In a mixing bowl, whisk together the flour, sugar, baking powder, and salt.
In another bowl, combine the almond milk and apple cider vinegar. Let it sit for a few minutes to curdle.
Add the vanilla extract and vegetable oil to the milk mixture.
Pour the wet ingredients into the dry ingredients and mix until just combined. Do not overmix.
Heat a non-stick pan over medium heat. Pour ¼ cup of batter onto the pan for each pancake. Cook until bubbles form on the surface, then flip and cook until golden brown.
