Why do my cookies go hard? Keep them soft and chewy

Soft, chewy on day one; hard as a hockey puck by day two. Cookies going hard is a storage and baking problem, and both are easy to sort.

1. You baked them a minute too long

Cookies keep cooking on the hot tray after they leave the oven. Bake until the edges are set but the centres still look slightly underdone — they firm up as they cool.

The fix: pull them when the middles look barely done. If they're golden all over in the oven, they'll be hard once cool.

2. Too much flour, not enough fat or sugar

Brown sugar in particular holds moisture and keeps cookies chewy; a recipe heavy on flour and light on butter bakes crisp and hardens fast.

The fix: use a recipe built for chewy cookies (more brown sugar, a touch more fat) and weigh your flour so you're not accidentally adding extra.

3. They were stored wrong

Left open to the air, cookies stale and harden within a day.

The fix: store in an airtight tin. Drop in a slice of soft bread — the cookies pull moisture from it and stay soft for days. Swap the bread when it dries out.

4. Freeze the dough, not the cookies

Baked cookies stale; raw dough freezes beautifully.

The fix: roll dough into balls and freeze them, then bake a couple fresh whenever you want — soft every time, no waste.

The honest summary

Underbake very slightly, use a chewy-style recipe with brown sugar, and store airtight with a slice of bread. That's soft cookies for days.
