In addition to Barbie chocolates and Barbies dressed as chocolate, I'm sure it comes as no surprise that Barbie sells chocolate.
As part of a branded collaboration with hot cocoa company Swiss Miss (back in the days where a lot of Barbie releases had incidental branded products), the Barbie Chocolate Shop hit shelves in 1991.
This particular ad (which spells the product as "Shoppe") provides more details about how the product serves both as a cafe setting for Barbie and Ken to spend a romantic date together and a place to create hot chocolate or melt chocolate chips into candy treats.
It is worth noting that this was part of a wider ski themed release - the Barbie and Ken here are Ski Fun Barbie and Ken.
Surprisingly, there's remarkably few other Barbies as chocolate saleswomen - a plethora of pastry chefs and bakers, but very few themed specifically around chocolate.
Although there definitely appear to be some chocolate elements. (And an animal. In the kitchen. This Barbie violates the health code!)
And speaking of animals and chocolate... I do have to draw attention to another Barbie product that came up in my search because I feel like the branding is... off somehow.
Why would you theme a set with "milk chocolate treats" around a VET?! That seems like it is setting a dangerous precedent! Is that how Vet Barbie makes her money?!
