Preheat your oven to 350°F if you have not already preheated your oven for making a pie. If your pie bakes at a different temperature, please just use that temperature.
If you are using cinnamon sugar, combine the cinnamon and sugar in a small bowl.
1 tablespoon cinnamon, ¼ cup sugar
Combine your pie dough scraps and roll them out into a circle ¼ to ⅛ inch thick if you want cookies that look like rugelach or into a rectangle if you want spiral cookies. See the Tips and Tricks for examples.
¼ pound leftover pie dough
Sprinkle or spread your filling over the dough, leaving a small border around the edges.
1 to 2 tablespoons cinnamon sugar, Nutella or other filling
If you are making rugelach, cut the circle into wedges and roll your cookies from the outside to inside of the circle. If you are making spirals, roll from the short edge of the rectangle and slice your roll into ¼ inch cookies.
Place the cookies on a baking sheet lined with parchment paper or a silicone mat. They will not spread so do not need much spacing.
Bake for 10 to 15 minutes, depending on the size of your cookies. If you are using a different oven temperature than 350°F, just keep an eye on the cookies and take them out when they are starting to become light brown.
Let cool on the baking sheet. Pie crust cookies can be stored at room temperature for about one week or frozen for three to six months.
