I like how you explain exactly what you thought moving forward on the cookie iterations. Plus, it is always interesting to see the steps you took to make the actual cookies. The chronological pictures add a lot to understanding what went well and what went wrong in your iterations. I wish that your pictures for what I assume to be Idea 1 Test were under the header. This way, it would be easier to see what pictures belong to what part of the story. What if your final cookie picture also had a cross sectional view of the chocolate under the marshmallow. This would allow for the reader to better understand what to expect in the cookie prior to reading the rest of your blog.
