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]
Birthday cake The birthday cake is often decorated with small candles, secured with special holders or simply pressed down into the cake. The cake can also be served with other sweets such as ice cream. In the UK, North America and Australia, the number of candles is equal to the age of the individual whose birthday it is, sometimes with one extra for luck. Traditionally, the person whose birthday it is makes a wish, which is thought to come true if all the candles are extinguished in a single breath.
