01 - Line a large baking tray or flat surface with parchment paper to create your rolling station.
02 - Process Oreos in a food processor until finely crushed. 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. Roll out to form a rectangle approximately 1/2 inch thick.
04 - In a chilled bowl, beat heavy cream with powdered sugar and vanilla extract using an electric mixer until stiff peaks form. Gently fold in food coloring until the mixture achieves your desired orange or purple tint.
05 - Spread the colored whipped cream evenly over the rolled Oreo base, leaving a 1-inch border on one long side. Starting from the edge without the border, use the parchment paper to carefully roll the mixture into a tight log. Seal the seam side down.
06 - Refrigerate the roll for at least 1 hour or until firm enough to slice cleanly.
07 - Drizzle with melted chocolate and sprinkle with Halloween decorations. Add candy eyes if desired. Slice into 1-inch portions with a sharp knife. Serve cold.
