If you’re American, the word slice probably makes you think of pizza.
If you’re a Kiwi, slice means something entirely different.
A New Zealand slice is a beloved category of baking: usually something made in a shallow tin, cut into squares or rectangles and served as a sweet treat. It might have a biscuit base, layers of caramel, jam, chocolate, coconut, icing or meringue. Some are crisp, some chewy, some gooey and some wonderfully buttery.
And there are a lot of them.
Ginger Crunch. Lemon Slice. Caramel Slice. Louise Cake. Afghan Slice. Tan Square. Hedgehog...
They're the sort of things you'll find at morning tea, school bake sales, community fundraisers, cafés and in the baking tins of Kiwi mums and grandmothers.
Slices are everyday New Zealand baking. They're unfussy, generous and made to be shared.
The history, as best we can establish it
The slice is part of the broader Anglo-Australasian home-baking tradition. In the US, many of these things would fall under bars, squares or bar cookies. In New Zealand and Australia, they gradually became known as slices.
The exact origin is difficult to pin down, because slices weren't invented by one famous pastry chef. They grew out of home kitchens and community baking, where recipes were passed around, adapted and written into the community cookbooks that became such an important part of New Zealand food culture.
This was practical baking. A single tin could make enough treats for a family, a school fundraiser, a church gathering or a Sunday afternoon with visitors. And the ingredients were the things most people already had in the pantry: butter, flour, sugar, coconut, oats, golden syrup, cocoa, jam.
Over time, those simple pantry ingredients produced an extraordinary collection of slices that became distinctly Kiwi.
And then there is Ginger Crunch. The queen of slices.

What makes Ginger Crunch different?
Ginger Crunch isn't simply a ginger-flavoured cookie or a gingerbread bar. It has two completely different textures working together.
First, there's the crisp, buttery biscuit base. Then comes the thick ginger topping, made with butter, sugar and plenty of ginger.
The base crunches. The topping is soft and almost fudgy. You get butter, sweetness and that warm hit of ginger all at once.
And that contrast is the magic.
