I do not recommend freezing cooked churros. However, you can freeze uncooked churros. To do so, simply pipe the churro dough into a single layer on a baking sheet lined with parchment paper. Make sure to space them, so they don't touch each other. Then cover it with plastic wrap and place it in the freezer to flash freeze. When they’re hard frozen, transfer the uncooked churros to a Ziploc bag or freezer-friendly container and freezer for up to 2 months. To cook, simply fry them straight off the freezer. Do not thaw.
