Make friends with the freezer
Cake freezes well, particularly when un-iced. Wrap tightly in clingfilm, then again in foil – this will help ensure no moisture gets in, and will protect the cake from freezer burn. Undecorated cakes such as this almond, rosemary and courgette cake are easy to freeze ahead of time, ready for any occasion. Frosted cake can also be frozen: refrigerate first to harden the buttercream, then wrap well as above. Freeze for up to 3 months, then thaw in the fridge before bringing to room temperature.
