Ingredients You’ll Need

Each ingredient in this recipe plays a key role in building those classic Christmas tastes and textures. When shopping, look for quality peppermint chocolate and fresh candy canes to really make the flavors pop.

• Sweetened condensed milk: This adds creamy sweetness and helps bind the slice together without needing to bake it.
• Butter: Use unsalted if possible; it adds richness and improves the slice’s texture.
• Cadbury Peppermint chocolate: The star flavor—look for the mint-infused chocolate bars for that refreshing kick.
• Plain sweet biscuits (such as Arnotts Marie): Crushing these creates the crunchy base, so crush them finely but not into dust.
• Cocoa powder: A little goes a long way enhancing the chocolate depth without overpowering.
• Peppermint extract: Just a couple of drops intensify the mint flavor—be careful not to overdo it as it can turn bitter.
• Milk chocolate: For melting and creating a glossy chocolate layer on top.
• Candy canes: Roughly chopped for sprinkling—they add festive color and bursts of minty crunch.
• Red & green M&Ms: These provide a fun, colorful contrast and extra sweetness on top.

Variations

One of the best things about this peppermint chocolate Christmas slice recipe is how easily you can tweak it to fit your taste or dietary needs. I love experimenting a bit depending on who I’m serving it to!

• Variation: For a gluten-free version, swap the plain biscuits for gluten-free digestive biscuits—still delicious, and my gluten-intolerant friends always rave about it.
• Variation: If you want to dial up the mint, add an extra drop of peppermint extract or scatter crushed peppermint candies inside the base mix.
• Variation: For less sweetness, reduce the M&Ms or replace them with dark chocolate chunks for a richer finish.

How to Make Peppermint Chocolate Christmas Slice Recipe

Step 1: Prepare the Biscuit Base

Start by crushing those plain sweet biscuits—you want them broken down into mostly small crumbs but still with a bit of texture for a nice bite in the final slice. I usually pop them in a zip-lock bag and give them a few controlled crushes with a rolling pin. Then, gently melt the butter and combine it with the crushed biscuits, cocoa powder, and the soft chopped peppermint chocolate. This mixture is your base, so mix until it’s evenly coated and looks a bit like chocolatey sand.

Step 2: Mix in the Sweetened Condensed Milk and Peppermint

Pour in the sweetened condensed milk, then add your peppermint extract carefully—it only takes two drops to brighten that peppermint flavor without overwhelming the slice. Stir everything together thoroughly; this sticky mix binds the base and adds that creamy sweetness. If your mixture feels too dry, a tiny splash more condensed milk can help, but be careful not to make it runny.

Step 3: Press into a Lined Baking Tray

Line a square or rectangular baking tray with baking paper, leaving an overhang on the sides to lift the slice out easily later. Transfer your biscuit mix and press it down firmly and evenly—this step is key! I use the back of a spoon or a flat-bottomed glass to pack it down tight, so the slice holds together well once cooled.

Step 4: Top with Melted Chocolate and Festive Decorations

Melt the milk chocolate gently in a heatproof bowl over simmering water or short bursts in the microwave, stirring until smooth. Spread it evenly over the base layer, then quickly sprinkle with the chopped candy canes and red & green M&Ms while the chocolate is still soft. This step is fun because you get to make it look festive and bright—kind of like edible holiday art!

Step 5: Chill Until Set and Slice

Pop the tray into the fridge and let it chill for at least 2 hours, or until completely firm. Once set, use the baking paper overhang to lift the slice out, then cut it into squares or rectangles. A sharp knife warmed under hot water and dried works best for neat edges without cracking the chocolate on top.

How to Serve Peppermint Chocolate Christmas Slice Recipe

Garnishes

I like to keep it simple with extra crushed candy canes sprinkled on top if I’m serving immediately—adds a little extra sparkle and crunch that guests go crazy for. Sometimes, a light dusting of cocoa powder or finely grated peppermint chocolate over the sliced pieces adds a beautiful and tasty finish.

Side Dishes

This slice is pretty rich on its own, but I sometimes serve it alongside a cup of peppermint tea or hot chocolate for a full festive experience. It’s also great with vanilla ice cream if you want a dessert with a little softness to contrast the crunch.

Creative Ways to Present

When I’ve brought this to Christmas parties, I’ve arranged the slices on a festive platter lined with holly leaves (real or faux) and added mini candy canes around the edges for a charming look. Another favorite trick is stacking the slices as little “Christmas trees” tied with red ribbon—easy to do and always gets a smile.

Make Ahead and Storage

Storing Leftovers

I usually store any leftovers in an airtight container in the refrigerator. The slice keeps really well for up to a week, and the flavors sometimes taste even better the next day as everything has time to meld. Just be sure to separate layers with parchment paper if you’re stacking the pieces to prevent sticking.

Freezing

This peppermint chocolate Christmas slice recipe freezes beautifully. I wrap individual slices tightly in plastic wrap and place them in a freezer bag. When you want a treat, just thaw them in the fridge overnight to keep that perfect texture and flavor intact.

Reheating

Since this slice is best served chilled, I usually don’t reheat it. But if you prefer a softer chocolate layer, leave it at room temperature for 10-15 minutes before serving. Avoid microwaving as it can melt the chocolate topping unevenly and make the base a bit soggy.
