Ingredients
  

  • 45g cornflour
  • 155g gluten-free plain flour, plus extra for dusting
  • 1/4 tsp xanthan gum
  • 75g golden caster sugar
  • 125g cold unsalted butter, cut into cubes

Instructions
 

  • Line a 20cm x 20cm baking tin with baking parchment and set it aside.
  • In a food processor, combine the cornflour, gluten-free plain flour, xanthan gum, and golden caster sugar. Pulse a few times to blend.
  • Add the cold, cubed butter to the food processor and pulse until the mixture resembles breadcrumbs.
  • Transfer the mixture to a clean work surface. Use your hands to gently bring the dough together into a cohesive ball. Avoid overworking it.
  • Press the dough evenly into the prepared tin, creating a smooth surface. Chill it in the refrigerator for at least 20 minutes to firm up.
  • Preheat your oven to 180C (160C fan/gas 4).
  • Bake the shortbread for 18-22 minutes, or until lightly golden on the edges but still pale on top.
  • Remove the pan from the oven and score the cookies into 12 rectangles using a knife while they’re still warm.
  • Let the shortbread cool for 10 minutes in the tin before cutting through the scored lines completely.
  • Cool completely before serving or storing in an airtight tin.
