Italian Grandma’s Lemon Custard Cake Ingredients
For the Crust
- All-purpose flour – Provides structure for the shortcrust base; substitute with gluten-free flour for a gluten-free option.
- Granulated sugar – Adds sweetness to both the crust and custard; consider using coconut sugar for a healthier alternative.
- Salt – Enhances flavor and balances the sweetness.
- Unsalted butter – Creates a rich, flaky crust; replace with coconut oil or margarine for a dairy-free version.
- Egg yolk – Acts as a binding agent for the crust; use ground flaxseed mixed with water for an egg-free substitute.
- Cold water – Helps bring the crust dough together.
For the Custard
- Whole milk – Forms the base of the custard, lending creaminess; substitute with almond or oat milk for a dairy-free option.
- Cornstarch – Thickens the custard and provides a smooth texture; flour can also work if cornstarch is unavailable.
- Lemon zest – Infuses the custard with intense lemon flavor; always use fresh lemons for the best results.
- Fresh lemon juice – Adds vibrancy and tang to the custard; bottled lemon juice can work in a pinch, but fresh is preferred.

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, mixing until well blended. Cut in the unsalted butter using a pastry blender or your fingertips until the mixture resembles coarse crumbs. Add the egg yolk and a few tablespoons of cold water, stirring until a dough forms. Press the dough into a tart or square pan evenly and chill it in the refrigerator for 20-30 minutes.
Step 2: Pre-Bake the Crust
Preheat your oven to 350°F (175°C) to prepare for baking. Take the chilled crust out of the refrigerator and prick it gently with a fork to prevent bubbling. Bake the crust for 12-15 minutes, or until it turns lightly golden around the edges. Once done, remove it from the oven and allow it to cool completely before adding the custard.
Step 3: Prepare the Lemon Custard
In a medium saucepan, whisk together granulated sugar, cornstarch, and lemon zest for the custard base. Gradually add the whole milk, whisking until smooth and combined. Place the saucepan over medium heat, stirring constantly. Cook the mixture until it thickens and starts to bubble gently, which should take about 5-7 minutes. Once thickened, remove from heat and stir in the fresh lemon juice, unsalted butter, and vanilla extract until fully incorporated.
Step 4: Bake the Cake
Carefully pour the freshly made lemon custard into the cooled pre-baked crust, spreading it evenly. Place the pan back into the oven and bake for 25-30 minutes. The custard should be set but will still have a slight jiggle in the center when done. Once baked, remove the cake from the oven and let it cool at room temperature.
Step 5: Chill the Cake
After the cake has cooled completely, refrigerate it for at least 4 hours, but preferably overnight, to fully set the custard and enhance the flavors. This step is crucial for achieving the perfect texture and ensuring the custard is deliciously creamy. Before serving, dust the top with powdered sugar for an elegant finish.
Storage Tips for Italian Grandma’s Lemon Custard Cake
- Fridge: Store leftover cake covered in the fridge for up to 3 days. The flavors continue to improve, making each slice taste even better!
- Freezer: If you need to store the cake for longer, wrap it tightly in plastic wrap and place it in an airtight container; it can be frozen for up to 2 months.
- Reheating: For best texture, thaw the frozen cake overnight in the fridge; enjoy chilled as intended, but for a warm treat, gently warm slices in the oven for about 10 minutes.
- Covering Custard: Always cover the top with plastic wrap or parchment paper to prevent any odors from affecting the perfect lemon flavor of your Italian Grandma’s Lemon Custard Cake.
Make Ahead Options
These Italian Grandma’s Lemon Custard Cakes are perfect for meal prep, saving you precious time on busy days! You can prepare the crust up to 24 hours in advance by mixing and chilling it in the refrigerator, making assembly a breeze. The custard can also be made the day before; just whisk the ingredients together, cool, and store it in an airtight container in the fridge (to prevent a skin from forming) until ready to use. When it’s time to bake, pour the custard into the pre-baked crust and bake as directed. This way, you’ll enjoy delicious, restaurant-quality results without the last-minute rush!

Expert Tips for Italian Grandma’s Lemon Custard Cake

Italian Grandma’s Lemon Custard Cake Recipe FAQs
What should I look for when selecting lemons for the custard?
Absolutely! For the best flavor, choose lemons that are firm and bright yellow with a smooth skin. Avoid any that have dark spots or are soft, as these can indicate overripeness. Freshly squeezed juice works wonders, so always go for fresh lemons whenever possible!
How long can I store the Italian Grandma’s Lemon Custard Cake, and how should I do it?
You can store leftover cake covered in the refrigerator for up to 3 days. Just make sure it’s well-wrapped to avoid any fridge odors and maintain its delightful lemon flavor. The flavors actually deepen as it sits, making each bite even more enjoyable!
Can I freeze the Italian Grandma’s Lemon Custard Cake, and how should I do it?
Yes, you can freeze this cake for up to 2 months! To do so, first, make sure it’s completely cooled. Wrap the cake tightly in plastic wrap, then place it in an airtight container or freezer bag. When you’re ready to enjoy it again, simply thaw it overnight in the refrigerator for the best texture.
What if my custard doesn’t thicken properly?
Very! If your custard doesn’t thicken, it might be due to not cooking it long enough. Make sure to stir constantly over medium heat, waiting until it begins to bubble gently. If it’s still too runny after cooking, you can mix a bit of cornstarch with cold water and stir it into the hot mixture while whisking. Cook for additional time until it thickens.
Are there any dietary considerations I should keep in mind for guests?
Yes, indeed! This recipe is naturally vegetarian, but if you have guests with dietary restrictions, you can easily make it dairy-free by substituting whole milk with almond or oat milk and using dairy-free butter. For anyone avoiding eggs, consider using ground flaxseed mixed with water as a binding agent for the crust. Always check for allergies, especially with ingredients like butter or milk substitutes.
