Bahlsen: The Story Behind the Leibniz Biscuit

Few biscuits are as instantly recognizable as the rectangular Leibniz butter biscuit, with its neat lettering and fifty-two “teeth” around the edge. Behind that familiar shape is the story of Bahlsen, a Hanover family business that helped turn biscuits from an occasional luxury into an everyday German favorite.

Hermann Bahlsen starts baking in Hanover

In 1889, Hermann Bahlsen took over a small “cakes and biscuits” operation on Friesenstrasse in Hanover and renamed it the Hannoversche Cakesfabrik H. Bahlsen. Two years later, he introduced the biscuit now known as Leibniz.

The name honored Gottfried Wilhelm Leibniz, the mathematician, philosopher and polymath closely associated with Hanover. Calling the product “Leibniz Cakes” gave the new biscuit a local identity and a name that was both cultured and memorable.

A biscuit made for modern life

Leibniz biscuits arrived at the right moment. Industrial baking and protective packaging made it possible to produce a consistent, crisp butter biscuit that traveled well and could be kept on hand for coffee breaks, school snacks and journeys.

Bahlsen also understood branding early. The company used distinctive packaging and prominent advertising, helping the biscuit become more than a recipe: it became a recognizable part of everyday life.

From Kaffeezeit to chocolate-covered treats

The classic butter biscuit is simple enough for tea or coffee, yet sturdy enough for desserts. Use crushed Leibniz biscuits for a cheesecake base, layer them into an icebox cake or serve them with fruit preserves.

Bahlsen later expanded the idea with chocolate-topped Choco Leibniz, filled Hit cookies, delicate wafer rolls and layered wafer confections. Shop Bahlsen cookies at European Deli to build a German Kaffeezeit assortment.

More than 130 years in the baking

Bahlsen’s lasting appeal comes from combining a clear identity with an uncomplicated pleasure: a crisp biscuit made to accompany a break in the day. Explore the company timeline on Bahlsen’s official history page and the product story on the official Leibniz site.
