In a large mixing bowl, whisk together barley flour, oat flour, baking powder, and salt.
In a medium mixing bowl, whisk together nonfat milk, eggs, light olive oil, clear honey, and vanilla extract.
Add wet ingredients to dry, and whisk until just combined.
Heat a large non-stick skillet over low-medium heat.
Pour about 3 tablespoons of batter (per pancake) into hot skillet and cook until bubbles begin to appear on top, and the bottom is golden brown; then flip pancake/s and cook until other side is also golden brown (adjusting heat as necessary to keep pancake/s from burning).
