Pour the flour into a bowl, creating a small well in the center. Add the yogurt to the well, followed by the sugar, salt, and baking powder.
Mix the ingredients together using your hands, working from the center outwards until you achieve a smooth, sticky dough.
Place the dough out onto a lightly floured surface and cut it into 8 equal-sized pieces using a knife.
Roll each piece into a ball and rest them for about 5 minutes.
Using a rolling pin, shape each dough ball into a round flatbread.
Dust each Parlenka generously with flour to prevent sticking, or place a piece of floured baking paper between them.
Heat a pan to a moderately high temperature and begin cooking the Parlenki. Cook for 2-3 minutes until the underside is browned. Flip and cook for an additional 2-3 minutes. Repeat with the remaining Parlenki.
While the Parlenka is still warm, brush it with melted butter and crushed garlic for extra flavor. If desired, sprinkle chili or sweet red pepper on top for added taste.
Enjoy your Parlenka warm.
