Preheat your oven to 350 degrees Fahrenheit. Line an 8×8-inch baking pan with parchment paper, allowing some to hang over the edges for easy removal later.
In a medium mixing bowl, combine all your dry ingredients: flour, cocoa powder, baking powder, and salt. Whisk them together thoroughly to ensure an even mix.
In another bowl, mix all your wet ingredients: melted coconut oil, milk, egg, and vanilla extract. Stir well until fully combined.
Pour the wet mixture into the bowl of dry ingredients. Stir until just combined; don’t overmix, as this could lead to tough brownies.
Fold in half a cup of semi-sweet chocolate chips into the brownie batter, incorporating them evenly.
Transfer the brownie batter to the prepared baking pan, spreading it out evenly using a spatula.
Sprinkle the remaining chocolate chips over the top of the batter, adding a decadent touch.
Bake in the preheated oven for 40 to 45 minutes. Check for doneness by inserting a toothpick into the center; it should come out with a few moist crumbs.
Once baked, remove the pan from the oven and allow the brownies to cool for at least five minutes in the pan.
Using the parchment paper, lift the brownies from the pan and place them on a wire rack to cool completely before cutting into squares and enjoying!
