01 - Preheat oven to 400°F. Line a baking tray with parchment paper.
02 - In a large bowl, whisk together the flour, baking powder, baking soda, and salt until evenly distributed.
03 - Add the cold cubed butter to the dry mixture. Using your fingertips, rub the butter into the flour until the texture resembles coarse crumbs with some pea-sized pieces remaining.
04 - In a separate bowl, whisk together the hummus, milk, and egg until smooth and well combined.
05 - Pour the wet mixture into the dry ingredients and fold gently with a spatula until just combined. Avoid overworking the dough to keep the scones tender.
06 - Gently fold in chopped herbs, crumbled feta, and toasted sesame seeds if desired, distributing them evenly throughout the dough.
07 - Turn the dough out onto a lightly floured surface. Pat it into a 1-inch thick round. Using a 2.5-inch round cutter, cut out scones and place them on the prepared tray. Gather and re-roll scraps to cut additional scones.
08 - Optionally brush the tops with a little milk and sprinkle with extra sesame seeds or herbs for a golden finish.
09 - Bake for 18 to 20 minutes until the scones are risen and golden brown on top.
10 - Allow the scones to cool slightly on the tray before serving warm with extra hummus or a tangy yogurt dip.
