all ingredients for peppermint slice, laid out on a table.

Sweet biscuits – plain, sweet store-bought biscuits are best! If you’re in Australia, I recommend using Arnott’s Marie or Arrowroot biscuits, or Digestives. In other areas like the US, Graham crackers or any other plain, sweet cookie will work.
Peppermint Crisp – a South African chocolate bar that can be found in most Australian supermarkets. It has a brittle, crystalline/sugar peppermint flavoured centre that is coated in milk chocolate. If you can’t source Peppermint Crisp chocolate, you can use any other type of peppermint candy bars, like Aero, blocks of Cadbury peppermint chocolate, or whatever is available in your area.
Sweetened condensed milk – cow’s milk that is sweetened with sugar and heated to remove some of the water content. The result is a concentrated milk product that is thick and sweet, and commonly used in desserts and no-bake slices like this one. Here, it binds the biscuit base together, as well as sweetening the slice. Use full-fat, sweetened condensed milk. Light or skim condensed milk will not set the slice as firmly. Don’t swap for evaporated milk.
Rice Bubbles/Rice Krispies – add texture and chewiness to the slice.
Coconut – this recipe uses desiccated coconut for a finer texture. You could also use the larger, shredded coconut pieces if you prefer, but the texture of the base will turn out slightly different.
Butter – melted butter is used to bind the base together. I recommend using real, unsalted butter rather than margarine or dairy spreads.
Chocolate – milk chocolate is a great option. I also love the contrast of peppermint with a slightly bitter, dark chocolate. Milk, white or dark chocolate can be used, but choose a good quality chocolate that you know and love to eat. It will make all the difference in the final result!

Expert tips

If you don’t have a food processor, crush the biscuits in a bowl using the end of a rolling pin. Some smaller chunks are ok.
The mixture should be fully combined with the condensed milk and butter. If there are dry pockets that have not been fully incorporated, the biscuit base can be crumbly when slicing.
Make sure you press the mixture into the tin very firmly. This will ensure even slices that are easy to cut and hold, without crumbling.
Decorate the slice with your favourite peppermint chocolates or treats. You can add chopped pieces of Mint Slice biscuits, crushed candy canes, Aero chocolate, more Peppermint Crisp or your favourite peppermint treats.
To make the chocolate layer easier to slice, stir 1 tablespoon of vegetable oil or canola oil through the melted chocolate before spreading it over the biscuit base. It will make the chocolate glossy and easier to cut, without cracking.
Leave the sides of the baking paper a little longer and allow them to hang over the sides of the tin, to help remove the slice when it is set.
Storage; this slice can be made ahead and stored in an airtight container in the fridge for 5-6 days.

FAQs

Can I freeze it?

This slice can be frozen for up to 2 months. To freeze, place the slice (whole or cut into pieces) into a good quality, freezer-safe container before placing in the freezer. To thaw, place the slice in the fridge overnight, or sit at room temperature for 1-2 hours before serving. Store in the fridge and consume within 1-2 days of thawing.

How long does it take to set?

It needs to be chilled for at least 2-3 hours before it is sliced. Time in the fridge allows the slice to set and firm up, ready for slicing.

What can I use instead of Arnott’s Marie biscuits?

Any type of sweet, plain tea biscuit will work. In Australia, Nice, Scotch Finger, Arrowroot or plain (not chocolate coated) Teddy Bear biscuits can be used. Elsewhere, Digestives or Graham Crackers are a great alternative.
