What chemical reaction do cookies make?

Answer 1

Many chemical reactions take place but the most noticeable one is the maillard browning reaction. The amino acids from the eggs combine with the reducing sugars when baked in the oven to produce melanoidins which are a brown pigment.

Another important reaction occurs due to the baking soda (sodium bicarbonate). When the cookies are baked the baking soda reacts with an acid ingredient to produce carbon dioxide, water and a sodium salt. The carbon dioxide causes the cookies to rise which is why this reaction is important.

Answer 2

Cookies undergo a series of chemical reactions when baked. The heat causes ingredients like sugars and proteins to react, resulting in Maillard browning, caramelization of sugars, and the release of carbon dioxide from leavening agents, causing the cookies to rise and develop their characteristic flavor and texture.
