Chocolate Cookie Slices

One of my personal favorites, but, they always turn out a bit dry.
I usually don't bother frosting these, might help with the dryness.

8 min 400°F

YIELD: 8 dozen cookies REFRIGERATE
1 ½ cups powdered sugar
1 ¼ cups margarine or butter, softened
1 egg
3 cups all-purpose flour
½ cup cocoa
¼ tsp. Salt

Mix powdered sugar, margarine and egg. Stir in flour, cocoa and salt. Cover and refrigerate 1 hour. Divide into halves. Shape each half into roll about 1 ½” in diameter. Roll in pecans. Wrap and refrigerate at least 8 hours but no longer than 6 weeks.
Heat oven to 400°F. Cut rolls into 1/8” slices. (If dough crumbles while cutting, let warm slightly.) Place about 1” apart on ungreased cookie sheet. Bake about 8 minutes. Remove immediately from cookie sheet; cool. Frost with fudge frosting if desired.
