Double Stuf is not even close. Yes I understand they put in double the creme of the “normal cookie” but it still doesn’t hit the mark.
This could work in many situations but sometimes you still want a bit more stuf in between your cookie sandwich. Sometimes you have to say more stuf is needed. 
Okay this is a bit too much stuf or is it? One bite is all it will take if only I had a mouth big enough to stuf it in.
