Ingredients You’ll Need

This cake is proof that a handful of well-balanced ingredients can create a dessert with bakery-level texture and flavor.

One of the things I love about this recipe is that it uses simple pantry ingredients. You probably already have most of them in your kitchen.

Base Ingredients:

• 4 eggs, separated
• 3/4 cup sugar
• 1/2 cup unsalted butter, melted
• 3/4 cup all-purpose flour
• 2 cups milk, lukewarm
• 1/4 cup fresh lemon juice
• 1 tablespoon lemon zest
• 1 teaspoon vanilla extract
• 1/4 teaspoon salt

Optional Add-ins:

• 1/2 teaspoon almond extract
• 2 tablespoons powdered sugar (for dusting)
• 1 tablespoon lemon syrup
• 1/2 cup fresh berries
• 1 tablespoon whipped cream

Step-by-Step Instructions

Step 1: Prepare the Batter Base

Start by separating the egg yolks and whites into two bowls. In the yolk bowl, whisk sugar and melted butter until smooth and pale. Add lemon juice, zest, and vanilla extract, mixing thoroughly. Gradually add flour and mix until smooth. Slowly pour in lukewarm milk while whisking to create a thin batter. This consistency is essential—it allows the cake to separate into layers during baking, forming both sponge and custard textures naturally.

Step 2: Whip the Egg Whites

In a clean bowl, beat egg whites with a pinch of salt until soft peaks form. This step is crucial for achieving the light sponge layer. Gently fold the whipped egg whites into the batter in batches, using a spatula. Avoid overmixing; the batter should remain slightly airy and uneven. These air pockets will expand during baking, helping create the signature layered structure of the custard cake.

Step 3: Bake the Cake

Preheat your oven to 160°C (320°F). Pour the batter into a greased baking dish. Bake for 45–50 minutes until the top is lightly golden and set. The center should still have a slight jiggle, indicating the custard layer is intact. Avoid overbaking, as it can dry out the cake. Allow it to cool completely in the pan to help the layers settle and firm up properly.

Step 4: Cool and Serve

Once cooled, dust the top with powdered sugar for a clean finish. Slice gently to reveal the layers—light sponge on top and silky custard beneath. Serve chilled or at room temperature. Garnish with fresh berries or a light drizzle of lemon syrup if desired. Proper cooling enhances both flavor and texture, making each slice visually appealing and delicious.

Frequently Asked Questions

Why does this cake separate into layers during baking?
The batter’s thin consistency and the incorporation of whipped egg whites allow natural separation during baking. The heavier custard settles at the bottom while the airy sponge rises, creating the signature dual-layer texture without requiring separate preparation.

Can I make this cake ahead of time?
Yes, this cake can be made a day in advance. In fact, chilling it overnight enhances the texture and flavor. Store it properly in the refrigerator and serve slightly chilled or at room temperature for the best results.

What pan size works best for this recipe?
An 8×8-inch square baking dish works best for even thickness and proper layering. Using a larger pan may result in thinner layers, while a smaller pan can affect baking time and consistency, so it’s best to follow recommended sizing.
