Ingredients You’ll Need
Simple, fresh, and straightforward—that’s the beauty of this Lemon Custard Cake Recipe’s ingredients list. Each component plays a vital role in building the cake’s rich flavor and luscious texture, blending creamy, tangy, and sweet notes into one irresistible treat.
- 1/2 cup unsalted butter, softened: Adds richness and a tender crumb for that melt-in-your-mouth sensation.
- 3/4 cup granulated sugar: Sweetens perfectly without overpowering the lemon’s brightness.
- 3 large eggs, separated: The yolks enrich the custard while the whites create that airy sponge layer on top.
- 1 tablespoon lemon zest: The zest packs intense lemon aroma and flavor that truly awakens the senses.
- 1/3 cup fresh lemon juice: Freshly squeezed juice delivers natural tartness and brightness to balance the sweetness.
- 1/3 cup all-purpose flour: Just enough to create structure while keeping the cake soft and delicate.
- 1/4 teaspoon salt: Enhances overall flavor, making the lemon pop even more.
- 1 1/4 cups whole milk: Adds creaminess to the custard base and keeps the cake moist.
- Powdered sugar, for dusting: A light dusting gives the finished cake an elegant, inviting look.
How to Make Lemon Custard Cake Recipe
Step 1: Prepare Your Pan and Oven
Start by preheating your oven to the perfect 350°F (175°C) to ensure even baking. Grease and lightly flour an 8×8-inch baking dish or any similar-sized pan so your cake can easily release after baking. This step might seem small, but it’s essential for flawless results.
Step 2: Cream Butter and Sugar
In a large bowl, cream the softened butter and granulated sugar together until the mixture becomes light and fluffy. This process helps to incorporate air that will lighten the texture of your cake later—plus, it blends the sweetness and fat so your cake bakes evenly and tenderly.
Step 3: Add Egg Yolks, Lemon Zest, and Juice
Next, beat in the egg yolks one at a time, making sure each is fully incorporated before adding the next. Stir in the fresh lemon zest and juice, which bring that unmistakable lemon punch. The combined fats and acidity create a luscious, tangy custard base that will be the heart of this cake.
Step 4: Combine Dry Ingredients and Milk
Sift the all-purpose flour and salt into your mixture and fold gently until just combined. Then, slowly stir in the whole milk to create a smooth batter that’s neither too thick nor too runny—this balance is key to achieving that dreamy custard consistency beneath the sponge layer.
Step 5: Whip Egg Whites and Fold Gently
In a separate clean bowl, whip the egg whites until soft peaks form—this means the peaks will gently hold shape but still droop slightly. Carefully fold the whites in batches into the lemon batter without deflating the airy volume. This delicate step ensures your cake will have a light sponge on top, setting the stage for the creamy custard below.
Step 6: Bake Until Golden and Set
Pour the prepared batter into your baking pan and place it in the oven. Bake for about 35 to 40 minutes, or until the top is a beautiful light golden color and the center is just set. The magic here is that as the cake bakes, it naturally separates into two layers without any fuss, creating that signature Lemon Custard Cake Recipe texture.
Step 7: Cool and Finish
Once baked, let the cake cool completely in the pan. Cooling is crucial because it allows the custard to fully set beneath the sponge layer. Just before serving, dust generously with powdered sugar to add a final touch of sweetness and elegance.
How to Serve Lemon Custard Cake Recipe

Garnishes
A simple dusting of powdered sugar is lovely, but fresh garnishes can elevate this cake to a showstopper. Try scattering fresh raspberries, blueberries, or thin lemon slices over the top for a splash of color and extra tartness. A dollop of lightly whipped cream also adds an indulgent finish that complements the tangy custard beautifully.
Side Dishes
This cake pairs wonderfully with a cup of tea or a light dessert wine like Moscato. A crisp green salad with citrus vinaigrette or a fresh fruit platter makes a refreshing accompaniment that balances the richness of this luscious Lemon Custard Cake Recipe.
Creative Ways to Present
For a charming presentation, serve individual square slices on pretty dessert plates with a drizzle of honey or lemon syrup. You can also arrange slices on a cake stand garnished with edible flowers or a few sprigs of fresh mint for a lovely touch that’s perfect for brunches or special gatherings.
Make Ahead and Storage
Storing Leftovers
Storing your Lemon Custard Cake Recipe properly will keep it tasting fresh and delightful for up to 3 days. Keep it covered tightly with plastic wrap or in an airtight container, and store it in the refrigerator. This prevents the custard from drying out and preserves its creamy texture.
Freezing
While freezing is possible, it’s best to freeze individual slices wrapped tightly in plastic wrap and then placed in a freezer-safe bag. Frozen cake can last up to a month, but keep in mind that the custard’s texture might change slightly after thawing, becoming a bit less creamy.
Reheating
Since this cake is delicious served chilled or at room temperature, reheating is generally unnecessary. However, if you prefer it warm, let slices sit at room temperature for 30 minutes beforehand or gently warm briefly in a low oven just until slightly heated, being careful not to overheat and separate the custard.
FAQs
Can I use bottled lemon juice instead of fresh lemon juice?
Fresh lemon juice is highly recommended for this Lemon Custard Cake Recipe because it offers bright, natural acidity and vibrant flavor that bottled juices often lack. However, in a pinch, bottled juice can work—just be mindful that the flavor may not be as fresh and lively.
Why do the egg whites need to be whipped to soft peaks?
Whipping the egg whites to soft peaks creates the lift and airiness needed to form the delicate sponge layer on top of the custard. It adds lightness and helps the cake separate into those beautiful distinct layers during baking.
Can I make this cake dairy-free?
To make a dairy-free version, substitute the butter with a plant-based margarine and use a non-dairy milk like almond or oat milk. Keep in mind that the texture and flavor may vary slightly, but it should still yield a delicious lemon custard cake.
Why does this cake naturally separate into two layers?
The unique combination and baking method cause the denser custard mixture to settle at the bottom while the whipped egg whites rise and form a light sponge on top. This natural separation is the magic of this Lemon Custard Cake Recipe and what makes it so special.
How long does this cake keep once baked?
Stored properly in the refrigerator, this cake will keep for about 3 days. It’s best enjoyed within that window to appreciate the fresh, creamy custard and tender sponge at their peak.

This Lemon Custard Cake Recipe is one of those rare desserts that feels both nostalgic and sophisticated, all while being surprisingly easy to pull off.
