In a mixing bowl, whisk together all purpose flour, unsweetened cocoa powder, baking soda, and salt. Set aside.
In a separate large mixing bowl, beat together unsalted butter, light brown sugar, and granulated sugar with a mixer until creamy (approximately 3-4 minutes).
Add in eggs and vanilla extract and mix until combined and creamy.
Slowly stir the dry ingredients into the wet ingredients on low speed until just combined. Be careful not to over mix the batter.
Add in red gel food coloring and stir until the dough is a dark vibrant red color.
Stir in white chocolate chips by hand.
Cover and refrigerate the dough for 30-60 minutes (but not longer than 2 hours).
Preheat the oven to 350 degrees Fahrenheit.
Use a medium cookie scoop (approximately 1.5 tablespoons) to place the dough on baking sheets spaced 2-3 inches apart.
Bake for 10-13 minutes until the edges are set. The centers will look slightly undercooked but will continue to set.
Let the cookies sit on the baking sheet for at least 5 minutes, then transfer to wire racks to cool completely.
Serve and enjoy.
Notes
Store the cookies in an airtight container at room temperature for up to 5 days. Place a piece of bread in the container with the cookies to keep them soft. Make sure all your cold temperature ingredients are at room temperature before making the cookie dough to ensure that they combine evenly.
