To be honest, I've never tried to freeze them - they always get eaten too quickly! However, there's no reason why they wouldn't freeze nicely. I would place them in layers in a rigid plastic container (Tupperware) with a sheet of baking parchment between the layers. They will freeze for months. To use, remove from the freezer, place uncovered on a plate and let them defrost at room temperature. Word of warning, they might turn sticky on the outside once defrosted, due to condensation.
