The use of a cake base is not strictly necessary, but it is highly advised for most cakes. While smaller cakes might be able to hold their shape without the additional support of a cake board, larger or more intricate designs benefit greatly from having a stable base. A cake base provides an extra layer of protection and support, especially during transportation or when stacking multiple tiers of cakes together. It helps maintain the overall structure of the cake, prevents any sagging or slippage, and allows for cleaner cuts and presentation when serving. Ultimately, using a cake base ensures that your creation remains intact and visually appealing throughout its lifespan from preparation to consumption.
