Crunchy sesame cookies with fragrant, toasted sesame flavor are a traditional Chinese treat. A family recipe with fresh, nutty sweetness.
Preheat oven to 350°F (175°C) and line a baking sheet with parchment paper for even baking.
In a medium bowl, whisk together flour, salt, and baking powder for uniform drying and leavening.
In a large mixing bowl, cream softened butter and granulated sugar until pale and fluffy, about 2–3 minutes on medium speed; then beat in egg and vanilla extract until fully combined.
Gradually add dry ingredients to the butter mixture, mixing on low speed just until combined. Fold in toasted sesame seeds carefully for texture.
Scoop tablespoon-sized portions onto the prepared baking sheet and gently flatten each cookie. Bake on center rack for 14–16 minutes until golden around the edges. Let cool on sheet for 5 minutes to set before transferring to a wire rack.
