Plain sponge cake in a very small amount is low risk, but cake is one of the highest-risk categories here because of what's commonly baked into or on top of it — chocolate, raisins, and xylitol-sweetened icing are all common.
There's no single answer for 'cake' because the risk depends entirely on what's in it. Chocolate cake contains theobromine. Fruit cake and some carrot cakes contain raisins or sultanas. Sugar-free or diet cakes and some icings increasingly use xylitol. This is a food where the label matters far more than the base ingredient.
