Storage Tips
Wrap leftover cake tightly in plastic wrap or place in an airtight container to keep it moist in the fridge for up to five days or freeze for up to three months allowing it to thaw at room temperature before serving.
For best texture frost only after the cake has completely cooled to prevent melting.
