Ingredients and Preparation

Here’s what you will need to bring this enchanting dessert to life:

Ingredients:

• 1/2 cup (115 g) unsalted butter, melted and slightly cooled
• 1 1/4 cups (250 g) granulated sugar
• 4 large eggs, separated
• Zest of 1 lemon
• 1/4 cup (60 ml) fresh lemon juice
• 1 teaspoon vanilla extract
• 1/2 cup (65 g) all-purpose flour
• 1/4 teaspoon salt
• 1 1/4 cups (300 ml) whole milk, at room temperature
• Powdered sugar, for dusting

The key to success begins with preparation. Make sure to use fresh lemons for both zest and juice to achieve the vibrant citrus notes that define this cake. Room temperature ingredients are also critical, as they help create a smooth, cohesive batter and an even bake.

Grease and line your baking dish properly to ensure easy removal. Using parchment paper with an overhang makes lifting the finished cake a breeze, preserving its delicate layers and beautiful appearance.

Step-by-Step Instructions

Preheat the Oven:
Begin by preheating your oven to 325°F (160°C). Prepare an 8×8-inch (20×20 cm) baking dish by greasing it lightly and lining it with parchment paper, allowing some overhang on the sides.

Prepare the Egg Whites:
In a clean, dry mixing bowl, beat the egg whites on high speed using an electric mixer. Continue beating until stiff peaks form. This means the egg whites should stand tall when the beaters are lifted and hold their shape firmly without drooping. Set the bowl aside while you prepare the rest of the batter.

Create the Batter:
In a separate large bowl, combine the egg yolks and granulated sugar. Beat them together until the mixture becomes pale in color and thick in texture, a sign that air has been properly incorporated.

Gradually add the melted butter, lemon zest, lemon juice, and vanilla extract to the egg yolk mixture, beating until everything is well combined and smooth.

Sift the flour and salt together, then add them into the wet ingredients. Mix carefully until just combined, ensuring no lumps remain.

Slowly pour in the whole milk while continuing to mix on low speed. The batter will become quite thin, which is exactly what you want for this recipe.

Incorporate the Egg Whites:
Divide the whipped egg whites into three portions. Gently fold each portion into the batter, one at a time, using a spatula. The batter will look airy and slightly uneven, but resist the urge to overmix. Maintaining the lightness of the whipped egg whites is essential to achieving the three distinct layers during baking.

Bake the Cake:
Pour the airy batter into the prepared baking dish. Bake for 40 to 50 minutes. The top should develop a light golden color, and the cake should jiggle slightly when gently shaken. Avoid overbaking, as this could dry out the custard layer.

After baking, let the cake cool completely in the pan. This resting period allows the layers to set properly.

Serve:
Once cooled, dust the top generously with powdered sugar. Slice into squares and serve as is, or dress it up with a dollop of freshly whipped cream and a handful of berries for an extra flourish.

Beginner Tips and Notes

Room Temperature Ingredients:
Bringing your eggs, milk, and butter to room temperature ensures a smoother batter and more even baking. Cold ingredients can cause the batter to seize or separate.

Fresh Lemon Is Essential:
Bottled lemon juice cannot replicate the brightness of fresh lemon juice. Be sure to zest only the bright yellow outer layer of the lemon. Avoid the white pith underneath, as it can introduce bitterness into the cake.

Handling the Batter:
The thin consistency of the batter might seem unusual if you are used to thicker cake batters. Do not be alarmed; this liquid-like texture is necessary for the cake to naturally separate into its three delightful layers during baking.

Folding Techniques:
When folding in the egg whites, use a light hand. Overmixing can deflate the batter and result in a denser, less magical cake.

Storage:
This cake should be stored in the refrigerator if not eaten immediately. It will keep for up to three days. For the best texture and flavor, allow slices to sit at room temperature for about 15 minutes before serving if chilled.

Serving Suggestions

This cake is beautiful in its simplicity but can be elevated in several ways depending on the occasion.

With Fresh Berries:
Add a pop of color and a complementary tartness by serving the cake with raspberries, blueberries, or blackberries. A mixed berry medley creates an especially vibrant presentation.

With Whipped Cream:
A soft cloud of lightly sweetened whipped cream enhances the richness of the custard layer without overpowering the lemon flavor.

With Lemon Curd:
For the ultimate citrus experience, serve slices of the cake with a spoonful of lemon curd on the side. The intensified lemon flavor pairs beautifully with the mellow custard.

For a Brunch Spread:
Include Lemon Custard Cake on a brunch table alongside scones, croissants, and fruit salad. Its lightness balances the heartier fare typically found at brunch.

For a Tea Party:
Offer small squares of the cake as part of an elegant tea spread. Its refined texture and flavor make it a natural match for delicate teas like Earl Grey or chamomile.
