Preheat the oven to 375F.

Combine the butter, flour, egg, and sugar cookie mix together to form the cookie dough. Split in half.

Place half in a bowl, place a couple of red food coloring drops, and mix thoroughly. Repeat for the other half and green food coloring.

Roll out the red dough to be approximately 1/8" thick in a long rectangle on wax paper. Trim the sides to get an even line, add the extra dough on to the end and roll out. Repeat for green so they are approximately the same size rectangles.

Set in the fridge to cool down - approximately 10 minutes.

Once cooled, press sprinkles into the red dough by rolling over it. Peel off the green dough and lay on top of the red dough.

Place sprinkles on top of the two doughs and press the sprinkles in by rolling over it.

Roll the two doughs together. If it starts to crack/bend instead of a smooth roll, just keep going and smooth out as you go along.

Once the two doughs are rolled together to form a log, trim the ends to give a straight line on each end. Place sprinkles on wax paper or cookie sheet and roll the log in it.

Cut the log in approximately 1/4"slices, reshape if necessary to be more of a circle, and place on a slightly greased cookie sheet. Place cookies approximately an inch or so apart. Place sprinkles on top and press down by rolling over it.

Bake for 5-7 minutes or until firm.
