1Heat oven to 375°F. In large bowl, beat granulated sugar, butter, vanilla and egg with spoon until smooth. Stir in flour.
2Shape dough into 1-inch balls. (If dough is too soft to shape, cover and refrigerate at least 1 hour.) Roll balls in colored sugars. On ungreased cookie sheet, place about 2 inches apart.
3With kitchen scissors or paring knife pointing down, snip each ball in half, cutting three-fourths of the way through dough; cut each half into 3 wedges for petals.
4Bake 10 to 12 minutes or until set. Cool 1 minute; remove from cookie sheet to cooling rack. Immediately press 1 candy into each cookie. Cool completely.
