Ingredients

Slice
  1. 2 sheets frozen puff pastry
  2. 1 cup + 2 tbsp (250g) caster sugar
  3. 1/3 cup + ¼ cup (90g) corn flour
  4. ½ cup (60g) custard powder
  5. 3 cups (750ml) milk
  6. 1 cup (250ml) cream
  7. 60g butter
  8. 2 tsp Queen Organic Vanilla Bean Paste
  9. 3 egg yolks
Icing
  1. 1 ½ cups (225g) pure icing sugar, sifted
  2. 2 tbsp (40ml) milk
  3. 1 tsp Queen Natural Vanilla Extract

Method - Vanilla Slice

  1. Step 1

    Preheat oven to 180°C (fan forced) and defrost puff pastry sheets. Line two baking trays with baking paper and lay the pastry sheets on top, then place another baking tray on top to prevent pastry rising too much during baking. Bake for approximately 20 minutes, or until the pastry is golden. Remove from oven and allow to cool completely.

  2. Step 2

    Line a 23cm square tin with aluminium foil, extending it over the sides so you can use it as handles to remove the slice when cool. Place one sheet of pastry in base of tin, top side down.

  3. Step 3

    Combine sugar, corn flour and custard powder in a saucepan, then gradually add half the milk and whisk until smooth. Add the rest of the milk, and cream and stir over medium heat until mixture boils and thickens. Reduce heat to low, add butter and Vanilla Bean Paste and whisk until butter is melted and mixture is smooth. Remove pan from heat, then whisk in egg yolks until combined.

  4. Step 4

    Spread vanilla custard over pastry in tin, then place the second pastry on top (top side down) and allow to cool.

Method - Vanilla Icing

  1. Step 1

    Combine icing sugar, Vanilla Extract and milk, mixing until smooth the spread over the top of pastry. Cut Vanilla Slice into 16 portions and serve.

Tips:

To ensure your vanilla slice sets properly, be sure to boil the custard for at least a minute, stirring constantly. Set in the fridge for at least 6 hours (preferably overnight) before slicing.

Comments & Reviews

I tried your vinilla slice recipe and followed it precisely but the custard failed miserably. After overnight in refrigerator it was exactly the same as it came of the stove

Tom

Hi Tom, oh no – we’re so sorry to hear your slice didn’t set! This usually happens when the custard isn’t heated to a high enough temperature for long enough. It should get to a point on the stove where it’s almost too thick to stir. Hopefully you’ll give this recipe another go, but in the meantime enjoy your vanilla custard with some fresh fruit! – The Queen Team

Thank you very much for this recipe…First attempt turnout very good 5stars..

Ruth

Can you freeze them after baking?

Mary

Hi Mary Anne, unfortunately this recipe does not freeze well as the texture of the custard will split and change once thawed.

Nice recipes

Judy

What cream do you use please? x

Stacey

Hi Stacey, pure or thickened cream works perfectly for this recipe!

Queen Fine Foods

Even though I had to replaced the milk and cream with long life milk, the custard slices have now become our favourite recipe. We replaced the puff pastry with cream cracker biscuits which makes it easier to serve.

I did this exactly and custard is just runny everywhere this morning i don’t know what happened

Tiffany

Hi Tiffany, so sorry to hear your custard didn’t set! Sometimes this can happen if the mixture isn’t boiled for long enough (step 3). This can be a bit scary as you don’t want it to burn – the trick is to keep stirring! Hopefully you’ll give this recipe another try, and in the meantime enjoy your delicious vanilla custard with a slice of cake or some poached fruit 🙂 Happy baking – The Queen Team.
