Yes! You can freeze baked cookies in a ziplock bag once they are thoroughly cooled; they will stay fresh for up to two months. You can also freeze uncooked cookie balls before you bake them. Just scoop and then freeze on the pan until solid, then put them in a ziplock bag and keep frozen for up to three months. When you’re ready to use, just put them on a parchment-lined baking sheet, bake them as instructed, and then add the Hersey Kiss after baking! Keep in mind frozen cookies will need to cook in the oven for another minute or two, depending on how frozen they are.
