Preheat oven to 350 degrees.  Line a 9x9 baking pan with parchment paper and spray with nonstick spray.

In a medium bowl, whisk together flour, baking soda and salt.  Set aside.  In a stand mixer, on medium-high speed, cream together butter, sugar and brown sugar until fluffy and light in color.  Add egg and vanilla and mix to combine.  

Turn mixer to low, and slowly add in dry flour mixture.  Mix until combined.  Add in chocolate chips and mix on low speed, until combined.  Do not overmix.

Press ⅔ of chocolate chip cookie mixture in bottom of prepared pan.

In stand mixer, mix together the filling ingredients (cream cheese, sugar, egg, vanilla) until well incorporated.

Pour all of filling on top of chocolate chip cookie mixture.  Place remaining chocolate chip cookie dough in chunks over the top of filling mixture.  Cover evenly.

Bake in preheated oven for approximately 40 minutes or until cheesecake is fully cooked and chocolate chip cookie crust is browned.  Cool completely, then chill in your fridge.  SO GOOD!  Enjoy!
