01 - Line a large baking sheet with parchment paper and set aside for later use.
02 - Place Oreo cookies (cream filling intact) into a food processor. Pulse in short bursts until cookies are reduced to fine, uniform crumbs resembling wet sand.
03 - Add softened cream cheese to the cookie crumbs. Process until mixture is thoroughly combined and forms a thick, pliable dough that holds together when pressed.
04 - Scoop approximately 1 tablespoon of dough and roll between palms to form an oval egg shape. Place shaped eggs on the prepared baking sheet. Repeat until all dough is used.
05 - Transfer baking sheet to the freezer. Chill for 30 minutes or until eggs are firm to the touch and hold their shape well.
06 - Place chocolate in a microwave-safe bowl. Microwave in 20-second intervals, stirring thoroughly between each, until completely smooth and fluid. Be careful not to overheat.
07 - Working quickly, insert a fork into the bottom of a chilled egg and dip into melted chocolate. Gently tap fork against bowl edge to remove excess coating. Return to baking sheet. Repeat with remaining eggs.
08 - While chocolate coating remains tacky, drizzle with colored candy melts or immediately sprinkle with decorations of your choice. Work in small batches to ensure toppings adhere properly.
09 - Refrigerate decorated eggs for at least 15 minutes until chocolate coating is completely set. Serve chilled or allow to come to room temperature for 15 minutes before serving.
