The Girl Scouts and Costco are teaming for a treat that is going to dominate. They’ve dropped Girl Scouts Thin Mints Mini Bars in stores. Food blogger Markie Devo unveiled the treat with a social media post featuring a snap of the mini bars and a caption saying "The Scouts are definitely planning world domination at this point.” If you love Girls Scout cookies there are other products out there and one is a frozen treat. Girl Scouts Thin Mints Ice Cream Cookie Sandwiches feature peppermint ice cream sandwiched between two chocolate mint cookies and an outer coating of chocolate chips.
