Peppermint Slice

This Peppermint Slice Recipe has been in my favourites collection for a long time, and I reckon you might just add it to yours.

The combination of sweet, minty cream filling, crunchy choc biscuit base and smooth chocolate is absolutely more-ish.

You’ve been warned!

Peppermint Slice: a bakery favourite

This triple-layered slice is one you might find at a traditional country bakery.

It’s popularity comes down to that blend of chocolate and peppermint, which is a treat for both the eyes and taste buds.

There’s also the contrast of the crispy, crunchy biscuit base and the creamy smoothness of the top two layers – adding to the temptation.

This recipe is one from my Mum’s bakery collection. She worked in country bakeries in the Hunter Valley for decades and earned a reputation for her AMAZING slices. 

There are so many of these wonderful slice recipes that it’s hard to pick a favourite.

But this one is my husband’s all-time favourite and is often requested at birthday time.

And it’s definitely high up on my (very long) list of favourites.

Making this popular slice

Have you got all of the ingredients?

Here’s what you’ll need:

  • plain flour
  • cocoa
  • brown sugar
  • desiccated coconut
  • butter, salted and unsalted
  • icing sugar
  • peppermint essence
  • green food colouring
  • chocolate (milk or dark, whatever you prefer). 

You can find the precise measurements for the ingredients in the recipe card at the end of this post.

You’ll also need a slice tin, approximately 28cm x 18cm.

The process is then fairly straightforward. Mix together the base ingredients before baking the first biscuit layer. 

Once the base is cooked and cooled, you whip together the peppermint cream ingredients and spread the second layer over the biscuit base.

You top this slice off by melting the chocolate and pouring it over the peppermint cream.

Let the slice set in the fridge and then cut into squares.


And, as mentioned above, there are more details to be found in the recipe card at the end of this post.

Calories: 262kcal



  • 1 cup plain flour
  • 1 tablespoon cocoa
  • 1/2 cup brown sugar
  • 1/2 cup desiccated coconut
  • 125 grams butter, melted

Peppermint Filling

  • 200 grams unsalted butter (salted butter will work too if you don't have unsalted butter)
  • 3 cups icing sugar
  • 1/2 teaspoon peppermint essence
  • 3-7 drops green food colouring

Chocolate Topping

  • 300 grams milk or dark chocolate



  • Pre-heat oven to moderate-hot (180 degrees celsius, fan-forced).
  • Grease a slice tin (28 x 18cm) and line with baking paper, leaving extra on each side (to pull the slice from the tin once cooked).
  • Mix all ingredients together. Press into slice tin and level out with the back of a spoon.
  • Bake for 20 minutes.

Peppermint Filling

  • Beat butter until a pale colour.
  • Add icing sugar gradually, beating after each addition. Beat until fluffy.
  • Add peppermint essence and green colouring and beat again.
  • Once base is completely cooled, spread peppermint filling evenly over the base.

Chocolate Topping

  • Melt chocolate by placing in microwave and heating with 20 second bursts (stirring between each burst).
  • Pour melted chocolate over cream filling, tilting tin from corner to corner to spread chocolate completely over the peppermint filling.
  • Place in fridge for 15-30 minutes. Ideally, the chocolate shouldn't be completely set when cutting (it will crack as you're cutting if it's too hard).
  • Once set, remove slice from tin by lifting edges of baking paper, cut into squares and return to the fridge. (And if you've left the slice in the fridge for longer, just let the slice rest at room temperature for half an hour before cutting into squares.)

I made this at Christmas and it was a huge hit. Everyone loved it and I think I ended up making 3 batches over a couple of weeks. I’m keen to try a cherry ripe version as well.
