You can create this rich, fudgy flourless chocolate cake using just a few ingredients. It delivers an intensely chocolate flavor and a melt-in-your-mouth texture, making it an elegant and simple gluten-free dessert for any special occasion.
Preheat your oven to 350°F (175°C). Grease and line the bottom of an 8-inch round springform pan with parchment paper.
Place the chopped chocolate and butter in a heatproof bowl set over a saucepan of simmering water (a double boiler). Heat gently, stirring occasionally, until the mixture is completely smooth. Remove from heat and let it cool slightly, about 5 minutes.
Whisk the granulated sugar and brown sugar into the melted chocolate mixture until combined.
Add the eggs one at a time, beating well after each addition until the batter is thick and glossy. Stir in the vanilla extract and salt.
Pour the batter into the prepared springform pan.
Bake for 30 to 35 minutes. The edges should look set, but the center will still look soft and slightly underdone. This ensures a fudgy texture.
Let the cake cool completely in the pan on a wire rack. The cake will sink in the center as it cools; this is normal for a flourless chocolate cake.
Once cool, carefully release the sides of the springform pan. Dust the top generously with powdered sugar before slicing and serving.
Notes
Use the best quality bittersweet chocolate you can find; since this recipe has few ingredients, the chocolate flavor is central.
For an extra decadent finish, you can top the cooled cake with a simple chocolate ganache.
This cake tastes best when served at room temperature or slightly chilled.
