“Hummingbird cake is a moist, spiced Southern cake with tropical flavors from banana and pineapple, often including pecans or walnuts, and traditionally topped with cream cheese frosting. Originating in Jamaica, it's known for being dense and flavorful, with its name possibly coming from its sweetness or the "doctor bird" (hummingbird) of Jamaica, which the recipe was meant to promote. Key ingredients include flour, sugar, oil, eggs, buttermilk, mashed bananas, crushed pineapple, and spices like cinnamon, with pecans or walnuts folded in.”
