Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a bowl, whisk together flour, baking powder, and salt. Set aside.
In a large bowl, cream together the softened butter and sugar until light and fluffy.
Add the egg, milk, and vanilla extract; mix until combined.
Sift in the cocoa powder, then gradually add the dry ingredient mixture until just combined.
Add a few drops of pink food coloring to the dough; adjust the amount for desired color.
Scoop tablespoon-sized portions of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake for 8-10 minutes, or until the edges are set and the centers are slightly soft.
Remove from oven and let cookies cool on the baking sheets for a few minutes before transferring to wire racks to cool completely.
