Preheat oven to 375F (190C) and line a baking sheet with parchment paper.

Prepare egg wash by thoroughly whisking together egg and water in a small dish, set aside.

In a separate small dish, whisk together sugar and cinnamon.

Roll out pie dough or pie scraps to be just under ¼” (0.6cm) thick (if using store bought pie dough it will already be this thick, no need to roll).

Use cookie cutters to cut out cookies and transfer them to baking sheet, spacing at least 1” (2.5cm) apart.

Use a pastry brush to lightly brush all over the surface of each cookie with egg wash.

Sprinkle generously with cinnamon/sugar mixture.

Transfer to the center rack of 375F (190C) oven and bake for 9-11 minutes, or until cookies are just beginning to turn light golden brown. Allow to cool on baking sheet for several minutes before enjoying.
