Prepare Your Equipment

• Preheat your oven to 425°F (220°C).
• Grease four ramekins with butter and lightly dust with flour. Set them aside.

2. Melt the Chocolate and Butter

• Combine the semi-sweet chocolate and butter in a microwave-safe bowl.
• Heat in 20-second intervals, stirring after each, until fully melted and smooth.

3. Mix the Eggs and Sugar

• In a separate bowl, whisk the eggs, egg yolks, and sugar until pale and slightly frothy.
• Add the vanilla extract and stir to combine.

4. Combine Ingredients

• Gradually fold the melted chocolate mixture into the egg mixture.
• Sift in the flour, add a pinch of salt, and gently stir until just combined.

5. Fill the Ramekins

• Divide the batter evenly among the prepared ramekins, filling each about three-quarters full.

6. Bake to Perfection

• Place the ramekins on a baking sheet and bake for 12-14 minutes. The edges should be set, but the center should remain soft.

7. Serve and Enjoy

• Let the cakes cool for 1 minute, then carefully invert them onto plates.
• Serve immediately with a dusting of powdered sugar, a scoop of vanilla ice cream, or fresh berries for garnish.
