Creating the perfect Dark Chocolate Lava Cake is simple if you follow these clear steps:

1. Preheat the Oven: Preheat your oven to 425°F (220°C). Grease four ramekins with butter and dust with cocoa powder.
2. Melt Chocolate and Butter: In a microwave-safe bowl, combine the unsalted butter and dark chocolate. Microwave in 30-second intervals, stirring until smooth and melted.
3. Whisk Eggs: In a separate bowl, whisk together the eggs, egg yolks, and granulated sugar until light and frothy.
4. Combine Mixtures: Gradually fold the melted chocolate mixture into the egg mixture. Stir until well combined.
5. Add Dry Ingredients: Gently fold in the flour and salt until just incorporated. Be careful not to overmix.
6. Add Vanilla: Stir in the vanilla extract for added flavor.
7. Fill Ramekins: Divide the batter evenly among the prepared ramekins, filling each about ¾ full.
8. Bake: Place the ramekins on a baking sheet and bake for 10-12 minutes. The edges should be firm while the center remains soft.
9. Cool: Remove from the oven and let the cakes cool for about 5 minutes.
10. Invert and Serve: Carefully run a knife around the edges and invert each ramekin onto a plate. Serve immediately to enjoy the molten center.
