Squirrels with vanilla oreos?

Ok, so I moved to WI about 2 years ago and Immediately noticed that the squirrels in our neighborhood always had vanilla oreos, then they started leaving them at my door... I was giving them like peanuts and they would leave the oreos in return. Has anyone else noticed this? 😂 Is someone feeding the squirrel oreos?

Also I finally got a picture 👇
