Classic vanilla slice

Classic vanilla slice


  • 2 sheets of puff pastry 
  • 220g sugar
  • 90g cornflour
  • 50g custard powder
  • 700ml milk
  • 300ml thickened cream
  • 60g butter
  • 2 tsp vanilla extract
  • 3 egg yolks
  • icing sugar (optional)


  1. Preheat the oven to 190 degrees celsius, place your puff pastry sheets onto baking trays lined with baking paper, place another sheet of baking paper on each puff pastry then place another baking tray on top of that, this prevents the pastry from rising. once the oven is heated, place the puff pastry in the oven and bake for 25 minutes or until golden brown, allow to cool completely before removing off the tray.
  2. Prepare a tin that will fit your puff pastry with baking paper, ensure that the baking paper goes all the way up the walls of the tin to make it easy to remove the slice once it's set.
  3. Combine sugar, cornflour and custard powder in a saucepan. Gradually add the milk and whisk until smooth. once smooth add the cream and stir over medium heat until mixture starts to boil and thicken. Allow to boil, stirring constantly for 1 minute. Reduce heat to low, add butter and vanilla extract and whisk until butter is melted. When the mixture is smooth, remove the pan from heat, then whisk in egg yolks one at a time until combined.
  4. Add one sheet of puff pastry into your prepared tin, pour your custard onto and then place the second sheet of puff pastry, allow to set in the fridge overnight before cutting and dusting with icing sugar.
