Creamy Dark Chocolate Cake
Few ingredients, no compromises: this cake is pure chocolate—dense, creamy, with a thin crust hiding a soft, melt-in-your-mouth heart.
Ingredients (for 8 people)
- 250 g dark chocolate (at least 60% cocoa)
- 100 g of butter
- 4 medium eggs
- 150 g of granulated sugar
- 1 heaped tablespoon of 00 flour or potato starch
- A few drops of flavoring to taste (vanilla, rum, Grand Marnier)
- Powdered sugar to taste for decoration
- Fresh whipped cream to taste (optional, for serving)
Preparation
— Melted chocolate —
1. Preheat the oven. Preheat the oven to 180°C (350°F) and line a 20–22 cm (8–9 in) round baking pan with parchment paper. This is the perfect time to do this: the oven should already be at the right temperature when the cake is ready to go in.
2. Melt the butter and chocolate. Break the dark chocolate into pieces and place it in a small saucepan with the cubed butter. Melt in a double boiler, stirring with a spatula until smooth, glossy, and free of lumps. Alternatively, you can microwave on low power, heating in 30-second increments, stirring after each 30-second increments to avoid burning the chocolate. Let cool—the mixture should not be boiling when you add the eggs.
3. Add the flour. Add the sifted flour (or starch) to the lukewarm chocolate, mixing well with a spatula until smooth. The flour in this recipe is almost symbolic—very little, just that gram of structure that distinguishes a cake from a cream. If you prefer an even darker, gluten-free consistency, opt for potato starch.
— The whipped eggs —
4. Beat the egg yolks with the sugar. Carefully separate the yolks from the whites, taking care not to leave any traces of yolk in the egg whites—even a small amount of fat will prevent the egg whites from whipping. Using an electric mixer, beat the egg yolks with half the sugar for at least 5 minutes: the mixture should become light, frothy, and almost double in volume. Add the drops of flavoring or your chosen liqueur and continue mixing briefly.
5. Add the chocolate to the egg yolks. Pour the melted, warm chocolate into the egg yolk mixture, folding it in with a spatula using firm, but not abrupt, movements. The result will be a thick, fragrant mixture that's a deep brown, almost black.
6. Whip the egg whites until stiff. In a perfectly clean and dry bowl, beat the egg whites with an electric mixer, gradually adding the remaining sugar as soon as the first bubbles begin to form. Continue beating until the egg whites form stiff, glossy peaks. If you turn the bowl upside down, they should not move.
— Assembly and cooking —
7. Incorporate the egg whites. Pour the beaten egg whites into the chocolate mixture in two or three batches. Using a soft spatula, fold in slowly from the bottom up, rotating the bowl between each turn. The goal is not to deflate the egg whites: every incorporated air bubble is what gives the cake its creamy, not brick-like, texture. Mix patiently until the mixture is smooth and free of white streaks.
8. Pour and bake. Carefully transfer the mixture to the prepared pan, smoothing the surface with a spatula without pressing. Bake at 180°C (350°F) for 25–30 minutes. The cake is ready when the surface appears dry and slightly ridged, but a toothpick inserted into the center comes out with a few moist crumbs attached—not completely clean, as the center must remain melt-in-the-mouth.
9. Cooling and decoration. Remove from the oven and let cool completely in the pan before unmold: it's too fragile to move while hot. Once cooled, dust generously with powdered sugar and, if desired, serve with dollops of fresh whipped cream.
Important notes
- Surface cracks are normal: If cracks form during baking, don't worry—this is a characteristic of this cake, a direct result of its softness and the very small amount of flour. The powdered sugar will elegantly hide them.
- Quality dark chocolate: With so few ingredients, the quality of the chocolate makes all the difference. Use a dark chocolate with at least 60% cocoa solids, preferably 70%. Avoid low-end supermarket bars.
- Flour or starch? Potato starch makes the cake even softer and makes it naturally gluten-free. 00 flour gives it a slightly firmer texture. Both work well.
- Customizable cooking: For a meltier, almost coulant-like center, remove from the oven after 22–23 minutes. For a more firm brownie-like consistency, bake for 30 minutes.
- Conservation: It can be stored at room temperature under a glass dome for 2–3 days. It hardens in the refrigerator: if you refrigerate it, bring it back to room temperature at least 30 minutes before serving.
- Recommended flavors: A few drops of vanilla extract is the classic choice. For a more adult version, a spoonful of dark rum, Grand Marnier, or espresso enhances and complexifies the chocolate's flavor profile.
