This delightful Tan Slice recipe is a classic Kiwi treat featuring a buttery biscuit base topped with a luscious caramel filling, all finished off with a layer of rich chocolate and shortbread crumble.
Preheat the oven to 180ºC/350F and line a baking tin with greaseproof paper.
Place the flour, butter salt and vanilla extract into a bowl and beat on low until the mixture looks like a rough crumble and no piece of butter is larger than a pea.
Press a portion of the mixture together in the palm of your hand, it should hold with only a few crumbs falling away.
Set aside ⅓ of the mixture and pour the remainder into your tin, pressing down firmly until even.
Place in the oven and bake for 12 minutes or until ever so slightly golden.
Caramel filling
Meanwhile, place the sweetened condensed milk, butter and golden syrup in a saucepan over low heat.
Stirring constantly until the mixture has thickened to a light custard texture, approximately 5 minutes.
Pour the caramel over the shortbread dough and spread out evenly.
Toss the chocolate chunks into the remaining crumble and stir to combine
Scatter over the caramel unevenly, leaving some pockets of caramel visible.
Bake in the oven for 20 minutes or until golden on top.
Remove and allow to cool for at least 3 hours or preferably overnight.
Slice into bars.
Serve up and dig in.
Enjoy!

Notes
Sweetened condensed milk: Full fat sweetened condensed milk is essential here because it will set perfect during baking.
Golden syrup: The essential syrup needed to make these the traditional way, you could substitute with honey, agave syrup or brown rice syrup, if you prefer though.
Chocolate: 56% dark chocolate was used here, though milk would work also. The best option is to use a chocolate bar over baking chocolate thanks to a high quality. You could replace in equal measure with chocolate chips.
Baking tin: A 18x18 cm or 7x7 inch square baking tin works well here, though a rectangle tin would also work well. Note, the larger the tin from the one used here, the thinner your base and caramel will be.
Make ahead: It can be prepared in advance and stored in an airtight container in the refrigerator for up to 5 days.
