No-Bake Cookies problems, diagnosed

Start with the cooked sugar mixture. King Arthur's no-bake cookie recipe boils the base for 1 minute and gives a measurable target of 215°F to 220°F before the nut butter and oats go in. Food Network also uses a full boil before the cookies are dropped and cooled. If the cookies stay loose, check boil stage, ingredient ratios, mixture thickness before scooping and whether they were given enough cooling time.
