Making Chocolate Lava Cake requires attention to detail, but the process is straightforward. Follow these steps for a perfect result:

1. Preheat the Oven: Set your oven to 425°F (220°C) to ensure it’s hot enough to bake the cakes quickly.
2. Prepare the Ramekins: Grease four 6-ounce ramekins with butter and dust with cocoa powder to prevent sticking.
3. Melt Chocolate and Butter: In a microwave-safe bowl, combine the chocolate and butter. Microwave in 30-second intervals, stirring between each, until smooth.
4. Mix in Sugar: Add the powdered sugar to the melted chocolate and butter, stirring until well combined.
5. Add Eggs and Yolks: Whisk in the eggs and egg yolks until the mixture is smooth and silky.
6. Incorporate Vanilla and Flour: Stir in the vanilla extract and flour, mixing until just combined. Be careful not to overmix.
7. Fill Ramekins: Divide the batter evenly among the prepared ramekins, filling each about two-thirds full.
8. Bake: Place the ramekins on a baking sheet and bake for 12-14 minutes. The edges should be firm, but the center should remain soft.
9. Cool Slightly: Allow the cakes to cool in the ramekins for 1-2 minutes before serving.
10. Serve: Carefully invert each ramekin onto a plate and serve immediately.
