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 white chocolate and stir constantly until completely smooth and melted.
03 - Remove approximately half of the melted white chocolate to a separate clean bowl, leaving equal portions in both bowls.
04 - Sift the matcha powder into one bowl of melted chocolate. Stir thoroughly until fully incorporated and the mixture achieves a vibrant green color.
05 - Add the peppermint extract to the remaining bowl of white chocolate. Mix well to distribute the flavor evenly.
06 - Pour the peppermint-infused white chocolate onto the prepared parchment-lined baking sheet. Use a spatula to spread it evenly to approximately 1/4 inch thickness.
07 - 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 swirled marbled pattern.
08 - Immediately sprinkle the crushed peppermint candies evenly over the surface while the chocolate remains soft to ensure proper adhesion.
09 - Transfer the baking sheet to the refrigerator and chill for 30 minutes or until the bark is completely firm and set.
10 - Break or cut the chilled bark into 16 pieces. Store in an airtight container at cool room temperature or refrigerate for longer shelf life.
