Naked orange poppy seed cake with orange blossom frosting

This pretty cake, with its heavenly orange blossom-scented frosting, is currently one of my favourite ‘special occasion’ cakes – particularly for birthday celebrations. The cake layers are baked in two batches but if you are lucky enough to have four cake pans that can fit in your oven all at once, feel free to make the mixture in one lot and bake them all together.
