In a small bowl, thoroughly mix together the ground flaxseeds and warm water for 5 minutes. Set aside.
In a large bowl, combine the flour, sugar, salt, and baking powder and mix well. Form a well in the flour mixture and add the vegetable oil, flax meal mixture, plant-based milk, vanilla extract, and grated zucchini. Gently mix together.
Fill your cupcake tin with batter (filled to the top).
