Place butter in the freezer for 10-15 minutes if not already frozen. Preheat oven to 400F.
Dice apples and combine einkorn flour, sugar, baking powder, cinnamon, and salt in a large mixing bowl.
Cut in the cold butter using a pastry cutter or food processor, until the flour mixture resembles course crumbs.
Add sourdough starter, vanilla, cream, and apples and mix with a wooden spoon or your hands just until combined. Don't overhandle the dough, because you want to keep it as cold as possible.
Turn dough out on counter or directly onto a parchment lined baking sheet. Gently shape into a 3/4 inch thick circle using a rolling pin or your hands.
Cut the dough into 8 equal triangles and bake for 20-25 minutes until light golden brown. To discourage spreading, bake the scones in the circle without taking the triangles apart.
Let cool on a wire rack and enjoy!
