I make a lot of Thermomix banana bread for my kids - they love it in their lunch boxes or for an after school snack.

But sometimes I like to mix it up a bit and make a banana cake instead. It's similar but is made even better by the addition of irresistible cream cheese frosting.

If you like banana bread then give this a go - it's next level delicious!

It's smothered in delicious cream cheese frosting, making it next-level delicious.

It's a great way to use up overripe bananas.

Ingredients

Banana cake is a great way of using up any overripe bananas sitting in your fruit bowl.

Here's what else you'll need (exact quantities can be found in the recipe card at the bottom of this post).

Bananas - Make sure you choose nice ripe bananas for this Thermomix banana bread recipe. You want them to be nice and ripe to get the natural sweetness out of the fruit. They are best when they are starting to go brown on the outside, but not so ripe that they are mushy on the inside.
Vanilla extract
Butter
Brown sugar - If you don't have brown sugar, you could just use caster sugar or granulated sugar. However, the brown sugar gives it an incredible richness.
Eggs
Plain flour - aka all-purpose flour. You could substitute for self-raising flour and skip the baking powder, but I think you always get better results using plain flour and baking powder.
Baking powder
Bicarbonate of soda - aka baking soda.

For the Cream Cheese Frosting

Ingredients for cream cheese frosting laid out on a table and labelled.

Icing sugar - if you don't have icing sugar, you can use any white sugar and mill it first: do this for around 30 seconds at speed 10. However, I don't think the results are ever as good as shop-bought icing sugar.
Cream cheese - I use Philadelphia.
Butter
Vanilla extract

How to make Banana Cake

Making banana cake in the Thermomix is quick and easy. Exact step-by-step instructions can be found in the recipe card at the bottom of the post.

Start by mashing up the bananas with the vanilla extract in the Thermomix. Then set this mixture aside.

Next cream the butter and sugar together, before mixing in the eggs and banana mixture.

Then you just need to add the flour dry ingredients and mix for 20 seconds. And it's done!

Transfer the cake batter to a lined cake tin and bake it in the oven for around 45 minutes, or until a knife comes away clean when inserted into the middle of the cake.

I use an 8-inch cake tin for this. You could also use a round cake tin.

Now remove the cake from the tin and transfer it to a wire rack to cool completely before adding the frosting.
