Chocolate Banana Cake

A loaf cake made with the winning combination of chocolate and banana!


Cream together using mixer:

  • 113 g unsalted butter At room temperature
  • 180 g sugar Original recipes calls for 200g I have lessened it.

Mix in a bowl (dry ingredients):

  • 150 g plain flour
  • 20 g cocoa powder Use good quality cocoa powder.
  • 1 tsp baking soda
  • 1 tsp salt


  • 3 mashed very ripe bananas If using frozen ones, don't let them thaw too much they will become watery.
  • 2 eggs
  • 1 tsp vanilla essence
  • 110 g sour cream I have substituted with greek yoghurt. Same amount.
  • 80 g chocolate chips


  • Preheat oven to 175C. Grease and line a loaf pan.
  • Cream the butter and sugar until well combined for 2-3 minutes. Add eggs in one at a time with vanilla essence.
  • Add the dry ingredients and beat well. Add in bananans, sour cream and chocolate chips and beat till well combined. Don't overmix.
  • Pour batter out into loaf pan (you may add more chocolate chips on top) and bake for 1 hour - 1 hour 10 mins. Leave to cool in pan for some time before turning out and slicing.


Here are my top tips:
  • Be sure the bananas are overripe.
  • Don't skip the sour cream/greek yoghurt - it gives the cake the moistness it deserves.
  • Add more chocolate chips!
  • The cake freezes very well. Wrap in cling flim or foil and store. Thaw overnight in fridge before serving.
