What Is a Vanilla Slice?
A vanilla slice is a dessert made from layers of puff pastry filled with a thick, set vanilla custard and usually topped with either icing sugar, a simple glaze, or passionfruit icing. Known for its neat, square appearance and firm structure, the vanilla slice is best enjoyed chilled. It is often served in bakeries, cafés, and home kitchens, especially in Australia where it has developed a loyal following.
The dessert is sometimes compared to the French mille-feuille or Napoleon, but with distinct differences, especially in flavor and texture. While mille-feuille typically has whipped cream or lighter fillings, the vanilla slice features a sturdier custard, allowing it to be sliced cleanly and held without collapsing.
Key Components of a Vanilla Slice
There are a few essential elements that define a proper vanilla slice:
- Puff Pastry: Light, flaky pastry is baked separately until golden brown and used as the top and bottom layers.
- Vanilla Custard: A thick custard, often made with milk, eggs, cornflour, sugar, and vanilla extract, forms the core filling.
- Topping: Typically a layer of icing, which may be plain, lemon-flavored, or passionfruit-infused. Some versions are dusted with powdered sugar instead.
Origin and Cultural Significance
The exact origins of the vanilla slice are difficult to trace, but it’s widely believed to be inspired by European pastries such as the mille-feuille. Over time, Australia and New Zealand adapted and popularized the dessert in their own unique ways, developing what is now seen as a distinct regional version.
In Australia, the vanilla slice has taken on a life of its own. It is commonly referred to as snot block in slang a humorous nickname that refers to its wobbly custard center. Despite the cheeky moniker, it remains a source of great affection and pride.
