I know I’ve been keeping it savory and vaguely healthy this month, but I like to live on the edge. Especially on Saturday nights while wearing my softest/oldest/ugliest/best pajamas and a sweatshirt only the person who bought it in college (12 years ago!) could love.
(With a wardrobe like that, it’s a wonder that I’m single.)
My partying days are well behind me now. I don’t drink or smoke anymore. I quit Diet co*ke completely and have cut my seltzer intake to a maximum of two a day. My coffee…well, that’s neither here nor there.
The point is that my list of vices is pretty short these days, but making myself One Big Chocolate Chip Cookie on the occasional late night is one that I have no intention of parting with. Sometimes you just need a cookie the size of your face. Sometimes it’s the answer to all your problems.
Well, a big cookie and acceptance. Acceptance is a pretty important important part of solving problems.
But this is a baking blog so…back to this big, no-sharing-required dessert for one (or two, if you’re feeling benevolent). It requires miniscule amounts of 8 ingredients that you likely already have, and only about 25 minutes start-to-finish.
This recipe differs drastically from that of my usual Chocolate Chip Cookies. For one, there’s no egg. I have tried many of the single big cookie recipes out there and have always been frustrated by the fact that they require you to scoop one tablespoon of a beaten egg. Have you ever tried to measure a spoonful of beaten egg? It’s stupidly difficult. Also, what do you do with the leftover two tablespoons of beaten egg?!
This is the sort of baking silliness that infuriates me (clearly), so I found a way around it. This recipe mitigates the egg-measuring problem by swapping in one teaspoon of water, and it works incredibly well. I wouldn’t try this for any large-batch cookie recipes, but it works here.
The other differences from my regular recipe are less…scientific. I use melted butter here because creaming one tablespoon of butter is ridiculous and unnecessary. Oh, and there’s no need to chill your dough. This recipe is meant to be made on the fly and enjoyed while the chocolate is still melty.
Melted chocolate + soft centers + chewy caramelized edges = ❤ ❤ ❤ 
A quick word about leaveners before I get to the recipe. I tested this recipe seven times (!) with both baking soda and baking powder. Baking soda, which I use in my large-batch recipe because it produces browner cookies with more surface area, won out, but just barely.
Generally speaking, baking soda and baking powder are not interchangeable, but this is one recipe where you can use either one (in a 1/8 teaspoon volume) and still have a quality cookie. The baking powder version will be a bit thicker and won’t have the same dark, buttery edges as the baking soda version, but it will still be delicious. This soda/powder swap will not work for many (if any) other recipes, but it works here. I thought about leaving this information out of this post, but I don’t want a lack of leavener to come between you and a cookie the size of your face.
Thank me later.
One Big Chocolate Chip Cookie
makes 1 large cookie
1 tablespoon unsalted butter, melted
2 tablespoons light or dark brown sugar, packed
1 teaspoon water (not cold)
1/8 teaspoon pure vanilla extract
3 tablespoons all-purpose flour
1/8 teaspoon baking soda*
pinch of Kosher or sea salt
2 tablespoons semisweet chocolate chips, plus more for optional topping
Preheat oven to 350F. Line a baking sheet with parchment. Set aside.
In a small bowl, use a fork to whisk together melted butter and brown sugar. Mix in water and vanilla. Add flour, baking soda and salt, and whisk until a dough forms. Use a silicone spatula or spoon to mix/fold in chocolate chips.
Use your hands to form dough into a ball and place on parchment. Dot with additional chocolate chips (for aesthetic purposes), if desired. Press down on dough ball slightly with the heel of your hand, so that it’s more of a disk/puck and less of a ball. Bake for 14-16 minutes or until edges have darkened to a golden brown color and center is still a bit pale.
Let cookie cool on the pan for 5-7 minutes before using a spatula to remove it to a plate. Enjoy.
Note:
An equal volume of baking powder will work in place of baking soda. The cookie it produces will be a bit thicker and paler, but still delicious. I do not recommend swapping baking soda and baking powder in any other recipes.
