Chocolate Decadence (Flourless Fallen Soufflé Cake)
A flourless chocolate cake built on whipped eggs and bittersweet chocolate that rises in the oven and settles as it cools. Light, structured, and intentionally soft in the center, this is a fallen soufflé-style cake with deep chocolate flavor and a clean finish.
Equipment
- Heatproof mixing bowl
- Saucepan (double boiler setup)
- Stand mixer or hand mixer
- Rubber spatula
- 9-inch springform pan (preferred for height)
- Parchment paper
Ingredients
- 10 ounces bittersweet chocolate 65–70%, chopped
- 10 tablespoons unsalted high-fat butter
- ¾ cup granulated sugar
- 12 large eggs separated
- 1 teaspoon vanilla extract
- ½ teaspoon kosher salt
- Cocoa powder for finishing
Instructions
- Preheat oven to 325°F.
- Line a 9-inch springform pan with parchment and lightly butter.
In a heatproof bowl over gently simmering water, melt:
- 10 oz bittersweet chocolate
- 10 tablespoon butter
- Stir until smooth. Remove from heat and cool slightly.
In a bowl, whisk together:
- 12 egg yolks
- ¾ cup sugar
- 1 teaspoon vanilla
- ½ teaspoon kosher salt
Whisk until slightly thickened and smooth.
- Slowly incorporate the warm chocolate mixture into the yolk mixture, stirring gently until fully combined.
In a stand mixer, whip 12 egg whites to soft-medium peaks.
- Not stiff—structure comes from controlled air, not rigidity.
Fold the whipped egg whites into the chocolate mixture in 3 additions, using a spatula.
- Fold gently. Maintain as much air as possible without leaving streaks.
- Pour batter into prepared pan and smooth lightly.
Bake for 35–40 minutes, until:
- edges are set
- center is puffed but still soft
- Remove from oven and cool completely in the pan.
- The cake will rise significantly and collapse as it cools.
- This is intentional and defines the final texture.
Notes
Notes
Use high-quality 65–70% chocolate (bar form) for proper structure and flavor.
Avoid chocolate chips—they interfere with melting and texture.
Use unsalted high-fat butter for better emulsification and a smoother finish.
Egg whites should be soft-medium peaks, not stiff—overwhipped whites create a dry collapse.
The cake is not meant to fully set in the center—it should remain soft and tender.
