For cookies, preheat oven to 375 degrees. In a large bowl, cream
butter, corn syrup and sugar until fluffy. Add egg and vanilla; beat
until smooth. Tint orange. In a medium bowl, stir together flour,
baking soda, and salt. Add dry ingredients to creamed mixture. Stir
until a soft dough forms. Divide dough in half. On a lightly floured
surface, use a floured rolling pin to roll out each half of dough to
1/4" thickness. Use a 1&1/2" round cookie cutter to cut out cookies.
Place cookies 1" apart on a greased baking sheet. Bake 5-7 minutes or
until edges are light brown. Transfer to a wire rack to cool
completely. For filling, beat all ingredients together in a medium
bowl until smooth. Spread filling generously on half of cookies; top
with remaining cookies. For each yo-yo string, cut a 20" length of
string. Tie one end into a small loop. Wrap remaining end around
cookie. Store in an airtight container. Remove string before eating
cookie. Makes about 3 dozen cookies.
