If you do not have mini loaf tins, bake the financiers in two 12-cup muffin tins. In this case, place 2 tbsp (30 ml) of batter into each cavity and reduce the cooking time by 2 to 3 minutes.
Garnish your financiers with berries only if you plan to serve them the same day you bake them. If you are preparing your cakes in advance, omit the fruit garnish.
If you freeze the financiers, reheat them in the oven for a few minutes before serving to bring back the classic crunch to the exterior.
