My banoffi pie is so good, it's (almost) famous!...it has even inspired marriage proposals!...all denied thus far. :p To make simply boil a can of condensed milk for 1 1/2 hours (ignore the warning on the can that tells you not to do this! :P). To make the base, pop 12 digestive biccies in a sandwich bag and crush using a rolling pin. Then combine with 4oz of butter. Smooth onto a tin. Layer the toffee on the base, followed by a neat layer of banana slices, whipped cream and choc shavings. Yum!
