Room Temperature: You can store your decorated or undecorated gingerbread cookies in an airtight container for up to 1 week at room temperature. Refrigerator: You can also store them in the fridge for up to 12 days as long as they are stored properly in a sealed container. Freezing Gingerbread Cookie Dough: You can freeze the dough as a flattened disc or roll and cut shapes. Just be sure and wrap in plastic, then store in a freezer bag or another airtight container for up to 2 months. To thaw, transfer to the fridge overnight. If you have frozen cut-out shapes, you can transfer to baking sheets and bake them immediately. Otherwise, let the dough come to room temperature for about 30 minutes, then roll, cut and bake as directed. Freezing Baked Gingerbread Cookies: You can also freeze baked cookies for up to 3 months, whether they have been decorated or not. Be sure to separate them with layers of parchment paper inside an airtight container and store them frozen for up to 3 months. To thaw, you can thaw either in the fridge or at room temperature.
