Ingredients
Scale
- 1/2 cup unsalted butter, melted and cooled to room temperature: The butter adds richness to the cake, creating a moist texture. It also helps in forming the custard layer.
- 2 cups milk, warmed to lukewarm temperature: The milk is the foundation of the custard layer. Lukewarm milk helps the batter come together smoothly.
- 1 and 1/4 cups (150g) confectioners’ sugar, sifted: Powdered sugar gives the cake the perfect amount of sweetness, and sifting ensures no lumps in the batter.
- 4 large eggs, yolks and whites separated: The egg yolks help form the structure of the cake, while the egg whites are whipped to create the light, airy texture on top.
- 1 tablespoon purified water: A small amount of water helps to incorporate the butter into the batter smoothly.
- 1 cup (115g) all-purpose flour, sifted: Flour provides the structure to the cake, allowing the batter to rise properly and form distinct layers.
- 2 teaspoons pure vanilla extract: This is the key to the dessert’s aromatic flavor that will fill your kitchen as it bakes.
- Confectioners’ sugar, for garnishing: A light dusting of powdered sugar adds a beautiful finishing touch and enhances the cake’s sweetness.
Instructions
- Prepare the Oven and Baking Dish:
Preheat your oven to 325°F (163°C). Lightly grease an 8×8-inch baking dish with non-stick spray to ensure the cake comes out easily after baking. Set the dish aside while you prepare the batter. - Whip the Egg Whites:
In a clean mixing bowl, whisk the egg whites until stiff peaks form. This step is crucial as it will give the cake its light, airy top layer. Once the egg whites are ready, set them aside. - Mix the Egg Yolks and Sugar:
In a separate bowl, combine the egg yolks and sifted confectioners’ sugar. Beat them together until the mixture turns a pale yellow color, which should take about 2 minutes. This will form the base of the cake’s structure. - Add the Butter and Water:
Pour the cooled, melted butter and purified water into the egg yolk mixture. Beat the mixture for another 2 minutes, ensuring everything is fully combined. - Incorporate the Flour:
Sift the flour into the mixture to avoid any lumps. Stir until fully combined, forming a smooth batter. - Add Milk and Vanilla:
Gradually pour in the lukewarm milk and vanilla extract, mixing gently until everything is fully integrated. You should now have a smooth, slightly runny batter. - Fold in the Whipped Egg Whites:
Gently fold the whipped egg whites into the batter in three parts, being careful not to deflate the air you’ve incorporated into the whites. This is what helps form the three layers during baking, so take your time and ensure the mixture is well combined but not overmixed. - Bake the Cake:
Pour the batter into the prepared baking dish and place it in the preheated oven. Bake for 40-60 minutes, depending on your oven. Start checking the cake at the 40-minute mark. The surface should turn golden brown. If it’s browning too quickly, cover it with aluminum foil. The cake is done when the top is firm and a toothpick inserted into the center comes out clean. - Cool and Garnish:
Remove the cake from the oven and allow it to cool to room temperature. Once cooled, lightly dust the top with powdered sugar for a beautiful, elegant finish.

- Dairy-Free Version: Swap the milk for a plant-based alternative such as almond milk or coconut milk, and use dairy-free butter to make this recipe suitable for those who are lactose intolerant or following a dairy-free diet.
- Flour Alternatives: For a gluten-free option, you can use a gluten-free all-purpose flour blend, ensuring it includes xanthan gum for structure.
- Flavor Variations: While vanilla is the classic flavor for this cake, you can experiment with other extracts like almond, coconut, or even lemon. Just be sure to adjust the amount to suit your taste.
- Serving Suggestions: This cake is perfect as a standalone dessert, but you can also pair it with a scoop of vanilla ice cream or fresh berries for added flavor and color. It’s also delightful when served with a drizzle of caramel or chocolate sauce for an extra touch of decadence.
