Preheat your oven to 350°F (175°C).
In a bowl, whisk together the flour, cocoa powder, baking soda, and salt.
In a separate large bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add the egg, vanilla extract, and red food coloring to the butter-sugar mixture, mixing until combined.
Gradually add the dry ingredients to the wet mixture, mixing just until combined.
Fold in the white chocolate chips gently.
Scoop tablespoonfuls of dough onto a lined baking sheet, spacing them 2 inches apart.
Bake for 10-12 minutes or until the edges are set and the tops look slightly glossy.
Remove from oven and let cool on the baking sheet for a few minutes before transferring to a wire rack.
