Place the Oreo cookies into a food processor and pulse until they form fine crumbs.

In a large mixing bowl, combine the cookie crumbs, softened cream cheese, pumpkin puree, and pumpkin pie spice until a uniform dough forms.

Scoop the mixture into 1-inch balls and place them on a parchment-lined baking sheet.

Freeze the balls for 15 minutes to firm up before dipping.

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

Dip each chilled ball into the melted chocolate, tap off excess, and return to the baking sheet. Top with sprinkles immediately before the chocolate sets.
