Prepare Buttermilk

Add vinegar and soy milk into a measuring cup.  Whisk the vinegar and milk, then set aside.

Whisk Dry Ingredients

Whisk flour, sugar, salt and baking soda together in a large mixing bowl.

Cut in Butter

Add cold vegan butter to your flour mixture in small pieces. Cut it throughout the flour (with a pastry cutter or fork).

Form Dough

Pour your buttermilk into the buttery flour and stir until dough forms. Gently knead the dough and transfer to a baking tray.

Bake in Oven

Shape the dough into a ball, keeping as much height in the loaf as possible. Score an X into the top of your dough with a knife, then bake for 45-50 minutes.
