After the pancakes have been cooked, let them cool to room temperate on a wire rack in one even layer. The wire rack is important because it will keep the pancakes cooled evenly and keep the bottom of the pancakes from accumulating moisture. Place cooled pancakes into the freezer and let them freeze for about 2 hours. Once pancakes have been frozen, transfer them into a large zip-lock freezer bag. Seal, label, and place back into the freezer.  To reheat pancakes: You can reheat pancakes either in the microwave or in a toaster. In the microwave, simply place a pancake on a plate, cover it with a microwave lid, and reheat for about 60 seconds. To reheat in the toaster, first make sure that pancakes are small enough to fit well. Reheat them in a toasted on a slower/lower setting to it gets a chance to reheat thoroughly.
