Mix together shortening, margarine, Splenda Granulated Sweetener, egg and molasses in a large mixing bowl.
Sift dry ingredients together and add to shortening mixture. Mix thoroughly.
Chill dough in refrigerator until firm (approximately 2 hours).
Preheat oven to 350 degrees F.
Form dough into 30 balls, approximately 1 level tablespoons each. Place cookies on ungreased cookie sheet and pat down gently with fork making a criss-cross pattern.
Bake cookies in the center of the preheated 350 degrees F oven for 10-12 minutes. Do not overbake. Cookies will look chewy when they come out but will become crisp. Cool cookies on wire cooling rack.
