Ingredients

Cake

  • 125 grams unsalted butter 1/2 cup + 1 tablespoon
  • 250 grams sugar 1 and 1/4 cups
  • 2 large eggs
  • 2 teaspoons vanilla extract
  • 250 grams plain / all purpose flour 2 cups
  • 2 teaspoons baking powder
  • 1/2 teaspoon salt
  • 4 ripe medium sized bananas - mashed

Frosting

  • 100 grams unsalted butter 1/2 cup
  • 250 grams icing sugar 2 cups
  • Zest 1 lemon
  • Juice 1 lemon

Instructions

Cake

  • Preheat your oven to 180C/350F/Gas mark 4 and lightly grease & line a 9x9 inch square tin and place to one side.
  • Beat the butter till it is light and fluffy then add in the sugar and beat for a few more minutes until it is well incorporated.
  • Add in the eggs and vanilla and again mix until well incorporated.
  • Pour in half of the flour, the baking powder and salt and mix.
  • Add in the mashed banana and mix until just combined.
  • Pour in the remaining flour and beat until everything is mixed together.
  • Scoop the batter into your prepared tin and place in your hot oven for 40-45 minutes.
  • Test the cake for doneness by inserting a pick into the centre of the cake, if it comes out clean then the cake is baked. If not then bake for a few minutes longer and test again.
  • If you feel your cake is browning too much then cover with a bit of tin foil and continue to bake until the cake is fully baked.
  • Take it out of the oven and allow it to cool for 15 minutes in its tin before transferring it to a wire rack to fully cool down.

Frosting

  • Once the cake is fully cooled down its time to make the frosting.
  • Beat the butter until it is very pale. Add in the icing sugar and beat until everything is soft, pale and fluffy.
  • Zest your lemon into the frosting and then juice it. Mix this into the frosting and spread it evenly over your cake.
  • Kept in an airtight container at room temperature this cake will last 5 days.
  • Unfrosted this cake freezes well for 3 months.

Notes

Like most banana cakes this cake actually tastes better on day 2, once the flavours have matured.
