6 ½ (1 oz) squares semisweet chocolate, finely chopped ½ cup butter, cut into 8 pieces 3 eggs, room temperature ⅓ cup white sugar 2 Tbs all-purpose flour 4 tsp unsweetened cocoa powder 1 pinch salt
Directions
Preheat the oven to 400 degrees. Grease and flour four 6-ounce ramekins.
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.
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.
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.
