Place the yellow cake mix in a large mixing bowl.
In a different bowl, beat the eggs, add milk and vanilla extract and mix together.
Pour this wet ingredients mixture to the dry cake mix in the other bowl and mix well to combine using a spoon.
Also add the oil and chocolate chips, knead well to form the cookie dough. Let this cookie dough chill in the refrigerator for about an hour.
To bake the cookies:
Preheat the oven to 350 degree Fahrenheit.
Prepare a baking sheet lined with parchment paper.
Scoop out a tablespoon of cookie dough and place it in the baking sheet. Similarly, do more and place 8 cookies at a time in the baking sheet, with enough space between.
Bake in the preheated oven for about 12 minutes until the cookies are done!
Once the cookies are baked (they will be very soft in texture at this point, but they will become the right texture as the cool down) immediately transfer from the hot oven and allow the cookies to cool down slightly.
Chill the remaining dough if not using right away, otherwise you can bake the remaining cookies in a second batch!
Enjoy the warm, soft, cakey yellow cake mix cookies with a cup of milk, coffee or tea!
