In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon.
In a separate bowl, combine the plant milk, apple cider vinegar, vanilla extract, and oil.
Let the wet mixture sit for 5 minutes to allow the milk to curdle slightly, creating a vegan buttermilk.
Pour the wet ingredients into the dry ingredients and stir gently until just combined - a few lumps are perfectly fine.
Heat a non-stick skillet or griddle over medium heat and lightly grease with oil.
Pour 1/4 cup of batter onto the hot skillet for each pancake.
Cook until bubbles form on the surface and the edges look set, about 2-3 minutes.
Flip and cook for another 1-2 minutes until golden brown.
Transfer to a warming plate while cooking the remaining pancakes.
Serve warm with your favorite toppings.
