What You’ll Need for This Lemon Custard Cake
Now, gathering ingredients for this Lemon Custard Cake is truly part of the fun. I always find that using fresh lemons for zest and juice makes all the difference when it comes to that bright citrus dessert flavor. Here’s my go-to list that keeps things easy and reliable:
- 2 cups all-purpose flour (the backbone of our lemon cake base)
- 1 ½ cups granulated sugar (for sweet balance against the tart custard filling)
- 1 teaspoon baking powder (helps achieve that light, tender crumb in the lemon cake)
- 1/2 teaspoon salt (to enhance all the flavors)
- 4 large eggs (separated – the whites for a fluffy cake, the yolks for the luscious custard filling)
- 1 cup unsalted butter (softened, to enrich the lemon cake)
- 1 cup whole milk (for smooth texture in both cake and custard)
- Zest of 3 lemons (fresh always wins for lemon drizzle and custard filling)
- 1/2 cup fresh lemon juice (it’s the heart of our lemon custard and drizzle)
- 1 teaspoon vanilla extract (a little secret that rounds off our citrus dessert nicely)

When making this Lemon Custard Cake, I usually pick up my lemons at the farmer’s market or local grocery’s organic section—they’re fresher and more fragrant, which is worth the small splurge. Here’s a Lemon Custard Cake trick I learned from my mom: zest the lemons before juicing so you get every bit of that lemony goodness. Also, to speed things up on busy days, I sometimes prep the zest and juice ahead and keep it refrigerated — saves loads of time when you’re ready to bake.
If you want to save costs, consider buying baking staples like flour and sugar in bulk, as they keep well and you’ll be making Lemon Custard Cake often once you taste this gem! Also, remember leftover milk and butter can be stored properly to keep your kitchen running smoothly for other recipes like my No-Bake Pumpkin Cheesecake Balls when the seasons change.
Let’s Make This Lemon Custard Cake Together
Alright, friend, roll up your sleeves and let’s get down to baking this beautiful Lemon Custard Cake. Don’t worry if this is your first try — I’ll be with you every step. In my kitchen, Lemon Custard Cake usually takes about an hour from start to delicious finish, but I promise it’s worth every minute.
- Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan — this set-up helps your lemon cake base rise evenly while the custard filling bakes perfectly.
- In a large bowl, sift together the flour, baking powder, and salt. Set aside. Getting this mix right helps the lemon cake maintain that soft, crumbly texture.
- In another bowl, cream the butter and sugar together until light and fluffy. This is where the magic starts: your lemon cake will get its tender texture here.
- Add egg yolks one at a time to the butter mixture, beating well after each addition. Then mix in the vanilla extract, lemon zest, and lemon juice. This blend is what samples the brightness of a citrus dessert in every bite.
- Gradually fold in the dry ingredients with the milk, alternating between the two until smooth. Your lemon cake batter is ready—smooth, thick, and fragrant.
- In a separate bowl, beat the egg whites until stiff peaks form. This step took me a few tries; getting that fluffy lift in the lemon cake is crucial.
- Gently fold the beaten whites into the lemon cake batter. Don’t overmix — this keeps your lemon cake light and airy.
- Pour half of the batter into your prepared pan. This forms the sturdy cake layer beneath the custard filling.
- For the custard filling, whisk together 3 egg yolks, 1 cup sugar, 1/4 cup lemon juice, and 1 teaspoon zest in a bowl until combined. Pour this custard filling over the cake layer.
- Top with the remaining lemon cake batter. It may look funny at first, but trust me, it bakes into that classic layered Lemon Custard Cake everyone loves.
- Bake for about 45 to 50 minutes, or until the top is golden and a toothpick inserted comes out clean. Your kitchen will smell like a dream of lemon drizzle and warm baked custard.
- Once cooled, drizzle a simple lemon glaze made with powdered sugar and fresh lemon juice over the cake for that finishing citrus dessert touch.
While the Lemon Custard Cake is cooking, I usually tidy up and think about how this citrus dessert will bring smiles to the dinner table. Baking can be such a calming part of the day if you let it.

If you love the idea of a lemon drizzle that’s not too sweet, tweaking the glaze with a hint of honey or a splash of vanilla can be a neat twist. And if you’re wondering about shortcuts, I’ve found that mixing the custard filling while the lemon cake base comes together cuts down time nicely.

Your Lemon Custard Cake Questions Answered
You know what I do when my Lemon Custard Cake acts up? I lean into the trial and error like a true home cook. Some readers ask me all the time about the trickiest parts, so here are a few answers from my kitchen and heart:
Q: Why did my custard filling not set properly in the Lemon Custard Cake?
A: Oh, I’ve been there! Often, it’s because the oven temperature was too high or too low, or the eggs weren’t beaten just right. I learned the hard way with my Lemon Custard Cake that gentle baking and proper mixing are key for that silky baked custard.
Q: Can I make this Lemon Custard Cake gluten-free?
A: Absolutely! I’ve swapped the flour with a gluten-free blend and it works fine, though the texture varies slightly. For a citrus dessert lover, this was a game-changer for family members with dietary preferences.
Q: Can I prepare the lemon drizzle ahead of time?
A: Yes! You can mix your lemon drizzle a day before and keep it in the fridge. Just bring it back to room temperature before pouring it over the cake. It’s part of my time-saving tips for busy days.
Q: How do I avoid overbaking the lemon cake layer?
A: Keep an eye on the edges and use a toothpick test after 40 minutes. Overbaking dries out the lemon cake, which defeats the comforting softness of this lemon custard combo.
Q: What’s the best way to store leftover Lemon Custard Cake?
A: I store mine in a sealed container in the fridge. It usually lasts 3 days without losing its moisture or flavor. And honestly, the custard filling and lemon cake get even more harmonious after a day.
Q: Can I use bottled lemon juice instead of fresh?
A: Fresh lemons really make a difference in brightness and aroma. I tried bottled juice once, and my Lemon Custard Cake lacked that vibrant citrus dessert sparkle. It’s worth squeezing the real deal!
Q: Any thoughts on using alternative sweeteners in the custard filling?
A: I experimented with honey and maple syrup—both add a unique depth, but a bit less tang. If you tweak for sweetness, keep tasting to maintain balance in your lemon drizzle and baked custard layers.
