Pre-heat a non-stick griddle or large pan to medium-high heat, and coat with butter substitute or oil. I coat with plant butter even if I'm using a non-stick pan for taste!
In a large bowl, whisk together the flour, sugar, baking powder, and salt
Add milk substitute, oil, egg, and vanilla extract, and whisk until smooth (some lumps are ok)
Pour about 1/3 cup or batter on to the pan for each pancake - the batter pours out really thick so you'll need to pour slowly! Cook until bubbles are visible, flip, and cook about 2 minutes on the other side
Repeat until the batter is all used
