Yes. Make sure the muffins are fully cool before wrapping. Place the muffins in a freezer-safe plastic bag and suck the air out of the bag using a straw. Be sure to remove all air in the freezer-safe bag before freezing the muffins. Alternatively, tightly wrap each muffin with plastic wrap and then foil and place it in the freezer. Store muffins for up to 3 months in the freezer. To eat, thaw muffins at room temperature without unwrapping. If you are only thawing one muffin, remove the muffin from the freezer bag and place it in another bag to thaw. While this may seem tedious and wasteful, it prevents moisture from forming on the surface of the muffin. No one likes a sticky muffin!
