Preheat your oven to 350°F (175°C) and grease an 8x8 inch baking pan or line it with parchment paper.
In a large bowl, combine the grated zucchini, coconut sugar, applesauce, almond milk, vegetable oil, and vanilla extract. Mix well until fully combined.
In another bowl, whisk together the flour, cocoa powder, baking soda, baking powder, and salt.
Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix.
If using, fold in the vegan chocolate chips for added richness.
Pour the brownie batter into the prepared baking pan and spread it evenly.
Bake in the preheated oven for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
Allow the brownies to cool in the pan for about 10 minutes before transferring them to a wire rack to cool completely.
Once cooled, cut into squares and serve as a delicious snack!
Notes
You can substitute the coconut sugar with brown sugar if desired.
