You will love this cake because it is simple enough for a weekday baking project but impressive enough to serve at family gatherings or dinner parties. The combination of lemon zest and creamy custard makes every bite feel light yet satisfying. It also keeps well, so you can bake it a day ahead and still enjoy the same wonderful flavor.

Ingredients You Will Need

To make this Italian Lemon Custard Cake, gather these ingredients:

• 4 large eggs, separated
• ¾ cup granulated sugar
• ½ cup unsalted butter, melted and cooled
• ½ cup all-purpose flour
• 2 cups whole milk, lukewarm
• Zest of 2 lemons
• ½ cup fresh lemon juice
• 1 teaspoon vanilla extract
• Pinch of salt
• Powdered sugar for dusting

These ingredients come together to form a batter that transforms beautifully in the oven. The eggs and milk give the custard layer its creamy texture, while the lemon zest and juice bring brightness and freshness.

Step by Step Instructions

Step 1: Prepare the Pan and Oven

Preheat your oven to 325°F (160°C). Grease a square baking dish with butter or line it with parchment paper. This will help you remove the cake easily once it is baked.

Step 2: Separate and Beat the Eggs

Carefully separate the egg whites from the yolks. Place the whites in a clean bowl and whisk until stiff peaks form. This step helps the cake develop its light and airy texture. Set the whipped egg whites aside while you prepare the rest of the batter.

Step 3: Mix the Yolks and Sugar

In another bowl, whisk the egg yolks with the sugar until pale and creamy. The mixture should look thick and smooth. Add the melted butter and whisk again until well combined.

Step 4: Add Lemon and Flavorings

Stir in the lemon zest, lemon juice, and vanilla extract. The mixture will have a bright and fresh fragrance that sets the tone for the cake.

Step 5: Add Flour and Milk

Sift the flour into the egg yolk mixture and whisk gently. Slowly add the lukewarm milk, a little at a time, mixing until the batter looks smooth and slightly thin. This thin batter is normal and essential for creating the custard layer during baking.

Step 6: Fold in the Egg Whites

Gently fold the beaten egg whites into the batter. Do this in batches, mixing carefully so you do not deflate the air. It is fine if some small lumps of egg white remain. They will disappear during baking and help with the cake’s airy texture.

Step 7: Bake the Cake

Pour the batter into the prepared baking dish. Bake for 50–55 minutes or until the top is golden and slightly firm to the touch. The center will still jiggle a little but that is what creates the custard layer. Let the cake cool completely in the pan before slicing.

Step 8: Dust and Serve

Once cooled, dust the top with powdered sugar. Cut into squares or slices and serve with fresh berries if you like. The cake is best enjoyed slightly chilled, which enhances the custard flavor.

Variations You Can Try

• Add Berries: Fresh raspberries or blueberries can be sprinkled on top of the batter before baking for a fruity twist.
• Orange Version: Replace the lemon zest and juice with orange for a sweeter citrus flavor.
• Extra Creamy: Add a splash of heavy cream to the milk for a richer custard layer.

Tips for the Best Lemon Custard Cake

• Make sure the eggs are at room temperature before starting.
• Use fresh lemon juice, not bottled, for the brightest flavor.
• Do not overmix the egg whites when folding into the batter. Gentle mixing keeps the airy structure.
• Let the cake cool completely before slicing. This gives the custard time to set properly.

How to Store Lemon Custard Cake

You can store the cake in the refrigerator for up to three days. Place slices in an airtight container to prevent them from drying out. The cake can also be frozen for up to one month. Wrap slices in plastic wrap and place in a freezer bag. Thaw in the fridge before serving.

Pairing Suggestions

This cake pairs beautifully with a cup of tea or coffee. It also works well as a light dessert after a rich meal. If you love citrus desserts, you might also enjoy trying the Lemon Raspberry Cake, which balances tartness and sweetness in another delightful way.
