Flourless Chocolate Cake
A rich, decadent single-layer cake made entirely without flour—just chocolate, eggs, butter, and a touch of sugar. Dense and fudgy on the inside with a subtle crackle on top.

Ingredients
- 6 ounces dark chocolate (60% cacao or higher)
- 6 tablespoons butter, unsalted
- 4 whole eggs, large
- ½ cup sugar, granulated
- ¼ teaspoon salt
- 1 teaspoon vanilla extract
- 1 tablespoon cocoa powder, unsweetened (for dusting)
Instructions
- 1
Set the oven to 350°F and wait until the indicator light or beep tells you it has finished heating, about 10 minutes.
- 2
Line the bottom of a 9-inch round cake pan with parchment paper, then lightly brush the sides with butter so the cake doesn't stick.
- 3
Chop the dark chocolate into small pieces about the size of a pea—breaking it into rough shards is fast enough; you don't need perfect uniformity.
- 4
Place the chopped chocolate and 6 tablespoons of butter into a heatproof bowl and set it directly over a pot of simmering water (the water should not touch the bottom of the bowl).
- 5
Stir the chocolate and butter together over the simmering water until melted and smooth, about 2 minutes, then remove from heat and let cool for 2 minutes.
- 6
Separate the eggs: crack each egg over a bowl, gently transfer the yolk back and forth between the two shell halves to let the white fall into the bowl, then place the yolk in a separate bowl; repeat for all 4 eggs.
- 7
Pour the melted chocolate into the bowl with the egg yolks, add 1 teaspoon vanilla extract and 0.25 teaspoon salt, then stir until fully combined and no streaks of chocolate remain.
- 8
Using an electric mixer or whisk, beat the egg whites on high speed until stiff peaks form—when you lift the beaters, the whites should stand straight up like a mountain, about 3 minutes.
- 9
In another bowl, whisk together the 0.5 cup sugar with the egg yolks and chocolate mixture until the mixture is smooth.
- 10
Pour the chocolate mixture into the bowl with the beaten egg whites, then use a rubber spatula to lift the chocolate from the bottom up and over the whites; rotate the bowl a quarter turn and repeat until no white streaks remain, about 15 folds.
- 11
Pour the batter into the prepared pan, smoothing the surface with a spatula so it is level, then set it carefully in the oven on the middle rack.
- 12
Bake for 15 to 18 minutes—the center should look slightly wet and jiggle a little when you gently shake the pan, but the edges should be just set.
- 13
Remove the cake from the oven and let it cool in the pan for 5 minutes, then run a thin knife around the inside edge to loosen it.
- 14
Place a flat plate or cake cardboard over the pan, then hold the plate and pan together and flip them so the cake slides onto the plate; carefully peel off the parchment paper from the top.
- 15
Dust the cake generously with 1 tablespoon of cocoa powder using a fine-mesh sieve or cocoa shaker, letting the powder fall evenly across the top surface.
- 16
Let the cake cool to room temperature for 10 to 15 minutes before slicing—this helps it hold its shape.
