Sunken Raspberry Cakes with Raspberry Sauce

6 ounces bittersweet chocolate, chopped
1/3 cup butter
4 eggs, separated
2/3 cup granulated sugar
2 tablespoons cocoa powder, sifted
Raspberry Sauce (recipe follows)

Preheat oven to 350 degrees F.

Grease eight 6 ounce ramekins; line bottoms with parchment paper. Set ramekins aside.

In large bowl over saucepan of hot (not boiling) water, melt chocolate with butter until smooth; set aside.

In another heatproof bowl over saucepan of gently simmering water, whisk egg yolks with 1/2 cup of the sugar; cook, whisking constantly, until light and thickened, about 8 minutes. Fold one-quarter into chocolate mixture; fold in remaining yolk mixture. Set aside.

In large bowl, beat egg whites until soft peaks form; beat in remaining sugar, 2 tablespoons at a time, until stiff peaks form. Fold cocoa and one-third of the egg whites into chocolate mixture; fold in remaining egg whites. Spoons into prepared ramekins. Bake in centre of oven until puffed and edges are set, about 20 minutes.

Make-ahead: Cover and refrigerate for up to 1 day.
