How can you make cookies with only three ingredients, you ask? One of the ingredients is cake mix. It's also great, because you can easilly create a different flavour of cookie, by just using a different flavour of mix.
Step 1: Ingredients
1 Box of Cake Mix (I've had good results with the Betty Crocker Variety). You can get any flavour of normal cake mix, but I've found angelfood and Yellow cake to be particularilly delicious.
1/2 Cup Vegetable Oil
(Optional) One jar of Nutella.
That is, if you don't already have them.
You will also need a mixer or a beater and a large bowl, and a cookie sheet.
