Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a medium bowl, whisk together the all-purpose flour, cocoa powder, baking powder, and salt. Set aside.
In a large bowl, combine the melted vegan butter, brown sugar, and granulated sugar. Mix well until smooth and creamy.
Add the unsweetened almond milk and vanilla extract to the sugar mixture. Stir until fully combined.
Gradually add the dry ingredients to the wet mixture, stirring gently until incorporated. Be careful not to overmix.
Fold in the vegan chocolate chips until evenly distributed throughout the dough.
Using a tablespoon or cookie scoop, drop rounded portions of the dough onto the prepared baking sheet, leaving space between each cookie.
Bake in the preheated oven for 10-12 minutes, or until the edges are set but the centers remain slightly soft.
Remove from the oven and allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
