Vanilla slice is the Australian answer to mille-feuille - this dessert consists of a thick custard that’s flavored with vanilla, sandwiched between puff or phyllo pastry sheets, and topped with vanilla, raspberry, strawberry, chocolate, or passion fruit icing.
Due to the fact that the texture of the custard is slightly wobbly, the vanilla slice is sometimes also called a snot block. Once prepared, the dessert is cut into slices before being served. This dessert is so popular that there is an annual competition for the best vanilla slice baker, called the Great Australian Vanilla Slice Triumph.
