If using, crush your peppermint candies either in a food processor or in plastic bag using a rolling pin.
In a heatproof bowl, microwave the white chocolate and condensed milk in the microwave for 20sec bursts, stirring between until the chocolate has melted.
Stir in the peppermint extract until spread evenly and pour into a greased and lined 8-inch square baking tin.
Add the crushed candy canes on top and other optional toppings then refrigerate for at least 2hrs until set. Cut into small pieces and enjoy!
Notes
After a few days, your candy might start to dissolve a little depending on the type used. If using crushed candy canes, it's best to make this close to serving.
This is a gluten-free recipe, but always check your ingredients to be sure as there could be cross-contamination warnings.
