Firm dough
One of the reasons for chilling your dough is that having used soft butter also means that your dough is quite soft. It will be stickier because of this and if you want to use it right away the cookies will expand and spread a lot more. So let’s say you are trying to make cute Christmas cookies and have used a cookie cutter. You want the shape of those cookies to stay intact, but baking the cookies right away will probably make the shapes less pronounced.
Once the dough is chilled (and the butter is once again cold butter) it is much firmer and will be less likely to ruin the shape of your cookies. You will have less spread of the cookie dough. This also depends on the recipe you use, I have a special cut out sugar cookie recipe for perfectly shaped cookies!
Now if you take your dough from the fridge after the chill time, it might still be too hard to roll out. It will crack and crumble. So when I take the cold dough out of the fridge I quickly and briefly knead it by hand before rolling it out and place the cookies on the baking sheet. The short kneading is enough to make the dough pliable again.
Tastier cookies
Yes, chilling your dough also means your cookies will have a better flavor! Cookies and shortcrust pastry actually taste better if you leave the dough in the fridge. The flavors will be absorbed and the final cookies and crusts will have a better texture. If that is not enough reason to give your dough time to chill!
The longer the dough is left in the fridge, the better the result. Personally, I like to make the dough the day before when I make cookies with spices. That way I know the dough has had a sufficient chilling time. Especially with gingerbread or speculaas, the flavor is so much better. You can even freeze most cookie doughs. Obviously frozen dough needs to defrost first, but it’s the ideal way to always have delicious baked cookies in no time at all.
Relaxed gluten = crispy cookies
Do you have a love for crispy cookies? Then make sure you let them cool. It will make a huge difference. Most cookies contain gluten, which makes them tougher. But when you let the dough rest, the gluten relaxes. Relaxed gluten makes for crispy cookies. And we all want delicious chewy cookies with lovely crispy edges right?
So as you can see, for the best cookies you just need to have a little patience and give the dough enough resting time. You will be rewarded with a delicious cookie.
