National Dish New Zealand: Custard Square (Recipe)
In this article
Meet the Custard Square, the sweet treat that sits behind the glass of practically every bakery in New Zealand! Crisp sheets of puff pastry sandwich a thick, golden layer of vanilla custard, all finished with a glossy sheet of icing. It is unashamedly nostalgic, wonderfully simple and far easier to make at home than its neat bakery edges suggest. Once you have cut your first square, you will understand why Kiwis are so fiercely loyal to it.
About Custard Square
The Custard Square is a genuine highlight among New Zealand’s sweet bakes. It brings together delicate puff pastry, a rich layer of vanilla custard and a sweet icing top. The dessert first found its home in the country’s traditional bakeries and remains hugely popular to this day. Whether at a celebration or simply as an afternoon snack with a cuppa, the custard square has earned a special place in Kiwi hearts.
Ingredients (serves 1–2)
- 250 g puff pastry
- 200 ml milk
- 2 eggs
- 50 g sugar
- 40 g cornflour
- 1 teaspoon vanilla extract
- 100 g icing sugar (for the topping)
- 1–2 tablespoons water (for the topping)
Shopping for the ingredients
When shopping for the custard square, most of what you need is available in any ordinary supermarket. It is particularly important to choose good-quality puff pastry, as it forms the base of the entire dessert. Fresh ingredients such as milk and eggs are best bought organic or free-range for the finest flavour. The vanilla extract plays a decisive role too, so look for a proper extract rather than a synthetic essence.
Preparing the dish
Preparing the custard square calls for a little patience, but it is well worth it. Start by rolling out the puff pastry and trimming it to the size you want. While that is done, you can make the vanilla custard by combining the ingredients in a pan and heating them gently. This mix of groundwork and simultaneous cooking is what gives you a flawless result at the end.
Step-by-step instructions
- Preheat the oven to 180 degrees Celsius.
- Roll out the puff pastry and lay it into a square tin.
- Heat the milk in a pan, but do not let it come to the boil.
- In a bowl, whisk together the eggs, sugar, cornflour and vanilla extract.
- Slowly pour the warm milk into the egg mixture, stirring well.
- Return the mixture to the pan and heat, stirring constantly, until the custard thickens.
- Pour the hot custard over the pastry and smooth the surface.
- Carefully lay the second sheet of pastry on top and bake for about 20 minutes.
- Once cooled, spread over an icing made from icing sugar and water.
Gluten-free / lactose-free version
To make the custard square gluten-free, simply swap the usual puff pastry for a gluten-free one. Lactose-free milk and plant-based alternatives such as almond or oat milk are an equally good choice for anyone who is lactose intolerant. Do check the remaining ingredients and how they behave together so you still get the result you are after. The finished bake will be every bit as delicious and satisfying — much like a gluten-free take on Ginger Crunch.
Tips for vegans and vegetarians
For a vegan version of the custard square, the eggs can be replaced with plant-based alternatives such as chia or flax seeds. Reach for a plant milk as well to make the dish entirely vegan. The remaining ingredients are generally already suitable for vegetarians. That way vegans can enjoy this labour of love too, without compromising on flavour or pleasure.
More tips and tricks
A few small tips will improve your custard square no end. Keep the puff pastry well chilled before you roll it, so it does not turn sticky. For the topping you can also use natural sweeteners such as honey or maple syrup to shift the flavour. And do not be afraid to experiment with different flavourings to tailor the dessert to your own preferences.
Adapting the recipe to your taste
The scope for adapting the custard square is close to limitless. Fold fresh berries or chocolate chips into the vanilla custard, for instance, for a fruity or chocolatey twist. Building in different flavours, such as chocolate or lime, is another way to personalise it — the same trick that works so nicely with a Lemon Honey Tart. This way you can keep trying new variations and turn the dessert into a genuine household favourite.
Ingredient substitutions
If you are looking for alternatives to specific ingredients, there are plenty of options. Instead of sugar you might use coconut sugar or erythritol to bring down the sugar content. Likewise, in place of the traditional vanilla extract you can try other flavourings such as almond or caramel. Small adjustments like these can make a big difference to the taste and are well worth exploring.
Drink pairing ideas
To accompany the custard square perfectly, a few well-chosen drinks are worth considering. A freshly brewed coffee or a strong pot of tea works beautifully to balance the sweetness of the dessert. Alternatively, try a creamy milkshake, which plays up the richness of the custard. This approach rounds out the whole experience and makes the treat even more enjoyable.
Serving and presentation ideas
Presentation matters a great deal when it comes to serving the custard square well. Surprise your guests by arranging the slices on a handsome plate and decorating them with fresh fruit. A light dusting of icing sugar across the top lends an elegant finish. Details like these make all the difference and help your creation look even more irresistible — try it alongside a Pavlova on a dessert table.
