How to Make Italian Grandma’s Lemon Custard Cake – Classic Recipe

Step 1: Make the Shortcrust Dough

Begin by whisking together your flour, sugar, and salt in a mixing bowl. Cut in the cold, cubed butter using a pastry cutter or your fingertips, working quickly until the mixture looks like coarse breadcrumbs. Add the egg yolk, then dribble in the cold water, stirring until a soft dough starts to form—just enough so it holds together. Press the dough into your tart or cake pan, covering the bottom and pushing gently up the sides. Cover and chill in the fridge for 20–30 minutes to rest the dough and give you that irresistible flakiness after baking.

Step 2: Pre-Bake the Crust

Preheat your oven to 350°F (175°C). Remove the chilled dough from the fridge and gently prick it all over with a fork. This little trick helps prevent bubbles during baking. Slide the pan into the oven and bake for 12–15 minutes until the edges are just turning golden and the base looks dry but not too dark. Allow the crust to cool while you prepare the silky lemon custard filling.

Step 3: Prepare the Lemon Custard

In a medium saucepan, whisk together the granulated sugar, cornstarch, lemon zest, and egg yolks until smooth and pale. Slowly pour in the whole milk while whisking continuously to prevent any lumps. Cook over medium heat, stirring constantly, until the mixture thickens to a creamy, pudding-like consistency. As soon as it’s thick, take it off the heat and stir in the fresh lemon juice, unsalted butter, and vanilla extract until everything is glossy and beautifully blended. Take a moment to sample a tiny spoonful—this is lemon bliss!

Step 4: Bake the Cake

Pour the warm custard into your baked crust, evening out the top with a spatula. Carefully transfer it back to the oven and bake for another 25–30 minutes. The custard should look set at the edges but still have a gentle wobble in the center. Remove it from the oven and let it cool completely; this allows the filling to firm up enough for clean slices when you’re ready to serve.

How to Serve Italian Grandma’s Lemon Custard Cake – Classic Recipe

Garnishes

For a true Italian Grandma’s Lemon Custard Cake – Classic Recipe finish, dust the top lightly with powdered sugar right before serving, or add a scattering of finely grated lemon zest for extra pop. A few fresh berries or mint leaves can add bursts of color and a touch of elegance for special occasions.

Side Dishes

This cake shines on its own, but you can take it to the next level with a dollop of freshly whipped cream or a scoop of vanilla gelato. For a lovely contrast, pair it with a bright raspberry coulis or a handful of macerated summer berries.

Creative Ways to Present

If you’re hosting, consider slicing the Italian Grandma’s Lemon Custard Cake – Classic Recipe into dainty squares for a dessert tray or into slim wedges for a plated dessert. Individual tartlets using the same base and custard are a delightful twist for tea parties or brunch tables.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, keep your cake covered in the refrigerator. It will stay fresh and luscious for up to three days, the crust maintaining a pleasant crispness and the filling staying deliciously smooth.

Freezing

To freeze, wrap individual slices tightly in plastic wrap and slide them into a freezer bag. Thaw overnight in the fridge to enjoy a chilled treat that tastes freshly baked—ideal for making a batch ahead of a busy week or special event.

Reheating

Enjoying a warm slice? Pop it in a low oven (about 250°F) for 10–12 minutes, or simply let it come to room temperature for that creamy custard texture. Avoid microwaving, which can make the crust soggy or the custard rubbery.

FAQs

Can I use bottled lemon juice instead of fresh?

While bottled juice will work in a pinch, the flavor just won’t be the same as using fresh lemons. Fresh juice and zest are what truly bring the Italian Grandma’s Lemon Custard Cake – Classic Recipe to life with bright, aromatic notes.

Do I need a tart pan with a removable bottom?

No special equipment required—a square cake pan or any standard tart pan works well. A removable base just makes slicing and serving even easier, but isn’t essential for success.

What if my custard doesn’t thicken?

Custard needs gentle, consistent heat to set up. If it’s not thickened after several minutes, keep cooking and whisking—don’t rush, and it will come together. Be careful not to let it boil hard.

Can I make the crust and filling in advance?

Absolutely. You can prep the crust dough a day ahead and store it chilled, or even bake it off in advance. The filling is best poured and baked fresh, but the fully assembled cake keeps beautifully in the fridge.

Is this cake suitable for gluten-free or dairy-free diets?

If you need a gluten-free version, use your favorite GF flour blend with a pinch of xanthan gum. For dairy-free, substitute plant-based butter and milk—but be aware, it may change the flavor and texture a bit.
