In large bowl, break up cookie dough. Stir or knead in flour until well blended. Reshape into log. If too soft to cut into slices, refrigerate up to 30 minutes.
Heat oven to 350°F. Cut cookie dough into 16 slices; cut 8 of the slices in half down the center. To make 1 rabbit cookie, place 1 whole slice on ungreased cookie sheet for head; place 2 halves on top, slightly overlapping on whole slice, for ears. Repeat to make 7 more rabbit cookies, placing 2 inches apart.
Bake 7 to 9 minutes or until edges are light golden brown. Cool 1 minute; remove from cookie sheets to cooling racks. Cool completely, about 15 minutes.
Frost cookies with frosting; decorate with icing and candies.
