01 - Line a large baking tray or flat surface with parchment paper to prevent sticking during assembly.
02 - Finely crush the Oreos in a food processor until they resemble fine crumbs. Transfer to a mixing 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. Using a rolling pin, roll out to 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 using an electric mixer until stiff peaks form. Gently fold in food coloring until the cream is evenly tinted orange or purple.
05 - Spread the colored whipped cream evenly over the rolled-out Oreo base, leaving a 1-inch border along one long edge. This border helps seal the roll properly.
06 - Using the parchment paper to guide you, carefully roll the mixture into a tight log starting from the long edge without the border. Roll away from you, applying gentle pressure to keep it compact. Place seam-side down on the prepared tray.
07 - Refrigerate the roll for at least 1 hour, or until firm enough to hold its shape cleanly when sliced.
08 - Drizzle with melted chocolate if desired, then sprinkle generously with Halloween decorations and candy eyes. Slice into 1-inch rounds using a sharp knife, wiping the blade clean between cuts. Serve immediately while cold.
