Banana Tray Bake with Cream Cheese Icing

black plate wth a small stgack of banana tray bake

This Banana Tray Bake recipe is sooooo delicious and easy to make. Come on, you must try this one. I know I only post recipes that I really like, but really, go for it.  Moist, light and super easy, that’s what you love, right?

There’s always a time when you have bananas that need to be used up, because they are over-ripe, and nobody really wants to eat them.  This is the perfect time to pull out this recipe.

Classes if you are local (Melbourne) or Zooms from anywhere 🙂

Cream cheese icing tip

When making cream cheese icing, it’s essential to have the butter and cream cheese at the same temperature (room temperature) before whipping.  If you take both butter and cream cheese straight from the fridge and beat, you’ll find the butter takes way longer to soften.

Is my butter too cold?

First, you’ll have bits of un-softened lumps of butter in your cream cheese. This makes it not so nice to eat, and if you’re going to pipe your icing, you’ll have bits of butter clogging up your piping bag.  If you’ve ever had this happen, you’ll know it’s a pain in the butt.

The solution to cold butter

Don’t microwave till it melts, you’ll change its chemical structure, and it won’t be light and fluffy when you whip it.  I advise grating it or chop it into small cubes, then beat it till it’s soft before adding the cream cheese.

Method Thermomix

Equipment

  • Thermomix

Ingredients
  

For the Cake

  • 115 g butter small cold cubes for Thermomix method
  • 280 g sugar
  • 2 eggs
  • 120 g sour cream
  • 1 tsp vanilla extract
  • 250 g wholemeal flour
  • 1 tsp baking soda
  • 1/4 tsp salt
  • 280- 360 g super ripe bananas mashed (about 2 really large)
  • 1 cup walnut pieces toasted

For the topping

  • 115 g butter
  • 225 g cream cheese
  • 400 gm icing sugar
  • 2 tsp vanilla

Instructions
 

  • Preheat the oven to 180°c

For the Cake

  • Toast the walnut pieces for ten minutes or until they become fragrant or crunch when you break them with your hands. Watch out they’re hot when they come out of the oven.
  • Weigh the flour, baking soda and salt into the TM bowl and sift with the MC in place on speed 3/5 seconds then remove and set aside
  • Weigh the banana into the TM bowl and chop on speed 3/6 sec and remove
  • Without washing the TM bowl weigh in the butter and sugar and beat on speed 5/10 seconds.
  • Add the butterfly into the TM bowl. Add the eggs, sour cream, vanilla and mix on speed 2/10 seconds
  • Return the flour mix, banana and walnuts and mix again on speed 3/10 seconds
  • Pour and spread into a greased 12×5-inch baking pan. Bake until a toothpick comes out clean Remove from the oven and allow to cool completely in the pan. The surface will become quite golden brown but don’t worry; it’s all about the sugars caramelising.

For the Topping

  • While the traybake is cooling, you can begin to make the frosting.
  • Weigh the butter into the TM bowl, if it’s really cold beat on speed 3/10 second then weigh in the cream cheese and vanilla. Beat on speed 3 until light and creamy. This will depend on how cold your ingredients are but check around 10 seconds then scrape the base and sides of your bowl and go again if it’s still not soft and fluffy. Weigh about 3/4 of the icing and beat on speed 3 with the MC in place. You’ll need to keep an eye on it it should take around 15 seconds with a scrape down in between. Add more icing sugar beating as you go until you reach the desired texture.

    Made this so many times and always successful and delicious. Love it with or without frosting. Freezes brilliantly too.

  2. My first truly successful Thermomix cake!! Thanks Bec. This is a delicious, light, evenly baked cake. Will make this again and again! Only made half the frosting (didn’t have anymore cream cheese) and actually found it a perfect amount for the whole 13×9” cake.
