1Preheat oven to 325 degrees. Grease or line your cookie sheets with parchment paper.
2Sift flour, salt and baking soda together and set aside.
Mix the sugars and melted butter just until thoroughly mixed. Then add whole egg, yolk, and vanilla; mix until creamy. Add the sifted, dry ingredients and mix until just blended - don't over beat.
3Stir in the chunky oreos, chocolate chips, and white chocolate chips by hand. Drop tablespoonsful of dough onto a greased or lined cookie sheet.
4Bake for 10-12 minutes, depending on size of cookies. The edges of cookies should just start to be turning golden brown.
5Leave on cookie sheet for 5 minutes when removed from oven (this is important; as the cookies will fall apart if you move them too quickly). Remove the cookies to a cooling rack to cook completely. Makes approximately 15-20 cookies.
