Combine 1 cup butter, sugar and egg in large bowl. Beat at medium speed, scraping bowl often, until creamy. Add orange juice and vanilla; mix well. Reduce speed to low; add flour and baking powder. Beat until well mixed.

Divide dough into thirds; wrap in plastic food wrap. Refrigerate until firm (2 to 3 hours).

Heat oven to 400°F. Roll out dough on lightly floured surface, one-third at a time (keeping remaining dough refrigerated), to 1/8- to 1/4-inch thickness. Cut with 3-inch cookie cutters. Place 1 inch apart onto ungreased cookie sheets; sprinkle with decorator sugar. Bake for 6 to 10 minutes or until edges are lightly browned. Cool completely.
