Chocolate Banana Cake…


Banana bread is a popular and easy bake to make. It’s one of the first things we learnt to bake in school and has always been a staple in our lives whilst growing up and it’s something we have baked quite a lot while being on Slimming World.

This recipe is more a cake than a bread and is super moist and fluffy, and it also includes chocolate, mmmmm.

One tip I will advise is to make sure your banana is as black as you can get, not mouldy, just black. Its sweeter and more ideal for baking with than an under ripe banana which will have no flavour once cooked.

As always we always include a syn value for cooked fruit as per the Slimming World guidelines and its up to the individual to syn it, some people do and some people don’t but we will always recommend people to do as the plan suggests to protect your weight loss.


Some recommended items from our kitchen to make this dish…

  • Silicone whisks in varying sizes, much prefer silicone to metal as it rusts or an electric whisk to save on arm ache.
  • Double sided dry and liquid measuring spoons for times when you need to measure both liquid and dry ingredients.
  • Mixing bowls are always wanted in this household and these stackable ones save so much space in our cupboards.
  • 7″ loose bottom spring form cake tin.
  • Cake cooling racks, so handy to have.
