Preheat the oven to 375 °F (190 °C).
Line a baking sheet with parchment paper.
Take half of the pie crust (or 1 store-bought pie crust) and roll out the pie crust 1/8" thick between two pieces of parchment paper. You can alternatively use a lightly floured countertop, but I think parchment is easier.
1 batch gluten-free pie crust
Cut out as many mummies as you can. I used a 4" gingerbread man cookie cutter. Place them on the prepared baking sheet about 1" apart.
Roll together the remaining bits of dough, roll it out again, and cut out more mummies. You should now have the bottom part of about 20 mummies. The number will depend on your pie crust, how thick you roll it out, and your cookie cutter size.
Fill each with about 1 teaspoon of jam.
7 tablespoons (125 grams) strawberry jam
For the vegan option, brush a little cashew milk all around the sides of a mummy and then place another mummy cut-out on top. For the non-vegan option, brush the egg wash all around the sides of a mummy and then place another mummy cut-out on top.
1 large egg
Press down the edges to make sure the jam doesn't ooze out.
Brush the tops of the mummies with the egg wash (skip this for vegan) and poke the mummies with a fork to create a vent.
Bake for 12-15 minutes or until the mummies have browned nicely. Let them cool completely on the baking sheet before you ice them, about 1 hour.
Prepare the icing. In a small bowl, mix together the icing ingredients, using the lower amount of milk and almond extract. It shouldn't be too runny. You need it thick enough to pipe. Add more milk and almond extract, if needed.
3/4 cup (80 grams) powdered sugar, 2 to 4 teaspoons milk, 1/8 to 1/4 teaspoon almond extract
Transfer the icing to a piping bag fitted with a small round tip or cut the end off of a Ziploc.
Pipe the frosting over the top of each hand pie to create the mummy look. Let the frosting harden before placing in an airtight container.
These are best served on the day of preparation. If you need to store them longer than that, keep them in the fridge. If transporting these, I recommend not stacking them. The icing firms up, but it could still be damaged if stacked.
