This chocolate cake is extra decadent—and dangerously easy!
Bring saucepan of water to simmer over medium. Place chocolate and butter in medium metal bowl; set over saucepan. Whisk chocolate and butter until melted, about 3 minutes. Off heat, whisk in sugar, then eggs and cocoa powder. Divide among four greased 6-oz. ramekins. Bake at 350° until tops are just set, about 15 minutes. Top with ice cream.
