Adding an extra egg yolk to cookies makes them richer, chewier, and more tender by increasing fat and moisture, creating a denser, fudgier center with less spread, and improving flavor, but too many can make them cakey.

Is it better to bake cookies at 350 or 375?

Baking cookies at 350°F generally yields a classic, slightly crisp edge with a soft center, while 375°F sets the outside faster, resulting in a thicker cookie with a chewier or crispier exterior and potentially underbaked middle, though it can be great for specific textures like chewy edges if done right. Higher temps (375°) mean less spread and more browning, while lower temps (350°) allow more spread and even cooking, making 350° a reliable default for balanced texture.
