This idea looks so good you wouldn't want to eat it. But oh well, it's too good to waste! Start by getting vanilla ice cream and another flavour. (I think Ben and Jerry's choc chip cookie dough or haagen diaz cookies and cream is really good) and place a scoop of each in a sundae glass. Next put crushed up oreos, choc. chip cookies or gingernut biscuits in and some more ice cream. Then some, choc sauce, ice cream, rolos, ice cream, toffee sauce then 3 scoops of ice cream, sauces and another rolo! Viola, you have 1 chocolate cookie toffee sundae. This is only a guide so you could put any ice creams, biscuits, sweets or sauces on. How about a strawberry crunch sundae!?
