A deliciously tasty banana traybake cake with cream cheese frosting and walnuts – simple and heavenly! 

So we are able to all settle down now okay?! I’ve introduced you a banana cake to finish all banana truffles – this scrumptious banana traybake cake. I’ve had countless quantities of requests for a banana associated cake and extra so a traybake – SO HERE YOU GO! 

Traybake Muffins

Now I do know the phrase traybake can confuse some folks on the subject of baking… for some folks it solely counts as a savoury type of dish comparable to chorizo and halloumi with veg roasted in an oven, however I take advantage of it to explain many many issues. 

Though I known as my brownies, cookie bars and blondies traybakes, this cake is the definition of a traybake. It’s baked right into a 9×13″ tin (a big traybake tin) and it’s essentially the most excellent measurement for a bake like this. 

My different traybake truffles comparable to my carrot cake traybake, chocolate orange traybake and even my gingerbread traybake are all related in design and look – and I simply adore them. A easy one layer cake, smothered in a scrumptious kind of frosting and easily adorned is one of the best of one of the best. 


If you find yourself baking with bananas, over ripe and barely disgusting bananas are literally finest. You recognize the type which can be left within the fruit bowl for a lot too lengthy and simply appear to be they need to be thrown away?! By no means ever throw them away. 

Though I don’t personally eat something with bananas in as I can’t, I do know this kinda bake is supposed to be deliciously stodgy and heavenly – and I all the time get my trusty style testers to check it out for me. 

A high tip for in case your bananas aren’t fairly ripe sufficient is definitely to place them within the oven – it doesn’t take too lengthy, and also you don’t need too excessive a warmth – however they are going to soften, flip tremendous black on the skin, however be excellent for this cake – About 5-10 minutes at 160ºfan. 


  • Bananas – As mentioned above – squishy overripe bananas solely please! 
  • Butter – I take advantage of room temperature unsalted butter in my baking, however you need to use a ramification or a baking margarine for this bake should you choose!
  • Sugar – I like the style of this sugar however you need to use golden caster sugar, common caster sugar and even darkish brown delicate sugar should you choose. 
  • Flour & elevating brokers – you need the elevating agent that’s naturally on this flour, in addition to the baking powder 
  • Eggs – As all the time, I take advantage of medium eggs – however you need to use 4 giant should you solely have giant eggs round!
  • Soured cream – I used soured cream because it’s what I had, however you’ll be able to 100% use pure yoghurt, or buttermilk.
  • Vanilla – An optionally available further, however one thing I all the time add to my bakes as a result of yummy. 


So as a result of this cake felt extra dense and banana bread like, I felt like a cream cheese frosting would work finest. That is optionally available although – you’ll be able to 100% use one thing else comparable to a buttercream, or simply go away it as it’s with a drizzle of caramel maybe. 

For the cream cheese frosting although there are a couple of guidelines that it is advisable to stick by. Cream cheese frosting within the UK isn’t the best, so observe my weblog publish about it if you’re frightened, however take note of the substances:

  • Butter – For this frosting you MUST use block butter. Margarine/spreads don’t work with cream cheese frosting as they’re too delicate. 
  • Sugar – as all the time, icing sugar guys. 
  • Cream Cheese – I typically use Philadelphia to make my cream cheese frosting, you simply want to ensure no matter delicate cheese you employ is full-fat. 
  • Vanilla – I like so as to add for flavour as per standard, however that is optionally available. 


Ornament on a cake like that is so easy – and you may principally make it no matter you need it to be. I believed as a result of at any time when I see banana truffles they typically have a nutty addition, I’d use some chopped walnuts to brighten the cake as a result of yum. 

You should use banana chips, a swirl of caramel, something you fancy – or you’ll be able to go away it as it’s after all! There are not any guidelines on one thing like the extra substances – so that you do you! 

Ideas & Tips 

I all the time discover that with a cake like this you simply want to understand that some ovens can take a bit longer than others. It’s true of all baking and truffles annoyingly, however don’t be frightened if yours takes a bit longer or much less time! The fortunate factor with a cake like that is that they’re meant to be barely dense anyway! 

I all the time use an oven thermometer when I’ve a brand new oven or if bakes aren’t taking the time they need to and I actually would suggest it you probably have the identical drawback. 

The dimensions of the tin is necessary as effectively – I take advantage of a 9×13″ traybake tin. Some traybake tins come as this as normal, whereas others come as 9×12″. These tins may even work. Nevertheless if you wish to make a 9×9″ cake, it would be best to half the recipe!
