Preparation Steps

• Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.
• In a medium bowl, cream together the softened butter and sugar until light and fluffy.
• Beat in the egg yolk and vanilla extract until well combined.
• Gradually mix in the flour and salt until a soft dough forms.
• Roll the dough into small balls (about 1 tablespoon each) and place them on the prepared baking sheet, spacing them about 2 inches apart.
• Gently flatten each ball with the bottom of a fork or your thumb to form a cookie.
• Bake for 10–12 minutes, or until the edges are lightly golden. Allow to cool on the baking sheet for 5 minutes before transferring to a wire rack.
