Preheat oven to 350F/177C. Coat a medium sized loaf pan or ceramic pan with a dab of olive oil cooking spray Add flour, dry yeast and sea salt to a medium bowl. Whisk dry ingredients until well-incorporated.
Add vegan buttermilk.
Add 1 tablespoon of vegan butter and mix everything with a fork or spatula until wet and dry ingredients are well-combined.
Place dough on a flat surface dusted with flour. Using the heel of your clean hands, knead your dough by pushing it down a few times. Turn 45 degrees, and knead again. Repeat this process until your dough is smooth and supple. If you're unsure about the dough's readiness, give it the windowpane test. Once ready, form dough into a round ball.
Place dough in a bowl, cover with a clean dish towel and set aside for an hour in a warm place for dough to rise.
In a separate bowl, add remaining butter, minced garlic and chopped fresh parsley.
Mix together with a fork until the butter mixture is well-blended.
When the dough has doubled in size, transfer it to a flat surface that's sprinkled with flour. Using a rolling pin, roll dough into a 16x10 inch (25x41cm) rectangle. Using a fork or spatula, top dough with butter mixture.
Slather mixture over the dough using the same fork or spatula.
Roll the dough into a log.
Slice the dough in half down the middle, length-wise.
Braid the dough as if your braiding two pieces of rope as seen in the picture below.
Coil the braided rope like a snake, then coil the other side in the opposite direction so it forms a sort-of S-shape. Transfer braided dough into your prepared loaf pan. Brush with melted vegan butter and bake for 35 minutes, ensuring the crust is golden brown. Slice and enjoy.
