Instructions

• Preheat the oven to 350 degrees F and line baking sheets with parchment paper.
• Place the butter and sugar in a large mixing bowl and beat on medium-high speed until very pale and fluffy (about 3 to 5 minutes).
• Add the egg, and beat on medium-high speed until incorporated.
• Stir in the egg yolk and vanilla extract until combined.
• Scrape the bottom and sides of the bowl with a silicone spatula, then add the flour, cornstarch, baking soda, and salt.
• Stir together until incorporated.
• Use a 1.5-tablespoon cookie scoop to drop balls of cookie dough on the prepared baking sheets, allowing two inches in between for spreading.
• Flatten the balls slightly with the palm of your hand.
• Bake the cookies (one sheet at a time) in the center rack of the oven for 8 to 12 minutes, or until the edges are set and just barely beginning to turn golden. (Take care not to over-bake, or the cookies will not be as soft.)
• Cool on the baking sheet and transfer to an airtight container for storage.
