by

Torta della Nonna (Grandma’s Cake)

A timeless Italian classic — this rustic yet elegant tart features a buttery, crumbly pastry shell filled with rich lemon-scented custard, topped with pine nuts and a dusting of powdered sugar. It’s the dessert Italian grandmothers have been making for generations.

Ingredients

For the Pastry (Pasta Frolla):

· 2 cups (250g) all-purpose flour
· ½ cup (100g) granulated sugar
· ½ cup (115g) cold unsalted butter, cubed
· 1 large egg
· 1 large egg yolk
· 1 tsp vanilla extract
· Zest of 1 lemon
· Pinch of salt

For the Custard (Crema Pasticcera):

· 2 cups (500ml) whole milk
· ½ cup (100g) granulated sugar
· 4 large egg yolks
· ¼ cup (30g) cornstarch
· 1 tsp vanilla extract (or vanilla bean paste)
· Zest of 1 lemon

For Topping:

· ⅓ cup (45g) pine nuts (or slivered almonds)
· Powdered sugar for dusting

Instructions

Step 1: Make the Pastry (Pasta Frolla)

  1. In a food processor or large bowl, combine flour, sugar, lemon zest, and salt.
  2. Add cold butter cubes and pulse (or rub in with fingertips) until mixture resembles coarse breadcrumbs.
  3. Add egg, egg yolk, and vanilla. Mix just until dough comes together. Do not overwork.
  4. Form dough into a disc, wrap in plastic, and refrigerate for at least 1 hour (or up to 24 hours).

Step 2: Make the Custard

  1. In a medium saucepan, heat milk and lemon zest over medium heat until just simmering (do not boil).
  2. In a separate bowl, whisk egg yolks and sugar until pale and thick (about 2 minutes).
  3. Whisk in cornstarch until smooth.
  4. Slowly pour half the warm milk into the egg mixture while whisking constantly (to temper the eggs).
  5. Pour the mixture back into the saucepan with the remaining milk.
  6. Cook over medium heat, whisking constantly, until mixture thickens into a pudding (about 3–5 minutes).
  7. Remove from heat, stir in vanilla, and let cool slightly.
  8. Press plastic wrap directly onto the surface of the custard (to prevent skin from forming) and refrigerate until completely cooled.

Step 3: Assemble the Tart

  1. Preheat oven to 350°F (175°C). Grease a 9–10 inch (23–25cm) tart pan with removable bottom.
  2. Remove pastry dough from refrigerator. Let sit for 5–10 minutes to soften slightly.
  3. On a lightly floured surface, roll out about ⅔ of the dough into a round about 12 inches wide.
  4. Gently transfer dough to the tart pan, pressing it into the bottom and up the sides. Trim excess dough from the rim.
  5. Pour cooled custard into the pastry shell and spread evenly.
  6. Roll out the remaining dough and cut into strips (for a lattice top) OR roll into a solid round to cover the tart (cut vents in top).
  7. Place the top crust over the custard. Press edges to seal and trim excess.
  8. Brush top with a little milk or beaten egg (optional for shine).
  9. Sprinkle pine nuts evenly over the top.

Step 4: Bake

  1. Place tart pan on a baking sheet to catch any drips.
  2. Bake for 35–45 minutes until the crust is golden brown and the custard is set (it should jiggle slightly but not be liquid).
  3. Let cool completely in the pan on a wire rack.

Step 5: Serve

  1. Remove the tart from the pan carefully.
  2. Dust generously with powdered sugar just before serving.
  3. Slice and serve at room temperature or slightly chilled.

The Story Behind Torta della Nonna

This beloved dessert hails from Tuscany, specifically the region around Florence and Prato. While the name means “Grandma’s Cake,” most versions today use a creamy custard filling — but the original Torta della Nonna was actually filled with ricotta and sometimes stale bread crumbs (a humble, peasant-style dessert).

The modern custard version became popular in the mid-20th century. Legend says a pastry chef in the 1930s created it and named it after his grandmother, who taught him the importance of simple, quality ingredients.

Pine nuts on top are traditional — they add a delicate, nutty crunch that perfectly complements the soft custard.

Pro Tips for Success

Do This Avoid This
Keep pastry dough cold Warm, soft dough that sticks
Blind bake only if very thick crust Overbaking before filling
Cool custard completely before filling Warm custard melting the pastry
Use whole milk for richest custard Low-fat milk (thin, less creamy)
Dust with powdered sugar right before serving Dusting too early (sugar absorbs into crust)
