These are some of my favorite cookies. I like to substitute 1/2 the butter with coconut oil for slightly healthier and definitely tastier cookies.

Why do these cookies spread too thin on standard baking sheets? Chemical reactions dictate the final structure of every batch. Granulated white sugar provides crispness through sucrose, while dark or light brown sugar introduces molasses. Molasses is acidic. That acidity reacts with baking soda to release carbon dioxide gas, lifting the dough while retaining moisture due to hygroscopic properties. Butter contains water that converts to steam, widening the spread, whereas coconut oil solidifies at cooler temperatures and alters the melting point of the fat matrix. Substituting a portion of the fat changes how the starches hydrate.
Overmixing activates the protein networks in all-purpose flour, transforming tender cookies into tough discs. Precise timing protects the interior chewiness.
