No-Bake Peppermint Slice

Happy Sunday! I’ve been busting to share this recipe with you as it’s one of my favourites I’ve ever developed - it’s a No-bake Peppermint Slice! I developed this for the Holiday Cookie issue of Bake From Scratch, along with three other recipes which you should check out in the issue, but this one was maybe the simplest but most definitely my favourite.

One thing that I miss the most about home is the mint slice biscuits. I think they are technically Australian, but they were my favourite growing up, and something that still comes out when it’s cup of tea time at home. It’s a crunchy chocolate base, then a super minty filling, and a dark chocolate coating. I can eat about 10 of them in one go, and they are always on the list of things to have brought over when people come and ask if we want anything.

There’s also a bakery peppermint slice that is a NZ sweet staple, but the biscuit is absolutely my favourite, so I wanted to get that flavour profile and turn it into a slice / bar for all the Americans here. I think I managed to get the balance just right - I used a chocolate graham cracker base, with a teeny bit of coconut for some texture, then a super minty topping which is basically just a stir together situation, and then a super smooth, super satisfying smooth chocolate topping. The whole thing is no-bake, and super fuss free, which makes it perfect for anytime, but particularly for the upcoming holiday season. It keeps forever in the fridge, however judging on how many pieces I have eaten since I re-made this this week, it doesn’t last long in my house, and it won’t last long in yours either. I hope you give this guy a try if you’re in the market for a super easy chocolate peppermint slice recipe - this one is a keeper. x

Components of No-Bake Peppermint Slice

This recipe is super easy to make, and has a few components to it. You can make it all at once or spread out your timing a little to fit your schedule. It keeps super well in the fridge in an airtight container, although I find it never lasts long around my house!

• Chocolate Graham Cracker Base - I added some coconut to the chocolate crumb crust base. If you're in NZ and you can't get graham crackers, digestives or a mixture of digestives and wine biscuits would work great. The base gets made and then hangs out in the freezer while the topping is made.
• Peppermint Icing - This is what gives peppermint slice the super minty flavour. A thin layer of peppermint icing, which is just a mix together situation and comes together really quickly! Powdered sugar, vanilla, a wee bit of salt and peppermint extract are mixed with boiling water to form a smooth filling which is poured over the base.
• Chocolate Topping - I just make this in the microwave! It's dark chocolate mixed with just a wee bit of neutral oil, which gives it some shine and also helps to prevent cracking when you cut the slice up.

A few wee tips for No-Bake Peppermint Slice:

• These don’t really need toooo many notes, but I will say - make sure that they are nice and cold before you cut them. You can wait until the chocolate is set and then throw them in the freezer for a bit if you need to, or a few hours in the fridge will do well. If you don’t wait long enough then it’s no worries at all, but they might get a little squishy as you cut them.
• Start with 3 Tbsp water in the filling. It won’t seem like much, but you don’t need too too much to melt down the powdered sugar. Add in an extra teaspoon of water at a time if it’s too thick - I usually need one or two to get it to the right consistency.
• If you wanted to make mega amounts of this (which would work great), then you could double the mixture and make it in a 9x13 pan. It keeps for yonks in the fridge so would be perfect for keeping on hand.

A note on salt and oven temperature

It is important to note the type of salt that is called for in a recipe. I use Diamond Crystal salt throughout my recipes - if you use a different sort of kosher salt or regular table salt you will need to adjust accordingly as some salt is 'saltier' than others. Morton's salt is twice as salty, so you will need half the quantity. Same goes for a regular table salt. I am working to get gram measurements throughout my recipes for salt but still getting there.

All oven temperatures are conventional unless otherwise stated. If you are baking on fan / convection, you will need to adjust the temperature. An oven thermometer is a great investment to ensure that your oven is the correct temperature.

Using the double / triple function in the recipe card

You will notice that there is a '1X' '2X' '3X' button in my recipe card. This can be used for doubling or tripling a recipe. However, please note that this only doubles the ingredient quantities in the ingredients list and NOT in the method. If there are quantities or pan sizes in the method of the recipe (for example weigh out 150g brown butter), you will need to scale this number manually. It will also not change the baking time in the recipe so you will need to adjust this yourself too. It is always a good idea to read through a recipe fully before doubling it just to check this. If you would like to scale this recipe or convert for another pan size, use my calculator!

Why is this recipe in grams?

I post my recipes in grams as it is the most accurate way to bake. Cups are not only inaccurate but they vary in volume worldwide. There is no way for me to provide one cup measure that works for everyone. However, posting in weight fixes this issue. If you would like the recipe in cups you are welcome to convert it yourself via google, but please do not ask me to do it for you as I am not comfortable providing a recipe using a method that I have not tested. Baking with a scale is easy, accurate, and also makes cleanup super simple. Here is the scale that I use if you would like a recommendation! Here's to accurate baking!
