If you have leftover waffles that you would like to freeze, place them in a freezer safe container and store in the freezer for up to 3 months. If you don't want the waffles to stick together, you can place a piece of parchment paper in between each one, or freeze them on a baking sheet for 2-3 hours before transferring to a bag or container. To reheat, pop them in the toaster or warm them up in the oven until heated through!
