1-Getting started with sheet pan chocolate chip cookies is as easy as preheating your oven. Begin by setting it to 325 degrees Fahrenheit and prepare a standard half sheet pan that’s 13 by 18 inches with nonstick spray to keep things simple. In a large mixing bowl, whisk the melted butter and both sugars until smooth, making sure to break up any clumps in the brown sugar for an even mix.

2-Next, add the eggs, egg yolks, milk, and vanilla, whisking everything until it’s nice and smooth. Then, incorporate the flour, cornstarch, baking soda, baking powder, and salt by folding them in until mostly combined. Gently fold in the chocolate chips to distribute them evenly through the dough.

3-Spread the dough out evenly on your prepared baking sheet, smoothing it for uniform thickness, and sprinkle on extra chocolate chips if you like. Bake for about 22 minutes, keeping in mind to slightly underbake so the cookies stay moist as they cool. Once done, let them cool completely on the pan before cutting into portions for serving.
