Preheat oven to 375 degrees F.

Dump cookie mix into a large mixing bowl. Add softened butter, egg and one tablespoon of flour.

Using an electric mixer or your hands, mix until it forms a soft dough.

Divide dough in half. Add peppermint extract to one half. Knead it into the dough until well-incorporated. Add a tablespoon of flour if dough is too sticky.

Add red food coloring to the other half. Start with 4 drops of food coloring, and add more until you get a nice, deep pink color. Add a tablespoon or two of additional flour if the dough is too sticky.

Pinch off a teaspoon of pink dough and a teaspoon of white dough. Stick together and form a ball.

Important: Don't knead them together, or the dough will all turn pink. You want a nice candy cane stripe.

Place balls 1 inch apart on an ungreased cookie sheet. Bake 10-15 minutes, until cookies are lightly browned on the bottom.

Remove from oven and immediately press a Hershey kiss in the middle of each cookie.
