I bought ready-made cookie dough and tried to make "candy corn" cookies. You can't really see the yellow too well but the boys still thought they were cool.
Just divide the dough into thirds and dye two of the three. Roll all of them up and put in the fridge for at least an hour. When firm I rolled them out and stacked the flattened dough. I rolled it up like a jelly roll and then sliced it. They baked out HUGE! It looked like one big cookie. So I took my biscuit cutter and cut out cookies while they were still warm.
