01 - Combine flour, granulated sugar, and salt in a large bowl. Incorporate cold, cubed butter using a pastry blender or fork until pea-sized crumbs form.
02 - Slowly add ice water, one tablespoon at a time, mixing just until dough comes together. Divide into two discs, wrap in plastic, and refrigerate for a minimum of 30 minutes.
03 - Set oven to 375°F. Line a baking sheet with parchment paper.
04 - Roll out one dough disc on a floured surface to about 1/8-inch thickness. Cut out 16 ghost shapes using a cookie cutter or a sharp knife.
05 - Arrange 8 ghost-shaped dough pieces on the prepared baking sheet. Spoon 1 tablespoon of jam onto each, leaving a border. Brush edges with water and cover each with a second ghost-shaped piece. Seal and crimp edges with a fork.
06 - Bake for 18 to 20 minutes until pale golden. Remove from oven and allow to cool completely.
07 - Mix powdered sugar, milk, and vanilla extract until smooth. Coat cooled pastries with icing and use mini chocolate chips or black gel to fashion ghost faces. Allow icing to set before serving.
