Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat and Prepare
Preheat your oven to 325°F (163°C). While it warms, grease an 8-inch square baking dish with butter and line it with parchment paper for easy removal. Make sure the parchment overlaps the edges so you can lift the cake out later. This preparation helps ensure that your Lemon Custard Cake bakes evenly and comes out flawlessly.
Step 2: Beat Egg Yolks and Sugar
In a large mixing bowl, whisk together the four separated egg yolks and granulated sugar until the mixture turns light and creamy, taking about 3-5 minutes. The color change indicates that you’re incorporating air for a fluffy texture. Next, gently mix in the melted and cooled unsalted butter, followed by the fragrant lemon zest and freshly squeezed lemon juice, combining each ingredient thoroughly.
Step 3: Combine Dry Ingredients
Sift the all-purpose flour and salt directly into the egg yolk mixture. Stir gently until everything is just combined, being careful not to over-mix. Gradually whisk in the room temperature whole milk until the batter is smooth and has a lovely, pourable consistency. This will form a creamy, luscious base for your Lemon Custard Cake.
Step 4: Whip Egg Whites
In a separate clean bowl, beat the egg whites using an electric mixer until stiff peaks form—around 3-5 minutes. This step is crucial for the cake’s airy texture, so ensure the peaks stand tall without drooping. Once whipped, carefully fold the egg whites into the lemon batter in three additions, using a gentle motion to maintain the airiness of the mix.
Step 5: Bake the Cake
Pour the airy batter into the prepared baking dish, smoothing the top. Place it in the preheated oven and bake for 40-45 minutes. Your Lemon Custard Cake is done when the top is golden brown and the center is just set; a gentle shake should reveal a slight wobble, indicating the custard-like layer below is perfectly cooked.
Step 6: Cool and Serve
After baking, remove the dish from the oven and let the Lemon Custard Cake cool completely in the pan, about 1 hour. Once cooled, carefully lift the cake out using the parchment paper and dust the top with powdered sugar for a delightful finish. Slice it up, and enjoy the light, zesty bliss that this cake offers!

Expert Tips for Lemon Custard Cake

- Separate Eggs Properly: Ensure yolks and whites are thoroughly separated to achieve the desired airy texture. A clean bowl for egg whites prevents unwanted moisture.
- Gentle Folding: When incorporating egg whites into the batter, use a gentle folding motion to keep the mixture light and airy—over-mixing can deflate it.
- Oven Thermometer: If you’re unsure about your oven temperature, consider using an oven thermometer. Baking at the right temperature is crucial for a perfectly set custard layer.

Lemon Custard Cake Recipe FAQs
What kind of lemons should I use for the best flavor?
Absolutely! For the brightest flavor in your Lemon Custard Cake, I recommend using fresh, ripe lemons. Look for lemons that are firm and smooth-skinned, with a vibrant yellow color. Avoid any with dark spots or softer areas, as these can indicate overripeness or spoilage.
How do I store leftovers, and how long can they last?
You can store any leftover Lemon Custard Cake covered in the refrigerator for up to 3 days. Make sure it’s in an airtight container to maintain its delightful texture and flavor. The cooling process can actually enhance the taste, so it may taste even better the next day!
Can I freeze Lemon Custard Cake?
Freezing is not recommended for Lemon Custard Cake due to the delicate custard layer that may be affected. If you want to make it ahead of time, I suggest preparing it a day in advance and keeping it in the fridge. This way, you preserve its lovely texture and zesty notes.
What if my egg whites aren’t whipping to stiff peaks?
If you find that your egg whites aren’t forming stiff peaks, check that your mixing bowl and beaters are completely clean and free from any grease or moisture. Whipping them at room temperature helps, too. Just about 3-5 minutes with an electric mixer should do the trick, but if they’re still not fluffing up, try re-starting with fresh eggs and make sure the whites remain free of yolk.
Are there any allergy considerations I should keep in mind?
Definitely! If you’re concerned about allergies, be aware that this recipe contains eggs and dairy. For a dairy-free option, you can substitute whole milk with a non-dairy alternative such as almond or coconut milk. If anyone has egg allergies, unfortunately, there isn’t a straightforward substitute for eggs in this particular recipe, as they provide essential structure and aeration.
