The kids and I have a special place in our heart for Halloween sugar cookies. (My husband has a special place in his for ANY kind of sugar cookie.) They are just too fun! I use the same recipe as follows for the Heart Attack cookies.
Just mix up a bunch of your favorite Halloween colors and put each one in its own piping bag. I used a combination of Ziploc bags and disposable piping bags. Just cut the tip off and pipe away!
