Preheat oven to 375° and place your oven rack on the lowest level. Lightly butter the inside of a 9 or 10 inch cast iron skillet. You can use a larger or smaller one, if that’s what you have, but you’ll have to adjust your cooking time accordingly. I’ve only made this using my 9 inch pan 😬
Get all your ingredients together so we don’t get halfway through and find out we’re missing something 🙄.
In a medium bowl, mix your sugars and your softened butter together with either a wooden spoon or a hand mixer until fully combined. There’s no need to cream the butter and sugar together like you would in actual cookies. Yay!!
Add in your one egg, egg yolk, and vanilla extract or paste. Whichever you have. I had paste, so I used it. Combine completely. Isn’t this easy?
Now stir in your flour, salt, and baking soda until combined no streaks are left. We want the flour fully incorporated, but don’t overmix it. When you don’t see any more white bits, you’re done.
Fold in all but about 1/4 cup of your chocolate chunks. We’ll save a bit to sprinkle over the top before baking. It makes it look really pretty! I chopped mine up a bit so that there would be different sized bits of chocolate all over the pie 😋
I have a culinary quirk. I use a rice paddle for a lot of non-rice kitchen activities, especially folding ingredients. I find its short handle and wide face gives me more control over whatever I’m working with, whether hot or cold foods. I use it when tossing pasta, a salad, or folding in chocolate chips. Like I said, quirky, but really effective. Just “tossing” that out there 😉
Spread the cookie dough all the way to the edges of your buttered pan. Lightly wetting your hands will help you spread the dough without it sticking all over you, forcing you to repeatedly lick the dough off your hands. Not sanitary. Cookie for one? Do you.
Sprinkle the remaining chocolate chunks over the top of your dough and finish with a sprinkling of flaky sea salt. Bake at 375° for 25-30 minutes or until the center is set.
Resist the urge to cut into the cookie pie for about an hour. I know, that’s asking a lot, but try.
I cut mine into wedges. Pie style. If you want, plop some ice cream in the middle and get to it. I do not judge.
