Step 1: Prepare Your Baking Sheet - Line a baking sheet with parchment paper, ensuring it covers the entire surface for easy lifting.
Step 2: Crush the Oreos - Crush the Oreo cookies into smaller chunks using a rolling pin or food processor, but avoid turning them into dust.
Step 3: Melt the Chocolate - In a microwave-safe bowl, combine white chocolate chips and vegetable shortening. Microwave in 30-second intervals, stirring until smooth.
Step 4: Combine and Spread - Fold in the crushed Oreos into the melted chocolate, pour onto the prepared baking sheet, and spread evenly with a spatula.
Step 5: Chill and Set - Refrigerate for 1-2 hours or let it set at room temperature until completely hardened.
Step 6: Break and Enjoy - Once set, lift the bark from the parchment paper and break it into pieces. Serve or store for later.
