Worlds Largest Cookie Ice Cream Sandwich

We reached 4 million subscribers and we celebrated with a the World s Largest Cookie Ice Cream it was more of a frozen yogurt sandwich and it was VERY MESSY, but quite good We used chocolate, vanilla and cookies n cream frozen yogurt and put it between the chocolate chip cookies. We had planned to do 4 cookies thick, but the ice cream was melting so fast we could only use two :)
