Traditional Vanilla Slice - The original snot block!

How to Make a Traditional Vanilla Slice

Traditional Vanilla Slice is a combination of delicious homemade custard, flaky puff pastry and icing.  Yummy yum yum.  If you want the ‘cheating version’ with vanilla pudding mix – we have that too!

I used to buy a ‘Snot Block’ every day on the way to school. It was an addiction.  Traditional Vanilla Slice is totally Australian and totally delicious!

A little hint to get the very yummiest Traditional Vanilla Slice out there – get the Extra Buttery Puff Pastry – it will be in the freezer section of your local supermarket.  Yes it is extra naughty – but extra delicious!

How to Make Vanilla Slice:

  1. Preheat oven to 190 degrees.
  2. Line two oven trays with baking paper.
  3. Place the pastry sheets on the prepared trays and prick all over with a fork.
  4. Bake for 10 - 15 minutes or until golden and crisp.
  5. Cool on a wire rack.
  6. To make the custard, blend the custard powder, sugar, milk and cream in a saucepan over medium heat until custard boils and thickens.
  7. Remove from heat and stir in vanilla.
  8. Cover the surface of the custard completely with plastic wrap (to stop a skin forming) and cool completely.
  9. Spread one sheet of the puff pastry evenly with custard. Top with remaining pastry sheet upside down.

  11. Stand the bowl over a pan of simmering water and stir until the icing is smooth and glossy.
