Line a medium-sized flat baking tray with parchment paper, and set aside.
Prepare a double boiler with a heat-proof mixing bowl over simmering water.
Add chocolate to the bowl and gently melt over low-medium heat, stirring occasionally.
Once melted and smooth, turn off the heat.
Add half the chopped mint leaves to the melted chocolate and mix until well combined.
Carefully pour chocolate onto the lined tray in a small round.
Take a spatula or spoon and gently spread the chocolate out to 3-5mm thick or until desired thickness.
Sprinkle over remaining chopped mint.
Transfer to the refrigerator and set for 30 minutes - 1 hour or until chocolate has completely hardened.
Remove and set at room temperature for 5 minutes to slightly soften, this makes it easier to cut the bark so it doesn’t crack into tiny pieces.
Cut bark into shards with a sharp knife.
Serve and enjoy!
Notes
Store: Keep mint chocolate bark in an airtight container in the refrigerator for up to 10 days.
Freeze: Wrap each piece securely in cling film, then in foil. Place these in an airtight container and freeze for up to 2-3 months. The double wrapping helps prevent chocolate discoloration, known as bloom.
Thaw: To enjoy after freezing, transfer the container or pieces from the freezer to the refrigerator, letting the bark come to fridge temperature.
