Line two 20 x 30cm slice trays with baking paper. Or for a thicker shortbread, you can line on larger tray with baking paper.
Preheat the oven to 150˚C (300˚F).
In a stand mixer, beat the butter and the icing sugar and beat light and fluffy. This step can also be done with a hand mixer in a bowl.
Add the cornflour and the plain flour and mix until a soft dough forms.
Press into the prepared slice trays.
Lightly score out squares with a butter knife or a bench scraper and then prick each slice with a fork a couple of times.
Bake in the oven for around 15 to 20 minutes in the small trays or 25 to 30 minutes in a larger tray. The shortbread should be lightly golden in colour, and crisp.
Remove the shortbread from the oven and cut into slices.
Allow to cool for at least one hour in the oven before removing and completely cooling on the bench.
Shortbread Cookies
Line a baking tray with baking paper.
Preheat the oven to 150˚C (300˚F).
In a stand mixer with the paddle attachment, beat the butter and the icing sugar and beat light and fluffy. This step can also be done with a hand mixer in a bowl.
Scrape the bottom and sides of the bowl and then add the cornflour and the plain flour and mix until a soft dough forms.
Use a 1 Tablespoon scoop to measure out balls of dough. Roll these balls between your hands to create a smooth, round ball.
Place the balls on the prepared baking tray, leaving at least 5 cm in between each one.
Lightly flatten each cookie with your palm and then gently press down with a fork.
Bake for 15 to 20 minutes or until the edges are just barely starting to brown.
Allow to cool for at least one hour in the oven before removing and completely cooling on the bench.
