Whisk the flour, baking soda, and salt together in a medium bowl; set aside.
Either by hand or with an electric mixer, mix the butter and sugars until thoroughly blended. Beat in the egg, yolk, and vanilla until combined. Add the dry ingredients and beat at low speed just until combined. Stir in the chips to taste.
For crust
Preheat oven to 350.
Press half of the dough onto the bottom of a greased 8-in. square baking pan.
In a large bowl, beat the cream cheese, sugar and egg until smooth. Spread over crust. Crumble remaining dough over top. Bake for 30-35 minutes or until lightly browned and looks set.
