In a medium-sized bowl, mix dry ingredients together: flour, yeast, and salt.
Add buttermilk and 1 tablespoon of butter. Mix everything using a spatula until you form a small ball of dough. Put it aside somewhere warm for about 1 hour.
When the dough doubled its size, transfer it to a flat surface, sprinkle it with flour, and using a rolling pin, roll dough into a 16-10-inch rectangle.
In a separate bowl, combine remaining butter, freshly chopped garlic, and parsley. Transfer mixture onto a dough, and using a fork or knife, spread it evenly. Roll the dough into a log.
Cut the log of dough in half and braid it like on picture. Coil the rope like a snake, then other side of rope in opposite direction. Transfer into a medium-sized loaf pan.
Bake for 35 minutes at 350F.
