1. Preheat oven to 350 degrees F.

2. In large bowl, cream together butter, light brown sugar, and granulated sugar for 2 minutes on medium speed. Add in eggs and vanilla bean paste and beat until smooth, about 30 seconds.

3. In a separate bowl, stir together salt, baking soda, cornstarch, baking powder and flour. Gradually add into butter/sugar/egg mixture and mix until just combined.

4. Stir in white chocolate chunks and Oreo pieces.

5. Scoop dough into balls using a cookie scoop and place 2" apart on parchment-lined baking sheets. Bake for 8 to 10 minutes, or until edges are just beginning to turn golden. Remove from oven and cool for 10 minutes on cookie sheets, then move to wire racks to cool completely.
