Chocolate Peppermint Slice

This is one of my favourite slice recipes, chocolate and mint has to be one of the best combinations! It’s the perfect level of sweetness and pepeprmint flavour.

The slice is simple and easy to make. The base is baked in the oven and the while still hot topped with the creamy peppermint filling. The chocolate is drizzled over and left to set before slicing up and enjoying!

NZ Peppermint Slice

Mint Slice, Choc-Peppermint Slice or just simply Peppermint Slice, whichever name you have for it, is another classic New Zealand slice. An oldie but a goodie, you probably remember eating it when you were younger. It can be found in nearly every bakery or supermarket and it’s one of my favourites!

If you’re a fan of Arnott’s Mint Slice biscuits (this is honestly the best biscuit ever) this slice tastes basically identical!

Tips and Tricks

• Don’t over bake the base – The base only needs about 20-25 mins in the oven. It’ll still be soft when it comes out but will harden as it cools. You don’t need to bake the base until it feels firm.
• The peppermint filling should be thick – You might want to add more liquid to the peppermint filling but it doesn’t need it. It should be thick as it will hold its shape.
• Add some green food colouring – If you like a little colour add a drop of green gel food colouring to the peppermint filling.
• Add the filling while the base is still hot – Adding the filling to the base while its hot will soften the filling making it so much easier to spread it evenly.
• Cut the Peppermint Slice when its cold – This is the easiest way to get clean cuts. Make sure you’re using a hot sharp knife and clean it down in between cuts.

How to Make Peppermint Slice

Preheat oven to 180C / 350F.

In a medium sized bowl or the bowl of your stand mixer add the butter and sugar. Cream together for 3-4 minutes or until light and fluffy.

Add the dry ingredients to the bowl with the creamed butter and sugar, the flour, cocoa powder, desiccated coconut and baking powder.

Fold the dry ingredients into the creamed butter and sugar until well combined.

Use a spoon to press the base evenly into a lined 20cm or 8″ square baking pan.

Bake in the oven for 20-25 minutes or until slightly browned.

While the base is baking in the oven make the peppermint filling. Add the sugar, butter, milk and peppermint essence to amedium sized mixing bowl

Fold together until well combined with a wooden spoon. It should be pretty thick.

While the base is still hot from the oven add the peppermint filling on top.

Use an offset spatula to spread the filling into an even layer, getting right into the corners. Leave to cool for 30-60 minutes before making the topping.

Once the base and filling has cooled make the chocolate topping.

Break or cut the chocolate up into small pieces and add to a heat proof bowl.

Pour the oil on top and melt the chocolate either in the microwave in 20 second bursts until smooth or over a water bath.

Pour the melted chocolate over the cooled peppermint filling and tilt the pan to cover the edges.

Transfer to the fridge for 2-3 hours or overnight until completely set.

How to get clean slices

Remove the peppermint slice from the fridge and pull it out of the baking pan by use the paper on the sides.

Use a hot sharpe knife to get clean even slices, cleaning the knife off in between. You can cut it into 16 or 12 pieces depending on the size you would like.

Storing the Peppermint Slice

Store the peppermint slice in an airtight container in the fridge for up to 2 weeks.
