Custard Layer Cake Recipe
Ingredients
- 1/2 cup (113g) unsalted butter, melted and slightly cooled
- 2 cups (480ml) milk, lukewarm
- 4 eggs, separated
- 4 drops white vinegar
- 1 1/4 cups (150g) confectioner’s sugar
- 1 tablespoon (15ml) water
- 1 cup (125g) all-purpose flour
- 1 teaspoon (5ml) vanilla extract
- Extra confectioner’s sugar, for dusting
Instructions
1. Preheat and Prepare
- Preheat your oven to 325°F (163°C).
- Grease an 8″x8″ (20cm) baking dish with butter and set it aside.
2. Prepare the Ingredients
- Melt the butter and allow it to cool slightly.
- Warm the milk until lukewarm. It should feel warm to the touch but not hot.
3. Whip Egg Whites
- In a clean, grease-free bowl, whip the egg whites with 4 drops of white vinegar using an electric mixer. Whip until stiff peaks form, then set aside.
4. Mix Egg Yolks and Sugar
- In another bowl, beat the egg yolks and confectioner’s sugar until pale and creamy.
- Add the melted butter and water, then mix for about 2 minutes until smooth.
5. Incorporate the Dry Ingredients
- Gradually add the flour to the egg yolk mixture, mixing until fully combined.
6. Combine Wet Ingredients
- Slowly pour in the lukewarm milk and vanilla extract, stirring continuously until the batter is smooth and runny.
7. Fold in Egg Whites
- Gently fold the whipped egg whites into the batter in thirds, using a spatula. Be careful to maintain the airiness for a fluffy top layer. Fold until no streaks of egg whites remain, but do not overmix.
8. Bake the Cake
- Pour the batter into the prepared baking dish. (Note: The batter will be very runny—this is normal.)
- Bake for 45-60 minutes or until the center is slightly jiggly but set.
- If the top browns too quickly, loosely cover the pan with aluminum foil and continue baking.
9. Cool and Dust
- Allow the cake to cool completely in the pan. Refrigerate for faster cooling.
- Once chilled, dust generously with confectioner’s sugar before slicing and serving.
Tips and Tricks
- Egg Whites: Ensure all utensils are clean and grease-free before whipping egg whites, as any grease can prevent them from forming peaks.
- Folding Technique: Fold egg whites gently to retain air and achieve the cake’s signature layered texture.
- Cooling Time: Proper cooling is essential for the custard to set fully. Avoid cutting the cake while it’s still warm.
- Serving: Serve chilled or at room temperature for the best texture and flavor.
Storage
- Store leftover cake in an airtight container in the refrigerator for up to 3 days.
- For longer storage, freeze individual slices by wrapping them in plastic wrap and placing them in a freezer-safe container. Thaw in the fridge before serving.
FAQs
Q: Can I use salted butter instead of unsalted?
A: Yes, but reduce any additional salt in the recipe to avoid overpowering flavors.
Q: My custard layer is too soft. What went wrong?
A: Ensure you baked the cake long enough. The center should jiggle slightly but still feel set. Cooling is also critical to firm up the custard layer.
Q: Can I make this cake gluten-free?
A: Absolutely! Substitute the all-purpose flour with a gluten-free blend that includes xanthan gum for structure.
Q: Can I double the recipe?
A: Yes! Use a larger pan, like a 9″x13″ baking dish, and adjust the baking time accordingly.
Q: Can I add flavor variations?
A: Yes, you can mix in a teaspoon of lemon zest, almond extract, or orange zest for a unique twist.
