Preheat oven to 350F. Line a large baking sheet with parchment paper.
Wash and chop apple into small pieces. There is no need to peel the apple and as a bonus the skin adds extra nutrients. Set aside.
Add flour, baking powder and cinnamon to a large bowl. Mix well.
Add sourdough discard, Greek yogurt, maple syrup, milk and vanilla to the dry ingredients. Mix with a large spoon until the flour starts to incorporate into the mixture.
Add the chopped apples. Use your hands to continue mixing the dough until a ball of dough forms and the flour is completely mixed in.
Place a piece of parchment paper onto a large cutting surface. Gently shape the ball of dough into a flat round disc around ½ inch thickness and place onto parchment paper.
Use a pizza cutter or sharp knife to cut dough into eight slices just like slicing a pizza.
Place dough triangles onto prepared baking pan.
Bake for 16-18 minutes or until the tops of the scones turn golden brown. Remove pan from oven and let the scones cool for 5 minutes before transferring to a wire rack to cool completely. Makes 8 scones.
