Why you'll love this recipe
Minty. The perfect treat for fans of minty desserts, pairing perfectly with Peppermint Brownies or an Easy Chocolate Mint Mousse
Simple. Made with pantry staples like biscuits, oats, and condensed milk, these truffles are an accessible treat like Rum Balls and Sugar Cookies.
No-Bake. These truffles are quick and easy to make without turning on the oven, just like No-Bake Cherry Ripe Balls or Gingerbread Truffles
Festive. With their green chocolate drizzle and minty Aero topping, they’re an eye-catching addition to holiday spreads, much like Christmas Shortbread Cookies or Reindeer Brownies.
Ingredients
Mint slice biscuits. These form the base of the chocolate mint truffles, with their perfect balance of chocolate and mint.
The US doesn't have mint slice biscuits, but a close alternative would be Pepperidge Farm Mint Milano's, Keebler Grasshoppers or Thin Mints. You may have to adjust the amount of oats depending on how moist the mixture is.
Condensed milk. Adds sweetness and helps bind the mixture together; coconut or oat condensed milk are great dairy-free alternatives but may change the flavour base.
Oats. Provide texture and structure to the truffles; crushed dry biscuits or almond meal can be substituted if preferred.
Cacao powder. Deepens the chocolate flavour; unsweetened cocoa powder or even hot chocolate powder can be used as an alternative.
Peppermint extract. Enhances the minty flavour in the truffles; adjust the amount to taste or omit if the mint slice cookies are strong enough on their own.
Optional toppings. I've used white chocolate with green food colouring for a vibrant festive topping and then added a very small crumble of aero mint to the melted chocolate as decoration. These are optional, but a good drizzle of chocolate always looks good on no bake desserts like a Cherry Ripe Slice.

How to make choc mint truffles
Step 1: Crush the mint slice cookies into fine crumbs using a food processor or by placing them in a ziplock bag and rolling with a rolling pin. Add the oats, cacao powder, and peppermint extract to the crushed cookies and mix well. Stir in the condensed milk until a sticky dough forms.
Step 2: Scoop small portions (about 1–2 tablespoons) of the mixture and roll into bite-sized balls using your hands. Place them on a baking tray lined with parchment paper.
If the mixture is too sticky, refrigerate for 15–20 minutes before rolling.
Step 3: Refrigerate the truffle balls for 20–30 minutes to firm up before decorating.
Step 4: Melt the white chocolate in a heatproof bowl over simmering water or microwave in short bursts, stirring between intervals. Add a few drops of green food colouring to the melted chocolate and mix until the colour is evenly distributed
Step 5: Dip the truffles into the green-tinted chocolate or drizzle it over the top for decoration. Before the chocolate sets, sprinkle or press small pieces of Aero Mint on top for added texture and flavour.
Step 6: Refrigerate the decorated truffles for another 15–20 minutes until the chocolate hardens. Serve chilled as a festive treat or gift them in a decorative box alongside some Gingerbread Cookies and Lemon Shortbread without Eggs.
Top Tip
Sticky Dough? If the dough is too sticky to roll into balls, refrigerate it for 15–20 minutes to firm up before shaping.
Chocolate Melting Tip. To avoid the white chocolate seizing, add a small drop of coconut oil or butter while melting for a smooth, glossy finish.
Storing and Freezing
Store the chocolate mint truffles in an airtight container in the refrigerator for up to a week to keep them fresh and firm. If you'd like to keep them longer, you can freeze the truffles in a single layer in a freezer-safe container for up to 3 months. To enjoy, let them thaw in the fridge for a few hours or at room temperature for 10–15 minutes before serving.
FAQs
Yes. The US doesn't have mint slice biscuits, but a close alternative would be Pepperidge Farm Mint Milano's, Keebler Grasshoppers or Thin Mints.
You can also substitute with chocolate sandwich cookies or a chocolate covered biscuit and add a few drops of peppermint extract to mimic the mint flavour.
Depending on the type of cookie, you may have to adjust the amount of oats depending on how moist the mixture is. Because the mint slice biscuits have a cream in the middle and it's covered in the chocolate, I had to use some of the oats to make sure the mixture formed into balls well.
Yes, these are perfect make-ahead treats! Prepare them up to a week before and store them in the fridge until ready to serve.
Yes, the green food colouring is optional and purely for aesthetic purposes. The truffles will taste just as delicious without it.
