Preheat your oven to 350°F (175°C).

In a large mixing bowl, combine the softened butter and salt, mixing until creamy. If using, add the vanilla extract now.

Gradually add the flour, mixing until a dough-like consistency is achieved.

On a lightly floured surface, roll out the dough to about 1/4 inch thick. Use cookie cutters or cut into rectangles.

Place the cut cookies on a baking sheet lined with parchment paper.

Bake in the preheated oven for 15-18 minutes until the edges are lightly golden.

Let the cookies cool on a wire rack before enjoying.
