- In a large bowl, combine the sugar, butter, cream cheese, salt, almond and vanilla extracts, and egg yolk. Beat until smooth. Stir in flour until well blended. Chill the dough for 8 hours, or overnight.
- Preheat oven to 375 degrees F (190 degrees C).
- On a lightly floured surface, roll out the dough 1/3 at a time to 1/8 inch thickness, refrigerating remaining dough until ready to use. Cut into desired shapes with lightly floured cookie cutters. Place 1 inch apart on ungreased cookie sheets. Leave cookies plain for frosting, or brush with slightly beaten egg white and sprinkle with candy sprinkles or colored sugar.
- Bake for 7 to 10 minutes in the preheated oven, or until light and golden brown. Cool cookies completely before frosting.
