Place the Oreo cookies in a food processor and pulse until fine crumbs.

Combine cookie crumbs with softened cream cheese in a mixing bowl. Mix until smooth and well-blended.

Using a tablespoon or small cookie scoop, portion out the mixture and roll into approximately 1-inch balls, shaping them into ghost figures if desired.

Chill the truffles in the refrigerator for about 15 minutes.

Melt the white chocolate in a microwave-safe bowl in 20-30 second intervals until smooth.

Dip each truffle in the melted chocolate, covering fully and shaking off excess.

Before chocolate sets, add sprinkles or edible eyes for decoration.

Allow truffles to set at room temperature for 30 minutes or refrigerate for 10-15 minutes.
