Yes, these muffins can be frozen. I often freeze muffins for my family. I remove the liners, wrap each muffin in plastic wrap, and then put the muffins in a Ziploc bag. I label the bag with the name of the recipe and the date I made them. Then, the night before we’re going to have the muffins for breakfast, I take out however many we need and leave them on the counter to thaw overnight.
