Prepare the biscuits: Preheat the oven to 350°F (180°C). Line a baking sheet with parchment paper.
In a bowl, whisk together the flour blend, salt, pepper, baking powder and baking soda.
Add the vegan butter and mash it into the flour mixture with a pastry cutter.
Add the coconut milk and cider vinegar and blend with a spoon.
Generously flour your working surface.
Roll out the dough to be about ½ an inch thick.
Fold it in thirds and roll out again. Repeat this 2 times. Then cut with a 2 inch biscuit cutter.
Repeat these steps to roll out and cut all of the dough.
Alternatively, use an ice-cream scoop to transfer mounds of the dough 2 inches (5 cm) apart on the prepared baking sheet.
Bake for about 17-20 minutes, or until the biscuits are golden brown and a toothpick inserted into the center of a biscuit comes out clean.
