• Salt (1/4 teaspoon) – Balances sweetness and enhances flavors.
• Milk (1 1/4 cups, at room temperature) – Ensures the batter has a smooth consistency; substitute almond or oat milk for a dairy-free option.

Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat the Oven
Start by preheating your oven to 325°F (160°C). While the oven warms up, take a 9×9-inch baking pan and generously grease it with unsalted butter or cooking spray. Then, line the bottom with parchment paper for easy removal later. This ensures your moist Lemon Custard Cake won’t stick, making your baking experience hassle-free.
Step 2: Mix Egg Yolks and Sugar
In a large mixing bowl, combine 4 large egg yolks with 1 1/4 cups of granulated sugar. Use a whisk to beat the mixture for about 2-3 minutes until it becomes pale and creamy. This step is crucial, as it aerates the mixture, giving your cake its signature lightness. Set the bowl aside when you achieve a smooth texture.
Step 3: Add Flavorful Ingredients
Now, it’s time to enhance the batter’s flavor. Add 1 tablespoon of freshly grated lemon zest, 1/2 cup of fresh lemon juice, 1/2 cup of melted unsalted butter, and 1 teaspoon of vanilla extract to the egg yolks. Mix everything well until you have a consistent, silky-smooth batter. The fresh lemon zest will infuse the cake with a bright and zesty aroma.
Step 4: Incorporate Dry Ingredients
Sift together 1 cup of all-purpose flour and 1/4 teaspoon of salt in a separate bowl. Gradually add this dry mixture to the wet ingredients, stirring gently until combined. Be careful not to overmix, as this could affect the texture of your Lemon Custard Cake. You want a smooth batter without lumps for a lovely finish.
Step 5: Blend in the Milk
Next, slowly whisk in 1 1/4 cups of room temperature milk, ensuring the batter achieves a thin, custard-like consistency. This step is vital for the creamy texture of your cake. The milk adds richness while balancing the flavors, making your Lemon Custard Cake irresistibly smooth. Mix until fully incorporated.
Step 6: Whip Egg Whites
In a clean bowl, beat the 4 large egg whites until stiff peaks form. This should take about 3-5 minutes with a hand mixer or stand mixer. The whipped egg whites will add height and fluffiness to your cake. Once done, gently fold the whipped egg whites into the batter, being careful to retain the airiness for a light texture.
Step 7: Prepare for Baking
Pour the prepared batter into the greased and lined 9×9-inch baking pan. Use a spatula to spread the mixture evenly and smooth the top. This ensures an even bake and a beautiful presentation for your Lemon Custard Cake. It’s essential to take your time here for the best results.
Step 8: Bake the Cake
Place the cake in the preheated oven and bake for about 40-45 minutes. You’ll know it’s ready when the top is golden brown and the center jiggles slightly but is set. Keep an eye on it toward the end of the baking time to avoid overcooking. The aroma will fill your kitchen, a true indicator of what’s to come!
Step 9: Cool Before Serving
Once baked, remove the Lemon Custard Cake from the oven and let it cool completely in the pan. This cooling time is essential as it allows the custard to set properly. Once cooled, carefully lift the cake out of the pan using the parchment paper and dust the top with powdered sugar before slicing and serving.

Lemon Custard Cake Recipe FAQs
How do I know if my lemons are ripe?
Absolutely! Ripe lemons should feel heavy for their size and have a slightly glossy skin. Look for lemons that are vibrant yellow, without green patches or dark spots all over. The scent should be fragrant—if they smell citrusy and fresh, you’ve got the right ones!
What is the best way to store Lemon Custard Cake?
Store your Lemon Custard Cake covered in the refrigerator for up to 4 days to maintain its freshness and flavor. Simply place it in an airtight container or wrap it well. Remember to let it cool completely before covering, as this helps avoid excess moisture, keeping your cake perfectly moist.
Can I freeze Lemon Custard Cake?

When you’re ready to enjoy, thaw the cake in the refrigerator overnight, and for the best texture, let it come to room temperature before serving. Dust with powdered sugar right before serving for added sweetness!
What if my Lemon Custard Cake is too dense?
If your cake turns out denser than expected, it may be due to overmixing the batter or not folding in the egg whites gently enough. Always mix just until combined, and when adding the beaten whites, use a spatula to fold in from the bottom, gently rotating to maintain airiness. This will ensure a lighter texture and improve the overall result.
Can this Lemon Custard Cake be made dairy-free?
