Ingredients You’ll Need

The ingredients for this Christmas Peppermint Slice Recipe all come together beautifully to give you a no-fuss, irresistible treat. You’ll want to grab some quality biscuits and fresh peppermint essence to get the best flavor.

• Butter: Unsalted works best so you control the salt level, and it gives a silky texture to the base.
• Cocoa powder: I use natural cocoa powder here, which adds that rich chocolate depth without too much bitterness.
• Brown sugar: Adds a lovely caramel undertone; make sure to pack it lightly when measuring.
• Vanilla extract: Just a touch to round out the flavors and complement the cocoa.
• Milk: Whole milk or any milk you like will do to help bind everything together.
• Marie or wine biscuits: These are classic for no-bake slices—crush them but keep some texture for that perfect bite.
• White chocolate: For the topping, use a good quality bar for smooth melting and sweetness.
• Vegetable oil: Mixing this with white chocolate helps keep the topping glossy and soft, not hard.
• Peppermint essence: The star of the show—make sure it’s pure peppermint extract, not artificial flavor.
• Christmas M&Ms: Adds festive color and a bit of crunch that kids and adults love.
• Candy canes: Crush them roughly so you get those minty shards that sparkle on top.

Variations

I always encourage making this Christmas Peppermint Slice Recipe your own. Over the years, I’ve tried a few tweaks to suit what I have on hand or to cater to different tastes—all of which turned out great!

• Nutty Twist: I once threw in some chopped pistachios on top alongside the candy canes—it gave a lovely crunch and a nice color contrast.
• Vegan Version: Swap the butter with a dairy-free alternative and use dark chocolate instead of white for the topping—still delicious!
• Extra Minty: Add a bit more peppermint essence to the topping if you’re a peppermint fanatic like me.
• Gluten-Free: Use gluten-free biscuits to keep the texture but make it friendly for gluten-sensitive folks.

How to Make Christmas Peppermint Slice Recipe

Step 1: Prepare the Base Mixture

Start by gently melting the butter in a saucepan over low heat—don’t rush it or let it bubble! Once melted, whisk in the cocoa powder and brown sugar until everything’s combined and smooth. Stir in the vanilla extract and milk last, ensuring the mixture is silky and well blended. This base is where that rich chocolatey goodness begins, so take your time and keep the heat gentle.

Step 2: Add the Crushed Biscuits

Once your base is ready, remove it from the heat and fold in the crushed Marie or wine biscuits. Don’t crush them too finely—leave little chunks for texture. I usually crush them by hand inside a sealed bag so they don’t end up as dust. This step is key because it creates the perfect chewy, crunchy balance.

Step 3: Press into a Pan and Chill

Press the biscuit mixture evenly into a lined slice tin or baking dish, using the back of a spoon or your hands (slightly damp hands help!). Smooth the surface so it’s level, then pop it in the fridge for about 30 minutes to set. This chilling makes the slice easier to cut and ensures it has that satisfying firmness.

Step 4: Make the Peppermint Topping

For the topping, melt the white chocolate gently with the vegetable oil over a double boiler or in short bursts in the microwave, stirring frequently so it doesn’t seize. Stir in the peppermint essence right away—this freshens everything up wonderfully. This step is where you get that glossy, creamy peppermint layer that’s just so dreamy on top.

Step 5: Decorate and Chill Again

Pour the peppermint white chocolate topping over the chilled biscuit base and spread it evenly. Then sprinkle your Christmas M&Ms and crushed candy canes over the wet topping—don’t be shy here! I love how the crushed canes add a snowy sparkle effect. Return it to the fridge for another 2 hours or until fully set before slicing.

How to Serve Christmas Peppermint Slice Recipe

Garnishes

I usually keep the garnishes simple—just a light dusting of extra crushed candy canes right before serving for that extra festive touch. Sometimes, if I’m feeling fancy, I add a few fresh mint leaves around the platter to complement the peppermint flavor and add a pop of green.

Side Dishes

This slice shines on its own, but I’ve found it pairs wonderfully with a cup of peppermint tea or hot chocolate topped with whipped cream. For a party, I like serving it alongside a mix of other small festive treats like gingerbread cookies or spiced nuts to balance flavors and textures.

Creative Ways to Present

Once, for a Christmas gathering, I cut the slices into bite-sized squares and placed them on decorative toothpicks—instant Christmas cake pops without the fuss! Another fun idea is layering the slices in clear glass jars tied with a festive ribbon as edible Christmas gifts. Presentation makes it feel even more special and festive!

Make Ahead and Storage

Storing Leftovers

I store leftover Christmas Peppermint Slice in an airtight container in the fridge. It keeps well for up to a week, though it rarely lasts that long around here! Keeping it chilled helps the topping stay firm and the base nice and chewy.

Freezing

I’ve frozen this slice a couple of times by wrapping individual pieces in cling film and then storing them in a freezer container. When you’re ready, just let them thaw in the fridge overnight. The texture holds up surprisingly well, and it’s an easy way to prepare in advance for the holidays.

Reheating

Since this is a no-bake slice with a chocolate topping, you don’t really want to heat it up—it’s best enjoyed cold or at room temperature. If you prefer slightly softer chocolate, just leave a piece out for 10-15 minutes to gently come to temperature before digging in.
