Preheat your oven to 350°F (175°C) and prepare a 9×13 inch baking pan by greasing or lining it with parchment paper.

In a medium bowl, whisk together all-purpose flour, unsweetened cocoa powder, baking powder, and salt.

In a large mixing bowl, combine melted unsalted butter and granulated sugar until smooth, then add eggs one at a time, followed by vanilla extract and red food coloring.

Gradually add the dry ingredients to the wet ingredients and mix until just combined, then fold in dark chocolate chips.

Pour the brownie batter into the prepared baking pan and spread evenly.

Bake for 25-30 minutes or until a toothpick inserted in the center comes out with a few moist crumbs.

Allow to cool completely in the pan before cutting into squares.
