Rich, crumbly shortbread cookies made with pure butter are a simple, elegant family treat. These classic, melt-in-your-mouth cookies are perfect for tea time and holiday gifting.
Preheat oven to 325°F (163°C) and line a baking sheet with parchment paper.
In a large mixing bowl, cream together the unsalted butter and powdered sugar until smooth and light, about 2–3 minutes on medium speed.
Stir in vanilla extract and salt, mixing until combined.
Gradually add all-purpose flour, mixing at low speed and scraping down bowl, until a soft, crumbly dough forms.
Shape dough into 1-inch balls or press into a slab and cut into desired shapes, then place on prepared baking sheet, leaving space between cookies.
Bake for 18–22 minutes, watching closely — cookies should remain pale but set, with barely golden edges.
Let cool on the pan for 5 minutes, then transfer carefully to a wire rack for full cooling. Store in an airtight container.
