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

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

In a large mixing bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy, about 3 minutes.

Beat in the egg and vanilla extract until fully incorporated, scraping down the sides of the bowl as needed.

Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Fold in the dried cherries and dark chocolate chunks by hand.

Scoop rounded tablespoons of dough onto the prepared baking sheets, spacing them 2 inches apart.

Bake for 10-12 minutes, or until the edges are set but the centers remain slightly soft. Cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
