Grandma's Sour Cream Sugar Cookies

"These Sour Cream Sugar Cookies are soft and fluffy with just the right amount of sweetness — they’re perfect with or without frosting and make a great freezer-friendly holiday cookie! These Sour Cream Cookies are not the difficult, finnicky cookies that require hours of rolling, cutting, baking, and decorating. They are a soft sugar cookie made with sour cream, and they have a fluffy, delicate texture that I find much more appealing. A simple colored frosting and maybe a few sprinkles is really all they need to make them extra special for Christmas, though they are easy enough to make for any occasion…. Or no occasion. Sometimes you just need a cookie!"
