Melt the butter gently in a small saucepan, then cool a little. Add the sugar, eggs, milk and vanilla essence. Sift the dry ingredients into a wide bowl and pour in the butter mixture. Stir everything together adding the mashed bananas; do not overmix or beat the batter.
Turn the mixture into a lightly buttered 6-cup ring tin and bake for 30 minutes. The cake should be browned, slightly shrinking from the sides of the tin and a skewer inserted in the middle should come out clean.
Lemon Icing: Put the icing sugar in a bowl and add enough lemon juice to make it a barely pourable consistency. Spread over the cooled cake and leave to set.
Altered ingredient amounts.
I doubled the butter, eggs and bananas and it made a larger batch, and the cake was extra moist. Also i used 1 lemon and added an extra cup of icing sugar to the icing mix and a little yellow food dye to give it colour. - 21 Jan 2011
I have also made this into muffins but altered the recipe slightly: brown sugar instead of white, wholemeal flour instead of normal, added cinnamon and sprinkled on top with a mix of walnut, brown sugar, and cinnamon. Beautiful. - 11 Aug 2012
