Preheat oven to 400°F. Line a baking sheet with parchment paper.
To a medium-sized bowl or food processor, add flour, sugar, salt, and baking powder.
Cut in the butter until crumbly. If using a food processor, dump into a medium-sized bowl. Add chocolate chips and mix gently.
In a separate bowl, combine sourdough discard, egg, vanilla, and cream. Mix well.
Add the wet ingredients to the dry ingredients and gently mix with a fork. Fold over itself a few times to ensure it's mixed well enough without over mixing. You should be able to form a shaggy dough ball.
Place the scone dough on the parchment paper lined baking sheet and press out to form a circle. Cut into 8 triangles. Or you can press into a long rectangle, cut in half length-wise, and cut each half into 14 mini scones.
Separate the scones out evenly. Brush each scone with milk and sprinkle with sugar.
Bake for 18-22 minutes until lightly golden. Bake mini scones for 14-16 minutes.
Cool on a wire rack and store in an air-tight container. Or freeze.
Enjoy with a hot cup of coffee! Enjoy!
