Vanilla slice ice cream

Sharing is caring!

A delicious ice cream twist on a classic Aussie dessert.

Vanilla slice, custard square, call it what you like this classic Aussie dessert is full of nostalgia and childhood memories for many Australian's and Kiwi's alike

Vanilla slice competitions are hotly contested up and down the country. Some prefer classic style with its bright yellow custard and pink icing on top, while others prefer the french style, with a creamier custard and passionfruit icing.

Its hard to think how you could improve on such a thing. And then I added ice cream. This is not the shortest recipe, but its not hard and well worth the effort. If you like vanilla slice you're going to love this 🙂

Make your custard base first. This will need to freeze overnight so its nice and firm. This is not a recipe you can serve straight from the ice cream churner, it needs time to set.

You can either make the pastry and icing the same day as the ice cream and assemble the following day, or do the pastry and icing the following day. Make sure you give your pastry enough time to cool. Hot pastry and custard ice cream equals soggy vanilla slice ice cream!

To make the custard ice cream add the custard powder, tapioca flour, sugar and milk to a medium sized pan. Whisk together and heat over a low heat.

Whisk whisk whisk until mixture becomes very thick, about 15 mins. You may need to use a spoon or heat proof spatular to get into the sides of the pan where the whisk can't reach. Keep whisking, you want a nice smooth custard. This is not the thing to be doing when your arms are sore after a new gym session the day before hand, just sayin! If its taking a long time you can turn up the heat but you will need to watch it like a hawk and whisk whisk whisk to prevent lumps. You also need to cook the base long enough to cook out the 'floury' taste of the custard powder and tapioca flour so don't rush it to much.

Allow custard to cool, then add cream and vanilla essence. Mix or whisk together until smooth. Chill mix until cold.

Hot tip: If you are having trouble getting the lumps out pass the custard base through a sieve. Don't be tempted to use a hand mixed as you will knock all the thickness out of the custard.

Prepare your deep sided dish by lining with freezable cling wrap or similar, leaving a wide edge to help you remove the ice cream later. You may need to criss cross the cling wrap to get to fully cover the bottom.

If you are using a self refrigerating ice cream churner turn it on about ten minutes before churning. Other wise take your bowl out of the freezer immediately before churning. Churn the custard base. It will be the consistency of soft serve when done, about 25 mins.

Hot tip: Make sure there is space in your freezer to put your deep dish in flat and stable Before you put your ice cream in it, or there will be tears!

Put churned ice cream into lined deep dish and flatten out as best you can. Put another layer of freezable cling wrap over the top. Freeze overnight. You need the ice cream to be nice and firm to assemble the vanilla slice ice cream.

To make the pastry heat your oven to 420°F (220°C). Defrost two sheets of store brought butter puff pastry. I used Pampas butter puff and they are 9" (23cm) squared . You can make your own pastry if you want, such as the one here, but I wanted to concentrate on the ice cream for this recipe.

You will need two sets of trays that fit nicely over each other. If you only have two suitable trays you can do the pastry in batches. Line the trays with baking paper and put on pastry.

Hot tip: Remember to remove the plastic backing from the pastry sheets before putting them on the trays.

Prick each sheet of pastry all over with a fork. This will help stop the pastry from bubbling up. Put on another layer of baking paper and your second tray on top. Bake in the oven until golden, approx. 15 mins.

Remove from oven and allow pastry to cool completely. Score the pastry lightly then cut through, this will help stop the pastry from cracking. Cut pastry into eight pieces as shown, or smaller for smaller slices. If not assembling until the following day place in an airtight container until needed.

Hot tip: A pizza cutter works well for cutting the pastry.

To make passionfruit icing sift icing thoroughly. Do not skip this step as you will end up with lumpy icing that's hard to mix. Add passionfruit pulp and mix until smooth. If you don't like passionfruit seeds you can strain them out, but you will need more passionfruit pulp to reach the right consistency. Add more passionfruit pulp if you want thinner icing.

To assemble the Vanilla Slice ice cream, ice half your pastry squares with passionfruit icing. Remove the custard ice cream from the freezer and remove from dish using cling wrap overhang. Run a large knife under hot water and dry quickly. Cut the ice cream eight rectangles or the same size pieces as your pastry, re-heating and drying the knife as needed.

Place one non iced pastry piece in the bottom. Top with one piece of custard ice cream. Top with one piece of iced pastry. You can put a few dots of passionfruit pulp on top if you wish.

Eat and enjoy!
