Step‑by‑Step Instructions for Lemon Custard Cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms up, prepare a 9-inch square baking pan by lining it with parchment paper and lightly greasing it with cooking spray or butter. This will ensure your Lemon Custard Cake releases easily after baking, allowing you to present it beautifully.
Step 2: Whip the Egg Whites
Separate the eggs carefully, placing the egg whites in a large mixing bowl. Using an electric mixer, beat the egg whites until stiff peaks form, which should take about 3-5 minutes. When you lift the beater, the peaks should hold their shape. Set the whipped egg whites aside; they will add a light and airy texture to your Lemon Custard Cake.
Step 3: Mix the Egg Yolks and Sugar
In another mixing bowl, combine the egg yolks with granulated sugar. Use a whisk or electric mixer to beat them together until the mixture turns pale and fluffy, about 2-3 minutes. This step is crucial as it incorporates air and creates a light base for your cake.
Step 4: Add Butter and Vanilla
Melt the unsalted butter in the microwave or on the stove, then let it cool slightly before adding it to the egg yolk mixture. Also, mix in the vanilla extract at this stage. Stir everything together thoroughly until well combined, creating a rich and creamy consistency for your cake batter.
Step 5: Incorporate the Flour
Gradually add the all-purpose flour to the egg yolk mixture, stirring gently until just combined. Avoid overmixing to maintain the batter’s light texture, which is vital for achieving the distinct layers in your Lemon Custard Cake.
Step 6: Add Lemon Juice and Zest
Stir in the freshly squeezed lemon juice and lemon zest to the batter. This step infuses the cake with that bright, refreshing flavor you’re looking for in a Lemon Custard Cake. Mix until everything is combined, and the batter starts to glisten with citrus oil.
Step 7: Blend in the Milk
Pour in the milk gradually while stirring to create a smooth, pourable batter. The consistency should be creamy without being too thick—this will help ensure the beautiful layers form as the cake bakes.
Step 8: Fold in the Egg Whites
Now, gently fold the previously whipped egg whites into the batter using a spatula. Be careful to maintain the volume by allowing small lumps to remain; this aeration will help achieve the light custard layer on top. Stop mixing as soon as it’s incorporated.
Step 9: Bake the Cake
Pour the batter into the prepared baking pan, smoothing the top for even baking. Bake in your preheated oven for 40-60 minutes, or until the center is slightly jiggly but set. Keep an eye on it—this step is crucial as overbaking can affect the custard texture.
Step 10: Cool and Dust
Once baked, remove the Lemon Custard Cake from the oven and let it cool completely in the pan. This cooling process helps the layers set perfectly. Once cooled, dust the top with powdered sugar for a beautiful finish before slicing and serving.

Expert Tips for Lemon Custard Cake
Room Temperature Eggs: Use eggs at room temperature to ensure they incorporate smoothly and add maximum volume to the batter.
Avoid Overbaking: Keep a close eye on the cake; check at 35 minutes to prevent losing the creamy custard layer.
Gently Fold: When incorporating egg whites, fold them in gently to keep the light texture. Small lumps are perfectly fine!
Cool Completely: Allow the cake to cool fully in the pan for the best texture and ease of slicing before serving.
Flavor Boost: Don’t skip the lemon zest; it intensifies the flavor of your Lemon Custard Cake, giving it that irresistible zing!
How to Store and Freeze Lemon Custard Cake
Fridge: Store your Lemon Custard Cake in an airtight container in the refrigerator for up to 3 days. This helps maintain its delightful creamy texture.
Freezer: If you need to keep it longer, wrap the cake tightly in plastic wrap and then in aluminum foil before placing it in the freezer. It will stay fresh for up to 2 months, though the texture might change slightly upon thawing.
Reheating: To enjoy, thaw the cake in the refrigerator overnight and serve it chilled or at room temperature. This allows the flavors to reawaken beautifully!
Serving Suggestions: Dust the top with powdered sugar before serving to add a sweet touch, making your cake as beautiful as it is delicious.

Lemon Custard Cake Recipe FAQs
How do I choose ripe lemons for the Lemon Custard Cake?

When ready to enjoy, thaw it in the refrigerator overnight. For the best experience, serve it chilled or at room temperature.
What should I do if my cake is too dense?
If your Lemon Custard Cake turns out dense, ensure that you’ve properly whipped your egg whites to stiff peaks before folding them into the batter. Also, make sure to gently fold in the egg whites instead of mixing vigorously. This keeps the airy texture crucial for its layers!
Are there any dietary considerations I should keep in mind for this recipe?
Great question! For those with gluten intolerances, you can easily use gluten-free all-purpose flour in place of regular flour.
