1. In a saucepan over low heat, cook margarine and sugar until melted. Add chocolate chips and stir until partially melted. Remove from heat and stir until chips are completely melted. Pour into a bowl. Let Stand for 10 minutes to cool slightly.

2. With a mixer at high speed, beat in eggs one at a time. Reduce speed to low and add dry ingredients, beating until just blended. Cover and Chill for 1 hour.

3. Preheat oven to 350 degrees. Line 2 cookie sheets with foil. Roll teaspoonful of dough into balls; place 2 inches apart on the cookie sheets. Bake for 12-13 minutes. Remove from the oven and place mint on top. Allow to soften; then swirl the mint. Makes about 80 cookies.
