Prepare Your Work Area : Line a baking sheet with parchment paper or a silicone mat to prevent sticking.

Melt the White Chocolate : In a microwave-safe bowl, melt the white chocolate chips in 20–30 second intervals, stirring after each interval until smooth. Alternatively, melt the chocolate using a double boiler over low heat, stirring continuously.

Combine and Spread : Once melted, pour the white chocolate onto the prepared baking sheet and spread it evenly using a spatula, creating a thin layer.

Add Toppings : Immediately sprinkle the chopped cranberries and pistachios evenly over the melted chocolate. Press lightly to ensure they adhere.

Set and Break : Let the bark cool and harden completely. You can speed up the process by placing the tray in the refrigerator for 20–30 minutes. Once set, break the bark into irregular pieces by hand or use a knife for cleaner edges.
