This easy single serving chocolate chip cookie recipe makes one large, soft-centered cookie in about 15 to 30 minutes, including optional chilling time. You only need 1 tablespoon of melted butter, two sugars, one egg yolk, a small amount of flour, and chocolate chips, so it is perfect when you want a fresh homemade cookie without making a full batch.
The cookie has lightly crisp golden edges, a tender middle, buttery brown-sugar flavor, and pockets of melted semisweet chocolate. It is mixed in one small bowl, shaped as one thick mound, and baked at 350°F (175°C) for 10 to 12 minutes.

Ingredients You’ll Need
Each ingredient has a specific job in this carefully scaled cookie dough. Measuring accurately matters because small changes are more noticeable when the recipe makes only one cookie.
- Butter: Use 1 tablespoon of unsalted butter, melted and briefly cooled. Unsalted butter lets you control the tiny amount of salt added to the dough.
- Sugars: One tablespoon each of granulated sugar and packed light brown sugar balances crisp edges with a soft, flavorful center.
- Egg yolk: Use one large egg yolk, about 18 grams, and do not add the white. The yolk contributes richness and binding without the extra liquid that can make a single cookie cakey or overly thin.
- Vanilla: Just 1/4 teaspoon adds a gentle bakery-style aroma and rounds out the chocolate flavor.
- Flour: Use 1/4 cup of all-purpose flour, approximately 30 to 32 grams. Spoon it into the measuring cup and level it, or weigh it for the most reliable result.
- Leavening and salt: A small 1/8 teaspoon of baking soda and approximately a 1/16 teaspoon pinch of salt are all that is needed.
- Chocolate chips: Two tablespoons, or about 20 to 25 grams, of semisweet chocolate chips provide generous chocolate in every bite.
How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then line a small baking sheet with parchment paper. The parchment prevents sticking and makes cleanup especially easy for this quick dessert.
Step 2: Melt 1 tablespoon of unsalted butter and let it cool briefly until it is warm rather than hot. Hot butter can make the sugar mixture loose and may partially cook the egg yolk when it is added.
Step 3: Stir the melted butter with the granulated sugar and packed light brown sugar. Mix until the sugars are moistened and the mixture looks evenly combined rather than lumpy.
Step 4: Add the large egg yolk and 1/4 teaspoon vanilla extract. Stir until smooth, taking a moment to blend the yolk completely into the buttery sugar mixture.
Step 5: Add the all-purpose flour, baking soda, and small pinch of salt. Stir only until no dry flour remains, because overmixing can make the cookie less tender.
Step 6: Fold in the 2 tablespoons of semisweet chocolate chips. Use a gentle motion so the chips stay distributed throughout the small amount of dough.
Step 7: Place the dough on the parchment-lined baking sheet and shape it into one thick mound. If the dough seems very soft, or if you want a thicker cookie, chill the shaped mound for 10 to 15 minutes before baking.
Step 8: Bake for 10 to 12 minutes. Look for edges that are set and lightly golden, while the center should still look slightly soft rather than completely firm.
Step 9: Leave the cookie on the baking sheet for 5 to 10 minutes before eating. The residual heat finishes the center, and the cookie firms as it cools.
Pro Tips for the Best Single Cookie
The most important rule is to use only the egg yolk. A whole egg contains too much liquid for this one-cookie dough and can lead to a cakey texture or excessive spreading.
Pay attention to the butter temperature. Warm butter is fine, but fully cooled melted butter gives you more control over spreading. When the dough is especially soft, chilling the shaped mound for 10 to 15 minutes helps it hold a thicker shape in the oven.
Do not wait for the center to look completely baked. The cookie continues cooking from residual heat after it leaves the oven, so taking it out when the middle is slightly underbaked is the best way to keep it soft.
For an attractive finish, reserve a few of the chocolate chips and press them gently onto the top of the dough mound before baking. This is optional, but it gives the finished cookie a bakery-style appearance.
Serving Ideas and Texture Variations
Enjoy the cookie warm after its brief cooling time, when the chocolate chips are still soft and the center has a rich, tender texture. A glass of cold milk, a cup of coffee, or a scoop of vanilla ice cream makes an easy pairing.
For a thicker cookie, cool the butter completely and chill the shaped dough before baking. For a slightly more spread-out cookie, skip the optional chill and shape the dough into a somewhat lower mound, while still watching the edges and soft center closely.
You can also serve this cookie as part of a small dessert plate. For another fruit-forward sweet to make when you are feeding more than one person, see these strawberry cream puffs.
Storage and Reheating
This cookie is at its best on the day it is baked, particularly during the first hour when the chocolate is soft and the center is tender. If you need to save it, let it cool completely and keep it in an airtight container at room temperature.
To refresh the texture, warm the cooled cookie briefly until the chocolate softens again. Because this recipe makes only one cookie, it is usually easiest to prepare and bake it when you are ready to enjoy it rather than storing the dough for a long time.
