    No-Bake Peppermint Slice

    Ingredients For Peppermint Chocolate Slice

    • sweetened condensed milk
    • butter
    • Cadbury peppermint chocolate 
    • cocoa powder
    • peppermint extract (optional)
    • plain sweet biscuits (like Arnott's Marie biscuits or a plain sugar cookie or butter cookie). 
    • white chocolate
    • coconut oil
    • green food colouring
    A block of peppermint chocolate, condensed milk and butter.

    How To Make Peppermint Chocolate Slice 

    Step 1 - Crush the biscuits

    Use a food processor or Thermomix to crush the biscuits into crumbs (it's fine for some larger chunks to remain). Stir through the cocoa powder.

    How To Swirl Food Colouring Through Chocolate

    A chocolate swirled top layer is my absolute favourite way to finish a no-bake slice. It looks so effective but is actually really simple to do (just like in my pink Turkish Delight Slice version). 

    Here's my top tips for getting this pretty finish to your white chocolate layer: 

    1. Add coconut oil to the white chocolate when melting (this makes it easier to swirl the food colouring through later on). 
    2. Work quickly - you don't want the chocolate to set while you're still swirling!
    3. Add small (think... tiny!) drops of food colouring all over the slice - if the drops are too big, they won't set. 
    4. Use a skewer or a knife to swirl the food colouring through in circular motions. 

    Watch the video below to see it in action!

    • 2 tbs coconut oil
    • 3-4 drops green food colouring

    Instructions

    Conventional Method

    • Grease and line a 16cm x 22cm rectangular slice tray with baking paper and set aside.
    • Crush the biscuits in a food processor (leaving a few larger chunks). Place into into a mixing bowl.
    • Sift the cocoa into the bowl.
    • Melt the butter, peppermint chocolate and condensed milk in the microwave on 30 second bursts (50% power) until melted and combined - stir between each burst.
    • Pour the chocolate mixture over the biscuit crumbs. Add the peppermint essence and mix well to combine.

    • Meanwhile, melt the chocolate and coconut oil in the microwave on 50% power (stirring regularly). Pour the melted chocolate over the slice.
    • Working quickly, add a couple of drops of green food colouring to the white chocolate and swirl with a skewer.
    • Place the slice into the fridge until it feels 'tacky' but the chocolate hasn't set completely hard.
    • Take out of the fridge and slice into squares.
    • Store in an airtight container for up to 5 days.

    Thermomix Method

    • Grease and line a 16X22cm rectangular slice tray with baking paper and set aside.
    • Place the biscuits into the TM bowl and roughly chop by pressing Turbo 5-10 times (you still want a few larger chunks). Remove and set aide.
    • In a clean TM bowl, place the condensed milk, butter and peppermint chocolate. Melt on 80 degrees, 3 minutes, Speed 2.
    • Add the cocoa powder and peppermint essence and mix on Speed 5, 10 seconds. Scrape down the sides of the bowl.
    • Add the crushed biscuits and mix on Reverse Speed 3 (using the spatula to assist) until combined (you may need to scrape down the sides of the bowl and repeat).
    • Spread mixture into a baking paper lined slice pan.
    • Melt the chocolate and coconut oil in a clean Thermomix bowl on 80 degrees, 3 minutes, Speed 2.
    • Pour the chocolate over the slice.
    • Working quickly, add a couple of drops of green food colouring to the white chocolate and swirl with a skewer.
    • Place the slice into the fridge until it feels 'tacky' but the chocolate hasn't set completely hard.
    • Take out of the fridge and slice into squares. Store in an airtight container for up to 5 days.

    Notes

    RECIPE TIPS & TRICKS
    Types Of Cookies To Use: You can use any type of plain sweet cookies for the base (like graham crackers if you’re in the US, Arnott’s Marie biscuits if you’re in Australia or digestive biscuits).
    Peppermint Chocolate: Cadbury peppermint chocolate can be bought in any supermarket in Australia or New Zealand. It has a milk chocolate outer layer filled with smooth peppermint filling. You can substitute for any soft filled peppermint chocolate block. 
    Peppermint Extract: Adding a couple of drops of peppermint extract to the slice gives it an extra peppermint flavoured boost. You can purchase peppermint extract from the baking section of most supermarkets (near the vanilla extract). You can omit the peppermint extract if you prefer. 
    Green Swirled Chocolate Layer: To achieve the green swirled effect, add coconut oil to the white chocolate when melting (as this makes it easier to swirl the food colouring through). Add tiny drops of food colouring all over the slice and use a skewer or a knife to swirl the food colouring through in circular motions. 
    Cutting The Slice: To cut the perfect slices, use a hot dry knife (run it under very hot water and then dry it with a tea towel) to gently score the chocolate layer. Once the chocolate layer has been scored through, press down firmly with the knife. 
    Storing The Slice: Store the slice in an airtight container for up to 5 days or freeze for up to 2 months. The slice can be stored in the fridge or at room temperature.
