So, how do you actually freeze spritz cookies? It's easy peasy! Simply place the cookies on a baking sheet lined with parchment paper, and put them in the freezer until they're frozen solid. Then, transfer them to an airtight container or freezer bag, and store them in the freezer for up to 3 months.
When you're ready to bake your frozen cookies, simply place them on a baking sheet and bake them at the same temperature as you would fresh cookies. You might need to add a minute or two to the baking time, but that's it! It's a breeze to bake frozen cookies, and the result is always delicious.
