Preheat the oven to 340°F/170°C and line a cupcake pan with paper liners. Set aside.
In a bowl, whisk together the cake flour, salt, baking soda, baking powder, and set aside.
In a large bowl, combine the sugar, mashed bananas, olive oil, non-dairy milk, apple cider vinegar, and vanilla extract. Add the dry ingredients and mix together until just combined.
Divide your batter into the cupcake liners and bake for 18-20 minutes, or until a toothpick inserted comes out clean. Let them cool in the pan for a couple of minutes before transferring them onto a wire rack to cool completely.
