Sweetheart Thumbprint Cookies
Tell your sweeties, "You're my jam!" in a way that'll turn them into jelly. Simply roll butter-cookie dough into balls, and press the handle end of a spoon into each twice to make a V that expands as it bakes (genius!). Then sprinkle with sanding sugar, fill the indentations with warmed preserves, and give your heart away again and again.
