Button cookies - love this idea! You need a shortbread (butter cookie) recipe, two biscuit cutters (one slightly smaller than the other), and a drinking straw (to make the holes). Aww, cute as a button!
For our recent anniversary, I offered to make my husband a batch of whatever cookies he chose. He picked these checkerboard butter cookies, a combination of my Basic Butter Cookie recipe, plus a Mexican Chocolate variation.
