    Add the sugar, egg, flour baking powder, salt and vanilla and stir through until the mixture is smooth.

  4. Step 4

    Spread the batter into the prepared tin and bake for 20-25 minutes. Remove from tin to cool completely before icing.

Method - Icing

    To make the icing, beat all the ingredients together in the bowl of an electric mixer until light and fluffy. Spread on top of the cooled slice.
