My mother makes these cookies every year and they are my absolute favorite! Growing up she’d make them ahead of Christmas and store them in the freezer with a note on the outside of the container saying “Do not eat before Christmas!” and a note on the inside saying “I mean it!”.

•  1 1/2 c powdered sugar
• 1 1/4 c butter, softened
• 1 egg
• 3 c all purpose or cake flour
• 1/4 c cocoa powder
• 1/4 tsp salt

1. Mix powdered sugar, butter or margarine, and egg. Mix in the flour and salt.
2. Divide dough into halves,  mix in cocoa powder to one half of the dough. Cover and refrigerate both doughs for 1/2 hour.
3. Roll each dough into a rectangle, 16×9 inches on a lightly floured board.
4. Place chocolate dough on plain dough and roll doughs to 3/16 inch thickness. Roll up tightly, beginning at the wide side. Wrap, and refrigerate the dough at least 8 hours and  up to six weeks.
5. Preheat the oven to 400 degrees.
6. Cut the rolls into 1/8-inch slices. Place about 1 inch apart on ungreased cookie sheet.
7. Bake until set, about 8 minutes. Immediately remove from cookie sheet, cool, and enjoy.
