I added approximately 3 tablespoons of milk to the batter to make it form cohesive logs and I would recommend adding a bit more mint extract (perhaps to the chocolate coating) to make the mint flavor more prominent. I'd make a recommendation for my biggest issue with the cookies but I have no ideas... The chocolate coating never hardened!
I let the cookies cool completely prior to coating them in the chocolate/butter mixture and ultimately let them sit overnight with wax paper over them. In the morning? They were still soft. I ended up putting wax paper pieces between each one to prevent a mess and ultimately suggesting that Danielle keep them in the fridge, which isn't so bad as Thin Mints always taste good cold.
These were fun to try but I don't think they are worth the effort involved. I'll probably stick to supporting the Girls Scouts (or stealing cookies from others who support the Girls Scouts) when I want Thin Mints in the future. If you live nearby feel free to arrange a visit for a frozen cookie or two in the next few weeks... I have extras in my freezer.
