Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.

In a medium bowl, whisk together flour, cocoa powder, and baking soda until thoroughly combined.

In a large mixing bowl, cream together butter and sugar until light and fluffy, about 2-3 minutes.

Add egg, vanilla extract, and red food coloring to the butter mixture and mix until fully blended.

Gradually incorporate the dry mixture into the wet ingredients and mix on low speed until just combined.

Using a cookie scoop, portion out the dough onto the prepared baking sheet, spacing them about 2 inches apart.

Bake for 10-12 minutes until the edges are set but the centers are slightly soft.

Let cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.
