Ingredients
Wet Ingredients
- 1/2 cup unsalted butter, melted and cooled to room temperature
- 2 cups milk, warmed to lukewarm temperature
- 4 eggs, yolks and whites separated
- 1 tablespoon purified water
- 2 teaspoons pure vanilla extract
Dry Ingredients
- 1 and 1/4 cups (150 g) confectioners’ sugar, sifted
- 1 cup (115 g) all-purpose flour, sifted
For Garnish
- Confectioners’ sugar, for dusting
Instructions
- Preheat Oven: Preheat your oven to 325°F (163°C) to prepare for baking the custard cake perfectly.
- Prepare Baking Dish: Lightly coat an 8×8 inch baking dish with non-stick baking spray to prevent sticking, then set it aside.
- Whip Egg Whites: In a clean mixing bowl, whisk the egg whites vigorously until stiff peaks form, indicating they are firm and can hold shape. Set aside.
- Mix Egg Yolks and Sugar: In another bowl, combine egg yolks with sifted confectioners’ sugar and beat until the mixture is pale yellow and creamy.
- Add Butter and Water: Slowly add melted butter and the tablespoon of purified water into the yolk mixture, mixing for about two minutes to ensure a smooth blend.
- Incorporate Flour: Gradually add the sifted all-purpose flour, mixing thoroughly to remove lumps and achieve a smooth batter.
- Add Milk and Vanilla: Slowly pour in the lukewarm milk and vanilla extract while continuously mixing to form a homogeneous batter.
- Fold in Egg Whites: Gently fold the whipped egg whites into the batter in three portions, being careful not to deflate the whites to maintain airiness.
- Bake the Cake: Pour the batter into the prepared baking dish. Bake in the preheated oven for 40-60 minutes, checking from 40 minutes onward. If the top browns too quickly, cover loosely with aluminum foil to prevent burning.
- Cool and Garnish: Remove the cake from the oven and allow it to cool to room temperature. Dust lightly with confectioners’ sugar before serving for an elegant finish.
Notes
- Ensure the egg whites are whipped to stiff peaks for the best texture separation in the custard cake.
- Use lukewarm milk to avoid curdling when mixing with eggs and butter.
- Watch the cake closely near the end of baking to avoid over-browning or drying out.
- Folding egg whites gently is key to maintaining the cake’s lightness.
- This cake can be served chilled or at room temperature, depending on your preference.
