Prepare the Cookie Dough:

• Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
• In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt.
• In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
• Beat in the egg, buttermilk, vanilla extract, white vinegar, and red food coloring until well combined.
• Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Bake the Cookies:

• Using a cookie scoop or tablespoon, drop rounded scoops of dough onto the prepared baking sheets, spacing them about 2 inches apart.
• Bake for 9-11 minutes, or until the edges are set.
• Allow the cookies to cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.

Prepare the Cream Cheese Frosting:

• In a medium bowl, beat together the softened cream cheese and butter until smooth and creamy.
• Gradually add the powdered sugar and vanilla extract, continuing to beat until the frosting is light and fluffy.

Assemble the Cookies:

• Once the cookies have cooled completely, spread a generous amount of cream cheese frosting on the top of each cookie.
• For an extra touch, you can sprinkle red velvet cake crumbs or red sprinkles on top.
