In a medium bowl, whisk together the flour, cocoa powder, baking powder, salt and baking soda; set aside.

In a separate bowl, cream together the butter, brown sugar, and granulated sugar. Add the eggs, and greek yogurt and mix well.

Add the melted chocolate, vanilla extract, apple cider vinegar, and red color and mix again. Pour the flour mixture into the butter mixture in 2-3 smaller additions, mixing well after each. Batter will be thick and sticky.

Cover the cookie dough with plastic wrap and refrigerate for at least 3 hours.

Preheat the oven to 350°F (180°C), or 160°C if using a fan oven. Line three baking sheets with parchment paper and set aside.

Roll heaping tablespoons of dough into balls, then place into the granulated sugar and roll to coat. Transfer to the powdered sugar and roll to coat completely.

Place sugar coated cookie dough balls on the prepared baking sheet 2 inches apart.

Bake in the preheated oven for 8-10 minutes, or until the cookies have puffed and crackled. Allow to cool 10 minutes before transferring to a wire cooling rack to cool completely.
