Decadent chocolate lava cake with a molten, gooey center is a showstopping family restaurant-style dessert. This rich, dramatic treat delivers the ultimate chocolate experience in every bite.
Preheat the oven to 425°F (220°C) and generously butter four 6-ounce ramekins. Dust the inside with flour, tapping out any excess.
In a microwave-safe bowl, combine semisweet chocolate and unsalted butter. Microwave in 30-second bursts, stirring, until smooth and fully melted. Let cool for 5 minutes.
In a mixing bowl, whisk together the eggs, egg yolks, and powdered sugar until pale and slightly thickened. Stir in the vanilla extract and salt.
Fold the cooled chocolate mixture into the egg mixture, combining thoroughly. Sift in the flour and gently mix until no streaks remain, being careful not to overmix.
Divide the batter evenly among the prepared ramekins. Place on a baking sheet and bake for 11–13 minutes, watching for the edges to be set while the centers remain soft.
Remove from the oven and let rest 1 minute. Run a thin knife around the edges; invert each ramekin onto a plate. Serve immediately to enjoy the molten center.
