Back To School Giant Cookie

Evin just started kindergarten and I made this for him for his very first ever day of school. It was a big hit.

Back to School Giant Cookie
(adapted from a recipe from How Does She found on Pintrist)

2 sticks butter
¾ cup brown sugar
¾ cup white sugar
Mix, then add-
2 eggs
1 tsp vanilla
1 tsp water
Mix, then add-

1 tsp salt
1 tsp baking soda
1 ½ cups flour
2 cups oatmeal
½ bag chocolate chips
(or 3/4 of the bag, or the whole thing. You know you want to!)
-Dough will be very sticky!-
plop onto pizza pan
Spread out evenly onto a round pizza pan, then put pizza pan on a large cookie sheet so as to catch any dough that might fall off to the bottom of your oven making a mess (based on experience).
Bake at 350 for 15-20 minutes and check every so often to make sure it doesn’t get over cooked. In some ovens it may even take 25 minutes or so. Just keep an eye on it.
