Gâteau Magique au Chocolat

Ingredients

• 0.5 cup unsalted butter (Melted and cooled slightly, plus extra for greasing the pan)
• 4 large eggs (At room temperature, separated)
• 0.75 cup granulated sugar (Divided as needed for the yolk mixture and egg whites)
• 0.333 cup unsweetened cocoa powder (Natural or Dutch-processed cocoa may be used; Dutch-processed gives a darker color)
• 0.75 cup all-purpose flour (Sifted if lumpy)
• 2 cup whole milk (At room temperature)
• 2 tsp vanilla extract
• 0.25 tsp fine salt
• unsweetened cocoa powder (For dusting before serving)

Steps

1. 1

   Bring the eggs and milk to room temperature before beginning. Position a rack in the center of the oven and heat the oven to 325°F (165°C). Grease and line an approximately 8-inch square baking pan with parchment, leaving an overhang for lifting out the cake.

2. 2

   Melt the butter and set it aside to cool slightly. Keep it fluid but not hot enough to cook the egg yolks.

3. 3

   Separate the eggs, placing the yolks in a large bowl and the whites in a clean mixing bowl. Add the sugar to the yolks and whisk until the mixture is pale and smooth.

4. 4

   Whisk the melted butter into the yolk mixture in a thin stream. Add the vanilla and salt, then whisk until evenly combined.

5. 5

   Add the cocoa powder and flour to the yolk mixture and whisk until no dry streaks remain. The mixture will be thick at this stage.

6. 6

   Gradually whisk in the room-temperature milk until the batter becomes very thin and smooth. Do not be concerned by its watery consistency; this is necessary for the layers to form.

7. 7

   Beat the egg whites in a clean bowl until they form stiff peaks. The whites should hold their shape when the beaters are lifted.

8. 8

   Add the beaten whites to the thin chocolate batter. Fold gently with a spatula just until large streaks of white disappear, leaving some small floating clumps of egg white. Do not fully homogenize the batter.

9. 9

   Pour the batter into the prepared pan and gently smooth the surface. Bake for about 1½ hours, until the top is puffed and set, the center has only a slight jiggle, and the cake has separated into its characteristic layers.

10. 10

    Transfer the cake to a rack and cool completely in the pan before slicing. Cooling allows the custard and pudding layers to firm and prevents the cake from collapsing or becoming difficult to cut.

11. 11

    Use the parchment overhang to lift out the cake. Cut into squares, dust lightly with cocoa powder, and serve at room temperature.

Notes

The supplied page excerpt is access-restricted and does not expose the author's ingredient list or detailed instructions; quantities and procedure above are therefore a low-confidence reconstruction of the classic gâteau magique method. Do not use cold eggs or milk. Leftovers keep refrigerated for about one day; bring them to room temperature and dust with cocoa before serving.
