I’ve heard that resting cookie dough in the fridge overnight can improve flavor and texture, but I’m not sure why. Does anyone know the science behind it? Is it really worth the wait?

Yes, resting cookie dough overnight can make a big difference! The science behind it involves the process of hydration and flavor development. When the dough rests, the flour absorbs more moisture, which helps create a better texture—cookies often turn out chewier and less crumbly.
