What Makes This Lemon Custard Cake So Special?
Unlike traditional cakes, a Lemon Custard Cake uses a unique mixing method. Whipped egg whites are folded into a thin, custard-like batter. In the oven, the heavier ingredients sink to form the custard layer, while the light egg whites rise to create a delicate sponge cake topping. It’s a simple technique with a truly magical outcome.

Key Ingredients for Lemon Custard Cake
The beauty of this recipe lies in its simplicity. Here’s what you’ll need:
- Eggs: You’ll need to separate them. The yolks add richness to the custard, while the whites are whipped to provide lift and create the cake layer. Ensure they are at room temperature for the best results.
- Granulated Sugar: Provides the perfect amount of sweetness to balance the tart lemon.
- Unsalted Butter: Use melted and slightly cooled butter for a rich, tender crumb.
- All-Purpose Flour: Just a small amount is needed to give the cake structure.
- Milk: Whole milk works best for the creamiest custard. Make sure it’s lukewarm.
- Lemon: You’ll use both the zest and the juice for a powerful, fresh lemon flavor.
- Salt: A pinch of salt enhances all the other flavors.
Step-by-Step Baking Instructions
Follow these simple steps to create your own magical Lemon Custard Cake.
- Prep Your Station: Preheat your oven to 325°F (160°C). Grease and flour an 8×8 inch baking pan.
- Combine Yolks and Sugar: In a large bowl, whisk the egg yolks with the granulated sugar until the mixture becomes pale and creamy.
- Add Wet Ingredients: Whisk in the melted butter, lemon zest, and lemon juice until fully combined.
- Incorporate Flour and Milk: Gradually whisk in the flour and salt, alternating with the lukewarm milk. Mix until the batter is smooth. It will be very thin, like a crepe batter.
- Whip Egg Whites: In a separate, clean bowl, use an electric mixer to beat the egg whites until stiff peaks form. Be careful not to over-whip.
- Fold and Combine: Gently fold about one-third of the whipped egg whites into the batter to lighten it. Then, carefully fold in the remaining egg whites until just combined. Do not overmix; a few streaks are okay.
- Bake the Cake: Pour the batter into your prepared pan. Bake for 40-50 minutes, or until the top is golden brown and the center is set. The center should still have a slight wobble when gently shaken.
- Cool Completely: Let the cake cool completely in the pan before slicing and serving. This allows the custard layer to fully set. Dust with powdered sugar for a beautiful presentation.
Expert Tips for Perfect Layer Separation
To guarantee that magical two-layer result, keep these tips in mind.
- Room Temperature Ingredients: Using room temperature eggs and lukewarm milk helps the batter emulsify properly.
- Don’t Overmix: When folding in the egg whites, be gentle! Overmixing will deflate the whites, preventing the cake layer from rising properly.
- Properly Whipped Whites: Ensure your egg whites are whipped to stiff peaks. This is crucial for creating the light, airy cake topping.
- Cool it Down: Don’t rush the cooling process. The cake needs time to set completely. Slicing it too early can result in a runny custard.

Frequently Asked Questions
Yes, this cake is perfect for making ahead. It needs to cool completely to set properly, so we recommend making it at least 4-6 hours in advance. It can be stored, covered, in the refrigerator for up to 3 days.
For the best, brightest flavor, we highly recommend using freshly squeezed lemon juice. Bottled juice can sometimes have a dull or slightly bitter taste that will be noticeable in the final dessert.
The top of the cake will be a light golden brown and feel firm to the touch. The center should be set, but it will still have a slight jiggle or wobble when you gently shake the pan. This indicates the custard layer underneath is perfectly cooked.
It has two distinct textures in one dessert! The top layer is a light, airy, and delicate sponge cake, while the bottom layer is a smooth, rich, and creamy lemon custard, similar to a lemon pudding.
The most common reasons are overmixing the batter after adding the egg whites, which deflates them, or not whipping the egg whites to stiff peaks. Gentle folding is key to keeping the air in the batter, which allows the layers to form during baking.
