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 stick of butter into smaller pieces (as seen in the video)
In the larger mixing bowl, combine the butter, sugar, brown sugar, egg, and vanilla extract
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 until the tops of the cookies get golden/brown (keep you 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
