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 and rub it into the dry ingredients with your fingertips until the mixture resembles coarse crumbs.
04 - In a separate bowl, whisk together the hummus, milk, and egg until smooth.
05 - Pour the wet mixture into the dry ingredients and fold gently until just combined. Do not overwork the dough.
06 - Gently fold in any optional add-ins such as fresh herbs, crumbled feta, or toasted sesame seeds.
07 - Turn the dough out onto a lightly floured surface and pat into a 1-inch thick round. Cut out scones using a 2.5-inch round cutter and place on the prepared tray. Re-roll scraps as needed.
08 - Optionally brush the tops with a little milk and sprinkle with extra sesame seeds or herbs.
09 - Bake for 18 to 20 minutes until the scones are golden brown and well risen.
10 - Allow scones to cool slightly on the tray before serving warm.
