Yes, you can definitely freeze homemade snickerdoodle cookies. There are actually two ways to freeze snickerdoodles. Here are your options: Freeze baked cookies- bake the cookies completely and let them cool. Place the cookies in a zippered freezer bag and freeze the cookies for up to two months. Anytime you want a cookie, simply take one out of the bag, let it thaw at room temp and enjoy. You can also pop a frozen snickerdoodle into the oven for about 2 minutes to reheat it to its original glory.  Freeze snickerdoodle cookie dough- Make the cookie dough through the end of the recipe, rolling the cookie dough balls in cinnamon and sugar. Place the cookie balls in a gallon-sized zippered freezer bag and seal tightly. Store the cookies in the freezer for up to three months. To bake, place the frozen cookie dough on a parchment-lined cookie sheet. The cookie dough will only take about a minute longer to bake than directed in the recipe.
