Stephanie’s Zingy Lemon Slice

This well-known treat is an ideal recipe for a very young cook. The slice has three distinct layers: a biscuit base, a gooey, sharp lemon middle and a soft cake topping.

It must be quite cold before cutting or the gooey part won’t be set. Cut it with a very sharp knife dipped in very hot water, to avoid the slice sticking to the knife.

Makes: 15-18


  • butter, for greasing
  • 3 lemons
  • 4 large eggs
  • 11/2 cups castor sugar 1/4 cup plain flour
  • pure icing sugar, for dusting


  • 175g plain flour
  • 1/3 cup castor sugar 150g cold butter, roughly chopped


Preheat the oven to 180°C (160°C, if fan-forced). Butter a 18cm × 28cm slice tin and line it with baking paper long enough to have a little overlap at the sides to lift out the slice.

To make the base, whizz the flour and sugar in a food processor for a few seconds, then add the butter and process until the mixture starts to form a ball. Tip the dough into the prepared tin, and press over the base with your fingers. Bake for 20 minutes until golden. At this point, it might be a good idea to set a timer for 15 minutes, as you need to do a few things in the minutes before the base is cooked.

When the base is nearly cooked, zest and juice the lemons. Strain the juice to remove any seeds.

Whisk the eggs and sugar in a large bowl until well mixed but not thick. Stir in the lemon juice and zest, then sift in the flour and whisk gently to combine.

Remove the base from the oven and reset the oven temperature to 150°C (130°C, if fan-forced). Carefully and slowly pour the lemon mixture over the base – do this gently as you don’t want the base to lift. (A good way to do this is to pour the mixture over the back of a spoon to reduce the impact of the liquid – in this case, it might be a good idea to put the mixture into a jug.) Bake for about 35 minutes until the top is golden and feels a little springy. Stand the tin on a wire rack to cool.

When completely cold, lift the slice out of the tin and cut it into fingers. Serve dusted with icing sugar and with a dollop of the best cream.

A note on flour: I have chosen to measure flour by weight rather than cups, unless the result doesn’t depend on an exact amount. Precision is important when baking. Sometimes it is straightforward to convert a weight measurement to cups, but sometimes it is not and disappointment can follow. One cup of flour weighs 150g.
