are jaffa cakes a biscuit or a cake
Jaffa Cakes Jaffa Cakes are biscuit-sized cakes introduced by McVitie and Price in the UK in 1927 and named after Jaffa oranges. The most common form of Jaffa Cakes are circular, 2 1⁄8 inches (54 mm) in diameter and have three layers: a Genoise sponge base, a layer of orange flavoured jam and a coating of chocolate.[1] Jaffa Cakes are also available as bars or in small packs, and in larger and smaller sizes.[2] The original Jaffa Cakes come in packs of 12, 24 or 36.[3]
Devil's food cake Devil's food cake is a moist, airy, rich chocolate layer cake. It is considered a counterpart to the white or yellow angel food cake. Because of differing recipes and changing ingredient availability over the course of the 20th century, it is difficult to precisely qualify what distinguishes devil's food from the more standard chocolate cake, though it traditionally has more chocolate than a regular chocolate cake, making it darker. The cake is usually paired with a rich chocolate frosting.
