Which bananas are best to use
I recommend very ripe bananas for the cake batter because they add extra flavor and sweetness to the cake. For the halved bananas on top of the cake, however, I recommend barely ripe bananas. The bananas you use for the top shouldn't be covered in black dots and shouldn't smell fermented (like alcohol) as that would compromise the flavor of this dessert.

How to prevent the pan from leaking
To prevent leaking of the syrup while baking, tightly wrap the outside of the springform pan in aluminum foil, just as you would when preparing a cheesecake to bake in a water bath.
Make this cake without rum
- Topping - This bananas foster upside down cake is made with rum, but you can also make it without rum. Therefore, replace the rum 1:1 with water for the sauce. If you want to add some rum flavor to the sauce, replace the rum with 3 tablespoon water (45ml) and 1 tablespoon (15ml) rum extract.
- Cake batter - You can either substitute 1 teaspoon of rum extract for the rum in the cake batter, or leave it out.
Store, reheat and freeze
- Store the cake in an airtight container in the fridge for up to 2 days. Let come to room temperature before serving.
- Reheat this bananas foster cake in the microwave for 20-30 seconds.
- After the cake has cooled completely, flash freeze the cake in the pan for 1-2 hours. Then cut into individual slices, wrap tightly in foil, and store in freezer bags. Thaw on the kitchen counter for 1-2 hours before serving.

- Melt the butter in a medium saucepan over medium heat. Add the brown sugar, vanilla, cinnamon, and rum and bring to a simmer. Stir regularly. Cook until the mixture thickens and coats the back of a spoon, about 2-3 minutes. Then pour the sauce evenly over the bananas and set aside.
