If you would like to freeze these bars, cut them into squares, individually wrap them in plastic wrap, and then place them in a freezer air-tight bag. Freeze them in the bag laying flat, and then once they're frozen individually, you can move the bag upright to fit your freezer better. To enjoy the bars, move a bar to the fridge to defrost overnight. If it's still not thawed, leave it on the counter at room temperature for a few hours. Do not microwave the bars.
