Preheat oven to 475°
Prepare baking sheets with parchment paper to prevent sticking
In the smaller mixing bowl, whisk together the flour, corn starch, salt, and baking soda
Cut the stick of butter into smaller pieces (as seen in the video) (don’t cut them too small or it will melt too much. You want bigger chunks of butter
In the larger mixing bowl, combine the butter, sugar, brown sugar, egg, and vanilla extract. (I use paddle attachment of stand mixer) and slow speed 1 to mix and don’t overmix! Add dry ingredients very soon!
Gently stir the dry ingredients (flour, corn starch, salt, etc.) into the larger bowl with the butter/egg/sugar mixture (as seen in the video)
Add in chocolate chips and optional walnuts. Mix gently until fully combined
Using a full size spoon (tablespoon), make cookie dough balls and place them on the baking sheet
Bake for 6-7 minutes (or even 5 I’ve done … they stiffen more as they sit out of oven) or until the tops of the cookies get golden/brown (keep your eye on them:)
Remove from the oven and let them cool. They’ll continue to cook on the inside while they cool
For the softest cookies, eat them when they are warm, not totally cooled
