How to Make Italian Grandma’s Lemon Custard Cake
Preparing the Shortcrust Base
Let’s kick things off by preparing the shortcrust base. First, in a mixing bowl, combine all-purpose flour, sugar, and a pinch of salt. This blend will be the backbone of our cake. Next, cut in the cold, cubed butter with a pastry cutter or your fingers until it resembles coarse crumbs. Don’t overwork it; we’re aiming for flaky, after all! Then, add the egg yolk and a sprinkle of cold water. Mix gently until a dough forms. If it feels too dry, just add another splash of water. Once combined, shape the dough into a disk, wrap it in plastic wrap, and chill in the fridge for about 20–30 minutes. Chilling helps control the butter and yields that perfect crust texture!
Baking the Crust
Now it’s time to set the stage for baking! Preheat your oven to 350°F (175°C). Retrieve your chilled dough, and on a lightly floured surface, roll it out to fit your tart or square cake pan. Don’t stress if it cracks; just patch it up as you go. Once the crust is tidy in the pan, use a fork to prick the base—this prevents bubbling. Pop it into the oven and bake for 12–15 minutes or until it’s lightly golden. Keep an eye on it, so it doesn’t overbake! Allow it to cool slightly before adding the luscious lemon custard. The perfect crust sets the stage for that beautiful filling, trust me!
Making the Lemon Custard Filling
Now, for the star of the show: the lemon custard filling. In a saucepan, whisk together granulated sugar, cornstarch, lemon zest, and egg yolks until well blended. This combination gives the custard its creamy texture! Gradually pour in the whole milk while whisking. Don’t rush this part; it helps prevent lumps. Place the saucepan over medium heat and cook, stirring continuously, until the mixture thickens, about 5–7 minutes. Keep stirring to avoid any pesky lumps from forming. When thick enough to coat the back of a spoon, remove it from the heat. Stir in those zesty lemon juice, extra butter, and vanilla extract. You’ll find yourself enchanted by its fragrance!
Assembling and Baking the Cake
It’s assembling time! Carefully pour that rich lemon custard into your pre-baked crust, smoothing it out to ensure even coverage. It’s like a warm hug to that flaky base. Now, pop it back into the oven and bake for 25–30 minutes. You want it just set with a slight jiggle in the center—it gives the custard that mouthwatering texture. Once baked, remove from the oven and let it cool completely in the pan. This cooling process is crucial, allowing all those flavors to meld perfectly. After it’s cooled, slice it up, and voila! Your Italian Grandma’s Lemon Custard Cake is ready to impress!
Tips for Success
- Always use cold butter for a flaky crust; it’s non-negotiable!
- Let your dough chill—this prevents shrinkage while baking.
- Mix custard gently to avoid lumps; patience pays off!
- Check custard consistency by coating a spoon; it should be thick.
- Cool the cake completely for the best texture and flavor.
Equipment Needed
- Mixing bowl – Any large bowl will do for combining ingredients.

- Tart or square cake pan – An 8-inch round pan works as a great substitute.

Variations of Italian Grandma’s Lemon Custard Cake

- Lower Sugar Option: Reduce the granulated sugar in both the crust and custard—use honey or maple syrup for added sweetness and a unique taste.
- Lemon-Lavender Custard Cake: Add a teaspoon of culinary lavender to the custard for a fragrant aroma and a delightful twist on the classic flavor.

FAQs about Italian Grandma’s Lemon Custard Cake
Can I make Italian Grandma’s Lemon Custard Cake ahead of time?
Absolutely! This cake keeps well. You can prepare it a day in advance. Just store it covered in the fridge. The flavors will become even more delightful as it sits.
How do I store leftovers?
To keep your delicious custard fresh, store any leftovers in an airtight container. It can last in the fridge for up to three days. Just give it a little time to come back to room temperature before serving.
Can I freeze this cake?
Yes, you can freeze it! Wrap individual slices in plastic wrap, then place them in an airtight container. It should maintain its delightful flavor for about two months. When you’re ready to enjoy it, let it thaw in the fridge overnight.
What can I substitute for eggs in the custard?
If you need an egg-free option, try using a mixture of silken tofu blended until smooth or a commercial egg replacer. This should keep the custard creamy while respecting dietary restrictions.
Could I use bottled lemon juice instead of fresh?
While it’s tempting, I highly encourage using fresh lemon juice for the best flavor. Bottled juice can lack that zing. But if you’re in a pinch, it’s an option—just not quite as bright!
