Ingredients You’ll Need

Despite its restaurant-worthy results, Lemon Custard Cake comes together with a handful of everyday staples. Each ingredient plays a starring role in achieving that signature luscious texture and sunny flavor, so don’t skip any of them!

• Eggs (room temperature, separated): These form the base of the structure, with beaten whites giving lift and yolks enriching the custard layer.
• Sugar: Adds sweetness and helps give the cake that irresistible caramelized top.
• Unsalted butter (melted and slightly cooled): Lends richness and moisture to every bite.
• Vanilla extract: Enhances flavor depth and balances the citrus for a warm finish.
• All-purpose flour: Just enough to give the cake structure, while letting the custard shine.
• Freshly squeezed lemon juice: Provides tartness and that signature lemon zing—don’t use bottled!
• Grated zest from large lemons: Infuses the batter with fragrant citrus oils for a bold aroma and flavor.
• Milk (lukewarm): Helps create the magic by keeping the custard light and creamy—avoid using cold milk for best results.
• Powdered sugar (for dusting): Adds a delicate, pretty finish and a subtle sweetness on top.

How to Make Lemon Custard Cake

Step 1: Prep the Baking Dish

Start by preheating your oven to 325°F. Line an 8×8-inch baking dish with parchment paper, making sure the sides hang over for easy lifting later. Give it a light mist of cooking spray—this keeps your Lemon Custard Cake from sticking and ensures perfect slices every time.

Step 2: Whip the Egg Whites

Separate the eggs, placing the whites in a clean bowl. Whip them until stiff peaks form. The fluffy whites are key for creating the airy top layer, so be patient and whip until they’re glossy and firm. Set aside—it’s time for the yolks.

Step 3: Mix the Yolks and Sugar

In a separate bowl, vigorously beat the yolks with sugar until the mixture turns pale yellow and creamy. This step is all about aerating the yolks, setting the foundation for a lighter custard.

Step 4: Add Butter and Vanilla

Pour in the melted, cooled butter and vanilla extract. Mix until the batter looks smooth and everything is evenly combined, which boosts the silkiness of your Lemon Custard Cake.

Step 5: Add Flour

Sprinkle in the flour, mixing until just incorporated. Don’t over-mix—this helps keep the texture tender, not tough.

Step 6: Add Lemon Juice and Zest

Next, stir in the fresh lemon juice and grated zest. The juice brings tang, while the zest floods the batter with heady lemon aroma. The whole kitchen will start to smell amazing.

Step 7: Gently Mix in Milk

Pour the lukewarm milk into the bowl, incorporating it slowly to keep the batter smooth and prevent lumps. The batter will now look very thin—don’t panic! This is the magic step that transforms into layers.

Step 8: Combine with Egg Whites

Add those stiff egg whites, but don’t fold them all the way in. Leave small lumps—these will float during baking to form the fluffy top, giving Lemon Custard Cake its signature layers. The batter will be runny; that’s exactly what you want.

Step 9: Bake

Pour the batter into your prepared pan and transfer to the oven. Bake for 40 to 60 minutes. The baking time varies by oven, so start checking after 35 minutes. You want the center just barely jiggly, and the top firm to the touch. If the top browns too quickly, loosely cover with foil. Take care not to overbake, or you’ll lose the custardy middle.

Step 10: Cool and Serve

Let the cake cool completely in the pan. Once set, lift it out using the parchment paper, dust generously with powdered sugar, and admire that beautiful surface before slicing. Your Lemon Custard Cake is now ready to dazzle!

How to Serve Lemon Custard Cake

Garnishes

Dust the top of your Lemon Custard Cake generously with powdered sugar right before serving—it gives a cloudlike, pillowy finish. For an extra pop of color (and a hint to your guests about the zesty contents!), scatter on a few curls of fresh lemon zest, or top with paper-thin lemon slices. If you’re feeling decadent, a few fresh berries on the side add a burst of color and freshness.

Side Dishes

Lemon Custard Cake is a standout all on its own, but it pairs delightfully with lightly sweetened whipped cream or a scoop of vanilla ice cream. For a simple brunch, serve it with fresh fruit salad or a tangy raspberry coulis—the flavors mingle beautifully and brighten every bite.

Creative Ways to Present

This cake is as versatile as it is delicious! Cut it into squares for a dessert bar at parties, or slice into rectangles and serve on decorative plates with edible flowers for a special occasion. You can even stack cubes with whipped cream and lemon zest for a playful, layered parfait—lemony dessert dreams brought to life.

Make Ahead and Storage

Storing Leftovers

To keep your Lemon Custard Cake moist and fresh, cover it tightly with plastic wrap or transfer slices to an airtight container. Store in the refrigerator for up to three days. The fridge also helps the layers set, intensifying the custard’s creamy texture.

Freezing

Yes, you can freeze Lemon Custard Cake! Cut into individual portions, wrap each piece securely in plastic wrap, then in foil. Place in a freezer-safe bag or container. When you crave a slice, just transfer to the fridge overnight to thaw gently. The texture may be slightly softer, but the flavor stays bright and delicious.

Reheating

If you prefer your Lemon Custard Cake a bit warm, pop a slice in the microwave for 10 to 15 seconds. Avoid overheating or the custard can become rubbery. For freezer-thawed slices, let them come to room temperature first before warming.

FAQs

Can I make Lemon Custard Cake with other citrus fruits?

How do I know when the Lemon Custard Cake is perfectly baked?

The top should be firm to the touch, while the center stays just a little jiggly. Ovens can vary, so start checking at 35 minutes. Resist overbaking for the creamiest result.

Can I double the recipe for a crowd?

Definitely! Double all the ingredients and bake in a 9×13-inch pan. The texture and magic layers still come through—just keep an eye on baking time, as it may need a bit longer.

Is it possible to make Lemon Custard Cake gluten free?

Yes! Substitute your favorite gluten free all-purpose flour blend for a totally gluten free treat. The custardy layers are very forgiving, so it works surprisingly well.
