LU Petit Ecolier chocolate biscuits

LU, which stands for Lefèvre-Utile, is an iconic French brand of biscuits founded in Nantes in 1846 by Jean-Romain Lefèvre and Pauline-Isabelle Utile. The brand is globally recognized for its Petit-Beurre biscuits and the Petit Ecolier range, which features a thick layer of chocolate embossed with the image of a 'little schoolboy'.

While the brand's heart remains in France, manufacturing today occurs in multiple locations across Europe and globally to serve international markets. Since its inception as a small family-run bakery, LU has undergone several changes in ownership. It was part of Danone for several decades before being acquired by Mondelēz International. As of 2026, LU remains a flagship brand under the Mondelēz portfolio, benefiting from their massive global distribution network.
