Ferrero Duplo Hazelnut Bar

Duplo is a popular hazelnut-filled chocolate bar produced by the Italian confectionery giant Ferrero. Originally launched in Germany in 1964, it has become one of the brand's most recognizable snacks across Europe. The product features a crispy wafer filled with a smooth hazelnut cream and topped with whole hazelnuts, all coated in milk chocolate.

Ferrero, founded by Pietro Ferrero in Alba, Italy, in 1946, remains a private family-owned company. While the brand originated in Germany, the company's global headquarters are located in Luxembourg. Duplo bars are primarily manufactured in Germany at the Ferrero plant in Stadtallendorf, though the company maintains a vast production network internationally to supply different markets.
