Ingredients

Shortbread Layer

  • 110 g butter (salted or unsalted) softened
  • 60 g icing sugar sifted
  • 115 g plain flour
  • 30 g cornflour

Lemon Curd Layer

  • 3 eggs at room temperature
  • 200 g caster or granulated sugar
  • 20 g plain flour
  • 1 tablespoon lemon zest remember to do this before juicing the lemons
  • 125 ml lemon juice

Instructions

  • Preheat oven to 180°C / 160°C Fan / 350°F / Gas Mark 4. Line a 20cm / 8-inch square cake tin with oil and line with parchment paper with overhang (so it can be lifted out once cooked).
  • Make the shortbread base by combining the softened butter and sugar until light and fluffy. Now add the flour and cornflour, just mix until a crumbly dough forms. Tip the shortbread dough in the tin and evenly press out until lightly compact.
  • Bake the base for 20 minutes or until lightly golden. While the shortbread is baking, prepare the lemon curd topping.
  • In a large mixing bowl, combine all the ingredients listed for the lemon curd filling. Whisk together until fully incorporated.
  • Once the shortbread layer is baked, pour the lemon curd filling directly on top and bake for 20 minutes.
  • Remove the lemon bars from the oven, allow to cool at room temperature for around a hour. Chill in the fridge for at least 3 hours or up to overnight until set.
  • When ready to serve, slice up into 16 equally sized bars, dust lightly with icing sugar right before serving - this will sweat and melt away so dust right before eating.
    The lemon bars will keep for up to a week stored in the fridge.
