Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
4 large eggs, room temperature and separated
3/4 cup granulated sugar
1/2 cup unsalted butter, melted and slightly cooled
1 teaspoon vanilla extract
3/4 cup all-purpose flour
2 cups lukewarm milk
1/4 cup freshly squeezed lemon juice
1 tablespoon lemon zest
1/4 teaspoon salt
Directions
Start by preheating your oven to 325°F (160°C). Lightly grease an 8×8-inch baking dish or line it with parchment paper for easy removal.
Separate the eggs carefully, placing the yolks in one bowl and the whites in another. Using a mixer, beat the egg whites until stiff peaks form, then set them aside.
In a separate large bowl, whisk together the egg yolks and sugar until the mixture becomes pale and slightly thickened. Slowly add the melted butter and vanilla extract, mixing until smooth and well combined.
Sift in the flour and mix gently until fully incorporated. Gradually pour in the lukewarm milk while continuing to whisk. The batter will be thin, which is normal for this recipe.
Add the fresh lemon juice, lemon zest, and salt, and stir until everything is evenly combined.
Gently fold the beaten egg whites into the batter in batches. Do this carefully to keep as much air in the mixture as possible. The batter will look slightly lumpy and airy.
Pour the mixture into the prepared baking dish. Place the dish in the oven and bake for about 45 to 55 minutes, or until the top is lightly golden and set while the center remains slightly jiggly.
Remove the cake from the oven and allow it to cool completely before slicing. The layers will become more defined as it cools. For best results, chill it in the refrigerator for a couple of hours before serving.
Servings and timing
This recipe makes about 9 servings. Preparation time takes approximately 20 minutes, while baking takes around 50 minutes. Including cooling time, the total time is about 2 hours and 10 minutes.
Variations
You can experiment with different citrus flavors by replacing lemon juice with lime or orange juice for a slightly different taste. Adding a light dusting of powdered sugar on top before serving enhances both appearance and sweetness.
For a richer flavor, you can substitute part of the milk with cream. If you prefer a more intense citrus profile, increase the lemon zest slightly.
You can also add fresh berries such as blueberries or raspberries to the batter for a fruity twist that pairs beautifully with the custard texture.
Storage/Reheating
Store the lemon custard cake in an airtight container in the refrigerator for up to 3 days. Because of its custard layer, it is best kept chilled.
If you prefer it slightly warm, allow it to sit at room temperature for about 15–20 minutes before serving. Avoid reheating in the microwave, as this may alter the delicate texture of the custard layers.
