Preheat the oven to 350 degrees F. Line a 9 x 9 baking pan with parchment paper and spray with baking spray.

In a small bowl, add the coconut milk and apple cider vinegar. Give it a whirl and set aside while you prep the next ingredients.

In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder and salt.

In a medium sized bowl, add the orange juice, coconut milk, oil, and vanilla. Stir together completely and be sure to scrape the sides of the bowl with a spatula until it is incorporated well. Pour the brownie mixture into the prepped baking pan.

Bake for 25 to 30 minutes or until a skewer inserted in the middle comes out clean and the top is no longer shiny. Good luck in letting it cool before slicing.
