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

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

In a large mixing bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.

Add in the egg and vanilla extract, mixing until fully incorporated and smooth.

Gradually add the dry flour mixture to the wet ingredients, mixing until just combined.

Gently fold in the cherries and chocolate chips until evenly distributed.

Using a tablespoon or cookie scoop, drop portions of dough onto the lined baking sheets, spacing them about 2 inches apart.

Bake the cookies for 10-12 minutes until edges are set and centers look slightly underbaked.

Allow the cookies to cool on the baking sheets for approximately 5 minutes before transferring to a wire rack.
