Combine flour and baking powder. In a large mixer bowl, beat
butter or margarine until softened. Add sugar and beat until
fluffy. Then add egg, vanilla, and peppermint extract and beat
well. Add flour mixture until well blended. Divide into thirds, and
stir red food coloring into one third, green in another third, and
leave remaining third plain. Cover and chill about 1 hour or until
easy to handle.
Divide each color of dough into four parts. On a lightly floured
surface roll each into a 1/2 inch diameter rope. Place one red,
one green and one plain rope side by side. Twist together and
slice into 1/2 inch pieces for larger cookies or 1/4 inch pieces
for smaller cookies. Carefully roll into balls, blending colors as
little as possible. Then place the cookies about 2 inches apart
on an ungreased cookie sheet. Flatten pieces to 1/4 inch thick
with the bottom of a glass, dipped in sugar each time you flatten
a cookie. Repeat with remaining dough. Bake in a 375 degree
oven for 8-10 minutes, smaller cookies only 6-8 minutes.
Remove and cool.
