Preheat oven to 375F and line a baking sheet with parchment paper.
Whisk flour, salt and baking powder in a bowl. Drain any excess liquid from the yogurt and add to flour mixture. Mix until a dough forms.
Transfer to a floured surface and roll out to form your dough. Divide into 8 equal balls. Flatten each one into circles, fill with ½ tablespoon cream cheese and any additional filling.
Cover the dough well and roll into a ball. Place on a baking sheet, top with egg wash and sprinkle seasoning. Bake at 375 F for 20 minutes.
