How to Make Italian Grandma’s Lemon Custard Cake
-
Prepare the Crust: In a mixing bowl, combine the flour, sugar, and salt. Cut in the cold, cubed butter until you achieve a crumbly texture. Add the egg yolk and gradually mix in the cold water until a dough forms. Press it into a tart or square cake pan and chill for 20-30 minutes.
-
Bake the Crust: Preheat your oven to 350°F (175°C). Prick the base of the chilled crust with a fork and bake for 12-15 minutes, or until it turns lightly golden. Once done, set it aside to cool slightly.
-
Make the Custard Filling: In a saucepan, whisk together the sugar, cornstarch, lemon zest, and egg yolks. Gradually pour in the whole milk while continuously whisking. Cook over medium heat until thickened and bubbling. Remove from the heat, then mix in the lemon juice, butter, and vanilla extract.
-
Combine and Bake: Pour the luscious custard into the pre-baked crust. Bake for 25-30 minutes until the filling is just set but still slightly jiggly in the center. Allow the tart to cool completely before slicing, so the custard firms up nicely.
Optional: Garnish with a sprinkle of powdered sugar or fresh berries for a delightful touch.

Storage Tips for Italian Grandma’s Lemon Custard Cake
Room Temperature: Allow the tart to cool completely before placing it at room temperature if serving the same day. It’s best enjoyed fresh but can sit out for a few hours.
Fridge: Store leftover Italian Grandma’s Lemon Custard Cake in an airtight container in the fridge for up to 3 days. This keeps the custard creamy and fresh while preserving the tart’s delightful flavors.
Freezer: You can freeze the plain tart (without any garnishing) for up to 2 months. Cover it tightly in plastic wrap, then foil, to protect against freezer burn. Thaw overnight in the refrigerator before serving.
Reheating: If you prefer a warm slice, gently reheat in the oven at 250°F (120°C) for 10–15 minutes, ensuring it stays covered with foil to avoid browning.

Watch the Bake: Keep an eye on the custard in the oven; it should be slightly jiggly in the center, which indicates it’s perfectly set.
Cool Completely: Allow the tart to cool completely before slicing. This helps the custard firm up and leads to cleaner slices.

Italian Grandma’s Lemon Custard Cake Recipe FAQs
What should I look for when selecting lemons for the custard?
Absolutely! When choosing lemons, opt for those that are bright yellow and feel heavy for their size. The skin should be smooth and free of dark spots. Fresh lemons will yield more juice, so look for juicy ones that feel slightly soft to the touch.
How should I store the leftovers of Italian Grandma’s Lemon Custard Cake?
To store your leftover tart, simply place it in an airtight container and refrigerate for up to 3 days. This helps retain the creaminess of the custard while keeping the flavors fresh. If you’re planning to serve it later, ensure it’s cooled completely before storing to prevent moisture buildup.
Can I freeze Italian Grandma’s Lemon Custard Cake?
Yes! You can freeze the tart without garnishing for up to 2 months. Wrap it tightly in plastic wrap and then cover with foil to protect against freezer burn. When you’re ready to enjoy it, transfer it to the refrigerator to thaw overnight. Once thawed, it can be enjoyed chilled or gently reheated.
What if my custard doesn’t thicken properly?
Very! If your custard isn’t thickening, it might need more cooking time. Continue to whisk over medium heat until it bubbles and coats the back of a spoon. If it’s still too runny after cooling, it could be that the cornstarch wasn’t mixed well or the custard wasn’t cooked long enough. Always make sure you whisk continuously for a smooth texture.
Is this recipe suitable for people with egg allergies?
I often make this recipe with eggs, but if you’re catering to someone with an egg allergy, there are alternatives! You can try using a commercial egg replacer or a mixture of flaxseed meal (1 tablespoon ground flaxseed + 2.5 tablespoons water) to replace each egg yolk. Note that this might slightly alter the texture, but it can still yield delicious results.
What can I do with leftover lemon zests?
You can definitely make the most of any leftover lemon zest! It’s perfect for adding brightness to other baked goods like muffins or pancakes. You can also make lemon sugar by mixing it with sugar; this will add delightful flavor to your tea or other desserts. The more zest, the zestier your treats will be!
