For optimal texture, ensure your butter is truly softened to room temperature for proper creaming with the sugars and peanut butter, leading to a lighter cookie. Avoid overmixing the dry ingredients once added, as this can develop gluten and result in tougher cookies. The 'dry on top' indicator for doneness is key; cookies will continue to set as they cool, so pulling them out when just dry on top will prevent them from becoming too hard. For an enhanced flavor and textural contrast, consider using a good quality, natural creamy peanut butter and optionally adding a tablespoon of finely chopped roasted peanuts to the dough with the chips. The crosshatch pattern isn't just for aesthetics; it helps flatten the cookie for more even baking.
