How do you keep rice crispy treats fresh longer?

Your best bet is to avoid sticking them in the fridge or freezer. Rice crispy treats will actually taste best if they're stored at room temperature. or quicker, easier access, go for smaller squares that you can just grab and eat. Choose a container that will hold all of the leftovers without leaving too much extra space for air at the top. The less air space, the better. Stack the treats into the container or baggie in single layers. If you're using a plastic bag, squeeze out as much of the air as you can. If you're stacking multiple layers, place a sheet of wax paper between each layer to prevent sticking. The wax paper will act as a buffer and keep the rice crispy treats from bonding and sticking together. Store the container on the counter, in a cupboard, or anywhere that will stay room temperature for up to 3 days. Any longer than that and they could spoil.
