Beat together the softened butter with the sugars. Add the egg and vanilla and mix well. Start adding the food coloring and continue to mix until you get the color you would like. I used 6 drops red and 24 drops yellow food coloring.
Next, add the flour along with the baking soda and salt. Stir until combined. Finally, fold in the chocolate chips.
Scoop the cookie dough onto a cookie sheet using a large cookie scoop or ice cream scoop. I used about ¼ cup of batter per cookie.
Bake the Trick or Treat Chocolate Chip Cookies for 15 - 18 minutes until done.
