Get a bowl, put in your butter and sugar, whisk till smooth and fluffy.
You put your corn flour, cake flour and salt in the same bowl where you have your butter and sugar, mix everything to combine, cover it with a foil wrap and refrigerate for about 30mins.
After 30mins you scoop and measure 20g with a scale for each cookie or even more depends on how big you want your cookies.
Roll with your hands to smoothen, you can drop it on a flat surface and then press down with a fork.
Bake for 40-45mins @170C (Don't forget to flip it over to the other side) and here you have your delicious “crunchy butter cookies”.
