To make cookies with boxed cake mix, add 2 eggs,1/3 cup of oil and 1/4 cup of water to the dry mix, and bake the mixture for 10 minutes at 350 degrees Fahrenheit. Additional ingredients, such as nuts, can be added to the cookies before baking.
To make cookies from a boxed cake mix, combine 1 box of any flavor cake mix with 2 eggs, 1/3 cup of oil, such as vegetable oil or melted butter, and 1/4 cup of water. Beat the mixture until it is smooth, and form the dough into 1 inch balls. Flatten each ball by pressing on it with the bottom of a glass that has been coated in flour, and place the flattened cookie on the cookie sheet. Allow space between each teaspoon of dough for the cookies to spread while baking.
Allow the cookies to bake for 10 minutes at 350 degrees Fahrenheit. Remove the cookies from the oven, and allow the cookies to cool. Adjust the temperature as needed when using a dark or non-stick pan. The center of the cookies should be soft after baking, as the cookie continues to set during the cooling period. Additional ingredients, such as chocolate chips, nuts or dried fruits, can be added to the mixture before baking the cookies.
