Bunchosia glandulifera, commonly known as peanut butter fruit, is a species of flowering plant in the acerola family, Malpighiaceae, that is native to Central America and South America. It produces small orange-red fruits of sticky and dense pulp, with a flavour and aroma resembling that of peanut butter. It is mostly eaten fresh, but is also used for jellies, jams or preserves. The superficial appearance of the berries are similar to coffee and in Brazil is accordingly called caferana or falso guarana.

Bunchosia glandulifera has been introduced to the U.S. horticulture as Bunchosia argentea and was further distributed under this name.
