Follow these simple steps to create delicious Barazek right at home:

1. Preheat Oven: Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
2. Mix Dry Ingredients: In a bowl, combine the flour, baking powder, and salt. Set aside.
3. Cream Butter and Sugar: In another large bowl, cream together the softened butter and powdered sugar until light and fluffy.
4. Add Vanilla: Mix in the vanilla extract until evenly incorporated.
5. Combine Mixtures: Gradually add the dry ingredients to the creamed mixture, mixing well to form a soft dough.
6. Chill the Dough: Wrap the dough in plastic wrap and refrigerate for 30 minutes.
7. Prepare the Sesame Mixture: While the dough chills, place the toasted sesame seeds and chopped nuts on a shallow plate.
8. Shape Cookies: After chilling, scoop a tablespoon of dough and roll it into a ball. Flatten it slightly, then dip one side in the sesame-nut mixture.
9. Place on Baking Sheet: Arrange the cookies, sesame-side up, on the prepared baking sheet, leaving some space between them.
10. Egg Wash: Beat the egg and brush a thin layer over the top of each cookie for a nice glaze.
11. Bake: Place the baking sheet in the oven and bake for 15-20 minutes, or until the cookies are golden-brown.
12. Cool: Remove from the oven and allow to cool on the baking sheet for 10 minutes before transferring to a wire rack to cool completely.
