How long does this cake last for and how should it be stored?This cake will last for up to a week stored in an airtight container.❄️ Suitable for freezingThis cake is also suitable for freezing, either just the sponges or the buttercreamed cake (minus any sprinkles).To freeze just the sponges, I recommend wrapping them in clingfilm to protect them and then freezing.To freeze the finished cake, either:Pop it into a freezer-safe airtight container orPut it into the freezer uncovered for a couple of hours (until the buttercream is firm) and then wrap the cake in clingfilm.If you take the second approach, I’d recommend removing the clingfilm before the cake has defrosted as that’ll help to keep your buttercream neat.I would recommend eating this cake when it’s freshly made rather than freezing it. It freezes well, but we found the chocolate chips were a bit firmer after it had been defrosted and preferred the texture before freezing.
