Preheat your oven to 350°F (175°C) and line two baking sheets with parchment paper.

In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.

Stir in the vanilla extract until fully combined.

Gradually add the flour and salt, mixing until just combined to avoid tough cookies.

Roll out the dough on a lightly floured surface to about 1/4 inch thick and cut into heart shapes.

Place on prepared baking sheets and bake for 12-15 minutes or until lightly golden around the edges. Cool on wire racks before serving.
