These no-bake peppermint bark bars are a festive, easy-to-make holiday treat with layers of rich dark chocolate and creamy white chocolate swirled with refreshing peppermint. They're perfect for gifting or as a cool, refreshing dessert that sets quickly in the refrigerator.
Storage: Keep bars in an airtight container in the refrigerator for up to 2 weeks, or freeze for up to 3 months. Separate layers with parchment paper to prevent sticking. Make-ahead: The bark can be made and refrigerated up to 5 days before cutting and serving. Substitutions: Use semi-sweet chocolate instead of dark chocolate if preferred. For a dairy-free version, ensure chocolate chips are dairy-free. Serving: Let bars sit at room temperature for 5 minutes before serving for best texture.
