I love these cookies! They are a pretty pink cookie; especially on the inside, and since they are peppermint-y, they remind me of Christmas. I like how they look displayed in the center of the cookie platter.
In a medium size bowl, combine the flour and cornstarch, then set the bowl aside.
In a large bowl cream together until light and fluffy, the butter and the 1/2 cup of powdered sugar.
Mix in the peppermint extract.
Gradually add the dry ingredients into the creamed mixture, and mix well.
Thoroughly mix the food coloring into the cookie dough.
At this point, I refrigerate the cookie dough (in a bowl covered with aluminum foil), so the dough firms up enough to shape into dough balls. This may take anywhere from 1-2 hours. (I let mine set overnight in the refrigerator, and bake mine the next day when I have the time.) I then let the dough sit on the counter (in the bowl covered with foil) for about an hour, before making the cookies.
When ready to bake the cookies, heat your oven to 350º F. And in a shallow bowl, add the 1-1/2 cups powdered sugar. Set the bowl aside. (Use more powdered sugar if need be.)
Line baking sheets with parchment paper.
Shape the cookie dough into 1-inch balls. (I used a small cookie scoop which is equivalent to 1 tablespoon to make each cookie, then shape the cookie dough into 1" balls.)
Place the dough balls 2-inches apart on the parchment lined baking sheets.
Place baking sheets in the oven, and bake for about 13 minutes (until the bottoms of cookies are lightly brown) then remove from oven, and let cookies set 2 minutes on baking sheet before removing them to a wire rack.
Gently roll the warm cookies in the powdered sugar, then place the powdered coated cookies back on the wire racks.
Once the cookies have cooled slightly, gently roll them again in the powdered sugar, and place them back on the wire racks to finish cooling.
Note: I had noticed after baking 2 sheets of cookies, the cookie dough was becoming soft, so I place the remaining cookie dough back in the refrigerator, so it could firm up a bit, then finished baking the cookies. Also, once these cookies had cooled, I then place them in a container (such as Tupperware or Rubbermaid) and in the freezer, as these cookies do keep well if stored in the freezer. I then only take out a few cookies at a time when I want to serve them.
