Cream together shortening, margarine, cream cheese and sugar. Then add the egg yolks, vanilla and almond extract. Stir in the salt and add the flour until combined well. Wrap dough ball in plastic wrap and chill in refrigerator for at least an hour. Roll out dough on a lightly floured surface until it is 1/8” thick. Cut out with cookie cutters shaped like trees, stars, and other festive Christmas designs. Place on a cookie sheet and bake at 350° until the edges of the cookies turn just a light brown. Cool cookies on a wire rack and frost with cream cheese frosting.
Frosting
Mix together the cream, margarine and almond extract. Add the powdered sugar a little at a time mixing until it is smooth and a frosting consistency. You may need slightly less or more than 2 cups depending on conditions. Split frosting into a couple bowls and use food coloring to tint the frosting whatever colors you want. For example, you might want green for the trees and yellow for the stars. Use sugar sprinkles to decorate as desired. Frost the cooled cut-out cookies and let the frosting set prior to storing in an airtight container. Store decorated cookies in the refrigerator.
