Classic French Financier

Delicious french financiers are beautiful cake bars in the shape of ingots, supposed to resemble bars of gold!
Well, they are gold...en brown bars of goodness! If you are a macaron fan and a madeleine fan then this is gonna blow your mind!
Delicious almond flavour enhanced by my personal touch, brown butter. They are so airy and delicious, a perfect afternoon tea pastry!

My mould is specific for making financiers, the shape is a 9,8 x 4,8 cm rectangle, this one is very similar: (paid links)
