Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a medium bowl, whisk together flour, cocoa powder, baking soda, and salt.
In a large bowl, cream the softened butter and granulated sugar until light and fluffy.
Add the egg, red food coloring, and vanilla extract to the butter mixture, mixing until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Scoop the dough onto the prepared baking sheet, spacing them at least 2 inches apart.
Bang the baking sheet against the counter to create those signature pan-banging cookies.
Bake for 12-15 minutes, or until the edges are set but the centers are slightly soft.
While the cookies cool, prepare the cream cheese drizzle by beating the softened cream cheese and powdered sugar until smooth.
Drizzle the cream cheese mixture over the cooled cookies and allow to set before serving.
