Flourless Chocolate Cake

Melted bittersweet chocolate and butter beaten with eggs into a batter that bakes into something between a cake and a truffle. It sinks slightly as it cools, which is expected.

Ingredients

Method

  1. Heat the oven to 375 degrees F (190 degrees C), butter an 8-inch (20 cm) springform pan, and line the bottom with a parchment round.
  2. Melt the bittersweet chocolate with the unsalted butter in a bowl set over barely simmering water, stirring until smooth, then take it off the heat and let it cool for 5 minutes.
  3. Beat the eggs with the white sugar, instant espresso powder, vanilla extract, and salt on high until the mixture is pale, thick, and falls in a ribbon that sits on the surface, about 4 minutes.
  4. Fold a third of the egg mixture into the warm chocolate to loosen it, then fold in the rest along with the unsweetened cocoa powder, stopping as soon as no streaks remain.
  5. Pour into the pan and bake until the edges are set, the center is puffed and just barely firm, and a pick comes out with thick moist crumbs, 25 to 30 minutes.
  6. Cool completely in the pan on a rack, about 2 hours, then release the ring and dust the top with cocoa powder.

Notes

  • Overbaking turns it dry and crumbly; the center should look slightly underdone when it comes out.
