Crush the Oreo cookies finely in a food processor or by hand, including the cream filling.
In a large bowl, mix the crushed cookies with softened cream cheese and pumpkin pie spice until combined into a thick dough.
Chill the mixture in the refrigerator for 30 minutes to 1 hour until firm.
Roll the chilled mixture into 1 to 1.5-inch balls and place them on parchment-lined baking sheets.
Refrigerate for another 15-20 minutes to firm up further.
Melt the orange candy melts according to package instructions and dip each ball into the melted coating, letting excess drip off before placing back on sheets.
Allow to set at room temperature for about 10-15 minutes and then chill again for 30 minutes until completely set.
