What kind of cookie is used to make a Cool A Coo?

Question

I need help settleing a bet. Cool A Coos are the ice cream sandwiches, that were dipped in chocolate, they used to sell at Dodger games. The bet is what type of cookie is used.

Answer 1

Well they used to have It's It ice cream sandwiches at Dodger Stadium and I will never forgive taking them away.  They used oatmeal cookies which made them special.  I think they are the same thing/used to be called Cool a Coos.
