First you need a big bowl.
Next add some butter. Make sure it is soft by tasting it. Then mix it with some sugar and eggs until it's fluffy.
Next, eat some chocolate chips, add a spoonful of something...
Ya, that's the right one! Mix the dough with your hands
Make sure you put flour all over your head so everyone knows you helped.
And all over your shirt, so everyone knows how hard you worked on the cookies.
Lastly, marvel at the amazingness of it all. Then, try to snitch one before they are cooked and mom takes you away for a bath. Yay for cookies!
