Bananas Foster cake will stay fresh for up to 5 days in the refrigerator.
The bananas inside will not turn brown since air is what causes oxidation, but once the cake is cut the exposed banana filling may turn slightly. Use a piece of plastic wrap or parchment paper pressed directly against the cut side to prevent severe browning of the filling and drying of the cut cake.
Baked cake layers can be frozen for up to 1 month wrapped well
