Preheat oven at 500 degrees.

In the top of a double boiler set over simmering water, melt the chocolate and butter. Using a wooden spoon, stir continuously to help the process along.

In a glass bowl, whip the egg yolks, the whole eggs and sugar until tripled in volume. When the chocolate mixture is fully melted, stir it into the egg mixture, while whisking. When all ingredients are well incorporated, whisk in the flour, making sure there are no lumps.

Generously butter six 6-ounce metal molds. Pour batter into molds, up to 1/4-inch from top. Bake in a preheated oven for 5 - 7 minutes maximum. Do not over bake!

Unmold and serve immediately by itself or with your favorite sauce or ice cream.
