This Chocolate Lava Cake or Moelleux au Chocolat is one of the best chocolate desserts, smooth, and delicate with its' crusty top while the inside is still runny, making it simply irresistible.
Butter six ramekins, or aluminum muffins molds and dust with flour.
Melt chocolate and butter over a bain-marie until smooth. Meanwhile beat the eggs with sugar and salt using a whisk or mixer until thick and light yellow. Mix in vanilla extract and flour. Gradually add the melted chocolate and stir well. Pour mixture into the prepared molds.
Preheat oven to 200°C (400°F). Bake for 10 minutes until the edges are firm and the center is still soft. Remove and let cool slightly for few seconds. Run a sharp knife completely around the inside edge of the molds and invert onto plates. Sprinkle powdered sugar on top, and serve immediately.
