Wholesome Ingredients for These Gluten-Free Shortbread Cookies

Every ingredient in these cookies has been chosen to deliver both flavor and nutritional benefits. Here’s a closer look:

• Gluten-free plain flour: We use a blend of gluten-free plain flour to replicate the structure of traditional shortbread. Be sure to use a high-quality mix that contains xanthan gum or other binders for the best results.
• Cornflour: Cornflour keeps the texture light and ensures that signature crumbliness. This ingredient is essential for achieving the perfect shortbread texture.
• Unsalted butter: Butter brings a rich, indulgent flavor and creates that sought-after melt-in-your-mouth feel. Use cold butter for a proper crumbly texture.
• Golden caster sugar: This sugar variety offers a subtle caramel-like sweetness without overpowering the buttery base of the cookies.

Swap suggestion: For a dairy-free alternative, replace butter with a plant-based butter substitute. And for a lower sugar option, consider using a monk fruit sweetener blend that’s designed for baking.

How to Make Gluten-Free Shortbread Cookies

1. Line a 20cm x 20cm baking tin with baking parchment and set it aside.
2. In a food processor, combine the cornflour, gluten-free plain flour, xanthan gum, and golden caster sugar. Pulse a few times to blend.

6. Preheat your oven to 180C (160C fan/gas 4).

8. Remove the pan from the oven and score the cookies into 12 rectangles using a knife while they’re still warm.
9. Let the shortbread cool for 10 minutes in the tin before cutting through the scored lines completely.
10. Cool completely before serving or storing in an airtight tin.
