Yes, these bars can be frozen for up to 2 months, both as individual bars or as a whole pan. If you freeze them as a whole, I highly suggest lining your baking pan with parchment paper to make removing them from the baking pan easier. You can pre-slice the bars but leave them all connected, then tightly wrap them in plastic wrap and then a layer of heavy-duty aluminum foil. You will need to thaw them in the refrigerator before serving.
