Gâteau Magique (Magic Custard Cake)
One serving has 212 kcal and 5 g protein. Ready in 260 minutes.

- Preparation: 200 min
- Cooking: 60 min
- Makes: 1 serving (92.3 g)
- Difficulty: Medium
- Diets: Vegetarian
- Contains: alcohol, dairy, egg, gluten
Ingredients
- 16.5 g Eggs, separated
- 12.5 g Caster sugar
- 10.5 g Butter, melted and cooled
- 9.5 g Plain flour
- 42 g Whole milk
- 0.4 g Vanilla extract
- 0.1 g Salt
- 0.8 g Icing sugar (to dust)
Method
- Heat the oven to 150 °C (300 °F) and line a 20 cm square cake tin with baking paper, letting it come up the sides. Warm the milk with the vanilla until lukewarm, not hot.
- Whisk the egg yolks with the caster sugar until pale and thick, then whisk in the melted butter. Whisk in the flour until smooth, then pour in the warm milk a little at a time, whisking, to make a very thin batter.
- In a clean bowl, whisk the egg whites with the salt to stiff peaks. Fold them into the batter in three batches, gently, with a whisk: the batter will stay runny with small lumps of white floating on top, which is right.
- Pour it into the tin and bake for 50-60 minutes, until the top is golden and the cake wobbles only slightly in the middle when you shake the tin.
- Leave it to cool in the tin, then chill it for at least 3 hours, until set: as it bakes it separates into a dense base, a layer of custard and a light sponge on top.
- Lift it out by the paper, dust the top with the icing sugar and cut it into 12 pieces with a sharp knife wiped between cuts. Makes 12 pieces; the amounts are for one serving, so multiply every ingredient by 12 for the whole cake.
