Thin Mint Cookies Recipe

In a large bowl beat 1/2 cup butter or margarine until creamy. Add the sugar and beat until mixed well. Beat in egg and mint extract.

Sift flour cocoa and salt together into a small bowl. Add flour mixture by halves into creamed mixture beating well after each addition.

Divide dough in half. On lightly floured surface roll dough into two 1 1/2 inch diameter cylinders. Wrap each cylinder in waxed paper and refrigerate 5 hours.

Preheat oven to 350 degrees F (175 degrees C). Thirty minutes prior to baking place both cylinders in freezer.

Remove one cylinder at a time and slice 1/4 inch thick pieces with very sharp knife. Place on cookie sheets about 1 1/2 inches apart. Bake 10 to 12 minutes.

Melt 1/4 cup butter or margarine and the semisweet chocolate in a double boiler or in the microwave. Drizzle over warm cookies. Place on wire racks and let cool and harden completely.
