This easy, Halloween-inspired recipe can be made ahead and served later as a scary-good party dessert.
Preheat the oven to 350ºF.
Add the pumpkin, sweetened condensed milk, cinnamon, ginger, nutmeg and a pinch of salt to a medium bowl and stir to combine.
Roll out 1 pie crust on a lightly floured surface with a rolling pin to form a rectangle about 9 inches by 12 inches. Square off the crust with a knife, reserving the scraps for decorating. Cut the pie crust into 6 equal rectangles, each about 3 inches by 6 inches. Transfer to a parchment-lined baking sheet.
Roll out the other pie crust to the same thickness as the first. Cut into thin strips about 1/4 inch wide and 7 inches long. Repeat with the reserved dough scraps. Transfer the strips to a parchment-lined baking sheet.
Add 1 heaping tablespoon of the filling to the center of each rectangular crust. Use the back of a spoon to spread out the filling, leaving about a 1/2-inch border around the edges.
Lightly beat the egg with 1 tablespoon water in a small bowl. Use a pastry brush to brush the edges of the pies with the egg wash. Layer the strips of dough, varying the angle of each strip to create a “mummy” look. Seal the edges with a fork and use a paring knife to trim the overhang. Lightly brush the tops of the hand pies with the egg wash. Add 2 raisins to each hand pie for the eyes.
Bake, rotating the pan halfway through for even color, until golden brown, 20 to 25 minutes. Cool on a baking rack slightly, about 5 minutes.
Serve as is or decorate with a simple icing. Combine the confectioners’ sugar in a small bowl with 1/2 teaspoon water. Stir until smooth and glossy. Transfer the icing to a resealable plastic bag and snip off the corner. Pipe the icing onto the hand pies using the stripes of pie crust as a guide. Serve.
