Deep Dish Chocolate Chip Cookie Pie
Adapted from eat live run
(I changed things around a bit)

2 sticks unsalted butter, softened
1 cup light brown sugar
1 cup granulated sugar
2 large eggs
1 egg yolk
1 & ½ ts pure vanilla extract
2 1/2 cups all purpose flour
1 ts baking soda
1 ts salt
1 & ½ cups semisweet chocolate chips

Cook notes: if you don’t have a cast iron, you can easily put this in little ceramic ramekins.  Just don’t preheat at 400, only preheat at 325 degrees. Make sure you use a clean cast iron; we don't want your cookies tasting like dinner. *Cooking times vary GREATLY!  Please check at the 25 minute mark!

Preheat oven to 400 degrees.
Grease up your cast iron skillet with cooking spray.
In a medium bowl, whisk the flour, salt and baking soda.
Cream the butter and sugars together.  Add in eggs plus egg yolk, then mix.   Add in vanilla and mix until just combined.  Add in your dry ingredients, mix, then add in the chocolate chips.

Press the cookie dough down into your greased skillet evenly; using wet hands make sure the corners are good and even with dough.
Place in preheated 400 degree oven, then turn temp down to 325 degrees and bake for about 25-40* minutes. Might want to rotate pan halfway thru baking.
You are looking for golden brown edges and slightly cakey crumbs come thru when a cake tester is used.
Make sure to let this rest for at least an hour before slicing.
