Banana Chocolate Cake

This is a family favourite. With 3 boys to fill up (one loves chocolate cake, the others banana), it does the job in one easy mixture and they all love it. It can easily be doubled and has been used on numerous occasions for ‘birthday cakes’.

I ice it with a simple chocolate icing.

  • Prep time: 20 mins
  • Cook time: 40 mins
  • Finished in: 1 hour


  • 100g butter
  • 1 cup sugar
  • 1 egg
  • 1/2 cup plain yoghurt

  • 1 banana, mashed
  • 1 1/2 cups self raising flour
  • 1/4 cup cocoa
  • pinch salt
  • 1 teaspoon bakins soda
  • 1/2 cup boiling water


Preheat oven to 180 C.
Beat together butter and sugar, add egg and mix well. Mix in yoghurt and then banana and sifted dry ingredients. Sitr through baking soda dissolved in hot water. Pour mixture into a greased, lined cake pan (22 cm). (I use a ring pan)
Bake for 30-40 minutes until cake tests cooked.
