The pancake sandwiches may be frozen and eaten at a later time. Follow the instructions as is and then wrap the pancake sandwiches very tightly in foil. Place the foiled parcels into a large airtight zipped bag or freezer-safe container. Freeze for up to 3 months. When you are ready to eat, just remove one of the sandwiches from the freezer, and heat in a 400 degree F oven for 15-20 minutes or until the sandwich is warmed through.
