An easy no bake - no fail slice
This easy, no-fail no bake peppermint slice is an all-time favourite recipe of mine.
It has a chocolate biscuit base, a sweet peppermint filling and a simple chocolate icing on top. There's no baking required, and it's a great recipe to make ahead for the smoko tin, a shared morning tea or when you need to take a plate.
You'll notice I use chocolate icing instead of melted chocolate on top. I don't particularly like cutting slices with a solid chocolate topping because I can never get through the whole slice without cracking a few tops! Chocolate icing makes it much easier to cut into tidy pieces.

I don’t particularly like cutting slices with solid chocolate toppings, which coincidentally a lot of peppermint slice recipes have, because I can never get through the whole slice without cracking a few tops. With this recipe you won’t have to worry about that.
It’s got a very delicious chocolate icing instead.

If you have a copy of my book 'A High Country Life' you may have noticed a mistake in this recipe.
Grab a pen and we can fix it!
Turn to page 182 and change the amount of condensed milk from one whole can - to only half a can

Things to consider when you make this slice;
- 250 grams is equivalent to one packet of wine biscuits
- This recipe is easily doubled and who would complain. It’s tasty and no-one likes a half can of condensed milk getting lost in the fridge.
- If you don’t have any wine biscuits - you could use any plain biscuit.
- Quite often if I have a biscuit baking catastrophe I will blitz the biscuits and freeze the crumbs. They are perfect for reusing in a no-bake biscuit base recipe.
- I buy my biscuit crumbs from the bulk food store.
- If you don’t have a food processor to blitz the biscuits into crumbs. Place them inside a pillow case and smash with the wooden rolling pin (I remember this being one of my favourite jobs as a kid).
- You could use either the microwave or stove top to melt the ingredients.
Peppermint Essence
I use peppermint essence for this slice. Two teaspoons gives it a lovely peppermint flavour, but you can always add a little less if you prefer a more subtle mint flavour.
If you're using peppermint oil instead, remember that it is much stronger than peppermint essence or extract, so you'll need considerably less. Add it carefully and taste as you go.
Getting Prepared
Line a 28cm x 18cm dish.
Blitz a packet of wine biscuits in a food processor.
Melt together all the remaining ingredients for the base.

Combine the biscuit crumbs with the wet ingredients and mix well.
Tip into the lined dish and using a wet hand, press down to make an even surface.
To smooth the top of the base out - place a piece of baking paper on top and use the back of a spoon to firmly smooth the surface.

Pop in the freezer while you make the peppermint filling
For the Peppermint Filling;
Mix all the ingredients together.
Add boiling water a little at a time, and mix using a knife, until you have a smooth paste.

No Bake Peppermint Slice FAQs
How should I store peppermint slice?
Store your peppermint slice in an airtight container in the fridge. I actually think it's particularly good served cold straight from the fridge!
Can I make peppermint slice ahead of time?
Absolutely. Because this is a no bake slice, it's a great one to make the day before you need it. Leave it in the fridge to set and slice it when you're ready to serve.

How do I cut peppermint slice neatly?
How do I cut peppermint slice neatly?
Make sure the slice is completely set before cutting. I use a hot knife – run it under hot water, dry it with a clean tea towel and then cut. Repeat between cuts for lovely tidy pieces.
One of the reasons I use chocolate icing instead of melted chocolate on top is because it makes the slice much easier to cut without the top cracking.
And don't worry if they're not all perfectly even – I can assure you no one at smoko will complain!
