Preheat your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
In a large mixing bowl, combine the flour, cocoa powder, sugar, baking soda, and salt. Whisk until completely mixed.
In another bowl, mix together the vegetable oil, vanilla extract, almond milk, and apple cider vinegar. Let it sit for a few minutes—this will help create a fluffier texture.
Pour the wet ingredients into the dry ingredients and stir until just combined. Be careful not to overmix. Fold in the dairy-free chocolate chips if using.
Divide the batter evenly among the cupcake liners, filling each about two-thirds full.
Bake in the preheated oven for 18-20 minutes or until a toothpick inserted in the center comes out clean.
Allow the cupcakes to cool in the tin for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Dust with powdered sugar or top with vegan frosting and sprinkle with chocolate shavings for an elegant touch.
