In a large bow, whisk together the flours, baking powder, salt, and sugar if using.

Add chilled olive oil and using a fork or your hands, rub it into the flour until the mixture is crumbly.

Pour in the cold non-dairy milk or buttermilk and, using a wooden spoon, stir until a dough forms (add a bit more milk if it’s too dry).

Turn dough out on to a clean, lightly floured surface. Roll dough (or press with fingers) until it is in a 1- inch thick rectangle.

Use biscuit cutter (or jar or cup) to cut biscuits into desired size and shape OR use a tablespoon to make drop biscuits.

Place biscuits on the baking sheet, place in the oven, and bake for about 10-15 minutes, until lightly browned. Remove from oven and let sit on sheet for 5 minutes. Serve slightly warm.
