6. To freeze: transfer cooked waffles to wire racks and cool completely. Line a baking sheet with parchment paper and place a single layer of cooled waffles on it. Cover that layer with another sheet of parchment and add another single layer of waffles. Repeat into as many layers as you need, then freeze the baking sheet for 2 hours, or until the waffles are solid.
7. After freezing, transfer the frozen waffles to a freezer-safe bag, remove excess air, seal, and return to the freezer.
