Sicilian sesame-coated cookies are crunchy, buttery, and nutty. These beloved mediterranean biscuits are a family cookie jar essential across the island.
Preheat oven to 350°F (175°C) and line a baking sheet with parchment.
In a large bowl, cream the butter and sugar together until pale and fluffy, about 3 minutes on medium speed.
Add eggs one at a time, mixing well after each; stir in vanilla extract.
In a separate bowl, whisk flour, baking powder, and salt; gradually add dry ingredients to the wet mixture, alternating with milk. Mix until dough comes together and is smooth but not sticky.
Pinch small portions (about 1.5 tablespoons each) and roll into short logs. Dip each log lightly in milk, then roll generously in sesame seeds to coat.
Arrange cookies on prepared baking sheet, spacing about 2 inches apart, and bake for 22–25 minutes, turning the tray halfway through, until golden brown and crisp.
Cool completely on a wire rack to achieve maximum crunch before storing in an airtight container.
