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

So we will 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 individuals relating to baking… for some individuals it solely counts as a savoury type of dish akin to chorizo and halloumi with veg roasted in an oven, however I take advantage of it to explain many many issues. 

Though I referred to 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 good dimension for a bake like this. 

My different traybake truffles akin 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 embellished is the perfect of the perfect. 


When you’re baking with bananas, over ripe and barely disgusting bananas are literally finest. You already know the sort which can be left within the fruit bowl for much too lengthy and simply seem like 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 surface, however be good 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 diffusion or a baking margarine for this bake in the event you desire!
  • Sugar – I like the style of this sugar however you need to use golden caster sugar, common caster sugar and even darkish brown gentle sugar in the event you desire. 
  • 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 massive in the event you solely have massive eggs round!
  • Soured cream – I used soured cream because it’s what I had, however you possibly can 100% use pure yoghurt, or buttermilk.
  • Vanilla – An non-obligatory 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 non-obligatory although – you possibly can 100% use one thing else akin to a buttercream, or simply depart it as it’s with a drizzle of caramel maybe. 

For the cream cheese frosting although there are a number of guidelines that you must stick by. Cream cheese frosting within the UK shouldn’t be the simplest, so observe my weblog submit about it in case you are apprehensive, however take note of the components:

  • Butter – For this frosting you MUST use block butter. Margarine/spreads don’t work with cream cheese frosting as they’re too gentle. 
  • 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 gentle cheese you utilize is full-fat. 
  • Vanilla – I like so as to add for flavour as per common, however that is non-obligatory. 


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 embellish the cake as a result of yum. 

You should use banana chips, a swirl of caramel, something you fancy – or you possibly can depart it as it’s in fact! There are not any guidelines on one thing like the extra components – so that you do you! 

Suggestions & Methods 

I all the time discover that with a cake like this you simply want to grasp that some ovens can take a bit longer than others. It’s true of all baking and truffles annoyingly, however don’t be apprehensive 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 advocate it if in case you have the identical drawback. 

The dimensions of the tin is necessary as nicely – 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 can even work. Nevertheless if you wish to make a 9×9″ cake, it would be best to half the recipe!
