This is a treat that is always great for a birthday.First you get any type of cookie (we usaully just use chocolate chip)and put in a round pan then bake it.When it is done, you dercorate with icing and other toppings and if you want to you can cover the whole cookie like it was a real cake. You can decorate before the guests arrive or you can decorate together when everybody gets there (i think decorating it with everdoy is better).Then when you are done you can eat right then or wrap with saran wrap and put in the fridge for later.
