A palmier (/ˈpælmieɪ/, from French, short for feuille de palmier 'palm tree leaf'), pig's ear,[1] palm heart, or elephant ear[2] is a French pastry in a palm leaf shape or a butterfly shape, sometimes called palm leaves, cœur de France, French hearts, shoe-soles, or glasses, that were invented in the beginning of the 20th century.

The pastries are known as palmeras ("palm trees") in Spain, and they can be topped with coconut or chocolate; they are also available for purchase in a larger version.

In Argentina and Chile, they are known as palmeritas, derivative from the Spanish denomination.

In the United States, desserts similar to palmiers known as pastry hearts are popular in Buffalo.

In Germany they are Schweineohren ("pig's ears"); in Italy Prussiane (derisively after the ostensibly large ears of Prussian invaders) or, more often, ventagli / ventagliette "fan" / "little fans"; in Switzerland Prussiens or cœur de France.
