I like how you pondered what a cookie is, and came to the realization that an innovative cookie doesn’t have to be revolutionary new. And how you talked about your idea being like a monster cookie of sorts, but having it be different and innovative.
I wish that you could have some more pictures to help enhance your explanations of the two cookie ideas you tried. While you did a great job writing about the process of stuffing the cookie dough in a different cookie dough, it would have been nice to visually see that process.
What if you swirled the three doughs together for your last cookie like a marble cake. I know you initially had troubles with having the cookies staying together initially and in transport, maybe by swirling them together they would bake well together. And you still get all the combinations of flavors, and every bite would be different from the previous.
