Melt 6 ounces of semi sweet, bitter sweet chocolate and an entire stick of butter in a microwave at 30 second intervals until it's completely melted.
In a separate bowl, combine two eggs, two egg yolks, 2 ounces of sugar, and a dollop of vanilla extract.
Whisk the egg mixture into the melted chocolate mixture until combined.
Add 2 ounces of all purpose flour to the batter and mix.
Grease each ramekin really well and lightly flour them.
Pour the batter into the prepared ramekins.
Bake at 420 degrees for 12 minutes.
To serve, place a plate over the ramekin, invert it, and tap to release the cake.
