This recipe comes from Martha Stewart's Christmas.
1½ cups butter (no substitution)
1 ¾ cups sugar
2 large eggs, lightly beaten
3 cups sifted all-purpose flour
1 ½ cups unsweetened cocoa
¼ tsp. salt
1/3 tsp. freshly ground black pepper
Pinch of cayenne pepper
1 tsp. cinnamon
Mix together (adding sifted ingredients 1 large spoonful at a time), chill dough well, roll out 1/8” thick, cut out cookies. Bake on parchment lined cookie sheets at 350 for 8 to 10 minutes. [Martha insists on parchment, but one year I made the discovery that brown paper grocery bags cut to fit your cookie sheets work just as well].
Melt 4-6 ounces of semi-sweet chocolate and drizzle over cooled cookies for decoration.
