Ensure that butter and eggs are at room temperature for smoother mixing. If needed, place cold eggs in a bowl of warm water to quickly bring them to room temperature. Using a cookie scoop will yield uniform cookies for consistent baking. Measure flour precisely to avoid dry cookies—ideally with a digital kitchen scale or by fluffing the flour, spooning it into the cup, and leveling with a knife. For a tender texture, do not rush the creaming process; thoroughly blending the butter and sugar helps aerate the dough, resulting in lighter cookies. It is normal for the centers to appear slightly underbaked when removing them from the oven—they will set as they cool.
