Mix the dry ingredients: In a bowl, whisk together both flours, salt, cornstarch and baking soda.
Mix the wet ingredients:Set up an electric mixer with the paddle attachment.Add butter (microwave it for 15 seconds if not kept at room temperature) followed by both sugars.Beat on medium speed until light and fluffy. Stop and scrape as needed. Reduce speed to low; add eggs (one at a time) and beat till they are combined. Add vanilla and mix well
Mix the wet and dry ingredients:Add the flour mixture and mix until they are combined (don't overdo it - maybe for a minute. The mixture should not be extremely sticky, should be almost dough like but slightly sticky. Add flour as needed to get the consistency right).Add the chocolate chips and mix them for 15 seconds. You are ready to bake.
Get ready to bake: Line a cookie baking sheet with parchment paper;Use an ice-cream spoon to scoop cookie dough and place them around 2 inches apart on the baking sheet. Bake for 10-12 minutes until the cookies start to brown lightly around the edges (Ovens differ - so start checking on the cookies around 8 minutes)
Cool down process: Remove the cookies from the oven;wait for couple of minutes and then transfer to a wire rack and let them cool completely (approximately 5-6 minutes) before chomping them down :)
