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 heats, generously grease an 8×8-inch baking dish with butter or cooking spray. This vital step ensures your Lemon Custard Cake releases easily after baking. Set the prepared dish aside as you move on to mixing the batter.
Step 2: Cream Butter and Sugar
In a large mixing bowl, cream together ½ cup of unsalted butter and 1 cup of granulated sugar until the mixture is light and fluffy, which should take about 3-5 minutes. You’ll know it’s ready when it’s pale in color and has doubled in size. This fluffy mixture is essential for the texture of your Lemon Custard Cake.
Step 3: Incorporate Egg Yolks and Zest
Add in the egg yolks, one at a time, mixing well after each addition to ensure even incorporation. Then, stir in the zest of one lemon and ¼ cup of freshly squeezed lemon juice. The citrus flavors will create that signature taste of the Lemon Custard Cake, giving it a fresh and vibrant appeal.
Step 4: Mix Dry Ingredients
In a separate bowl, whisk together 1 cup of all-purpose flour, 2 teaspoons of baking powder, and a pinch of salt. Gradually blend this dry mixture into the wet ingredients, being careful not to overmix. The combination of these elements is crucial for achieving the ideal cake structure.
Step 5: Add Milk
Slowly pour in 1 cup of warm milk while gently mixing until the batter is smooth and thin. The warmth of the milk helps to dissolve the sugar completely and creates a luxurious base for your custard layer. The batter will seem runny at this stage, but that’s perfectly normal for the Lemon Custard Cake.
Step 6: Whip Egg Whites
In a clean bowl, beat the egg whites until they reach stiff peaks, which typically takes about 5 minutes with an electric mixer. The egg whites provide airiness to the cake layer, so ensure no yolk is present. Gently fold the whipped egg whites into the batter, taking care not to deflate them.
Step 7: Pour and Bake
Carefully pour the batter into the prepared baking dish, smoothing it out to create an even layer. Bake in the preheated oven for 35-40 minutes, or until the top is a lovely golden brown and slightly jiggly in the center. This step is crucial for allowing the custard layer to form underneath.
Step 8: Cool and Serve
Once baked, cool the Lemon Custard Cake in the dish for at least 30 minutes. After cooling, you can dust it with powdered sugar or top it with fresh berries for a delightful decoration. This cake can be served warm or chilled, creating a refreshing dessert experience perfect for any occasion.

Lemon Custard Cake Recipe FAQs
How do I select the best lemons for this recipe?
When choosing lemons for your Lemon Custard Cake, look for ones that are bright yellow, firm to the touch, and slightly heavy. A good lemon should have a fragrant aroma. Avoid lemons with dark spots or blemishes as they may indicate overripeness or spoilage. Freshness is key for that vibrant citrus flavor!
How should I store leftovers of the Lemon Custard Cake?
To keep your Lemon Custard Cake fresh, simply place it in an airtight container and refrigerate for up to 4 days. This helps maintain its delicious flavor and creamy custard texture. You can enjoy it either cold for a firmer texture or warm it in the microwave for about 10-15 seconds for a soft custard experience.
Can I freeze the Lemon Custard Cake?
Absolutely! For long-term storage, wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. This method will keep your cake tasty for up to 3 months. To thaw, simply move the wrapped slices to the refrigerator overnight. You can enjoy it cold or warm it gently in the oven for about 10 minutes at 350°F (175°C).
What should I do if my custard layer isn’t forming correctly during baking?
If your custard layer doesn’t form properly, it could be due to overmixing the batter or not folding the whipped egg whites gently enough. Be careful to combine your ingredients just until smooth and avoid deflating the egg whites, as they’re crucial for the texture. Baking the cake until it has a slight jiggle in the center is also essential for achieving that creamy custard layer beneath.
Is this Lemon Custard Cake suitable for special diets?
Yes, the Lemon Custard Cake is vegetarian-friendly, making it a delightful option for those avoiding meat. If you have allergies or dietary concerns, I recommend using dairy-free milk alternatives, like almond or oat milk, and substituting eggs with an appropriate egg replacer for a vegan version. Just keep in mind that these adjustments may alter the final flavor and texture slightly.
