• Unsalted Butter – Provides richness; use cold and cubed for the best texture, or coconut oil for a dairy-free option.
• Egg Yolks – Create richness and aid in setting the custard; use flaxseed meal mixed with water for a vegan alternative.

Step‑by‑Step Instructions for Italian Grandma’s Lemon Custard Cake
Step 1: Make the Crust
In a mixing bowl, combine all-purpose flour, granulated sugar, and salt, blending well. Cut in cold, cubed unsalted butter with a pastry cutter or your fingers until the mixture resembles coarse crumbs. Mix in an egg yolk and just enough cold water to form a dough. Shape it into a disc, wrap it in plastic wrap, and chill in the refrigerator for 20–30 minutes for a flaky crust.
Step 2: Pre-Bake the Crust
Preheat your oven to 350°F (175°C). Remove the chilled dough from the refrigerator and roll it out on a lightly floured surface to fit your tart pan. Transfer the dough into the pan and prick the bottom with a fork to prevent bubbling. Bake the crust for 12–15 minutes until it’s lightly golden and set. Let it cool slightly while you prepare the luscious lemon custard.
Step 3: Prepare the Lemon Custard
In a medium saucepan, whisk together granulated sugar, cornstarch, and lemon zest. Gradually add in the egg yolks and whole milk while continuously stirring. Cook the mixture over medium heat, stirring until it thickens enough to coat the back of a spoon, about 5–7 minutes. Remove from heat and stir in fresh lemon juice, unsalted butter, and vanilla extract, mixing until smooth and creamy.
Step 4: Bake the Cake
Pour the silky lemon custard into the pre-baked crust, spreading it evenly with a spatula. Place it back in the oven and bake for another 25–30 minutes, until the custard is set but still slightly jiggly in the center. This gives the Italian Grandma’s Lemon Custard Cake its delightful texture, so keep an eye on it.
Step 5: Cool and Serve
After baking, remove your cake from the oven and let it cool completely at room temperature. Once cooled, refrigerate the cake for at least 4 hours or overnight to help it set beautifully. Before serving, dust the top with powdered sugar for that classic finishing touch, and enjoy the delightful flavors of this Italian Grandma’s Lemon Custard Cake!

Italian Grandma’s Lemon Custard Cake Recipe FAQs
What kind of lemons should I use for the best flavor?
Absolutely! Always opt for fresh lemons when making your Italian Grandma’s Lemon Custard Cake. Freshly squeezed lemon juice and freshly grated zest extract vibrant flavors that bottled juices simply cannot replicate. Look for lemons that are bright yellow, firm, and slightly heavy for their size, indicating juiciness.
How should I store leftover Lemon Custard Cake?
To preserve its delightful texture and flavor, store any leftover Italian Grandma’s Lemon Custard Cake in the refrigerator. Cover it tightly with plastic wrap or place it in an airtight container. It can stay fresh for up to 3 days. Just be sure to let it chill completely first before covering to avoid condensation.
Can I freeze slices of the cake?
Very! Freezing your Italian Grandma’s Lemon Custard Cake is a great way to enjoy it later. Wrap each slice tightly in plastic wrap, then place it in a freezer-safe bag or container. You’ll want to freeze it for up to 1 month. When you’re ready to enjoy, simply thaw the slices in the refrigerator overnight.
What’s the best way to ensure my custard doesn’t have lumps?
The key to a smooth custard is to strain the mixture before pouring it into the crust. After cooking the custard over medium heat, use a fine-mesh sieve to strain it into a bowl. This removes any lumps and ensures a velvety soft texture. Just pour it into the sieve and gently press with a spatula or spoon; it’s as easy as that!
Can I make this dessert vegan or gluten-free?
Absolutely! For a vegan version, substitute egg yolks with a mixture of flaxseed meal and water (1 tablespoon of flaxseed meal mixed with 3 tablespoons water for each egg). Use a non-dairy milk like almond or coconut, and replace the butter with a vegan alternative. For gluten-free, swap the all-purpose flour with a gluten-free blend. The flavors will still shine through, making it a delicious treat for everyone!
How long should I let the cake chill before serving?
It’s essential to let your cake cool completely at room temperature, then refrigerate it for at least 4 hours—overnight is even better! This chilling time allows the flavors to meld beautifully and the custard to set properly, enhancing the overall taste and texture of your Italian Grandma’s Lemon Custard Cake.
