then best to bring them
back to room temperature before baking.)
4.
Preheat the oven to 450 F. Bake the molds on a tray for about 10 minutes;
the centers should still be quite soft, but the sides will be set. If you
forgot to take them out of the refrigerator, it will take about 4 more
minutes of baking.
5.
Invert each mold on to a plate and let it sit for 10 seconds. Unmold by
lifting one corner of the mold; the cake will fall onto the plate. If not
run a knife around edge to loosen. Serve
immediately. Some serve with vanilla ice cream or mint fudge sauce
or both. But I think the cake stands on its own.
