The cookie is marketed as the Monaco in Canada; local company Milano Bakeries had established prior rights to the "Milano" brand for cookies sold in that country.
[1][2] The Milano was created as a result of Pepperidge Farm's original cookie concept, the Naples, which was a single vanilla wafer cookie topped with dark chocolate.
Other flavors include a layer of mint, sweet orange paste, dulce de leche and lemon in addition to some form of chocolate.
[3] Pepperidge Farm took legal action against a single company for an alleged attempt to imitate their cookies in 2015.
[4] Milano cookies themselves bear a striking resemblance in taste and composite to langue de chat biscuits found across Europe, Asia, and South America.
