What Is a Magic Custard Cake?

Magic custard cakes are a genius creation where one batter separates into three luscious layers as it bakes: a firm base, velvety custard in the middle, and a fluffy sponge cake on top. The magic happens in the oven thanks to the precise balance of ingredients and gentle folding technique.

We’ve seen chocolate, vanilla, banana, and strawberry versions—but this Lemon Custard Cake brings a bright, citrusy twist that’s made for summer.

Ingredients You’ll Need To Make Lemon Custard Cake

Here’s everything you need to make this beautiful Lemon Custard Cake from scratch:

4 large eggs, separated, room temperature
¾ cup granulated sugar
½ cup unsalted butter, melted and cooled
1 tsp vanilla extract
¾ cup all-purpose flour
¼ cup freshly squeezed lemon juice
Zest from 2 large lemons
1¾ cups lukewarm milk
Powdered sugar, for dusting

Pro Tip: Fresh lemon juice is key! Bottled lemon juice just won’t give you that vibrant citrus punch.

How to Make Lemon Custard Cake

This desserts recipe is easier than it looks, but precision is key for perfect layers. Follow these steps for the best results:

1. Preheat and Prep

Preheat your oven to 325°F (160°C). Line an 8×8-inch baking pan with parchment paper, leaving overhang on the sides. Lightly grease with cooking spray.

2. Whip the Egg Whites

Using a hand or stand mixer, whip the egg whites to stiff peaks. Set aside.

3. Make the Batter

In another bowl, beat the egg yolks and sugar until pale and fluffy. Mix in the melted butter and vanilla extract until combined.
Add in the flour, mixing until just incorporated. Then whisk in the lemon juice and zest. Slowly pour in the lukewarm milk, mixing until smooth. The batter will be very thin—this is normal!

4. Fold in the Egg Whites

Gently fold the whipped egg whites into the batter using a spatula. Don’t fully combine—small lumps of egg white should remain. These lumps float to the top during baking to form the fluffy sponge layer.

5. Bake

Pour the batter into your prepared pan. Bake for 40–60 minutes, or until the top is golden and lightly firm to the touch. The center should have a slight jiggle.
If it starts to brown too fast, loosely cover with foil.

6. Cool and Serve

Let the cake cool completely at room temperature, then dust with powdered sugar. Slice, serve, and enjoy!

Tips for Perfect Lemon Custard Cake

Use room temperature eggs for better volume and smoother blending.
Don’t overmix when folding in the egg whites—this helps the layers form.
Let it cool completely before slicing to give the custard layer time to set.
Store leftovers in the refrigerator for up to 3 days.

Customize Your Cake

Looking to add a personal twist? Here are a few fun variations to try:

Berry Burst: Fold in fresh raspberries or blueberries for a fruity upgrade.
Coconut Zing: Add shredded coconut to the batter for a tropical flavor.
Lavender Lemon: Infuse with dried lavender or rosemary for a gourmet touch.
Citrus Swap: Try orange or lime juice for a different citrus profile.
Gluten-Free Option: Use a gluten-free all-purpose flour blend.
