Classic Walnut Shortbread Pie

The secret to this perfect shortbread is cold butter and a light touch. Unlike bread, we aren't aiming for elasticity but a crumbly, melt-in-your-mouth texture. The rich, moist walnut filling perfectly balances the crisp pastry crust.

Instructions

1

In a food processor or by hand, quickly cut the cold butter into the flour, confectioners' sugar, and salt until it resembles wet sand.

Tip: Keep pea-sized bits of butter visible. These melt during baking to create steam pockets, resulting in a flaky crust.
2

Add the egg yolk and ice water, mixing until a dough ball forms. Wrap in plastic and chill in the fridge for 30 minutes.

Tip: Chilling relaxes the gluten proteins, making the dough easier to roll out and preventing shrinkage.
3

Make the filling: Heat the milk, sugar, and cinnamon in a saucepan until hot. Stir in the ground walnuts. Remove from heat and let cool.

Tip: Heating the milk helps soften the walnuts and release their natural oils for a more intense flavor.
4

Roll out 2/3 of the dough and line a buttered pie dish. Spread the walnut filling evenly over the bottom.

Tip: Prick the bottom crust with a fork to allow steam to escape and prevent bubbling.
5

Cut the remaining dough into strips to create a lattice top. Brush with beaten egg and bake at 350°F (180°C) for 35-40 minutes.

Tip: The egg wash ensures a glossy, golden-brown finish.

Recipe FAQ

Why did the crust shrink?
The dough likely wasn't chilled enough, or the butter got too warm during mixing. Always keep ingredients cold to prevent shrinking.
