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

In a mixing bowl, cream together the unsalted butter and granulated sugar until light and fluffy.

Mix in the vanilla extract and salt until well combined.

Gradually add the sifted flour while mixing at low speed until the dough forms.

Scoop tablespoon-sized portions of dough, roll into balls, and shape them into hearts on the baking sheet.

Bake for 12-15 minutes until lightly golden around the edges. Cool slightly before transferring to wire racks.
