You can freeze both unbaked and baked snickerdoodle cookies. Freezing Unbaked Dough Shape the dough into balls and place them on a baking sheet, ensuring they don't touch. Freeze for about 30 minutes and then transfer to a freezer bag. It's best to freeze the dough without the cinnamon-sugar coating and store for up to 2 months. To bake, allow the dough to thaw for 15 minutes, roll in cinnamon sugar, and follow the original baking instructions. Freezing Baked Cookies For baked cookies, place them in an airtight container with parchment or wax paper between each layer. They'll keep for up to 2 months. To enjoy, let the cookies thaw for about 20 minutes. If you prefer them warm, reheat in a 275°F oven for 10-12 minutes.
