Instructions

1. 1
   Preheat the oven to 400 degrees F (200 degrees C). Grease and flour four 6-ounce ramekins.
2. 2
   Place chocolate and butter in the top of a double boiler over simmering water. Stir frequently, scraping down the sides with a rubber spatula to avoid scorching, until chocolate is melted, about 5 minutes.
3. 3
   Combine eggs and sugar in a large bowl; beat with an electric mixer until pale and thick, about 5 minutes. Mix in melted chocolate, flour, cocoa powder, and a pinch of salt until combined. Pour batter into the prepared ramekins and place on a baking tray.
4. 4
   Bake in the preheated oven until the sides are set but the middle is still jiggly, 10 to 13 minutes. Let cool for 5 minutes before serving.
