Ingredients

For the Cake:

3 large eggs
100 g (3.5 oz / ½ cup) granulated sugar
A pinch of salt
60 g (2 oz / ¼ cup) plain yogurt
Zest of 1 lemon (finely grated, yellow part only)
45 ml (3 tablespoons) fresh lemon juice
60 g (2 oz / ¼ cup) unsalted butter, melted
170 g (6 oz / 1⅓ cups) all-purpose flour
5 g (0.17 oz / 1 teaspoon) baking powder

For the Lemon Cream Swirl:

1 large egg
Remaining lemon zest from above
Reserved lemon juice (about 1-2 tablespoons)
60 g (2 oz / ¼ cup) granulated sugar
30 g (1 oz / ¼ cup) cornstarch
240 ml (8 fl oz / 1 cup) whole milk

For Decoration:

1-2 teaspoons powdered sugar (for dusting)

Instructions

Preparing the Lemon Zest and Juice

Thoroughly wash and dry one large lemon.
Using a fine grater, carefully zest the lemon, focusing only on the yellow outer layer which contains the most intense aroma. Set aside half for the cake batter and half for the cream.
Cut the lemon in half and squeeze to extract the juice. Measure out 45 ml (3 tablespoons) for the cake batter and reserve the remaining juice for the cream.

Making the Cake Batter

Preheat your oven to 180°C (350°F).
In a large mixing bowl, beat 3 eggs with 100 g sugar and a pinch of salt until pale and slightly thickened.
Stir in 60 g yogurt until well combined.
Add half of the lemon zest and 45 ml of lemon juice to the mixture.
Pour in 60 g melted butter and mix well.
Sift together 170 g flour and 5 g baking powder, then gradually fold into the wet ingredients.
Mix until smooth and homogeneous, being careful not to overmix.

Preparing the Lemon Cream

In a medium saucepan, whisk together 1 egg, the remaining lemon zest, reserved lemon juice, 60 g sugar, and 30 g cornstarch until smooth.
Slowly pour in 240 ml milk while whisking constantly to avoid lumps.
Place over medium heat and cook, stirring continuously with a whisk, making sure to constantly scrape the bottom of the pan to prevent burning.
Continue cooking and stirring until the mixture thickens to a pudding-like consistency.
Remove from heat once thickened.

Assembling and Baking

Grease a 9-inch (23 cm) round cake pan with butter.
Line the bottom with parchment paper for easy removal.
Pour half of the cake batter into the prepared pan.
Gently spoon the lemon cream over the batter in a spiral pattern, starting from the center.
Pour the remaining cake batter over the cream.
Using a knife or skewer, gently swirl through the batter to create a ripple effect without completely mixing the layers.
Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted in the center comes out clean and the top is golden brown.
Allow to cool in the pan for 10 minutes before transferring to a cooling rack.

Serving

Once completely cooled, dust the top with powdered sugar using a small sieve for an even coating.
Slice and serve at room temperature for the best melt-in-your-mouth texture.

Cooking Tips and Tricks

Perfect Lemon Zest: As noted in the traditional Naples technique, only zest the yellow part of the lemon peel, avoiding the bitter white pith. A microplane or fine grater works best for this.
Continuous Stirring: When making the lemon cream, never stop stirring. The constant motion prevents the mixture from sticking to the bottom and burning, ensuring a smooth, lump-free custard.
Room Temperature Ingredients: For the best texture, bring eggs, yogurt, and milk to room temperature before beginning. This creates a smoother batter that rises more evenly.
Testing Doneness: The cake is ready when it’s golden brown and springs back when lightly touched. A toothpick inserted into the cake portion (not the cream) should come out clean.
Perfect Swirl: For beautiful marbling, use a knife to create figure-eight patterns through the batter, being careful not to over-mix the cream and cake components.
Cooling Process: Allow the cake to cool in the pan for exactly 10 minutes before removing. This gives it time to set but prevents it from becoming damp from condensation.

Variations and Substitutions

Alternative Citrus Options:

Replace lemon with orange for a sweeter flavor profile
Try Meyer lemons when in season for a more floral, less acidic taste
Combine lemon with lime zest for an extra tangy variation

Dairy Substitutions:

Greek yogurt can replace plain yogurt for a richer texture
Plant-based yogurt works well for a dairy-free cake base
Almond or coconut milk can substitute for dairy milk in the cream (though the texture may be slightly different)

Flour Alternatives:

For a gluten-free version, substitute a 1:1 gluten-free flour blend
Replace up to 50g of all-purpose flour with almond flour for added moisture and flavor

Additional Flavor Enhancements:

Add 1 teaspoon of vanilla extract to the cake batter
Incorporate 2 tablespoons of poppy seeds for texture and visual appeal
For a limoncello-inspired cake, add 1 tablespoon of limoncello liqueur to the batter

Common FAQs

Q: Why did my lemon cream develop lumps?

A: Lumps typically form when eggs cook too quickly or the mixture isn’t stirred constantly. To fix this, remove from heat immediately and whisk vigorously. For prevention, consider tempering the egg by adding a small amount of warm milk first, then gradually incorporating the egg mixture back into the warm milk.

Q: Can I make this cake ahead of time?

A: Yes! This cake actually develops more flavor when made a day ahead. Store it covered at room temperature for up to 24 hours or refrigerated for up to 3 days. Bring to room temperature before serving.

Q: My cake didn’t rise as expected. What went wrong?

A: Check if your baking powder was fresh—it loses potency over time. Also, overmixing the batter can develop too much gluten, preventing proper rising. Mix just until ingredients are combined for best results.

Q: Can I freeze this lemon cake?

A: While freezing is possible, the texture of the cream swirl may change slightly upon thawing. If freezing, wrap tightly in plastic wrap and then aluminum foil for up to 1 month. Thaw overnight in the refrigerator and bring to room temperature before serving.

Q: What’s the best pan to use for this recipe?

A: A 9-inch (23 cm) round cake pan with at least 2-inch (5 cm) sides works best. Springform pans are excellent for easy removal, but ensure it’s properly sealed to prevent leakage.

Storage and Make-Ahead Tips

Short-term Storage: Store the cooled cake covered at room temperature for up to 2 days. The flavor actually improves after the first day as the lemon notes mellow and blend.

Refrigeration: For longer storage, refrigerate the cake in an airtight container for up to 5 days. Let it come to room temperature for about 30 minutes before serving to restore the melt-in-your-mouth texture.

Freezing Instructions:

Allow the cake to cool completely
Wrap individual slices or the whole cake tightly in plastic wrap
Place in an airtight container or freezer bag
Freeze for up to 1 month
Thaw overnight in the refrigerator
Bring to room temperature and dust with fresh powdered sugar before serving

Make-Ahead Components: The lemon cream can be made up to 24 hours in advance and stored covered in the refrigerator. Gently warm and stir before using to restore the proper consistency.
