Preheat oven to 350-degrees and line a baking sheet with parchment paper or a baking mat.
In an electric mixer bowl, cream butter and sugars, add pudding mix until blended.
Beat in the eggs and vanilla.
In a separate bowl, combine the flour and baking soda with a whisk. Add the dry ingredients to the butter mixture and mix on low until combined. Stir in the Oreo cookie pieces.
Drop cookies by rounded spoonfuls onto the prepared baking sheet. Bake for 10 minutes until cookies tops barely have a touch of brown. (These cookies do not brown up a lot unless overcooked).
