Story Synopsis

Cookie dough looks soft and sticky, but it can become crisp and golden. This story explains how that change happens.

In One Glance

Baking transforms dough through heat. Butter melts, helping the dough spread; sugars dissolve and can brown for flavor; proteins in eggs and flour set to hold shape; and water evaporates as steam. As moisture decreases, the cookie becomes firmer. Cooling finishes the process, letting the structure settle. The story frames this as cozy ‘kitchen chemistry’ that kids can imagine step by step.
