7 Golden Rules for Soft & Fluffy Cookies
Forget cakey or rock-hard cookies. Follow these steps for soft, chewy, thick cookies that feel like heaven in every bite.
1. Embrace Brown Sugar (And Use More of It)
Why it works: Brown sugar contains molasses, which attracts and holds moisture. More moisture = softer, chewier cookies that stay tender for days.
Pro tip: Use a higher ratio of brown sugar to white sugar—try 2:1 for maximum softness.
2. Melted Butter is a Game-Changer
Why it works: Creaming solid butter traps air, which can make cookies cakier and cause them to spread too much. Melted butter reduces air pockets, giving cookies a tender, soft crumb.
Pro tip: Melt your butter and let it cool for 10–15 minutes before adding eggs, so you don’t accidentally cook them.
3. The Cornstarch Softness Hack
Why it works: Cornstarch tenderizes dough by limiting gluten development, producing cookies with that thick, bakery-style texture.
Pro tip: Replace 1–2 tablespoons of flour with cornstarch for the perfect soft bite. For example, use 2 ¼ cups flour minus 2 tbsp, plus 2 tbsp cornstarch.
4. Don’t Overmix the Flour
Why it works: Overmixing develops gluten, which makes cookies tough instead of tender.
Pro tip: Fold the flour gently into wet ingredients with a spatula until no streaks remain—no mixer required.
