Preheat oven to 350°F (175°C) and grease a baking pan.
In one bowl, whisk together flour, cocoa powder, sugar, and a pinch of salt.
In another bowl, mix vegetable oil, eggs, vanilla extract, and red food coloring until blended.
Gradually fold dry ingredients into wet mixture until just combined; avoid overmixing.
Pour batter into the prepared pan and bake for 25-30 minutes or until a toothpick comes out clean with moist crumbs.
While cooling, whip up the frosting by mixing cream cheese and powdered sugar until fluffy. Spread over slightly warm brownies.
