Ingredients

For the Cake Base:

3 large eggs
A pinch of salt
½ teaspoon vanilla sugar or vanilla extract
140g (5oz) granulated sugar
150ml (⅔ cup) milk
100ml (⅓ cup + 1 tablespoon) vegetable oil
8 heaped tablespoons all-purpose flour (approximately 200g/7oz)
1 teaspoon baking powder
Zest of 1 lemon
Juice of 1 lemon (approximately 2-3 tablespoons)

For the Lemon Cream Filling:

1 egg
70g (⅓ cup) granulated sugar
½ teaspoon vanilla sugar or vanilla extract
2 tablespoons cornstarch
300ml (1¼ cups) milk
40g (3 tablespoons) butter
Zest of 1 lemon (optional, for extra lemon flavor)

Additional:

Butter for greasing the baking dish
Powdered sugar for dusting (optional)

Instructions

Preparing the Cake Batter:

Prepare your workspace: Preheat your oven to 170°C (340°F). Thoroughly grease a 26cm (10-inch) round cake or tart pan with butter.
Mix wet ingredients: In a large mixing bowl, combine 3 eggs, a pinch of salt, ½ teaspoon vanilla sugar (or vanilla extract), and 140g sugar. Beat the mixture using an electric mixer on medium-high speed for about 5 minutes until it becomes light in color and fluffy in consistency.
Add liquids: Reduce the mixer speed to low and gradually add 150ml milk and 100ml vegetable oil. Mix until just combined.
Incorporate dry ingredients: In a separate bowl, whisk together the flour and baking powder. Add the dry ingredients to the wet mixture in two batches, mixing gently after each addition to avoid lumps. Don’t overmix – stir just until no dry streaks remain.
Add lemon flavor: Grate the zest of one lemon directly into the batter. Squeeze the juice from the same lemon and add it to the mixture. Fold gently to incorporate.
Bake the cake: Pour the batter into the prepared baking dish. Bake in the preheated oven for approximately 40 minutes, or until a toothpick inserted into the center comes out clean and the top is golden brown.

Preparing the Lemon Cream Filling:

Mix the base: While the cake is baking, prepare the lemon cream. In a medium saucepan, whisk together 1 egg, 70g sugar, ½ teaspoon vanilla sugar (or vanilla extract), and 2 tablespoons cornstarch until smooth.
Add milk: Gradually whisk in 300ml milk until the mixture is completely smooth with no lumps.
Cook the cream: Place the saucepan over low heat. Cook the mixture, stirring constantly with a wooden spoon or heat-resistant spatula, until it thickens enough to coat the back of a spoon (about 5-7 minutes). Do not allow it to boil.
Finish the cream: Once thickened, remove from heat and add 40g butter. Stir until the butter is completely melted and incorporated. If desired, add additional lemon zest for a more pronounced lemon flavor.
Cool the cream: Transfer the lemon cream to a bowl and cover the surface directly with plastic wrap (to prevent a skin from forming). Allow it to cool to room temperature.

Assembly:

Cool the cake: Once baked, remove the cake from the oven and allow it to cool in the pan for 10 minutes. Then transfer to a wire rack to cool completely.
Cut and fill: When both the cake and cream are completely cool, carefully slice the cake horizontally into two layers. Spread the lemon cream evenly over the bottom layer, then place the top layer back on.
Finish: Just before serving, dust the top of the cake with powdered sugar if desired.

Cooking Tips and Tricks

Room temperature ingredients: For the fluffiest cake texture, ensure your eggs are at room temperature before beating them with the sugar.
Proper mixing: When beating the eggs and sugar, don’t rush this step. The mixture should nearly triple in volume and become pale, which incorporates crucial air into the batter.
Lemon selection: Choose fresh, unwaxed lemons for the best flavor. Roll them firmly on the countertop before juicing to maximize the amount of juice extracted.
Zesting technique: When zesting the lemon, be careful to only take the yellow outer layer, avoiding the bitter white pith beneath.
Cream troubleshooting: If your lemon cream develops lumps, pass it through a fine-mesh sieve while still warm.
Baking check: Start checking your cake at around 35 minutes. Every oven is different, and you want to avoid overbaking, which can dry out the cake.
Cooling patience: Allow both the cake and cream to cool completely before assembly to prevent the cream from melting or making the cake soggy.

Variations and Substitutions

Citrus Variations

Replace lemon with orange for a sweeter, less tangy version
Try lime for a more intense, tropical flavor
Use Meyer lemons when in season for a sweeter, more aromatic cake
Create a mixed citrus version with a combination of lemon, lime, and orange

Dietary Adaptations

For a dairy-free version, substitute plant-based milk and vegan butter
Replace regular flour with a 1:1 gluten-free flour blend plus ½ teaspoon xanthan gum
For reduced sugar, try a monk fruit or erythritol sweetener (use 20% less by volume)
Use coconut oil instead of vegetable oil for a subtle coconut undertone

Flavor Enhancements

Add 1 tablespoon of limoncello to the cake batter for an adult version
Incorporate 1 tablespoon of poppy seeds into the batter for texture and visual appeal
Add 100g (3.5oz) of fresh blueberries to the batter for a lemon-blueberry variation
Include a teaspoon of fresh thyme leaves in the cake batter for an herbal note

Structural Variations

Bake in a loaf pan for a lemon pound cake style (adjust baking time to 50-55 minutes)
Make cupcakes instead of a large cake (bake for approximately 20-22 minutes)
Create a layered trifle by cutting the cake into cubes and layering with the lemon cream and fresh berries
Use the batter to make a bundt cake (increase baking time by about 10-15 minutes)

Common FAQs

Why did my cake sink in the middle?

This typically happens when the oven door is opened too early in the baking process or if the cake is underbaked. Avoid opening the oven door during the first 30 minutes of baking, and make sure your oven is properly preheated.

Can I make this cake a day ahead?

Absolutely! In fact, the flavors develop beautifully overnight. Assemble the cake completely, cover it loosely with plastic wrap, and refrigerate. Bring to room temperature about 30 minutes before serving.

My lemon cream isn’t thickening. What am I doing wrong?

The key is to cook it slowly over low heat while stirring constantly. If it’s not thickening, you may need to increase the heat slightly or add an additional teaspoon of cornstarch (mixed with a little cold milk first).

Can I freeze this cake?

Yes, but freeze it without the filling. Wrap the unfilled cake layers well in plastic wrap and then aluminum foil. Freeze for up to 1 month. Thaw completely before filling with freshly made lemon cream.

Why is it important to add the flour in two steps?

Adding flour gradually prevents lumps and helps maintain the air bubbles created during the egg-beating process, resulting in a lighter, fluffier cake texture.

Storage and Make-Ahead Tips

Unfilled cake: The baked cake layers can be stored at room temperature, wrapped in plastic wrap, for up to 2 days before filling.
Lemon cream: The cream can be made up to 2 days ahead and stored in an airtight container in the refrigerator with plastic wrap pressed directly onto the surface to prevent skin formation.
Assembled cake: Once filled, the cake should be refrigerated and consumed within 3 days for best quality. Allow it to sit at room temperature for about 30 minutes before serving for the best texture and flavor.
Freezing: For longer storage, individual slices can be frozen by wrapping them tightly in plastic wrap and then aluminum foil. Thaw in the refrigerator overnight.
Serving tip: For the cleanest slices, dip your knife in hot water and wipe clean between cuts.

This Italian lemon cake is sunshine on a plate – simple to make yet impressive to serve. The bright, vibrant flavors paired with the melt-in-your-mouth texture make it a standout dessert for any occasion, from casual family gatherings to elegant dinner parties. Buon appetito!
