This Peppermint Slice Recipe is one to add to your favourites collection. The combination of sweet, minty cream filling, crunchy choc biscuit base and smooth chocolate is very, very moreish. 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 with 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 on my (long) list of favourites.

Ingredients

Base

  • 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

Instructions

Base

  • 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 to set.
  • Once set, remove slice from tin by lifting edges of baking paper and cut into squares.
