For the Batter
• Egg Whites – Provides structure and lightness; use fresh eggs for the best results.
• Egg Yolks – Adds richness and color; essential for the custard layer.

• Unsalted Butter – Contributes to flavor and moisture; can be replaced with coconut oil for a dairy-free option.
• Fresh Lemon Zest – Enhances lemon flavor; do not substitute with bottled zest.
• Fresh Lemon Juice – Provides tartness; always use fresh juice for best flavor.
• All-Purpose Flour – Creates structure and body; can be swapped with gluten-free flour for a gluten-free version.

• Cream of Tartar – Stabilizes egg whites, aiding in achieving stiff peaks.
Step‑by‑Step Instructions for Magic Lemon Custard Cake Recipe
Step 1: Preheat and Prepare the Pan
Begin by preheating your oven to 325°F (163°C). While the oven heats, prepare an 8-inch square baking pan by generously greasing it with butter and lining the bottom with parchment paper. This will ensure your Magic Lemon Custard Cake releases smoothly after baking, making cleanup easier.
Step 2: Beat the Egg Whites
In a clean, dry mixing bowl, use an electric mixer to beat the egg whites along with the cream of tartar. Whip them on medium-high speed until stiff peaks form, which should take about 3-5 minutes. The egg whites should be glossy and hold their shape well when the beaters are lifted, contributing to the lightness of the cake.
Step 3: Whisk the Egg Yolks and Sugar
In a separate mixing bowl, whisk the egg yolks and granulated sugar together until the mixture turns pale and thick, which can take 2-3 minutes. You want to create a creamy base that will add richness to your Magic Lemon Custard Cake, so ensure that the sugar is fully incorporated and there are no grains.
Step 4: Incorporate Butter and Zest
Gradually pour in the melted unsalted butter while whisking continuously to combine with the yolk mixture. Next, add the fresh lemon zest, mixing until fully integrated. This step infuses the magic cake with refreshing lemon flavor, enhancing its tartness and aroma.
Step 5: Add Flour and Combine
Sift the all-purpose flour over the mixture, then gently fold it in using a spatula. Take care not to overmix, as you want a smooth batter. Folding ensures that the air you created with the egg whites remains intact, leading to the airy texture of the cake’s top layer.
Step 6: Mix in Lemon Juice and Milk
Stir in the fresh lemon juice and milk until the batter is smooth and uniform in consistency. This will give your cake the liquid it needs to bake properly while keeping it moist. The mixture should be slightly runny, indicating it’s ready for the next step.
Step 7: Fold in the Egg Whites
Carefully fold in one-third of the beaten egg whites into the batter to lighten it. Once mixed, gently fold in the remaining egg whites until no white streaks remain. This folding technique helps maintain the airy texture that makes the layers of the Magic Lemon Custard Cake so special.
Step 8: Bake the Cake
Pour the batter into the prepared baking pan and place it in the preheated oven. Bake for 40-50 minutes, or until the top layer is golden brown and the center jiggles slightly. It’s essential to avoid opening the oven door during baking to prevent the cake from collapsing.
Step 9: Cool and Chill
Once baked, remove the cake from the oven and let it cool completely on a wire rack, which will take about 30 minutes. Once cool, refrigerate the cake for at least 2 hours. Chilling allows the flavors to meld and the custard center to set, creating that delightful texture you’ll enjoy.
Step 10: Serve with a Dusting of Sugar
Before serving your Magic Lemon Custard Cake, dust the top lightly with powdered sugar for a lovely presentation. Slice into squares and serve chilled, optionally with a dollop of whipped cream or a scoop of vanilla ice cream for an indulgent touch.

Magic Lemon Custard Cake Recipe FAQs
How do I know if my lemons are ripe for this recipe?
Absolutely! When selecting lemons, look for those that are firm, heavy for their size, and have a vibrant yellow color. Avoid any with dark spots or wrinkled skin, as they tend to be overripe. Fresh, juicier lemons will enhance the flavor of your Magic Lemon Custard Cake immensely.
What is the best way to store leftover Magic Lemon Custard Cake?
To keep your cake fresh, wrap the cooled Magic Lemon Custard Cake tightly in plastic wrap or store it in an airtight container. It will stay delicious in the refrigerator for up to 3 days. This method helps maintain the delightful texture of the cake, ensuring every slice is just as enchanting as the first.
Can I freeze my Magic Lemon Custard Cake?

When you’re ready to enjoy it, transfer the cake to the fridge to thaw overnight, keeping its magical custard layers intact.
What should I do if my cake is too dense when baked?
If your cake turns out denser than expected, it might be due to overmixing the batter, especially when folding in the egg whites. This process should be gentle to retain the airiness. Next time, ensure that you’re folding just until no streaks remain. Additionally, using room temperature ingredients can help create a lighter texture.
Are there any dietary considerations?
Very! If you’re baking for anyone with dietary restrictions, you can easily adapt this recipe. For a gluten-free version, swap all-purpose flour for a gluten-free substitute. If someone is dairy-free, use coconut oil instead of butter and almond milk in place of whole milk. Always check for allergies when using fresh fruits or alternative sweeteners!
