Preheat your oven to 350 Degrees Farenheit. Grease a baking tray or line with parchment paper and set aside.
Put room temperature butter and sugar in a bowl. Use a fork or wooden spoon to mix together until well combined.
Add in half of your flour and the salt. Mix together. The mixture will be very crumbly at this stage.
Add in the remaining flour and mix well. Use your hand to combine everything to form a ball of dough

Wrap dough in a plastic wrap and try to form it into a rectangle as much as you can with your hand. It should be about half an inch thick.
Now place the dough in a fridge and let it cool for about 30 minutes. You need to do this so you can shape your cookies properly.  While the dough is in the fridge, preheat oven to 350 degrees F (180 degrees C).Take out dough and roll with a rolling pin to about ¼ inch thick. Leave the plastic wrap on while doing this.

Now open the wrap then you cut the dough into rectangles. If you have a cookie cutter, you could just use it to cut to desired shapes.
Place your cuts on trays lined with parchment paper.
Use a fork to poke each piece a couple of times.
Now bake in the oven for about 10 minutes until light golden in color.
