Sour Cream Sugar Cookies

I saw the picture (page 164) of these cookies in 2009 Taste of Home Annual Recipes. I know this recipe was what I wanted to make for Valentines Day. The only thing, I wasn't sure if the frosting recipe that was posted with the cookie recipe would hardened. I flipped and few more pages and found the recipe that I knew would do. The cookies are plain, not overly sweet. The frosting brings in the sweetness without being overly sugary.
