Ingredients

Scale
  • 1 cup all-purpose flour
  • 1/2 cup unsalted butter, cold and cubed
  • 1/4 cup powdered sugar
  • 1/2 cup finely chopped walnuts
  • 2 cups whole milk
  • 1/2 cup granulated sugar
  • 1/4 cup cornstarch
  • 1/4 tsp salt
  • 2 egg yolks
  • 1 tsp vanilla extract
  • 1 tbsp unsalted butter (for custard)
  • Whipped cream or powdered sugar, for topping (optional)

Instructions

  1. Preheat oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper.
  2. In a mixing bowl, combine flour and powdered sugar. Cut in cold butter until mixture resembles coarse crumbs.
  3. Press dough evenly into the bottom of the baking dish. Sprinkle chopped walnuts evenly over the crust and press gently.
  4. Bake for 20–22 minutes until golden. Remove and let cool completely.
  5. In a saucepan, whisk together milk, sugar, cornstarch, and salt. Cook over medium heat, whisking constantly until thickened, about 6–8 minutes.
  6. In a small bowl, whisk egg yolks. Slowly add a few spoonfuls of the hot milk mixture to temper, then whisk the yolks into the pan.
  7. Continue cooking for 2–3 more minutes, then remove from heat. Stir in vanilla and 1 tbsp butter until smooth.
  8. Pour custard over cooled crust. Smooth the top and refrigerate for at least 4 hours or until set.
  9. Cut into squares and top with whipped cream or a dusting of powdered sugar if desired.

Notes

  • For a deeper flavor, toast walnuts before adding to the crust.
  • Chill overnight for clean, firm slices.
  • Can be made a day ahead and stored in the fridge.
