I found this recipe several years ago. I have altered some; you can stir in a 1/2 cup of slivered almonds after mixing all the other ingredients if you like. The end product is actually a thin wafer-like cookie. They are very tasty and very quick to throw together.
3/4 cup margarine or butter, softened
1/2 cup powdered sugar
1 cup all purpose flour
1/2 cup instant cocoa mix (this is hot chocolate mix, not cocoa powder!)
Combine butter and sugar, then stir in flour and cocoa mix. Heat oven to 325 degrees. Shape into 1" balls (place dough in fridge for a few minutes if it is too soft to shape) and place on ungreased cookie sheet. Bake for about 20 minutes. Remove from oven and sprinkle with powdered sugar. Once cool, sprinkle again with sugar.
