The Sweet Science Explained
Knowing a bit about what's happening when you make these treats can help you nail the texture every time. The corn syrup gives that shiny finish and stops sugar from forming crystals, which keeps them perfectly crisp-chewy instead of gritty. When you heat everything up, sugar molecules connect with peanut butter oils to create that magic coating that wraps each cornflake just right. You want to hit around 235-240°F, though you don't need fancy tools. The mix should coat the back of your spoon and make a soft thread when you lift it up. That's when you know it's cookie time.

Common Problems Solved
Got cookies that are too hard? You probably heated the mix too much. Not setting properly? You didn't heat it enough. You want to aim for when tiny bubbles just start appearing around your pan's edge.
Keeping Them Fresh
Store your treats in something airtight and they'll stay crunchy for about 5 days. That's if they don't vanish before then! Put some wax paper between layers so they don't stick together.
