eli5: why isn’t it possible to cook e.g. cookies at twice the temperature for half the time? obviously i know it isn’t possible, but *why*? what’s the physics behind it?

This reminds of this Disney movie where these characters were prepping for a cooking show competition and one of the dudes tried to bake the cookies in half the time by increasing the temp and ended up burning them. Don’t remember what it was called though.
Heat needs time to spread from the surface to the core of something, if you make the temperature too high the outside will burn before the middle gets to cook
Well, double of 300° degrees isn’t 600° degrees, but 1060° degrees. Thats because absolute zero is -460 degrees. I imagine your cookies would be vaporized in a fraction of a second at 1060 degrees.
Those are Fahrenheit. Celsius equivalents are 150° doubled is really 573°.
Heat conduction. Every material, in this case dough, has a different rate at which it can transport heat, in this case into the inside of your cookie. If you have more incoming heat at the surface than the dough can conduct you get more browning/burning. The correct cooking temperature for pretty much anything is finding a balance between getting it hot enough in the center, while you don’t burn the outside too much.
