What Is a Vanilla Slice in Australia?

A vanilla slice is a sweet, gooey dessert that’s typically made with shortbread pastry and custard. It can be flavored with either vanilla or chocolate and iced with either vanilla, chocolate, strawberry, raspberry, or passion fruit icing.

the vanilla slice is often cut into pieces and iced with sugar to add a bit of crunch to the treat. It usually comes in bakeries or cafes in Australia, but can also be referred to as a ‘snot block’ due to its creamy consistency.

The Australian interpretation of the vanilla slice has been described as a uniquely Australian food, but it may have actually come from France and originally resembled the French mille-feuille.

Every year the Great Australian Vanilla Slice Triumph competition is held to determine who the best vanilla slice baker is. Judging criteria include “when tasted, should reveal a custard with a creamy smooth texture and a balance of vanilla taste with a crisp, crunchy pastry topped with a smooth and shiny glaze/fondant”.

  • 2 tsp vanilla extract
  •  cup (150g) caster sugar 
  •  cup (50g) cornflour
  • ½ cup (125ml) water
  • 6 egg yolks 
  • icing (confectioner’s) sugar, for dusting


  1. Preheat oven to 180ºC (350ºF).
  2. To assemble the pastry, place pre-rolled sheets on a non-stick baking tray lined with parchment paper. Top each sheet of pastry with more parchment and an additional baking tray to keep the thickness together.
  3. Bake for 20-25 minutes or until golden. Cool on wire racks completely and trim the pastry to 22cm squares.
  4. Place the milk, cream, butter, sugar, and vanilla in a medium saucepan over medium heat. Once it reaches just below boiling point, remove it from heat.
  5. Mix cornflour and water with the hot milk mixture, then whisk in egg yolks. Bring to the boil while stirring constantly for 30 seconds-1 minute or until thickened.
  6. Place one sheet of cooked pastry at the bottom of a lightly greased cake tin. Place the custard and remaining piece of pastry on top and press down gently.
  7. Refrigerate for 3–4 hours or until set. Dust with icing sugar and slice to serve.

Vanilla Slice with Vanilla Bean Praline Recipe



  • 2¼ cups (560ml) milk
  • 2¼ cups (560ml) single (pouring) cream
  • 90g unsalted butter, chopped
  • 1½ cups (330g) caster (superfine) sugar
  • 2 vanilla beans, split and seeds scraped
  • ⅔ cup (100g) cornflour (cornstarch)
  • ¾ cup (180ml) water
  • 9 egg yolks

Rough Puff Pastry

  • 3 cups (450g) plain (all-purpose) flour, plus extra for dusting
  • 450g chilled unsalted butter, chopped into 2cm pieces
  • 1 cup (250ml) iced water

Vanilla Bean Praline

  • ½ cup (110g) caster (superfine) sugar
  • ¼ cup (60ml) water
  • 1 vanilla bean, split and seeds scraped


Making the Rough Puff Pastry

  1. Place the flour and butter in a large bowl. Using your fingertips, rub the butter into the flour until roughly combined (the butter should still be lumpy, about 1cm pieces). Make a well in the center, add the water, and mix, using a butter knife, into a dough.
  2. Turn out onto a lightly floured surface. Roll the dough out to a 20cm x 50cm rectangle (there will still be lumps of butter in the pastry).
  3. Starting at the top short edge, fold the pastry down to the middle, and fold the bottom up to overlap the top. Turn the pastry a quarter turn, and roll out again to a 20cm x 50cm rectangle.
  4. Repeat the folding process 5 more times. Wrap in plastic wrap and refrigerate for 1 hour to firm. 
  5. Preheat oven to 200°C (400°F). Line 2 baking trays with non-stick baking paper. Halve the pastry and roll out, on a lightly floured surface, to make 2 x 30cm x 40cm rectangles.
  6. Place on the trays and bake for 30–35 minutes or until golden brown and puffed. Allow cooling completely.
  7. Line a 20cm x 30cm slice tin with non-stick baking paper, leaving 4cm paper over the rim. Trim each pastry sheet into a 20cm x 30cm rectangle and use 1 to line the base of the tin.

Making the Filling

  1. Place the milk, cream, butter, sugar and vanilla bean, and seeds in a medium saucepan over medium heat. Bring to just below the boil. Remove from the heat and discard the vanilla pods.
  2. Place the cornflour and water in a small bowl and mix to combine. Add the cornflour mixture and egg yolks to the milk mixture, return to the heat and whisk for 30 seconds or until thickened.
  3. Pour the mixture into the tin, smooth into an even layer and top with the second sheet of pastry.
  4. Refrigerate for 4 hours or until completely cold and set.

Making the Vanilla Bean Praline

  1. Line a small baking tray with non-stick baking paper. Place the sugar and water in a small saucepan over low heat and cook for 4–5 minutes or until the sugar is dissolved. Increase the heat to high and cook, without stirring, for 8–9 minutes or until dark golden brown.
  2. Remove from the heat, add the vanilla seeds and stir to combine. Carefully pour onto the tray and allow to cool completely.
  3. Once the praline is set, break it into pieces and place in a mortar. Pound with a pestle until fine.


  1. Cut the slice into lengths, place onto serving plates and sprinkle with the vanilla bean praline to serve. 
  2. Serves 8–10

A Bavarian Slice is a more indulgent and posh version of the custard slice. The filling is creamier, it has icing for decoration, and the icing often has a feathering pattern.

How long does vanilla slice last for?

The vanilla slice is best eaten on the day it’s made and can be stored in an airtight container in the fridge for up to 2 days.

Can I freeze the vanilla slice?

To freeze an entire slice, first wrap in a layer of plastic wrap and then in a layer of foil. Place into an airtight container in the freezer – this 3 step process will keep your slices tasting amazing once defrosted.
