Vanilla Slice
Ingredients
- 2 purchased sheets of read made puff pastry
- 250ml (1 cup) milk
- 1 vanilla bean, split ( I used vanilla essence instead) *note - 2tsp of essence is equivalent to one vanilla bean*
- 3/4 cup cornflour
- 1/2 cup custard powder
- 220g (1 cup) caster sugar
- 750ml (3 cups) thickened cream
- 50g unsalted butter
- 3 egg yolks
- Icing sugar, to dust
Instructions
- Step 1
- Preheat oven to 210C. Line a 23cm square pan with aluminium foil, so that the foil comes up over the sides (this allows you to lift out the slice).
- Step 2
- Place each pastry sheet on a baking tray lined with non-stick baking paper, then bake for 8-10 minutes or until golden brown. Set aside to cool.
- Once cool, place 1 pastry sheet, cooked-side up, in bottom of pan. (You may need to trim it slightly to fit.)
- Step 3
- Set slow cooker on high, I used a small one 2.4L
- Put the cornflour, sugar and custard powder in the slow cooker, and put the milk and vanilla mixture in and whisk until smooth,
- Then add cream, mix well.
- Place lid on slow cooker and let it cook for about 1 hour or until it thickens, stirring couple times in between.
- Add butter, stirring well to combine, then remove from heat and whisk in egg yolks, one at a time, until smooth.
- Step 4
- Pour into pastry-lined pan and set aside to cool slightly before placing other piece of pastry, cooked-side up, on top. Refrigerate overnight.
- Remove from pan, cut into squares and dust with icing sugar.

Better than from the Bakery
A really lovely recipe.
Note to self – Make double 🙂
Looks great
Wow!!! Absolutely amazing!! First time cooking this and turned out fabulous!!
I made this the other night in my Russell and Hobbs 6L. It took nearly 2 hours to thicken which was incredibly frustrating but aside from that it was so easy to make and so worth it. Hubby took it to work and had at least three individuals approach him independently to say it was the best vanilla slice they have ever had!
Cook for one hour … on low or high heat??
Has anyone tried with short crust pastry instead of puff?
What is thickened cream ?
What is thickened cream? Or is there a different kind of cream I can use?
It’s a pouring cream in Australia
This is THE BEST vanilla slice EVER!! I’m having to make double batches now as it gets devoured so quickly
Have made this twice now. Delicious!! Kids love it.When cooking the pastry I put baking paper top and bottom and placed another tray on top to stop it rising. Have added this to my to keep recipes.
YUM!!
Does this recipe fit 1.5 ltr slow cooker??
What is thickened cream??
In Australia it’s our regular pouring type cream
Pauline whar is butterfat content of thickening cream maybe we can figure out from that no such product in canada
But we have coffee and whipping cream
for those asking what thickened cream is its also known as double cream, Recipe looks awesome will have to give it a try
What can be used to substitute the egg yolks?
OMG Nancy this recipe is amazing!!! Best vanilla slice I’ve ever made ?? I topped this with sc vanilla icing and was just like the bakery version ? thanks so much for sharing this with us xxx
Thickened cream is minimum 35% fat, and has gelatin added to make it thicker. It’s not like double cream or “pure” cream that has a much higher fat content.
Thickened cream… so whatever cream you use in your country to beat with a fork or beater to make thicker to put on scones or sponge cakes etc
Hi! Do you need to let the mix cool down before whisking in the egg yolks?
Hi, if the slow cooker is bigger will it take longer??thanks
My mixture doesn’t seem to be thickening? Anyone else had this?
Just want to know it says to whisk in egg yolks when still hot is this right thought it would scramble them pls help
Can you use saos instead of the puff pastry ?
Absolutely delicious! Just under 1 hour to cook the custard in my 7litre Slow Cooker. It went a little clumpy as I added some extra custard powder after the cream, it didn’t matter in taste ?
I made it the traditional way by actually making up the icing (mix icing and boiling water in bowl, pour paste over slice THEN refrigerate) – it didn’t seem right to just dust it.
10/10 recipe. Will make this next time I have guests ??
Was absolutely amazed with how well this recipe turned out., it’s always been a favourite in our household. If you haven’t tried it definitely give it a go you won’t regret it
So easy to make and so delicious. I used a larger tray so the slices aren’t as high and cut them into smaller portions. Family loved them.
If I’m making this in a 7lt rectangular slow cooker I would need double the mix…correct???
