Preheat oven to 400F. Line a large baking sheet with parchment paper. Set aside.
In a large bowl, combine flour, cocoa powder, sugar, baking powder, and salt. Work in frozen butter with fingers or a pastry cutter until crumbly.
In a separate medium bowl, whisk egg, milk, yogurt, and vanilla until smooth. Add liquid mixture, chocolate chips, and cherries to flour mixture and very gently fold until a dough forms.
Turn dough onto a floured surface and very gently knead several times until dough comes together. Pat dough into a 1-in thick round.** Cut round into 8 wedges and place wedges 2-in apart on prepared baking sheet. Chill scones in freezer 15 minutes.
Bake scones at 400F 18-22 minutes until centers are set. Cool scones on baking sheet 10 minutes, then transfer to a wire cooling rack. Serve scones warm and enjoy!
