Preheat your oven to 350°F (175°C) and line a cupcake tin with liners.
In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
In another bowl, mix the almond milk, vegetable oil, apple cider vinegar, and vanilla extract.
Pour the wet ingredients into the dry ingredients and mix until just combined.
Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
Let the cupcakes cool in the tin for a few minutes, then transfer to a wire rack to cool completely.
