ELI5:Why does baking a cookie make it impossible to turn it back into dough?

Mud can be made back into dirt and water, even after being left in the sun. What's so different about cookie dough?

Mud is not a chemical reaction.
It's just adding water to sand. The water creeps between the sand particles making them move around more easily.

The more water the more "fluid" it becomes.


Baking cookies is a chemical reaction where different ingredients bind together which creates new chemicals.

The baking itself removes moisture but also provides the energy (heat) for the chemical reactions.

Reversing the procces isnt possible because the energy is already absorbed.


Think of it like this:

If you take the fuel from a car, the car doesnt reverse to its original position.
