Instructions
In a bowl, mix together flour, cornstarch, salt and baking soda. Set aside.
In the bowl of a stand mixer (or using a hand mixer), cream together butter and both sugars on medium speed until light and fluffy (2-3 minutes). With the mixer on low, add in egg and vanilla. Return mixer to medium and mix until incorporated. Scrape sides if needed.
With the mixer on low, add dry ingredient mixture gradually until dough forms. Stir in chocolate chips by hand. Refrigerate dough for at least 30 minutes. Preheat oven to 350ºF and line baking sheets with parchment paper or Silpat, and set aside.
Form balls from approximately 1 tablespoon of dough. Bake for 9-11 minutes or until edges are just barely golden. Remove from oven and let cool for a couple of minutes on baking sheet before removing and placing on wire rack to finish cooling. Store in airtight container.

Notes
If desired, place 2-3 chocolate chips on top of each ball of dough before baking for a pretty appearance.
