The Chemistry of Baking Delicious Cookies

Stephanie Warren of Test Tube Kitchen explains the chemistry behind baking delicious cookies in this TED-Ed animation by Brooklyn-based Augenblick Studios.

You stick cookie dough into an oven, and magically, you get a plate of warm, gooey cookies. Except it’s not magic; it’s science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we can kill salmonella, and why that intoxicating smell wafting from your oven indicates that the cookies are ready for eating.
