There is a slight difference in taste is a candy bar (or ‘chocolate bar’ as we prefer to call them in Canada) produced by The Hershey Company. The Skor bar consists of a thin slab of butter toffee covered in a milk chocolate coating, but is slightly thinner than the Heath bar. The Heath bar calls itself an “English Toffee Bar" while the Skor is more of a “Crisp Butter Toffee.”
