A rich, layered chocolate cake with a velvety texture and bold flavor. This foolproof recipe combines yolks, meringue, and cocoa for an impressive dessert that’s easy to prepare and perfect for special occasions.
4 large egg whites
3/4 cup white sugar
4 large egg yolks
1/2 cup butter, melted
2 teaspoons vanilla extract
1 teaspoon instant espresso powder (optional)
1/4 teaspoon salt
1/2 cup all-purpose flour
1/3 cup unsweetened cocoa powder (Dutch-process preferred)
2 cups milk, lukewarm
1 tablespoon powdered sugar (optional, for dusting)
Preheat oven to 350°F (175°C). Grease and flour a 9-inch springform or round pan.
In a bowl, whisk egg yolks, sugar (1/2 cup), melted butter, vanilla extract, espresso powder (if using), salt, flour, and cocoa powder until smooth.
Separate egg whites at room temperature. Using clean bowl and whisk, beat remaining sugar (1/4 cup) and egg whites until stiff glossy peaks form.
Gently fold egg whites into yolk mixture in thirds to avoid deflating.
Pour into prepared pan and sprinkle overlapping folds of butter (cut into small pieces) along the top.
Bake for 45-50 minutes until top is firm and center is slightly jiggly. Cool completely, then refrigerate for at least 2 hours.
Dust with powdered sugar before serving.
For optimal texture, use room-temperature egg whites. Leftover Dutch-process cocoa powder is ideal for the darkest flavor. Chill thoroughly for a stable slice.
