Preheat the oven to 350 and spray two cookie sheet with cooking spray or line with silicone baking liners.
In a large bowl, mix together the cake mix, eggs and oil until well blended. I prefer to use a wooden spoon for this recipe and not get out the mixer.
Stir in all the kinds of the chocolate chips, gently, until well mixed.
Drop heaping tablespoons of dough onto the cookie sheets, spacing them about 2 inches apart.
Bake for 8 to 10 minutes or until the cookies just set in the middle. You can also rotate the cookie sheets half-way through the cooking time for even baking.
Allow cookies to cool for about 5 minutes before moving to wire racks to cool completely.
Notes
You can store these cookies, for about 5 days, in an air tight container and at room temperature.
