Cookie recipes that do not harden after cooling?

I have been trying to bake cookies for a gift basket for the men at my husband’s work. Every recipe I have tried since so far have hardened after cooling the cookies. Am I doing something wrong or does someone have recipes for Oatmeal Raisin, Chocolate chip, and peanut butter cookies that stay soft after cooling? The men at his work like soft chewy cookies not hard ones.
