Preheat your oven to 350°F (175°C). Grease and line an 8x8-inch baking pan with parchment paper, leaving an overhang for easy removal.
In a microwave-safe bowl, melt the butter in 30-second intervals until fully melted.
In a mixing bowl, whisk together the melted butter and sugar until well combined.
Add the eggs and vanilla extract to the butter-sugar mixture. Mix until smooth and creamy.
Stir in the cocoa powder, salt, and red food coloring. Mix until the batter turns a vibrant red color.
Gently fold in the all-purpose flour until just combined. Be careful not to overmix.
Fold in the semi-sweet chocolate chips to add an extra layer of chocolatey goodness.
