Preheat the oven to 350 degrees. Line a large baking sheet with parchment paper or a silicone baking mat.
In a large bowl, add the cake mix oil, and eggs. Mix until fully combined. Add in the crushed oreos, and white chocolate chips and fold them into the dough until combined.
Scoop about two tablespoons of dough and roll it into a ball. Place the dough onto the baking sheet and bake for 12-13 minutes.
Take the cookies out the oven and allow them to cool for 5 minutes on the baking sheet. Transfer them to a wire rack to finish cooling then store in an airtight container.
