1. Preheat the oven to 350°F and line a baking sheet with parchment paper.

2. In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.

3. In a large bowl, beat the butter, granulated sugar, and brown sugar until light and fluffy.

4. Mix in the egg, vanilla extract, and red food coloring until fully combined.

5. Add the dry ingredients to the wet ingredients and mix just until a soft dough forms.

6. Scoop the dough into evenly sized portions and place them on the prepared baking sheet, leaving space between each cookie.

7. Bake for 9 to 11 minutes, until the edges are set and the centers are still soft.

8. Let the cookies cool on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely.

9. To make the frosting, beat the cream cheese until smooth, then mix in the powdered sugar and vanilla extract until creamy.

10. Spread or pipe the frosting over the completely cooled cookies before serving.
