Melt-in-Your-Mouth Chocolate Cake Recipe

Yesterday we had a small party at my office to celebrate my company’s fifth anniversary, and our pendaison de crémaillère, which is French for a housewarming party: une crémaillère is a trammel, the metal adjustable hook that was used to hang pots in the fireplace in the days of yore, and the hanging of this essential piece of equipment in a new house was as good an occasion as any to have a village gathering.

Our new offices are located in the south of the 13th arrondissement, close to the Parc Montsouris and the very nice Butte-aux-Cailles area. The street name happens to be Rue Brillat-Savarin, in reference to Jean-Anthelme Brillat-Savarin*, who’s considered the first food writer/critic in history. Cool, huh?

I had offered to bake a cake for the occasion, and used a trusted recipe for fudgy chocolate cake — gâteau au chocolat fondant in French. It is a very easy recipe that does not require a food processor, and like all dark chocolate cakes, it is best made the day before, or at least in the morning if served for dinner.

Edit: Over the years, my way of making this cake has evolved, and I’ve updated the recipe below to reflect that. I now use 180 g of sugar (instead of the original 250 g) and 4 eggs (instead of the original 5). I bake the cake at 180°C (instead of the original 190°C) for slightly longer (25 instead of 20 minutes), and I sprinkle the surface with fleur de sel, which enhances the chocolate flavor and provides tiny jolts of saltiness here and there.

The cake was suitably wolfed down by my appreciative coworkers. It has a nice thin crust, while the inside is 100% melty gooey chocolate goodness. Needless to say, it is pretty rich, so it is best served with something refreshing — ideally, Marie-Laure and Ludo’s fruit salad, but your own fruit salad, fresh strawberries, ice cream and/or whipped cream will be great too.

* Brillat-Savarin published a treatise on the art of dining called “La Physiologie du goût” (“Physiology of taste”) and he’s the one who said “Dis-moi ce que tu manges, je te dirai ce que tu es”, translated as “Tell me what you eat, I will tell you who you are” or “You are what you eat”.

Melt-in-Your-Mouth Chocolate Cake Recipe

Prep Time: 15 minutes

Cook Time: 25 minutes

Total Time: 40 minutes

Makes one 20-cm (8-inch) round cake.

Melt-in-Your-Mouth Chocolate Cake Recipe


  • 200 grams (1 cup minus 2 tablespoons) unsalted butter, diced (substitute almond butter or coconut oil to make this dairy-free)
  • 200 grams (7 ounces) high-quality bittersweet chocolate, roughly chopped
  • 180 grams (1 cup minus 2 tablespoons) unrefined blond cane sugar
  • 4 large eggs
  • 1 rounded tablespoon flour (all-purpose or other, including any gluten-free flour; can be omitted altogether to make this grain-free)
  • fleur de sel or kosher salt, for sprinkling


  1. Preheat the oven to 180°C (350°F). Line a 20-cm (8-inch) round cake pan with parchment paper.
  2. Melt together the butter with the chocolate (in a double-boiler or in the microwave, slowly and for just a few seconds at a time, blending with a spoon between each pass). Transfer to a medium mixing bowl. Add in the sugar, stir with a wooden spoon and let cool a little. Add the eggs one by one, mixing well after each addition. Finally, add in the flour, if using, and mix well.
  3. Pour the batter into the prepared pan, sprinkle the surface lightly with fleur de sel, and put into the oven to bake for 25 minutes, until the center is set.
  4. Transfer to a rack to cool completely. Run a knife around the cake to loosen, then transfer to a serving dish.


  • Like most intensely chocolaty cakes, this cake is best made a day ahead, or in the morning if you serve it for dinner. Cover with plastic wrap, refrigerate, and take it out about an hour before serving.
  • The batter can also be baked in muffin tins lined with muffin liners; reduce the baking time to 15 minutes.
