01 - Preheat oven to 425°F. Generously butter four 6 oz ramekins and dust with cocoa powder, tapping out excess.
02 - Set heatproof bowl over pot of simmering water. Add chopped chocolate and butter, stir until completely smooth and melted. Remove from heat to cool slightly.
03 - In separate bowl, whisk granulated sugar, whole eggs, and egg yolks until mixture thickens and becomes pale in color.
04 - Pour warm chocolate mixture into egg mixture, stirring constantly. Add vanilla extract and salt, mixing well.
05 - Sift flour over batter and fold gently until just incorporated. Be careful not to overmix.
06 - Divide batter evenly among prepared ramekins. Place on baking sheet for easy handling.
07 - Bake 11-12 minutes until edges are firm but center remains soft and jiggly. Avoid overbaking for molten texture.
08 - While cakes bake, combine raspberries, sugar, lemon juice, and water in saucepan over medium heat. Cook 5 minutes, stirring until berries break down completely.
09 - Press mixture through fine mesh sieve into bowl, removing seeds. Allow to cool while cakes finish baking.
10 - Let cakes rest 1 minute. Run knife around edges, invert onto serving plates. Dust with powdered sugar, drizzle with coulis, and garnish with fresh berries and mint. Serve immediately.
