01 - Line an 8x8 inch baking sheet with parchment paper and set aside.
02 - Set a heatproof bowl over a pan of gently simmering water to create a double boiler. Add the white chocolate and stir constantly until completely melted and smooth.
03 - Pour half of the melted chocolate into a separate bowl. Whisk the matcha powder into one portion until fully incorporated and vibrant green. Stir the peppermint extract into the remaining bowl.
04 - Spread the peppermint-infused white chocolate evenly across the prepared baking sheet using a spatula, reaching approximately 1/4 inch thickness.
05 - Drizzle the matcha chocolate over the peppermint layer in parallel lines or scattered dollops. Gently drag a toothpick or skewer through both layers to create a marbled pattern.
06 - Immediately scatter the crushed peppermint candies over the surface while the chocolate is still soft. Refrigerate for 30 minutes or until completely set.
07 - Break or cut the bark into 16 pieces. Store in an airtight container at cool room temperature or refrigerate for up to two weeks.
