Preheat your oven to 350 degrees F, line a 12 muffin tin with muffin liners and set aside.
In a large bowl whisk together your flour, sugar, brown sugar, baking powder, and salt.
In a measuring cup, measure your soy milk. Add your apple cider vinegar and vanilla extract into your measuring cup and give it a quick whisk.
Pour your soy milk mixture into your flour mix and mix until just combined. Fold in your vegan chocolate chips.
Fill your muffin liners with your muffin batter about 3/4 full. Bake for 20-25 minutes or until a toothpick inserted into one muffin comes out almost clean.
Allow to cool for 5 minutes in the muffin tin before transferring to a cooling rack to cool completely, enjoy!
