1 c. sugar
1/4 c. margarine or butter (room temperature)
1/4 c. shortening
1/2 tsp vanilla flavoring
1 egg
2 oz. melted and cooled baking chocolate (unsweetened)
1 3/4 c. all purpose flour
1 tsp. baking powder
1/8 tsp salt
1/2 c. peanuts (finely chopped)
Combine first five ingredients in large bowl and mix on medium speed or stir by hand with spoon. Stir in chocolate. Add flour, baking powder and salt. Cover and chill until firm, approximately 2 hours. Heat oven to 400 degrees. Divide dough in two and roll each into a 12 x 9 rectangle onto a lightly floured surface. Sprinkle each prepared rectangle with half of the chopped peanuts gently pressing into the mixture. Cut dough into 3 inch squares and place 2 inches apart on ungreased baking sheet. Cut squares from each corner to almost the center. To resemble pinwheel, fold every other point. Bake approximately 6 minutes or until set. Transfer from baking sheet to wire rack.
