How to Make Lemon Custard Cake

Making lemon custard cake is simpler than it looks. The magic happens in the oven, where the batter separates into two distinct layers—a soft, fluffy sponge on top and a smooth, creamy custard at the bottom. Follow these steps to get that perfect texture every time.

Step 1: Preheat and Prepare

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 later.

Step 2: Separate the Eggs

Carefully separate the eggs, placing the yolks in one bowl and the whites in another. Make sure there’s no trace of yolk in the whites—this helps them whip up properly later.

Step 3: Mix the Yolks and Sugar

In a large mixing bowl, whisk the egg yolks and granulated sugar together until the mixture becomes pale and slightly thick. This step helps incorporate air, making the cake light and fluffy.

Step 4: Add Butter and Dry Ingredients

Stir in the melted butter, lemon zest, and vanilla extract. Gradually sift in the flour and salt, mixing until well combined.

Step 5: Add the Milk and Lemon Juice

Slowly pour in the lukewarm milk and fresh lemon juice, whisking constantly to keep the batter smooth. The mixture will be quite thin at this stage, but don’t worry—that’s what gives the cake its custard-like texture.

Step 6: Whip the Egg Whites

Using a hand or stand mixer, beat the egg whites until stiff peaks form. This means when you lift the beaters, the egg whites should hold their shape.

Step 7: Fold in the Egg Whites

Gently fold the whipped egg whites into the batter, using a spatula to combine them in three additions. The batter will look lumpy, but that’s completely normal—those fluffy bits of egg white help create the cake’s light top layer.

Step 8: Bake

Pour the batter into your prepared baking dish and bake for about 40–45 minutes, or until the top is golden and slightly firm to the touch. The cake may have a slight jiggle in the center—that’s the custard layer underneath!

Step 9: Cool and Serve

Let the cake cool in the pan for about 15 minutes, then transfer it to a wire rack to cool completely. Once cooled, dust the top with powdered sugar for a beautiful finishing touch.

Helpful Tips

• Room temperature ingredients – Let your eggs and milk come to room temperature before starting. This helps the batter mix more evenly.
• Use fresh lemon juice – Bottled lemon juice won’t give the same bright, fresh flavor.
• Be gentle when folding in egg whites – Overmixing can deflate them, resulting in a denser cake.
• Check for doneness – The top should be golden, and the cake should have a slight wobble in the center.

Frequently Asked Questions

Why did my lemon custard cake sink in the middle?

A slight dip in the center is normal because of the custard layer. However, if it collapses too much, it might be underbaked. Make sure to bake until the top is golden and set.

Can I make this cake ahead of time?

Yes! You can bake it a day in advance and store it in the fridge. The custard layer will firm up slightly, making it even easier to slice.

How do I serve lemon custard cake?

This cake is delicious on its own but can be served with fresh berries, a dollop of whipped cream, or a light dusting of powdered sugar.

Can I freeze this cake?

Lemon custard cake is best enjoyed fresh, but you can freeze it for up to a month. Wrap it tightly in plastic wrap and store it in an airtight container. Let it thaw in the fridge before serving.
