Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper.
In a mixing bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set aside.
In another large bowl, cream the softened butter and granulated sugar together using an electric mixer until light and fluffy.
Add the egg, red food coloring, and vanilla extract to the butter mixture. Mix until well combined.
Gradually add the dry ingredients to the wet ingredients, mixing until just combined. If desired, fold in the white chocolate chips.
Using a cookie scoop or spoon, drop rounded tablespoons of dough onto the prepared baking sheet, spacing them about 2 inches apart.
Bake in the preheated oven for 10-12 minutes or until the edges are set but the centers are still soft.
Remove from the oven and allow the cookies to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
Once cooled, pipe or spread cream cheese frosting on top of each cookie if desired.
