Most cookie recipes assume you want two dozen. You probably don’t. You want one cookie, still warm, with chocolate soft enough to smear, and you want it tonight without a bowl of leftover dough sitting in the fridge.
That’s the whole idea behind this single serving chocolate chip cookie. Think of it as a small batch chocolate chip cookie scaled all the way down: it takes one small bowl and a spoon. There’s no mixer, no creaming, and no waiting around for butter to soften. If you have flour, sugar, butter, an egg and a handful of chocolate chips, you’re about twenty minutes from eating.
The full recipe is just below. After it you’ll find what the dough should look like, a few small tricks that change the result, and a troubleshooting section for the usual problems like flat, dry or cakey cookies.
Why This Single Serve Cookie Works
You can’t just shrink a regular cookie recipe into a single serve cookie. One that makes 24 cookies uses two eggs, so a single cookie would need a twelfth of an egg, and nobody can measure that. Everything else gets awkward too, which is why most “halved” recipes come out strange.
This version was built for one cookie from the start, and four choices do most of the work:
- Only the egg yolk. The yolk brings fat and richness, which makes the cookie chewy and tender. The white would make it puffier and drier.
- Melted butter. It gives a denser, chewier cookie than creamed butter, and you can start mixing right away.
- More brown sugar than white. Brown sugar holds on to moisture, so the middle stays soft after the edges crisp up. The little bit of white sugar helps those edges brown.
- A small pinch of baking soda. Just enough to help the cookie spread and color, not enough to turn it into a puffy, cakey one.
When a Single Cookie Makes Sense
A full batch has its place, like an easy dump cake for a family dinner, but plenty of the time it’s the wrong call. Maybe you live alone and want a cookie for one, or the rest of the household isn’t interested tonight. Maybe it’s late, the bakery is closed, and you only want something small and sweet. A single serving chocolate chip cookie also takes the pressure off: there’s no dozen sitting on the counter that you feel obliged to finish before it goes stale, and there’s only one bowl to wash.
It’s also a good way to test an idea. If you want to know whether cocoa or peanut butter chips work in your dough, make one cookie first and decide afterwards whether a whole batch is worth it.
Ingredients
- 2 tablespoons (28 g) unsalted butter, melted
- 1½ tablespoons (20 g) packed brown sugar
- 1 tablespoon (12 g) granulated sugar
- 1 egg yolk
- ¼ teaspoon vanilla extract
- ¼ cup plus 1 tablespoon (about 40 g) all-purpose flour
- ⅛ teaspoon baking soda
- A pinch of salt
- 2 tablespoons (about 30 g) chocolate chips, plus a few more for the top
A few notes on the ingredients. Use real vanilla if you have it, because there’s very little else going on in the dough. Semi-sweet chips are the classic choice, but a chopped chocolate bar melts into nicer puddles. If your butter is salted, leave out the pinch of salt.
Instructions
- Heat the oven. Set it to 350°F (175°C) and line a small baking tray with parchment paper.
- Mix the butter and sugars. Melt the butter in a small bowl (about 20 seconds in the microwave) and let it cool for a minute so it doesn’t cook the yolk. Stir in both sugars until the mixture looks glossy and a little wet.
- Add the yolk and vanilla. Stir until smooth and slightly lighter in color.
- Add the dry ingredients. Sprinkle in the flour, baking soda and salt. Stir only until you can’t see dry flour, then stop. Extra mixing makes the cookie tough.
- Fold in the chocolate. The dough will be thick and a bit sticky, closer to a paste than something you could knead.
- Shape and press. Roll the dough into a ball, set it on the tray, and flatten it gently to about ½ inch (1 cm) thick. Press a few extra chips into the top.
- Bake. Bake for 12 to 14 minutes, and start checking at 11. You want golden edges and a middle that still looks slightly underdone.
- Wait five minutes. Leave the cookie on the tray. It keeps setting as it cools, and this short wait is the difference between a gooey center and a raw one.

What the Dough Should Look Like
Before you bake, check the dough. It should be thick and a little sticky, hold together when you roll it, and leave only a bit of residue on your fingers. If it crumbles apart, stir in 1 teaspoon of milk. If it sticks to your hands badly, chill it for 10 minutes instead of adding more flour. Extra flour is the most common reason these cookies come out dry.
Tips for the Best Cookie
- Measure the flour carefully. Spoon it into your measuring spoons and level it off with a knife. Scooping straight from the bag packs in more flour than you think.
- Take it out early. Pull the cookie when the center still looks soft. The tray’s heat finishes the job.
- Let the butter cool slightly. Hot butter makes the dough greasy and the cookie spread too thin.
- Chill for a thicker cookie. Fifteen minutes in the fridge helps the dough keep its shape in the oven and deepens the flavor.
- Try browned butter. Cook the butter in a small pan until it smells nutty, then let it cool for a few minutes. Browning cooks off a little water, so add 1 teaspoon of milk to the dough.
- Finish with flaky salt. A few flakes right out of the oven make the chocolate taste richer.
- Use a toaster oven if you have one. It saves heating a full oven. Check it a minute or two early, since small ovens run hot.
Common Problems and Fixes
The cookie spread too thin. The butter was probably too warm, or the flour was under-measured. Cool the butter, chill the dough for 15 minutes, and check that your baking soda isn’t old.
It came out dry or crumbly. Too much flour is almost always the cause. Spoon and level next time, and add a teaspoon of milk if the dough looks sandy.
It tastes cakey. Overmixing, extra flour or a whole egg can all do this. Stick to the yolk and stir just until the flour disappears.
It went hard once it cooled. It was baked a little too long. Take it out while the center still looks soft and let it finish on the tray.
The top looks pale and dull. It needs a minute or two more in the oven, or your sugars were measured light. Look for golden edges rather than watching the clock.
The bottom burned. Dark baking trays absorb more heat. Use parchment, put the tray on the middle rack, and lower the temperature by 25°F if your oven runs hot.
Easy Variations
- Double chocolate: Replace 1 tablespoon of the flour with unsweetened cocoa powder.
- Peanut butter chip: Swap the chocolate chips for peanut butter chips.
- Oatmeal chocolate chip: Replace 2 tablespoons of the flour with quick oats.
- Nutty: Stir in 1 tablespoon of chopped walnuts or pecans.
- Brown butter and sea salt: Use browned butter (see the tips above) and finish with flaky salt for a more grown-up cookie.
What to Serve It With
Warm from the oven, this cookie is hard to beat with a cold glass of milk. A scoop of vanilla ice cream on the side turns it into a proper dessert, because the ice cream melts into the soft center. It also makes an easy ending to a no-fuss dinner like this one pan chicken and rice, when you want dessert without baking a whole tray. If you’re pairing it with coffee or tea, wait out the full five minutes first. Melted chocolate stays hot longer than the cookie around it.
Storage
The cookie is best eaten warm, but leftovers keep in an airtight container at room temperature for up to 2 days. If you want a fresh one later, wrap the shaped, unbaked dough ball and refrigerate it for up to 2 days, then bake it straight from the fridge and add a minute or two. This dough contains a raw egg yolk, so bake it before eating.
Final Thoughts
This single serving chocolate chip cookie is the easiest way I know to satisfy a cookie craving without committing to a full batch. If you have never baked a cookie for one before, this is a good place to start. The dough comes together in minutes, the oven does the rest, and you end up with a soft center and golden edges. Make it once as written, then play with the variations.
FAQs
Can I make this without an egg yolk?
Yes. Replace the yolk with 1 tablespoon of milk. The cookie will be a little less rich and slightly more cake-like, but it still works.
Can I use a whole egg instead of the yolk?
Not a whole one, since that’s far too much liquid for one cookie. Beat an egg and use about 1 tablespoon of it. You can save the rest for scrambled eggs.
Can I make this in the microwave?
You can mix the dough the same way, but a microwave won’t give you crisp edges, and the texture ends up closer to a mug cake. For a real cookie, use the oven or a toaster oven.
Can I make two smaller cookies?
Yes. Divide the dough in half, shape two rounds and bake for 9 to 11 minutes. Leave a couple of inches between them.
What can I use instead of all-purpose flour?
A gluten-free 1-to-1 baking blend works well. Results vary a little between brands, so go by the look of the dough rather than the exact measurement.
