01 - Line a large baking tray or flat surface with parchment paper to prevent sticking during assembly.
02 - Crush Oreos in a food processor until finely ground. Transfer to a bowl and add powdered sugar, melted butter, and softened cream cheese. Mix thoroughly until a thick, sticky dough forms.
03 - Place the Oreo mixture between two sheets of parchment paper. Roll into a rectangle approximately 1/2 inch thick, ensuring even thickness throughout.
04 - In a chilled bowl, beat heavy whipping cream with powdered sugar and vanilla extract until stiff peaks form. Gently fold in food coloring until the color is evenly distributed.
05 - Spread the colored whipped cream evenly over the rolled Oreo base, leaving a 1-inch border along one long edge. This border will help seal the roll.
06 - Using the parchment paper for support, carefully roll the mixture into a tight log starting from the long edge without the border. Place seam-side down on the prepared surface.
07 - Refrigerate for at least 1 hour until firm and set. This step is crucial for clean slicing.
08 - Drizzle with melted chocolate and sprinkle with Halloween decorations. Add candy eyes if using. Slice into 1-inch portions with a sharp knife and serve cold.
