Follow these simple steps to make your own Chocolate Lava Cake:

1. Preheat your oven to 425°F (220°C) and grease four ramekins to ensure easy removal of the cakes later on.
2. Melt the butter and chocolate chips together in a microwave-safe bowl. Heat in short intervals, stirring until the mixture is smooth and fully melted.
3. In a separate bowl, whisk the eggs, egg yolks, and sugar until the mixture is fluffy and pale in color. This will help create a light, airy texture in the final product.
4. Gently fold the melted chocolate mixture into the egg mixture, taking care not to deflate the eggs. This step is crucial for maintaining the cake’s delicate structure.
5. Add the flour, vanilla extract, and salt, stirring until just combined. Overmixing can lead to a denser cake, so be cautious.
6. Pour the batter evenly into the prepared ramekins, filling them about three-quarters full to allow room for rising.
7. Bake in the preheated oven for 12-14 minutes. The edges should be firm while the centers remain soft and gooey. Be careful not to overbake, as this will result in a solid cake rather than a lava center.
8. Allow the cakes to cool for 1 minute before carefully inverting them onto plates. Serve immediately for the best molten experience.
