Prepare the Dough

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat.
2. Mix the Butter and Sugar: In a large mixing bowl, cream together the softened butter and powdered sugar until light and fluffy. This step is important as it creates the soft texture of the cookies.
3. Add the Dry Ingredients: Gradually add the flour and salt, mixing until a soft dough forms. You may need to use your hands towards the end to bring the dough together.
4. Add Vanilla: Stir in the vanilla extract for a hint of warmth and depth of flavor.

Shape the Cookies

1. Roll the Dough: Take small amounts of dough (about 1 tablespoon per cookie) and roll them into balls. Place them on the prepared baking sheet, spacing them about 2 inches apart.
2. Flatten the Balls: Gently press each dough ball with the back of a fork to flatten them slightly. This will give them that classic shortbread look.
3. Place the Cherries: Gently press one glace cherry into the center of each cookie. You want to make sure the cherry stays in place while baking.

Bake the Cookies

1. Bake: Bake the cookies in the preheated oven for 25-30 minutes, or until they are golden around the edges.
2. Cool: Allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
