    Soft, moist and fluffy banana sheet cake with caramel butterscotch buttercream

    If you've got some bananas that are getting way too brown, and you're looking for something a little more than your regular banana bread I've got the recipe for you. This banana cake is soft and fluffy, full of banana flavour, and incredible when topped with a silky butterscotch buttercream. This banana cake is one of my favourite recipes because the texture is just so good...

    Tips to create a fluffy moist cake

    Banana cakes tend to be moist due to the extra moisture from bananas. On the other hand you have to be careful you are not adding too much banana as it can cause the cake to become quite gummy.

    Here are a couple of tricks to making sure your banana cake is the best it can be!

    • Use ripe bananas

    Bananas that are still bright yellow aren't the best for making banana cake. At this stage their flavour hasn't fully developed. They also don't have as much sweetness and moisture as a browned banana. If you use a yellow (or even worse a green) banana in your cake not only will it not have as much flavour it will be significantly drier.

    • Mash your bananas well

    It's important to make sure your bananas are well mashed. If they aren't broken down well enough less moisture is released from the fruit, effecting the texture of your cake. That being said you don't want to blitz it to a banana puree either! A few chunks here and there adds some variety and texture.

    • Don't overmix

    I always say this, but it's so important! Overmixing your batter causes the formation of gluten creating a dense and rubbery cake. Mix until the ingredients are just mixed in.

    Creating a silky butterscotch buttercream

    This buttercream is made of two components caramel and butter. It's similar to the one I made on the pear and caramel cake, but this time instead of boiling down the caramel from poaching liquid (which is extremely time consuming) this is a quick and easy butterscotch. All you need to do is combine the brown sugar, butter and cream together and boil until dissolved and slightly thickened.

    When using the butterscotch in your buttercream it's important that it has cooled completely. If it is even a little warm the resulting buttercream will be very soft and may even curdle.

    Besides using cool butterscotch all you have to do it keep whipping! The longer you keep your butter and caramel in the mixer lighter, fluffier and silkier your buttercream will be.

    To ensure you have a smooth buttercream without air bubbles reduce your mixer down to low speed for the last 3-4 minutes and beat. This removes any air pockets and creates a silky buttercream.

    Frequently asked questions

    What is the difference between banana cake and banana bread?

    Banana cake is a lot lighter and softer, with a tender crumb in comparison to banana bread which has more structure and a denser crumb. Banana cake typically has more sugar, butter and eggs to create that airy cake texture.

    What bananas are best for this cake? Can I use yellow bananas?

    The riper the bananas are the better! We want dark brown spotty bananas as they have the most flavour and moisture. If you only have yellow bananas on hand that's okay too! You can ripen them in the oven before baking. Simply put them in a 150C/300F oven for 30 minutes, then let them cool before mashing.

    How long can I store this cake?

    This cake can be stored at room temperature for 2 days and in the fridge for a week. It's best consumed at room temperature as it allows the buttercream to soften, so take the cake out of the fridge 30-60 minutes before eating.
