Warm Chocolate Pudding Cakes with Caramel Sauce

Preheat oven to 350 degrees. Butter four 6-ounce ramekins, then coat lightly with sugar, tapping out excess. In a microwave-safe bowl, combine butter and chocolate. Microwave until melted, about 1 minute; stir until smooth. (Or melt mixture in a heatproof bowl set over, not in, a pan of simmering water.)

In a large bowl, whisk together sugar, eggs, yolks, flour, and salt; add chocolate mixture and whisk to combine. Fill each ramekin three-quarters full with batter; place on a rimmed baking sheet and refrigerate 15 minutes.

Bake until center of a cake is soft but not wet when pressed, 27 to 30 minutes. Let cool 5 minutes. Serve cakes warm, topped with caramel and whipped cream.
