Buttery Yeast Spritz Cookies

In my never ending search for new cookie press recipes I fell upon these Buttery Yeast Spritz Cookies. Yeast in cookies? Truly a different ingredient and I have to say, these cookies are very light, very tender, and have a huge butter flavor! I think this recipe is very close to bakery style cookies, and the sprinkling of colored sugar adds a nice little extra sweet touch. So, if you'd like to add a new cookie recipe to your list of things to try... How about bringing the cookie press out of storage, choosing a flower disc, and baking up a colorful spring bouquet:@)
