Chocolate Pie Crust

Preheat the oven to 350 degrees F (175 degrees C).

Beat flour, confectioners' sugar, walnuts, butter, and cocoa together in a large mixing bowl until a soft dough forms.

Press dough into the bottom and up the side of an ungreased 9- or 9 1/2-inch fluted tart pan with a removable bottom.

Bake crust in the preheated oven until puffed, 12 to 14 minutes.

Cool crust completely in the pan on a wire rack, about 1 hour.
