I love making this slice when friends and family pop over because it’s so quick to whip up, and everyone ends up asking for the recipe.

If you’re searching for a festive sweet that’s easy, no-fuss, and utterly delicious, this Peppermint Chocolate Christmas Slice Recipe won’t disappoint. Whether you’re packing it for a holiday party or serving it as a cozy after-dinner treat, the combination of condensed milk, peppermint chocolate, and crunchy candy canes is just irresistible. Trust me—you’ll love how simple it is to impress without spending hours in the kitchen.

Ingredients You’ll Need

The ingredients in this slice work beautifully together to create a rich, minty chocolate experience with a lovely crunch. When shopping, picking quality peppermint chocolate and biscuits really makes a difference in texture and flavor.

Sweetened condensed milk: This adds creamy sweetness and helps bind everything together.
Butter (chopped): Gives richness and helps set the base.
Cadbury Peppermint chocolate: I find this adds that perfect minty, chocolate flavor that defines this recipe.
Plain sweet biscuits (crushed): Using Arnotts Marie or a similar light biscuit gives a great crunch without overpowering flavor.
Cocoa powder: Deepens the chocolate flavor, balancing the sweetness.
Peppermint extract: Just 2 drops lift the mint flavor without being overpowering—taste as you go!
Milk chocolate (melted): This is for the glossy, luscious top layer.
Candy canes (roughly chopped): Adds festive crunch and that classic peppermint bite.
Red & green M&Ms: For a fun, colorful Christmas touch that kids love.

Variations

I’m all about personalizing recipes to suit different tastes and occasions, and this slice is no exception. Feel free to play around with the peppermint intensity or swap out some ingredients for dietary needs—it’s a very forgiving recipe.

Mint Intensity Variation: If you prefer a stronger peppermint kick, add a few more drops of peppermint extract or increase the amount of peppermint chocolate. I’ve done this a few times for extra minty lovers and it’s fantastic!
Dairy-Free Variation: Use dairy-free chocolate and swap butter for coconut oil to keep it vegan-friendly. It changes the texture slightly but still tastes amazing.
Nutty Addition: Toss in chopped hazelnuts or almonds for some extra crunch. I sometimes add these for a little surprise bite that pairs beautifully with the peppermint flavor.

How to Make Peppermint Chocolate Christmas Slice Recipe

Step 1: Gently Melt the Butter and Peppermint Chocolate

Start by placing the chopped butter and peppermint chocolate into a heatproof bowl. Melt them together gently over a saucepan of simmering water or in short bursts in the microwave, stirring frequently. The goal here is to avoid any scorching—take your time, and stir often until everything is smooth and beautifully glossy.

Step 2: Mix in the Sweetened Condensed Milk and Cocoa Powder

Once melted, remove from heat and stir in the sweetened condensed milk and cocoa powder. This mixture forms the rich, sticky center of your slice. It’s thick but pourable, so be patient as you fold it all together evenly.

Step 3: Combine the Dry Ingredients

In a separate bowl, combine crushed plain sweet biscuits, the peppermint extract, chopped candy canes, and half the M&Ms. I like to crush the biscuits finely but leave a few slightly chunkier pieces for texture. Gently fold this into your chocolate mixture until everything is well combined.

Step 4: Press Into a Tin and Chill

Line a slice tin with baking paper and press the mixture firmly and evenly into the base. Pop it into the fridge for about 30 to 45 minutes to set. Patience here is key—this step ensures your slice holds together neatly when you cut it.

Step 5: Add the Melted Milk Chocolate Top and Remaining M&Ms

When the base is set, pour the melted milk chocolate over the top, smoothing it out with an offset spatula. Sprinkle the remaining M&Ms on immediately so they stick before chilling again. Return to the fridge for another 30 minutes, or until the chocolate topping is firm and shiny.

Garnishes

I love adding extra crushed candy canes or even a light dusting of edible glitter to the top when serving—it just adds that festive sparkle. Sometimes, I’ll scatter some whole fresh mint leaves around the plate to complement the peppermint flavor and brighten the presentation.

Side Dishes

This slice pairs beautifully with a hot cup of peppermint tea or a rich coffee, which balances the sweetness perfectly. For Christmas morning, I like to serve it alongside a bowl of fresh berries or a cinnamon-spiced hot chocolate for extra indulgence.

Creative Ways to Present

One festive idea I tried was cutting the slice into tiny squares and piling them on a tiered serving tray decorated with holly branches. It makes for a stunning holiday centerpiece and encourages everyone to grab a bite during gatherings. You can also package individual pieces wrapped in parchment paper tied with red and green ribbon for lovely homemade gifts.

Make Ahead and Storage

Storing Leftovers

I usually keep leftovers in an airtight container in the fridge, where they stay fresh for up to a week. The slice holds up surprisingly well, maintaining that perfect minty crunch without getting soggy. Just be sure it’s sealed to keep the chocolate from absorbing fridge odors.

Freezing

If you want to keep this slice longer, it freezes beautifully. I wrap individual slices tightly in plastic wrap, then place them in a freezer-safe bag. When you’re ready, thaw in the fridge overnight, and they’ll taste almost as fresh as the day you made them.

Reheating

Since this is a no-bake chilly treat, reheating isn’t really necessary or recommended. Instead, just bring the slice to room temperature before serving to let the chocolate soften slightly. I find this brings out the best texture and flavor.

FAQs

Can I use other types of chocolate in the Peppermint Chocolate Christmas Slice Recipe?

Absolutely! While Cadbury Peppermint chocolate gives the slice its signature flavor, you can experiment with different peppermint or dark chocolates depending on your preference. Just be sure the chocolate you choose melts smoothly and complements the mint flavor.
Is it possible to make this slice nut-free?

Yes! This recipe is naturally nut-free, so just avoid adding any nuts if you’re concerned about allergies. Always check labels on chocolates and biscuits to ensure there are no traces of nuts if serving to someone with allergies.
How long does the Peppermint Chocolate Christmas Slice last?

When stored properly in an airtight container in the fridge, this slice will stay fresh for up to one week. Make sure it’s kept cool to maintain the chocolate’s texture and prevent the peppermint from fading.
Can I make this slice ahead of time for holiday parties?

Definitely! This slice is perfect for making a day or two in advance. Store it in the fridge until ready to serve, and it will taste just as delicious. Just add the final garnishes right before serving for the best presentation.
