I make these for my kids lunch, and they are the envy of all their friends. I even send extra, knowing that their friends will eat some too They are quite nutritious as well, and the recipe can be doubled easily. I usually make a double recipe and put them on a pizza pan or cookie sheet. I let them sit in the freezer for a couple hours, then move them to a resealable plastic bag. Then I pull out as many as I need. I pack their lunches in the morning, and the peanut butter balls are thawed by lunchtime.
