Ingredients for Your Single Chocolate Chip Cookie
Precise measurements matter when you are scaling down a recipe. I use a small kitchen scale for the most accurate results, but I have included tablespoon measurements too.
- 2 tablespoons (28g) unsalted butter – melted and slightly cooled
- 1 tablespoon (12g) granulated sugar – for crisp edges
- 1.5 tablespoons (20g) light brown sugar – packed, for chewiness and depth
- 1/4 teaspoon vanilla extract – pure vanilla, not imitation
- 1 egg yolk – just the yolk, not the whole egg (this is crucial)
- 1/4 cup (30g) all-purpose flour – spooned and leveled, not packed
- 1/8 teaspoon baking soda – about a pinch, measured properly
- 1/8 teaspoon salt – enhances all the flavors
- 2 tablespoons chocolate chips – semi-sweet or dark, your choice
The egg yolk is the secret here. Using a whole egg would make the cookie cakey and dry. Just the yolk gives you that rich, fudgy center that makes bakery cookies so addictive.
How to Make a Single Chocolate Chip Cookie
Follow these steps exactly for the best results. This recipe makes one large bakery-style cookie or two smaller cookies if you prefer to share.
Step 1: Melt the Butter
Melt your butter in a small microwave-safe bowl for about 20-30 seconds until fully liquid. Let it cool for 2-3 minutes until it is warm but not hot. If the butter is too hot, it will cook the egg yolk when you add it.
Step 2: Mix Sugars and Butter
Add both the granulated sugar and brown sugar to the melted butter. Stir vigorously with a fork or small whisk for about 30 seconds until well combined. The mixture should look like thin caramel and smell amazing already.
Step 3: Add Wet Ingredients
Stir in the vanilla extract first. Then add just the egg yolk, discarding the white or saving it for another use. Mix until the yolk is fully incorporated and the mixture looks smooth and glossy.
Step 4: Add Dry Ingredients
Sprinkle the flour, baking soda, and salt over the wet mixture. Use your fork to gently fold everything together until just combined. Do not overmix. You should still see a few streaks of flour when you are almost done.
Step 5: Fold in Chocolate Chips
Add your chocolate chips and give the dough a final 2-3 folds to distribute them evenly. The dough should be soft, slightly sticky, and hold together when you press it.
Step 6: Shape the Cookie
Scoop the dough onto a small parchment-lined baking sheet or oven-safe plate. For one big cookie, form it into a ball about 2 inches wide and slightly flatten the top. For two cookies, divide the dough in half and shape each portion.
Step 7: Bake at the Right Temperature
Preheat your oven to 350F (175C). Bake the cookie for 10-12 minutes until the edges turn golden brown and the center still looks slightly underdone. The cookie will continue cooking as it cools.
Step 8: Cool and Enjoy
Let the cookie rest on the baking sheet for 5 minutes. This is the hardest part, but it matters. The center needs time to set up. Then transfer to a plate and enjoy warm for maximum gooeyness.
2026 Tips for the Best Single Chocolate Chip Cookie
After making this recipe dozens of times, I have learned a few tricks that make the difference between a good cookie and a great one.
Use Melted Butter, Not Softened
Melted butter creates that dense, fudgy texture you want in a single serve cookie. Softened butter creams into the sugar and adds air, which works for full batches but makes single cookies too cakey.
Measure Flour Correctly
Too much flour and your cookie will be dry and crumbly. Spoon the flour into your measuring cup, then level it off with a knife. Never scoop directly from the bag, which packs the flour down.
Underbake Slightly
Pull the cookie when the edges are golden but the center still looks a bit shiny and soft. It will firm up as it cools. Overbaking is the main reason single cookies turn out dry.
Press Extra Chocolate on Top
Before baking, press 3-4 extra chocolate chips into the top of the dough ball. This gives you those beautiful melty pools of chocolate on the surface that make the cookie look bakery-worthy.
Single Chocolate Chip Cookie Variations
Once you master the base recipe, try these adaptations for different dietary needs and cooking methods.
Eggless Single Chocolate Chip Cookie
Replace the egg yolk with 1 tablespoon of milk or unsweetened applesauce. The milk gives you a slightly cakier texture, while applesauce adds moisture and a subtle sweetness. You can also use 1/2 tablespoon of vegetable oil mixed with 1/2 tablespoon water.
Microwave Single Chocolate Chip Cookie
No oven? No problem. Prepare the dough as written, then place it on a microwave-safe plate. Microwave on high for 40-50 seconds. The cookie will look puffy and slightly wet in the center. Let it rest for 2 minutes before eating. It will be softer and more cake-like than the baked version, but still delicious.
Air Fryer Single Chocolate Chip Cookie
Preheat your air fryer to 320F. Shape the dough and place it on a small piece of parchment paper that fits in your air fryer basket. Cook for 6-8 minutes until the edges are set and golden. The air fryer gives you slightly crispier edges than the oven.
Gluten-Free Version
Swap the all-purpose flour for a 1:1 gluten-free baking blend. I have had success with Bob’s Red Mill and King Arthur blends. The texture is slightly more delicate, so let it cool completely before moving.
Storage and Make-Ahead Tips
Storing Baked Cookies
If you somehow do not eat the whole cookie immediately, store it in an airtight container at room temperature for up to 3 days. Warm it in the microwave for 10 seconds before eating to restore that fresh-baked texture.
Freezing Cookie Dough
This is my favorite make-ahead trick. Make the dough, shape it into a ball, and place it on a small plate in the freezer for 30 minutes until firm. Then transfer to a freezer bag and store for up to 3 months.
When the craving hits, bake the frozen dough straight from the freezer. Just add 2-3 extra minutes to the baking time. You will always have cookie dough ready for emergencies.
Frequently Asked Questions
What is the best single serve chocolate chip cookie recipe?
The best single serve chocolate chip cookie recipe combines melted butter with brown and white sugars, uses just an egg yolk for richness, and bakes at 350F for 10-12 minutes. The key is precise measurements and slightly underbaking for a chewy, gooey center.
How do you make a single chocolate chip cookie without egg?
Replace the egg yolk with 1 tablespoon of milk, applesauce, or a mix of 1/2 tablespoon oil and 1/2 tablespoon water. The milk creates a cakier texture while oil gives you a more traditional cookie consistency.
Can you make a single chocolate chip cookie in the microwave?
Yes. Prepare the dough normally and microwave on a safe plate for 40-50 seconds. Let it rest 2 minutes before eating. The texture will be softer and more cake-like than oven-baked, but still delicious.
What ingredients are needed for one cookie?
You need: 2 tablespoons melted butter, 1 tablespoon granulated sugar, 1.5 tablespoons brown sugar, 1/4 teaspoon vanilla, 1 egg yolk, 1/4 cup flour, 1/8 teaspoon baking soda, 1/8 teaspoon salt, and 2 tablespoons chocolate chips.
How long does a single serve cookie take to bake?
A single serve cookie bakes at 350F for 10-12 minutes until the edges are golden and the center looks slightly underdone. Let it cool for 5 minutes before eating so the center can set properly.
Why did my single cookie spread too much?
Your butter was likely too hot when mixed, or you may have used too much sugar. Let melted butter cool for 2-3 minutes before mixing. Also ensure you are measuring flour correctly by spooning and leveling, not scooping.
