1/2 cup sugar
3 tablespoons canola oil
1 egg
1 cup all-purpose flour
1/4 cup baking cocoa
1/2 teaspoon baking soda
1/4 teaspoon salt
2 tablespoons fat-free milk
FILLING:
2 tablespoons butter, softened
1-1/3 cups confectioners' sugar
1/8 teaspoon mint extract
4 drops green food coloring, optional
4 teaspoons fat-free milk
In a large bowl, beat sugar and oil until crumbly. Add egg; beat for 1 minute. Combine the flour, cocoa, baking soda and salt. Gradually beat into sugar mixture. Add milk and mix well. (Dough will be sticky.) With lightly floured hands, roll dough into 3/4-in. balls.
Place 2 in. apart on baking sheets coated with cooking spray.
Flatten slightly with a glass coated with cooking spray. Bake at 400° for 4-5 minutes or until edges are set and tops are cracked. Cool for 2 minutes before removing to wire racks to cool.
In a small bowl, combine butter and confectioners' sugar until crumbly. Beat in extract, food coloring if desired and milk. Spread on the bottoms of half of the cookies; top with remaining cookies. Yield: 1-1/2 dozen.
