Heat oven to 375°F. In medium bowl, stir cookie mix, oil, water and egg until dough forms.
Shape dough into thirty-six 1-inch balls; roll in sugar. Place 2 inches apart on non-greased cookie sheets.
Bake 10 to 12 minutes or until light golden brown. Immediately press 1 chocolate in center of each cookie. Remove from cookie sheets. Cool completely, about 20 minutes. Decorate as desired using remaining ingredients.
