If you are thinking to try a cookie recipe then how about making these amazing swirled cookies?
To make these first you have to make sugar cookie dough. Divide it in half and add blue gel food color to one part. Roll both the parts flat and layer them over each other. Then roll them and brush a bit of water on the dough log. Cut the two sides to get neat edges. Spread nonpareil sprinkles on a flat surface and roll the dough log over them. Wrap the sprinkle covered log in a cling film and refrigerate for about an hour. When chilled take it out of the fridge and unwrap it. Slice the log and put the cookies on a baking tray. Bake them until done.
These are going to be a guaranteed hit. Happy baking!
