Last week, I needed a win. I needed a win badly.
I was reeling from a personal tragedy, having a difficult time getting myself out of bed in the morning, and couldn’t get any recipes to work properly. I suffer from depression and anxiety, so some of this is just part of my normal life, but there’s something about having recipes—something with which I am supposed to have some modicum of talent and control—repeatedly fail that sends me into a tailspin.
Exhibit A: That time I obsessively made 18 babkas.
I woke up Friday morning determined to get one recipe to work. Just one. Something I thought would be easy and only take two or three tries: a chocolate variation on my single-serving One Big Chocolate Chip Cookie. Using that recipe as a guide, I started mixing…and then proceeded to have many, many fails.
Over the course of two hours, I ran the gamut of cookie failure. Too flat, too puffy, too dry, too chemical-tasting—you get the idea. Here are four of them:
But then I looked at my tried & true Double Chocolate Cookie recipe and realized I hadn’t tried blooming the cocoa, a method of heating it with butter and sugar that produces a richer chocolate flavor. As with the large-batch cookies, this quick and easy process turned out to be key to my One Big Chocolate M&Ms Cookie success!




Also, crucial to cookie success? Underbaking. If you bake this cookie until it’s fully done, you’ll end up with a chocolate M&Ms frisbee. This is because cocoa powder tends to dry things out and also because I use a teaspoon of water here in place of the usual egg (a little trick I learned from the regular chocolate chip version). Underbaking will yield crisp-chewy edges, a crackly top, and a soft, fudgy center. Yesssss.
I had a bunch of M&Ms leftover from making Monster Carmelitas last month, so that’s what I chose to use as my cookie mix-in. I love the contrast of the melty chocolate centers, crispy candy shells, and brownie-like cookie, but feel free to put whatever you want into this cookie base. Regular semisweet chocolate chips, white chocolate, mini peanut butter cups, walnuts—whatever you have around. It’s almost certainly guaranteed to be a win. And really, when is a big cookie not a win?
One Big Chocolate M&Ms Cookie
makes one large cookie
1 tablespoon unsalted butter
1 tablespoon natural unsweetened cocoa powder
2 tablespoons light brown sugar, packed
1 teaspoon water (not cold)
1/8 teaspoon pure vanilla extract, optional
2 tablespoons + 1 teaspoon all-purpose flour
1/8 teaspoon baking soda
pinch of Kosher or sea salt
2 tablespoons M&Ms candy
Preheat oven to 350F. Line a baking sheet with parchment. Set aside.
In a small bowl, combine butter, cocoa powder, and brown sugar. Microwave in 15-second increments, stirring in between until melted together. Alternatively, you may do this in a saucepan on the stove over medium-low heat.
Mix in water and vanilla. Add flour, baking soda and salt, and whisk with a fork until a soft dough forms. Use a silicone spatula or spoon to mix/fold in M&Ms.
Use your hands to form dough into a ball and place on parchment. Dot with additional M&Ms (for aesthetic purposes), if desired. Bake for 12-13 minutes or until the top is crackly and the cookie appears a bit underdone.
Let cookie cool on the pan for 5-7 minutes before using a spatula to remove it to a plate. Enjoy.


I know I’ve been keeping it
My partying days are well behind me now. I don’t drink or smoke anymore. I quit Diet Coke 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.
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 
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.
Thank me later.
