01 - Line an 8x8 inch baking sheet with parchment paper, ensuring complete coverage to prevent sticking.
02 - Set a heatproof bowl over a pan of gently simmering water to create a double boiler. Add the chopped white chocolate and stir continuously until completely smooth and melted.
03 - Remove approximately half of the melted white chocolate to a separate clean bowl, creating two equal portions for flavoring.
04 - Whisk the matcha powder into one bowl of melted chocolate until fully incorporated and vibrantly green, ensuring no lumps remain.
05 - Stir the peppermint extract into the remaining bowl of white chocolate until evenly distributed throughout.
06 - Pour the peppermint-infused white chocolate onto the prepared baking sheet and spread evenly with a spatula to approximately 0.25 inch thickness.
07 - Drizzle the matcha chocolate over the peppermint layer in diagonal lines or dollops, then gently swirl with a toothpick or skewer to create a decorative marbled pattern.
08 - Immediately sprinkle the crushed peppermint candies evenly over the surface while the chocolate remains soft for proper adhesion.
09 - Refrigerate for 30 minutes or until the bark is completely firm and set to the touch.
10 - Break or cut into 16 pieces and store in an airtight container at cool room temperature or in the refrigerator.
