Mint Slice – No-Bake Recipe
*This post may contain affiliate links. Please see my disclosure for more details!*
Easy no-bake mint slice traybake with a biscuit base, easy mint filling, and a delicious chocolate topping!
Mint slice
Now, mint slice has always been one of my favourite things to eat EVER since I can remember. We had it every now and again at my Junior School as dessert and it was THE BEST!
But since I was little I have endeavoured to recreate the delicious biscuity, minty, chocolatey, scrumptious dessert that made me obsessed with baking. I would even always tease my friends throughout high school because they wanted to be able to make it too, but me being me, I kept it a secret.. until now!
Simple recipe
Honestly some people will read the recipe and probably think “is that it?!” or think its a variation on a different type of bar (Nanaimo bar) but honestly.. it’s as close to the mint slice that I can remember from my early school years that I can create!
This recipe is so easy to make, and basically the minty no-bake version of millionaires shortbread! You can have the same biscuit base, the same chocolate topping, but you just swap out the caramel for a delicious mint flavour – simple!
Biscuit base
I use digestives for my biscuit base as they are my favourite! And this may sound a little odd… but the biscuit base is made up of the biscuits, melted butter… and condensed milk. Now, before you judge… roll with me. Without the condensed milk, it really is just a cheesecake base, but with the condensed milk? It makes it slightly squidgy, and also combines it perfectly!
I wouldn’t suggest using condensed milk when you make a cheesecake, as you don’t need the sweetness of the squidgy side of things… but for this it is perfect. Of course though, if you don’t want to use it, up the butter to 200g!
Filling
For the mint filling, I like to keep things simple. There are many ways you could do this – but I genuinely just find that icing sugar, water, mint extract and colouring is the best. The colouring is completely optional, it doesn’t have to be green… but otherwise, three simple ingredients!
Topping
For the topping, it’s just chocolate. Top tip though – if you want your chocolate to be easier to cut, add in 1-2tbsp of vegetable/sunflower oil to make it easier to cut afterwards!
Enjoy!!
Mint Slice!
Ingredients
Biscuit Base
- 400 g digestives
- 150 g unsalted butter (melted)
- 100 g condensed milk
Mint Filling
- 350 g icing sugar
- 2 tsp peppermint extract
- Green food colouring
- 2-3 tbsp water
Topping
- 300 g milk chocolate
Instructions
- Line a 9x9" square tin with parchment paper and leave to the side for now.
- Blitz the biscuits in a food processor until they are a fine crumb – mix in the melted butter and condensed milk blitz again until combined!
- Press into the bottom of the tin and chill whilst you make the icing!
- Mix the icing sugar, peppermint essence, and food colouring and enough water till it forms a relatively thick paste – spread across the biscuit base.
- Start with less water and gradually add in a tiny amount more – you don’t want it runny, you have to be able to spread it but still be thick. Leave to set for an hour.
- Melt the chocolate in a heatproof bowl and pour on top of the icing (trying not to disturb the icing too much) and leave to set in the fridge till solid, so probably an hour or two!
- Cut the mint slice into 16-25 pieces and enjoy!
Notes
- Keep in an airtight container in the fridge so that it doesn’t melt everywhere!
- This will last in an airtight container in the fridge for one week!
- You don’t have to include the condensed milk in the base but I prefer it to be slightly softer! If you don’t want to use it, bump the butter up to 200g.
- You can use 1-2tbsp of oil in the chocolate to make it easier to cut after it has set if you prefer!
ENJOY!

Love this so much ! How could you adapt the base to be milk free ?
Great recipe, how do I make the base chocolate? Thanks so much.
You can add 35-50g of cocoa powder to the base when you make it x
Easy to make and taste delicious. Everyone loved them!
I make these but I make a shortbread for the base instead of a biscuit base.
As my husband says these are moreish, have to hide them sometimes or my visitors would get none x
I remember having this at school and loved it so was keen to try and recreate it – this was so easy to make and went down a treat at a school bake sale – vanished within minutes 😂 Thanks for a great recipe!
Hi Jane, I love a peppermint slice but how could I make this with a darker chocolate topping please? I’m not sure on ratios.
Hiya! Use the same quantity but just dark chocolate! Hope this helps! x
[…] the filling, it’s similar to my mint slice filling – simply with out the colouring. I needed it to actually seem like the center of an after eight, […]
Hi, I’m looking to make this for my mother in law. Can you advise how much food colouring to put in please? X
How much depends on the brand unfortunately – as they can really vary in strength!!
Hey Emily, just do a few drops at a time. I just made it there and used 3 drops of the dr okter bright green gel x
Jane how do you measure your condensed milk
Hey, weigh it in grams it is easier x
Being from America, the digestive biscuits are a foreign concept. If you had to choose from the following brands:
Gullon, McVitie’s, or Fox’s, which would you choose? Or doesn’t it matter?
I would use graham crackers!
[…] I’m planning on bringing some to the park for a playdate today. This is the recipe I used: https://www.janespatisserie.com/2015/03/13/mint-slice-no-bake-recipe/ I think I’m going to make some fudge today to use up the rest of the condensed milk […]
Hi my chocolate looks nothing like this when I cit it just completely cracks everywhere any tips
I recommend using a large sharp knife – and just cut down in one go – other people say heat the knife, or score the chocolate before it’s fully set etc!
Hi. Can I add caramel instead of the mint? Would that work please? Thanks!
You can’t use ready made caramel as it doesn’t set – it’s worth looking at one of my many millionaires shortbread x
This is an awesome recipe! I bulk up the mint icing filling as I like it a bit thicker but apart from that it’s amazing! Perfect biscuit ratio too so not sure how anyone would ever have a problem 😊👌
So glad you enjoyed it!! X
Can you freeze this recipe?
The icing part may go a little odd potentially, but otherwise it’s fine to freeze!
Really easy to make. My 13yr old son made it before I had and it tasted amazing!
Please could you tell me how many calories per sluce
Hi I was just wondering what company do you use for your extracts (peppermint…the orange idea also sounds exciting) thank you x
For vanilla, lemon, orange, peppermint I use Nielsen massey! x
Oh my word! Just found this from your Mint Aero Rocky Road… Tesco used to sell something like this in the fresh bakery bit. Haven’t seen any recipe like it! Good work Past Jane!!!!
I made this to exact instructions and it just fell apart I
Couldn’t even get it out of the tin very disappointed
For the biscuit base you really do need to make sure the biscuit is fine crumb, and press it down firmly. Also, as mentioned on the recipe you need to line your tin – otherwise you probably will struggle a bit unfortunately! x
Yes I did all that as I’m use to making cheesecake in very similar manners but as soon as I cut into it would just fall apart I may bake it next time
You can certainly bake it for a bit first if you want – or try it more like a cheesecake style as mentioned with just butter/biscuits rather than condensed milk!
Hi Jane! Do you think this could work by using orange extract and orange food colouring to make an orange flavoured slice instead? Thanks 🙂
Yes definitely!
I would love to make these for my friends but I don’t have a food processor. I usually use a pestle and mortar to crush biscuits for cheesecakes as I find it gives a finer crumb, so do you think I could do it with a bit of elbow grease or is the food processor a necessity?
Noo it would be fine! I just like my food processor as I find it easier ?
Ooh thanks. I’ll let you know how they go down. My mates love my mint Oreo cheesecake so this should be a winner 🙂
P.S. they loved the Rolo fudge and Malteaser cheesecake so far
Can I ask what else can I make with the remaining condensed milk in this recipe
Search ‘condensed milk’ on my website and you’ll see 🙂
Haven’t made any yet but do intend to do so!!!!!!!!!!!!
Wow these look beautiful and delicious! I love minty chocolate!
Thank you so much!!
On my to-do list! Simple and tasty, just how I like it!
Thank you so much, I hope you enjoy it!!
Yum, these look beautiful! I want to make them for St. Paddy’s Day – do you think it would work to add a drop or two of green food colouring to the mint layer?
Thank you! I am making some for St Paddy’s Day too! And yes, I tend to always put green food colouring in as it makes it look minty, but I didn’t have enough so it was so pale you couldn’t see it!
My boyfriend saw this and I think I need to make it for him now. Millionaire Shortcake is his favorite and he also loves mint!
Haha mines the same! I’m sure he will love it!!
Oh this looks so good
Hehe thank you!!
That looks absolutely delicious ?
Thank you so much!! ?
Ooh i think i’ve found my Sunday activity! Thank-you for sharing! 🙂
Oh thank you Vicky!! I hope you enjoy it!
