Combine first 3 ingredients in a small bowl and set aside.
Beat butter and cream cheese until creamy; gradually add flour, mixing until
well blended. Shape dough into a ball; wrap in plastic wrap, and chill 30 minutes.
Divide dough in half; place one portion between 2 sheets of lightly floured wax
paper, and roll into a 10-inch square (about 1/8 inch thick). Brush with egg, and
sprinkle with half of sugar mixture. Cut into 5 x 1/2-inch strips; twist strips,
and place on ungreased baking sheets.
Repeat with remaining dough and sugar mixture.
Bake at 350 degrees F for 10 to 12 minutes or until golden and crisp.
