01 - Line an 8x8 inch baking sheet with parchment paper, ensuring complete coverage to prevent sticking.
02 - Set up a double boiler by placing a heatproof bowl over a pan of gently simmering water. Add the chopped white chocolate and stir continuously until completely smooth and melted, taking care not to overheat.
03 - Transfer approximately half of the melted white chocolate to a separate clean bowl, leaving equal portions in both bowls for flavoring.
04 - Sift the matcha powder into one bowl of melted chocolate. Stir vigorously until fully incorporated and the mixture displays a vibrant, consistent green color throughout.
05 - Add the peppermint extract to the remaining bowl of melted white chocolate. Mix thoroughly to ensure even distribution of flavor.
06 - Pour the peppermint-infused white chocolate onto the prepared parchment-lined sheet. Use a spatula to spread it evenly, creating a layer approximately 1/4 inch thick across the entire surface.
07 - Drizzle the matcha chocolate over the peppermint base in parallel lines or random dollops. Gently drag a toothpick or skewer through both layers in swirling motions to create a marbled pattern. Work quickly before the chocolate begins to set.
08 - Immediately scatter the crushed peppermint candies evenly over the swirled chocolate surface, pressing lightly to ensure adhesion.
09 - Transfer the baking sheet to the refrigerator and chill for 30 minutes or until the bark is completely firm and set to the touch.
10 - Break or cut the chilled bark into irregular pieces. Store in an airtight container at cool room temperature for up to 1 week or refrigerate for extended freshness.
