1Place waxed paper on microwavable plate. Mix all ingredients except candies until very soft dough forms.
2Drop dough by 2 rounded tablespoonfuls onto waxed paper; spread to make 3-inch circle. Make 3 cookies at a time. Decorate with candies to make monster faces, placing candies within 1/2 inch of edges.
3Microwave uncovered on High 1 minute. Turn plate 1/2 turn. Microwave 30 seconds to 1 minute longer, checking once or twice, until cookies are puffed and dry. Slide waxed paper with cookies onto wire rack. Cool 5 minutes; remove from waxed paper to wire rack. Repeat with remaining dough.
