Thermomix Banana Cake

Thermomix Banana Cake with Cream Cheese Frosting

One of my very favourite cakes in the world is a banana cake with cream cheese frosting. It probably helps that we always have heaps of ripe bananas in the fruit bowl (we’re a bit obsessed with bananas at our house)! Anyway, this banana cake is so simple. It takes no time at all to whip up and because it’s made from fruit it’s totally healthy (right!?). Just joking! But it is delicious, so it’s ok.

Oh and talking about delicious… that cream cheese frosting!!! I must say that by the time the frosting gets put on top of the cake, it’s seriously missing a few spoonfuls (ok a few may be an understatement). If you can restrain yourself from eating the cream cheese frosting straight from the TM bowl, then you deserve a medal. Clearly I’m not ever going to get that medal.

Luckily, you’ll end up with enough frosting to cover the entire top of the cake generously, or alternatively enough for a light covering of the top and sides. Sometimes I like to cut my banana cake in half and use half of the frosting as a middle layer – delicious!!

  4. Very simple cake and will definitely make it again – thank you.
    Mine turned out a lite dry. I cooked it for about 50 minutes so it is not that but I wondered if next time I should add a little more butter or try slowing the speed down on thermomix. That said, it went quickly!

  5. Thankyou! The cake was easy to prepare and tasted delicious. The icing was incredibly sweet. Could probably have had half or less of the icing sugar and butter.

  7. Is it 160°C fan forced? Or conventional? I had it in for the whole hour on conventional and it wasn’t cooked all the way through. Unfortunately I didn’t find this out until too late as my fork still came out clean.

  8. I have to make this cake on a regular basis (almost weekly), it is so simple to make and never lets me down. I usually add chocolate chips, fresh blueberries or raspberries to mine which everyone loves.
