  • Bar tin (Loaf tin) 24cm x 14cm x 7cm


Banana Cake

  • 2/3 cup caster sugar
  • 1/3 cup brown sugar
  • 60 grams butter
  • 1 egg
  • 3 medium bananas (ripe bananas work best - I freeze them when they've passed their best and thaw them before cooking)
  • 1 1/2 cups plain flour
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon bicarb soda
  • 1 tablespoon milk

Lemon Frosting

  • 250 grams cream cheese
  • 50 grams butter
  • 1 small lemon
  • 1/2 cup icing sugar


Banana Cake

  • Beat butter and sugar in a stand mixer on medium-high for 5 minutes.
  • Add whisked egg and beat again for a few minutes.
  • Add mashed bananas and beat again for one minute.
  • Add sifted flour and baking powder gradually. Mix well.
  • Dissolve bicarb soda in milk and add to mixture. Mix well.
  • Pour mixture into a large well-greased bar tin (approx 24cm x 14cm x 7cm). You may also wish to line the bottom of the pan with baking paper.
  • Bake at 170 degrees celsius (fan-forced) for 35-40 minutes.
  • Allow to cool in the pan for 5-10 minutes then turn out onto a wire rack to cool.

Lemon Frosting

  • Cut cream cheese and butter into small cubes and beat until soft.
  • Cut lemon in half and slice off 3 small rounds from the inside of the halves. Juice the remaining lemon and finely grate some zest from the sides of the lemon halves.
  • Add all of the lemon juice and zest to the mixture and beat well.
  • Add the icing sugar and continue to beat until soft and fluffy.


  • Slice top of cake to level if necessary.
  • Add frosting and smooth over top. Dab with spatula to create a textured look.
  • Slice lemon round almost in half. Twist and place along top of cake to create a swirl effect.
