I love the way a warm slice of Authentic Italian Grandma’s Cake makes a room hush. I call this recipe Authentic Italian Grandma’s Cake because it mixes a crisp pastry with a soft lemon custard. I share it here so you can make it at home and smile at the first bite.
My Dad James loved this cake with strong black coffee. I remember him cutting the first piece and nodding like he always did when a dish felt like home.

I also like to point friends to my my favorite Brazilian carrot cake recipe when they ask for a dessert that carries family memory like this one.
My Trusted Kitchen Tools
I use a few simple tools for this cake. I pull out a medium bowl for the dough. I keep a rolling pin ready. I use a 9 or 10 inch tart pan with a removable bottom. I rely on a heavy saucepan for the custard. I also use a whisk and a fine grater for the lemon zest.
I like a good spatula to smooth the custard. I heat milk in a pan that spreads heat evenly. And I have a sieve to strain the custard if it looks lumpy. For a small touch, I use a pastry brush to seal edges. If you want a guide for a savory snack while the tart bakes, check my club sandwich guide for a simple build you can make in minutes.
Bringing It All Together
- Mix the diced butter, flour, sugar, egg, egg yolk, vanilla, and salt in a large bowl until dough forms.
- Wrap the dough in plastic and chill it for at least 30 minutes.
- Heat the milk in a saucepan until just below boiling.
- Whisk egg yolks, sugar, cornstarch, and lemon zest in a separate bowl.
- Slowly pour hot milk into the egg mix while you whisk.
- Return the mix to the pan and cook over medium heat, whisking until thick.
- Remove the custard from heat and stir in butter and vanilla.
- Press plastic wrap onto the custard surface and cool it to room temperature.
- Preheat the oven to 350°F (175°C).
- Roll chilled dough on a floured surface to about 1/4 inch thick.
- Grease a tart pan and line it with the pastry, leaving a small overhang.
- Prick the pastry base with a fork to stop puffing.
- Pour the cooled custard into the pastry shell and spread it smooth.
- Scatter pine nuts or sliced almonds across the top.
- Bake for 30 to 35 minutes until pastry is golden and custard sets.
- Cool the tart in the pan for 30 minutes, then move it to a wire rack.
- Dust the top with powdered sugar before you serve.
Making It Your Own (Swaps & Ideas)
You can change a few things and still keep the heart of this cake. Swap lemon zest for orange zest for a sweeter scent. Use almonds instead of pine nuts if you prefer. For a lighter crust, replace half the butter with plain Greek yogurt and chill the dough a little longer. If you want a richer custard, stir in a tablespoon of cream when the custard is off the heat. For a nut-free version, skip the nuts and add a thin layer of jam under the custard. If you love a savory touch at gatherings, try serving slices with small sandwiches from my sausage and cream cheese crescent rolls recipe on the side.
How We Love to Serve It
I serve this cake at our Sunday table. I cut it into wedges and place it on a plain plate. A dusting of powdered sugar makes it look like a small gift. I often bring a pot of black coffee or a glass of sweet wine with it. It pairs well with fruit on the side. A few warm pears or a bowl of fresh berries make a bright match. For a casual snack, I slice it thin and let people take a small piece with coffee.
A Few Tips For Success
Keep the butter cold for the pastry. Cold butter gives the dough that good, crumbly texture. Chill the dough long enough so it does not shrink while baking. When you pour the hot milk into the egg mix, do it slowly and keep whisking to stop the eggs from cooking. Cover the custard with plastic directly on the surface to stop a skin from forming. Use room temperature eggs for both custard and pastry for even mixing. If the custard looks lumpy, strain it through a fine sieve before filling the tart shell. Bake until the crust is golden and the center is mostly set. It will firm up more as it cools.
Saving Some For Later
You can keep the whole tart in the fridge for up to three days. Cover it with a loose lid or plastic wrap to keep it fresh. If you cut single slices, use a cake box or a tight container and layer sheets of parchment between slices to stop sticking. You can freeze the tart for up to one month. Wrap it well in plastic and then foil. Thaw it in the fridge overnight and let it come to room temperature before serving. Do not freeze the cake with powdered sugar on top. Add that just before you serve.
