Ingredients You’ll Need
What’s wonderful about this recipe is how straightforward the ingredients are, yet each one plays an essential role in creating the perfect balance of texture, sweetness, and that irresistible lemony zing. From the cold unsalted butter that ensures a flaky crust to the fresh lemon juice bursting with brightness, every element has its own special part to play.
- 1½ cups all-purpose flour: The foundation of the crust, providing structure while keeping it tender.
- ¼ cup granulated sugar: Just a touch to sweeten the crust without overpowering it.
- Pinch of salt: Enhances flavor and balances the sweetness perfectly.
- ½ cup unsalted butter, cold and cubed: Creates that flaky, melt-in-your-mouth crust texture.
- 1 egg yolk: Binds the crust together, adding richness.
- 2–3 tbsp cold water: Helps the dough come together without becoming sticky.
- 1½ cups whole milk: Adds creaminess to the custard and helps it set beautifully.
- ¾ cup granulated sugar: Sweetens the custard while balancing the lemon’s tartness.
- 3 large egg yolks: Essential for that silky, luscious texture in the custard.
- ¼ cup cornstarch: Thickens the custard to the perfect consistency.
- Zest of 1 lemon: Infuses fragrant citrus oils for intense lemon flavor.
- ½ cup fresh lemon juice (about 2 lemons): Provides fresh, tangy brightness that defines the custard’s character.
- 2 tbsp unsalted butter: Adds smoothness and a glossy finish to the custard.
- 1 tsp vanilla extract: Gives subtle warmth and depth to the lemon custard.
How to Make Italian Grandma’s Lemon Custard Cake – Classic Recipe
Step 1: Make the Crust
Start by combining the flour, sugar, and a pinch of salt in a mixing bowl. The salt is crucial even in sweet recipes as it highlights all the flavors. Cut in the cold, cubed butter with your fingers or a pastry cutter until the mixture looks crumbly and sandy — this creates those flaky layers that will make your crust irresistible. Next, stir in the egg yolk and 2 to 3 tablespoons of cold water to bring the dough together gently. Press the dough evenly into your tart or square cake pan, then pop it into the fridge for at least 20 minutes to firm up. Chilling makes it easier to handle and helps prevent shrinking during baking.
Step 2: Pre-Bake the Crust
Preheat your oven to 350°F (175°C). Once chilled, prick the crust’s base lightly with a fork to prevent bubbling as it bakes. Bake the crust for about 12 to 15 minutes until it looks lightly golden and fragrant. This “blind bake” step ensures your crust will stay crisp even after adding the custard. Let your crust cool slightly before moving on to the custard layer so it doesn’t become soggy.
Step 3: Prepare the Lemon Custard
Here comes the heart of the cake — the lemon custard. In a saucepan, whisk together the sugar, cornstarch, lemon zest, and egg yolks until smooth and slightly pale in color. Slowly pour in the whole milk while whisking constantly to ensure no lumps form. Place the pan over medium heat and cook the mixture, stirring frequently, until it thickens enough to coat the back of a spoon. The custard should be lush and velvety, not too stiff. Remove from heat and immediately stir in the fresh lemon juice, butter, and vanilla extract. This step balances the creamy texture with the fresh tanginess that makes Italian Grandma’s Lemon Custard Cake – Classic Recipe so unforgettable.
Step 4: Bake the Cake
Pour your beautiful lemon custard carefully over the pre-baked crust, spreading it evenly. Place the whole cake back into the oven and bake for about 25 to 30 minutes. You’re aiming for the custard to be just set but still have a slight jiggle in the center—this keeps it silky and tender rather than rubbery. Once baked, remove the cake from the oven and let it cool completely, allowing the custard to fully firm up for that perfect slice every time.
How to Serve Italian Grandma’s Lemon Custard Cake – Classic Recipe
Garnishes
Simple garnishes can enhance the charm and taste of this classic cake. A dusting of powdered sugar over the top adds a delicate sweetness and a pretty finish. Fresh lemon slices or thinly peeled lemon twists echo the vibrant lemon flavor inside and add an elegant touch. For a pops of color and texture, you might also sprinkle fresh raspberries or a few mint leaves on top — they pair beautifully with the zesty custard and lift the cake’s mood from everyday to special occasion.
Side Dishes
While Italian Grandma’s Lemon Custard Cake – Classic Recipe stands beautifully on its own, it also pairs wonderfully with light accompaniments. A scoop of vanilla gelato or a dollop of freshly whipped cream balances the tart lemon custard perfectly. You can also serve it alongside a refreshing berry compote or a simple mixed greens salad with a splash of balsamic for a surprising, palate-cleansing contrast when serving after a rich meal.
Creative Ways to Present
Presentation is half the fun, and this cake is a fantastic canvas. Serve individual slices on colorful plates with a small sprig of fresh thyme or edible flowers to impress your guests. If you prefer a rustic style, dust the top generously with lemon zest and coarse sugar before baking for a textured, sparkling crust. For a twist, try layering the custard cake with fresh berries or folding in finely chopped pistachios into the crust for a nutty crunch that brings an unexpected layer of flavor.
Make Ahead and Storage
Storing Leftovers
Leftover Italian Grandma’s Lemon Custard Cake – Classic Recipe can be stored covered in the refrigerator for up to three days. Keep it in an airtight container or cover the cake tightly with plastic wrap to prevent it from absorbing any fridge odors. This way, each slice maintains its custardy smoothness and the crust stays tender but firm.
Freezing
Freezing this cake is possible but requires a bit of care. Wrap the cooled cake tightly in plastic wrap, then foil to protect it from freezer burn, and freeze for up to one month. When ready to enjoy, thaw it gently in the refrigerator overnight. Note that freezing can sometimes affect the texture of delicate custards, so it’s best eaten fresh if you can resist!
Reheating
This delicate cake is best enjoyed chilled or at room temperature, so reheating isn’t usually recommended. However, if you prefer it slightly warm, place individual slices in a low oven (around 300°F or 150°C) for 5–7 minutes—just enough to take the chill off without melting the custard or drying out the crust.
FAQs
Can I use lemon extract instead of fresh lemon juice?
While lemon extract adds flavor, fresh lemon juice provides a bright acidity and freshness essential to the custard’s vibrant taste. For the best results in Italian Grandma’s Lemon Custard Cake – Classic Recipe, fresh juice is highly recommended.
What if I don’t have cornstarch? Can I substitute it?
You can substitute cornstarch with an equal amount of all-purpose flour, but keep in mind it might slightly alter the custard’s texture, making it less smooth and glossy. Cornstarch is prized for creating that silky finish in the lemon custard.
Why is it important to pre-bake the crust?
Pre-baking, or blind baking, ensures the crust is cooked through and crisp before adding the wet custard filling. Without this step, the crust could become soggy once baked with the lemon custard, which would take away from the cake’s delightful texture.
Can I make this cake gluten-free?
You can try substituting the all-purpose flour with a gluten-free baking flour blend, but results may vary. It’s vital to use a blend designed for baking and to follow its instructions closely to maintain the right crumb and texture in the crust.
How do I know when the custard is perfectly set?
The custard should still have a slight jiggle in the center when you take the cake out of the oven, similar to a creme brulee before it sets completely. It will firm up as it cools, giving you a silky and creamy texture without being too dense or rubbery.
Final Thoughts
There’s something undeniably heartwarming about making and sharing Italian Grandma’s Lemon Custard Cake – Classic Recipe. It’s a celebration of simple ingredients, time-honored techniques, and that perfect burst of citrusy joy that only a homemade lemon custard can deliver.

Ingredients
For the Crust
- 1½ cups all-purpose flour
- ¼ cup granulated sugar
- Pinch of salt
- ½ cup unsalted butter, cold and cubed
- 1 egg yolk
- 2–3 tbsp cold water
For the Lemon Custard
- 1½ cups whole milk
- ¾ cup granulated sugar
- 3 large egg yolks
- ¼ cup cornstarch
- Zest of 1 lemon
- ½ cup fresh lemon juice (about 2 lemons)
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
Instructions
- Make the Crust: In a large bowl, combine the flour, sugar, and a pinch of salt. Cut the cold, cubed butter into the flour mixture using a pastry cutter or your fingers until the mixture resembles coarse crumbs. Add the egg yolk and cold water gradually, mixing until the dough comes together. Press the dough evenly into a tart or square cake pan. Refrigerate for 20 to 30 minutes to firm up the crust.
- Pre-Bake the Crust: Preheat your oven to 350°F (175°C). Remove the chilled dough from the fridge and prick the base with a fork to prevent rising. Bake for 12 to 15 minutes or until the crust is lightly golden. Allow it to cool slightly before adding the custard.
- Prepare the Lemon Custard: In a medium saucepan, whisk together the sugar, cornstarch, lemon zest, and egg yolks until smooth. Gradually pour in the whole milk while continuously whisking to avoid lumps. Place the pan over medium heat and cook, stirring frequently, until the mixture thickens to a pudding-like consistency. Remove from heat and stir in the fresh lemon juice, butter, and vanilla extract until fully incorporated and smooth.
- Bake the Cake: Pour the prepared lemon custard into the pre-baked crust, spreading it evenly. Bake in the preheated oven for 25 to 30 minutes, or until the custard is just set but still slightly jiggly in the center. Remove from the oven and allow to cool completely at room temperature before slicing and serving.
Notes
