Vanilla slice is a type of cake. It consists of a thick custard sauce, which is traditionally flavoured with vanilla, and which is sandwiched between flakey puff pastry or filo pastry and iced with either vanilla, raspberry or passionfruit icing.

It is commonly sold in milk bars and cake shops in Australia and is often referred to as a 'Snot Block' due to the consistency of the custard.

They are also popular in the north of England.

It is probably a version of the 'Napoleon' which may have originated in France or Italy, though the filling is not always custard, and can be savoury (such as spinach and cheese). Another variation popular in England is the Bavarian Slice which has a layer of raspberry or strawberry jam and rippled icing.
