Chocolate Cloud Cake

A rich, flourless chocolate cake that is light and airy, made by folding whipped egg whites into a dense chocolate batter, resulting in a mousse-like texture.

Ingredients

Scale
  • 8 ounces (225 g) high quality semi-sweet or bittersweet chocolate, chopped
  • 1/2 cup (113 g) unsalted butter, room temperature
  • 6 large eggs, separated (4 egg whites, 2 whole eggs or 5 eggs separated)
  • 1 cup (200 g) granulated sugar
  • 1 teaspoon vanilla extract
  • 1 tablespoon instant coffee or espresso powder (optional)
  • 1/2 teaspoon cream of tartar

Instructions

  1. Preheat oven to 350°F (175°C). Line the bottom of an 8" or 9" springform pan with parchment paper.
  2. Melt the chopped chocolate and butter together in a double boiler or microwave until smooth. Set aside to cool slightly.
  3. In a large bowl, whisk the egg yolks (or 2 whole eggs plus 4 yolks) with half of the sugar until smooth. Stir in vanilla extract and the melted chocolate mixture.
  4. In the bowl of a stand mixer, add the egg whites and cream of tartar. Beat on medium speed until soft peaks form.
  5. Gradually add the remaining sugar to the egg whites and beat on high until stiff but glossy peaks form.
  6. Fold about one-third of the whipped egg whites into the chocolate mixture to lighten it. Then gently fold in the remaining egg whites carefully to keep the batter airy and mousse-like.
  7. Pour the batter into the prepared pan and smooth the top with a spatula.
  8. Bake for about 25-30 minutes, or until the cake is set and a toothpick inserted in the center comes out with moist crumbs.
  9. Remove from oven and cool in the pan. Optionally, top with whipped cream and dust with cocoa powder before serving.

Notes

1. Be careful not to overmix when folding egg whites to keep the cake light and airy.
2. Using high quality chocolate improves the depth of flavor.
3. For extra flavor, espresso powder or instant coffee can be added to intensify the chocolate taste.
