Curdle the milk by adding apple cider vinegar to the plant-based milk.
In a large bowl mix the dry ingredients.
Cube the cold butter, then add it to the dry mixture; you can use a fork or a pastry cutter to combine. The texture should look slightly sandy.
Pour the curdled milk into the dry mixture, slowly, stir gently with a wooden spoon/ spatula until just slightly combined.
Knead the dough on a floured surface. Turn the dough 7 times, very gently. Try not to overwork it.
With a rolling pin, roll the dough out to 2-3 cm thick.
Cut the dough using round dough cutters, place each disk on a baking sheet and brush them on top with olive oil or vegan butter. Put on plant-based cheese and the scallions/onions mixture.
Cook the biscuits in the oven for about 15 minutes until they have doubled in size and are nice and golden.
Remove biscuits from the oven and allow time for them to cool. Once they have warmed, serve immediately. Enjoy!
