Preheat oven to 350 degrees. Line cookie sheet with parchment paper or silicone baking mat and set aside.
In a large bowl, cream butters and sugars together. Stir in egg and vanilla and whip until light in color and fluffy, about 2 minutes.
Slowly stir in baking soda, salt, flour and oats until just combined. Stir in chocolate chips by hand.
Using a cookie scoop, create 8 cookie dough balls on your prepared baking sheet. Press dough down flat. Top with a milky way bar and place another scoop of cookie dough over top. Press the dough around the Milky Way bar to enclose/cover completely.
Bake 9-11 minutes or until cookie starts to turn light golden brown on the bottom.
Cool 3-5 minutes before removing to a cooling rack.
