About
A vanilla slice is two sheets of puff pastry with a firm vanilla custard thick enough to stand, iced with passionfruit or plain fondant. Bakery ones use a gelatine-set custard so the slice survives the bain-marie of a display fridge. This home version does too. It should be cold, neat, and slightly ridiculous to eat. An Australian bakery vanilla slice is two rectangles of baked puff pastry with a slab of vanilla custard thick enough to cut into squares, iced with fondant or passionfruit icing. It is not a French mille-feuille, which is usually lighter, often three sheets, and less of a custard brick. Bakery cabinets use gelatine or a heavy cornflour set so the slice survives a cold display. Chill hard. Cut with a hot wet knife. Passionfruit icing is one state religion; plain white or pink fondant is another.

History & culture
Every bakery has one. Victoria and New South Wales argue about icing. 'Snot block' is a loving insult. Every suburban bakery has one. 'Snot block' is Australian slang, affectionate and accurate when the custard squishes. People will drive for a particular shop's icing. New Zealand's custard square is a close cousin, not always the same icing. Eat it cold, from a paper bag, over a bin or a plate. It is a slice, not a plated dessert with coulis.
A cousin of the mille-feuille that Australia made rectangular and custard-heavy. A rectangular, custard-heavy Australian take on European puff-and-cream pastries, standardised by twentieth-century bakeries rather than by a single inventor. Mille-feuille is the French cousin; this is the cabinet slab. You are sandwiching set vanilla custard between puff and icing it. That is a vanilla slice. Do not sell it as Paris pastry.
