If you don't know about this classic French cakes, it is called Madeleine cakes and they are actually much like Malay Bahulu cakes. Madeleines are originally from Commercy and Liverdun, two communes of the Lorraine region in northeastern France.
Madeleines are very small sponge cakes with a distinctive shell-like shape acquired from being baked in pans with shell-shaped depressions. Aside from the traditional moulded pan, commonly found in stores specialising in kitchen equipment and even hardware stores, no special tools are required to make madeleines.
A génoise cake batter is used. The flavour is similar to, but somewhat lighter than, sponge cake. Traditional recipes include very finely ground nuts, usually almonds. A variation uses lemon zest, for a pronounced lemony taste.
