Vanilla cake

Heat the oven to 180°C . Lightly grease round cake tin with a little extra butter or margarine and cut a piece of greaseproof paper or non-stick baking parchment to fit the base of the tin.

Put all the ingredients into a large mixing bowl and beat with a wooden spoon or a hand-held mixer for 1 minute, or until just combined. It's important not to beat the batter too much - just long enough to make it smooth.

Pour or spoon the mixture into the tin, smooth the top and bake on the middle shelf of the oven for about 45-50 minutes. The cake is cooked when it looks well risen and golden; the top should spring back when lightly touched with a fingertip. Another test is to insert a skewer into the centre of the cake - it should come out clean.

Let the cake sit in the tin for 5 minutes, then gently run a knife around the edge and turn the cake out onto a wire rack to cool. Serve dusted with icing sugar.
