Who invented the cookie called monster cookie?

There isn't one definitive inventor of the "monster cookie." This is because it's a cookie that has evolved over time, with many variations appearing in different places. Here's why:

* "Monster Cookie" isn't a registered trademark: This means there isn't a single company or individual who owns the name and recipe.

* Variations: The basic idea of a monster cookie (oatmeal cookie with chocolate chips, M&Ms, and other add-ins) has been around for decades. People have been adding their own twists to these cookies for a long time.

* Home-baked tradition: Many families have their own "monster cookie" recipes that have been passed down through generations.

Therefore, it's more likely that the monster cookie evolved from a combination of different influences rather than being invented by a single person.
