For the Crust

All-Purpose Flour – Essential for creating a sturdy yet tender crust; gluten-free flour works as a substitute.
Granulated Sugar (for crust) – Adds sweetness and balance; coconut sugar can be used for a less refined option.
Salt – Enhances flavor; a pinch is necessary to balance sweetness.
Unsalted Butter – Provides richness and texture; make sure it’s cold and cubed for a flaky crust, or swap with vegan butter for a dairy-free alternative.
Egg Yolk – Acts as a binding agent for the crust; for an egg-free option, a flax egg can be used.
Cold Water – Helps in forming the dough; adjust the quantity to achieve the right consistency.

For the Custard

Whole Milk – Adds creaminess to the custard; use whole or low-fat milk, or alternative milks like almond or coconut for a dairy-free custard.
Granulated Sugar (for custard) – Contributes sweetness; adjust according to your taste.
Egg Yolks (for custard) – Provides richness and helps thicken the custard; no substitutes are recommended for this part.
Cornstarch – Serves as a thickening agent; you may use flour, but results can vary.
Lemon Zest – Infuses aromatic oils for flavor; always use fresh lemons for the best results.
Fresh Lemon Juice – The key flavor component; fresh juice is preferred for vibrancy, though bottled juice is an option in a pinch.
Unsalted Butter (for custard) – Adds extra richness; can be replaced with vegan butter if desired.
Vanilla Extract – Enhances the depth of flavor; no suitable substitute yields the same effect.

Step‑by‑Step Instructions for Italian Grandma’s Lemon Custard Cake

Step 1: Make the Crust
In a large mixing bowl, combine the all-purpose flour, granulated sugar, and salt. Cut in the cold, cubed unsalted butter using a pastry cutter until the mixture resembles coarse crumbs. Stir in the egg yolk and 2 tablespoons of cold water until a dough forms. Press this dough into a tart or cake pan, ensuring an even thickness, then chill for 20-30 minutes to firm up.

Step 2: Pre-Bake the Crust
Preheat your oven to 350°F (175°C). Once the crust has chilled, remove it from the fridge and prick the bottom with a fork to prevent bubbling. Bake for 12-15 minutes, until the crust is lightly golden and fragrant. Allow it to cool slightly on a wire rack while you prepare the luscious lemon custard.

Step 3: Prepare the Lemon Custard
In a medium saucepan, whisk together the granulated sugar, cornstarch, egg yolks, and freshly grated lemon zest until smooth. Gradually pour in the whole milk while whisking continuously to prevent lumps. Cooking over medium heat, stir frequently until the mixture thickens and coats the back of a spoon, about 5-7 minutes. Remove from heat and gently stir in the fresh lemon juice, unsalted butter, and vanilla extract until fully combined.

Step 4: Bake the Cake
Carefully pour the prepared custard into the pre-baked crust, spreading it evenly. Bake in the preheated oven for 25-30 minutes, or until the edges of the custard are set but the center remains a bit jiggly. This ensures a perfect creamy texture once cooled. Remove from the oven and allow it to cool completely on the counter.

Step 5: Chill Before Serving
Refrigerate the cake for at least 4 hours to allow the lemon custard to fully set and develop its flavors. Once chilled, dust the top of your Italian Grandma’s Lemon Custard Cake with powdered sugar for a beautiful presentation. Slice and serve with your favorite fresh berries or a dollop of whipped cream for an extra special touch.

How to Store and Freeze Italian Grandma’s Lemon Custard Cake

Fridge: Store the cake covered in the refrigerator for up to 3 days. It’s best to let it chill overnight, allowing the flavors to deepen and the custard to set perfectly.

Freezer: If you need to store it longer, wrap the cake tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 2 months. Thaw in the fridge before serving.

Reheating: If desired, you can serve the cake cold straight from the fridge, or gently warm individual slices in the microwave for about 10-15 seconds.

Serving Suggestions: For the best presentation, dust with powdered sugar just before serving to enhance the delicious look of your Italian Grandma’s Lemon Custard Cake.

Expert Tips for Italian Grandma’s Lemon Custard Cake

Fresh Ingredients Matter: Always use fresh lemons for zest and juice. The vibrant oils and flavors can elevate your Italian Grandma’s Lemon Custard Cake.
Chill the Crust: Prevent shrinkage during baking by chilling your crust. This keeps it flaky and prevents any unwanted warping.
Strain for Smoothness: For a velvety custard, strain the mixture after cooking. This step removes any lumps and results in a silky texture.
Cool Completely: Allow the cake to cool completely before refrigerating. This ensures the custard sets properly, resulting in a perfect slice.
Dust Just Before Serving: To keep the powdered sugar presentation fresh, dust your cake only when you’re ready to serve. This maintains its aesthetics and contrasts beautifully with the custard.

Make Ahead Options

The Italian Grandma’s Lemon Custard Cake is a dream come true for busy home cooks looking to save time! You can make the crust up to 24 hours in advance; simply prepare it, press it into your tart or cake pan, and refrigerate it until you’re ready to bake. The custard can also be made ahead; store it in the refrigerator for up to 3 days. When it’s time to serve, just pour the custard into the pre-baked crust, bake as directed, and allow it to set. Chilling overnight enhances the flavors, ensuring this delightful cake remains just as delicious while easing your day-of stress. Enjoy the gift of homemade flavor!

Italian Grandma’s Lemon Custard Cake Recipe FAQs

What type of lemons should I use for the recipe?
Absolutely! For the best flavor, I recommend using fresh, organic lemons. Look for ones that are firm and brightly colored, avoiding any with dark spots or wrinkles, as they won’t yield the zesty oil needed for that perfect lemon custard.

How should I store the cake once it’s made?
The cake should be stored in the refrigerator, covered, for up to 3 days. It’s best to let it chill overnight for optimal flavor, allowing the custard to set beautifully. Use a cake dome or wrap it in plastic wrap to maintain freshness and prevent absorption of other fridge odors.

Can I freeze Italian Grandma’s Lemon Custard Cake?
Yes, you can! To freeze, wrap the cake tightly in plastic wrap followed by aluminum foil to avoid freezer burn. It will keep well for up to 2 months. When you’re ready to enjoy, simply transfer it to the refrigerator to thaw overnight, or for a quicker option, let it sit at room temperature for a couple of hours.

What should I do if my custard doesn’t thicken properly?
If your custard doesn’t thicken, don’t worry—this can happen sometimes! First, ensure you’re cooking over medium heat, stirring constantly until the mixture thickens (it should coat the back of a spoon). If it’s still too runny after cooling, you can gently reheat it on the stove and add a bit more cornstarch mixed with cold milk to help it thicken further. Always strain the custard to get that silky texture.

Are there any dietary restrictions I should consider?
This cake is vegetarian-friendly, but if you’re serving guests with dietary restrictions, note that the recipe contains eggs and dairy. For dairy-free options, you can substitute the whole milk and unsalted butter with almond milk and vegan butter. Similarly, flax eggs can replace regular eggs if you’re aiming for an egg-free cake.

How can I enhance the flavors of the custard?
To elevate the bright, tangy flavor of your Italian Grandma’s Lemon Custard Cake, consider adding a teaspoon of lemon extract alongside the fresh lemon juice for an intensified lemony punch. Alternatively, a sprinkle of fresh herbs like mint can offer a surprising and refreshing contrast when serving!
