In a mixing bowl, whisk together the flour, coca powder, baking soda and salt. Set aside.
In a separate large mixing bowl, beat together the butter, brown sugar and granulated sugar with a hand held mixer or stand up mixer until creamy (approximately 3-4 minutes).
Add in the 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 the red food coloring and stir until the dough is a dark vibrant red color.
Stir the chocolate chips into the batter 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 size cookie scoop (approximately 1.5 tablespoons) to place the cookie dough on baking sheets spaced approximately 2-3 inches apart to allow room for the cookies to spread.
Bake for 10-13 minutes until the edges of the cookies are set. The center of the cookies will still look undercooked but the cookies will continue to cook as they set.
Let the cookies sit on the baking sheet for at least 5 minutes and then move them to wire racks to cool completely.
Then the cookies are ready to 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.
