The Sweet Chemistry Explained
Knowing what's happening behind the scenes can help you nail these treats every time. The corn syrup gives that awesome shine while stopping sugar from forming crystals - that's why you get that perfect chewy-crunchy bite instead of a gritty texture. When you heat everything up, sugar molecules join with peanut butter's natural fats, creating that magical stuff that sticks to each cornflake perfectly. You want to hit about 235-240°F (no thermometer needed though). At this point, the mix will stick to the back of your spoon and make a little thread when dripped - that's when you know it'll make perfect cookies.

Fixing Common Problems
If your cookies turn out too firm, you probably overheated the mixture. If they won't set up properly, you didn't heat it enough. You'll know you've got it right when tiny bubbles just start forming around your pan's edge.
Keeping Them Fresh
Store these goodies in something airtight and they'll stay crunchy for about 5 days - assuming they don't vanish before then! Put some wax paper between layers so they don't stick together.
