Preheat your oven to 350°F (177°C) and line two baking sheets with parchment paper.

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

In a large mixing bowl, beat the butter and sugar together until light and fluffy. Add the egg, vanilla extract, and red food coloring and mix well.

Gradually add the flour mixture to the butter mixture and mix gently until just combined.

Scoop out dough onto prepared baking sheets, spacing 2 inches apart, and gently flatten each scoop.

Bake for 10-11 minutes until slightly puffed and the edges look set but centers remain soft.

Allow the cookies to cool for a few minutes on the baking sheet before transferring to a wire rack.

Beat the cream cheese and butter until smooth. Gradually add powdered sugar and mix until fluffy.

Spread the cream cheese frosting on cooled cookies using an offset spatula.

Optionally, sprinkle colorful decorations on top of the frosted cookies while the frosting is wet.
