YES! Scoop mashed potato pancake batter onto a cookie sheet lined with parchment paper. Flatten out like you are going to fry them in the skillet. Place in the freezer for 30 minutes to freeze solid. Place in a freezer-safe container once frozen individually and store for up to 6 months. To make: place pancake straight from the freezer in a skillet over medium-low heat with butter. Cook on one side for 5-7 minutes or until golden brown and a crispy outer layer. Flip and fry for another 2-3 minutes until that side is golden brown and cooked all the way through. Repeat with as many as desired.
