01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper.
02 - In a large mixing bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly distributed.
03 - Add the cold, cubed butter to the dry mixture. Using your fingertips or a pastry cutter, rub the butter into the flour until the mixture resembles coarse crumbs with pea-sized pieces remaining.
04 - In a separate bowl, whisk together the hummus, milk, and egg until smooth and well blended.
05 - Pour the wet mixture into the dry ingredients. Stir gently with a fork or spatula until just combined. Avoid overworking the dough to keep the scones tender.
06 - Gently fold in the chopped herbs, crumbled feta, and toasted sesame seeds if using, 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 baking sheet. Gather and re-roll scraps to cut additional scones.
08 - Optional: brush the tops of the scones 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 golden brown and well risen. Rotate the tray halfway through for even browning.
10 - Allow the scones to cool slightly on the baking sheet before transferring to a wire rack. Serve warm with extra hummus or a tangy yogurt dip.
