Ingredients You’ll Need

These ingredients come together like a dream, blending creamy textures with crunchy bites and that unmistakable peppermint hit. When shopping, look for good-quality peppermint chocolate and fresh candy canes for the best flavor and crunch.

• Sweetened condensed milk: This brings that rich, gooey base and sweet creaminess that holds the slice together beautifully.
• Butter: Use unsalted and chopped for even melting; it enriches the texture and flavor.
• Cadbury Peppermint chocolate: This is key for the festive peppermint flavor and that smooth chocolatey goodness.
• Plain sweet biscuits (like Arnotts Marie): Crushing these adds a delightful crunch without overpowering the peppermint.
• Cocoa powder: Just a bit to deepen the chocolate flavor without bitterness.
• Peppermint extract: A couple of drops elevate the slice, making sure the peppermint stands out.
• Milk chocolate (melted): To pour over and set, creating that fudgy top layer everyone loves.
• Candy canes (roughly chopped): Adds crunch and festive flair, plus extra peppermint bursts within each bite.
• Red & green M&Ms: For that fun, colorful Christmas touch—plus a little extra sweetness.

Variations

One of the best parts about this Peppermint Chocolate Christmas Slice Recipe is how easy it is to make your own. I often throw in a few tweaks depending on what I have on hand or who I’m serving it to, so feel free to personalize it and make it truly yours.

• Dairy-free version: Swap out regular butter for a plant-based alternative and use dairy-free chocolates. I tried this once for a friend, and it was just as addictive!
• Nutty addition: Add crushed roasted almonds or pecans for an extra layer of crunch—just make sure no one has nut allergies.
• Mint alternative: If you’re not into peppermint extract, try orange zest instead for a chocolate-orange twist I once experimented with for New Year’s.

How to Make Peppermint Chocolate Christmas Slice Recipe

Step 1: Melt Your Base Mixture

Start by gently melting the butter and Cadbury peppermint chocolate together in a heatproof bowl over simmering water, stirring until silky smooth. It’s a cozy process that fills your kitchen with that classic chocolate scent. Be patient and keep the heat low—if the chocolate gets too hot, it might seize up. Once melted, remove from the heat and quickly stir in the sweetened condensed milk and peppermint extract until everything’s perfectly combined.

Step 2: Mix in Your Dry Ingredients

Now toss in your crushed biscuits and cocoa powder, folding them into the chocolate mixture so every crumb is coated. The key here is not to overmix, or you risk turning it into a doughy mess. Just enough to combine everything evenly. Then stir through most of your chopped candy canes and M&Ms, reserving some for decoration.

Step 3: Press and Chill

Line a baking tin (I use a 20x30cm one) with baking paper and press the mixture down firmly but gently, creating an even layer. This helps the slice hold together once set. Pop it in the fridge for about 2 hours or until firm—it’s hard to wait, but trust me, it’s worth it!

Step 4: Add the Milk Chocolate Layer

Once chilled, pour your melted milk chocolate over the slice evenly, then sprinkle the reserved candy canes and M&Ms on top. This layer sets quickly and adds that irresistible fudgey top with a festive crunch. Chill again for at least an hour until completely firm before slicing into squares or bars.

How to Serve Peppermint Chocolate Christmas Slice Recipe

Garnishes

I love topping my slices with extra crushed candy canes or even a light dusting of icing sugar—it looks like snow and feels festive. Sometimes I add a few fresh mint leaves for a pop of color and to hint at that peppermint flavor inside.

Side Dishes

Serve these slices alongside a warm cup of peppermint tea or a rich hot chocolate. They also pair wonderfully with a dollop of whipped cream if you’re hosting a holiday dessert table. I like to keep it simple to let the slice shine.

Creative Ways to Present

During Christmas, I’ve arranged these slices on a festive platter surrounded by holly sprigs and miniature fairy lights. For a party, cutting them into bite-sized pieces and placing them in decorative cupcake liners makes them easy to grab and share. It’s those little touches that make a difference!

Make Ahead and Storage

Storing Leftovers

I keep any leftovers in an airtight container in the fridge, and they stay fresh for up to a week. Just make sure to separate layers with parchment paper so they don’t stick together. The chocolate keeps its texture well, and the peppermint stays fresh.

Freezing

I’ve had great luck freezing this slice! Cut into pieces first, then wrap individually in cling wrap and pop in a freezer-safe bag. They keep well for up to two months, so it’s a fantastic way to prepare for the holidays early or keep a stash of treats on hand.

Reheating

This slice is best enjoyed cold or at room temperature, so reheating isn’t necessary. If you like a softer texture, just let a frozen piece thaw in the fridge overnight or at room temp for about 30 minutes before enjoying.
