Ingredients You’ll Need

What makes this Chocolate Chip Cookie In A Mug extra special is just how accessible the ingredients are. Each one is a powerhouse, working together to create classic cookie flavor and the most crave-worthy soft texture—all in one adorable mug.

Unsalted butter: Brings rich flavor and moisture; melting it first helps everything blend easily.
Granulated sugar: Adds sweetness and helps create that perfect, slightly crisp top texture.
Brown sugar: Brings a touch of caramel-like depth and keeps the cookie deliciously soft.
Vanilla extract: Just a splash enhances the overall cookie flavor and aroma.
Pinch of salt: Balances the sweetness and sharpens every flavor note.
Egg yolk: Gives the cookie structure and a wonderfully tender crumb.
All-purpose flour: Forms the body of the cookie, giving it that classic, chewy structure.
Chocolate chips: The magical bursts of molten chocolate that make every bite pure bliss.

How to Make Chocolate Chip Cookie In A Mug

Step 1: Melt the Butter

Start by placing the tablespoon of unsalted butter in your favorite microwave-safe mug. Pop it in the microwave for about 20 to 30 seconds, just until it’s fully melted. This step ensures all the other ingredients will blend together smoothly and you won’t end up with any dry pockets of flour later.

Step 2: Stir in Sugars, Vanilla, and Salt

Once the butter is liquid gold, add both the granulated and brown sugars, along with the vanilla extract and a pinch of salt. Stir thoroughly until the mixture is well combined and glossy. This is where your cookie’s signature sweet, toasty flavor starts coming together.

Step 3: Add the Egg Yolk

Next, mix in the egg yolk (just the yolk—save the white for another use). The yolk is key to creating a rich, tender texture, and lets the cookie bind perfectly without becoming dry or tough.

Step 4: Mix in the Flour

Add three tablespoons of all-purpose flour right into the mug. Gently stir until the flour is fully incorporated and you’re left with a soft dough. The mixture should look like classic cookie dough, but a little looser—that’s exactly what you want.

Step 5: Fold in Chocolate Chips

Now for the best part! Fold in the chocolate chips so they’re evenly scattered throughout the dough. Their melty magic is what takes this from just a mug cookie to Chocolate Chip Cookie In A Mug perfection.

Step 6: Microwave to Cookie Glory

Microwave your mug cookie on high for 40 to 60 seconds. Keep a close eye: It should be just set on top but still a little soft in the center. Remember, it will continue to cook slightly as it cools, so it’s better to underdo than overdo—no one likes a dry cookie!

Step 7: Cool Briefly, Then Dig In

Let your Chocolate Chip Cookie In A Mug rest for a minute or two after microwaving. This lets the crumb finish setting and keeps you from burning your tongue. Grab a spoon—and maybe a scoop of vanilla ice cream if you’re feeling extra. Dessert, made in minutes and all for you!

How to Serve Chocolate Chip Cookie In A Mug

Garnishes

Add an extra sprinkle of chocolate chips right on top as soon as it’s out of the microwave. They’ll melt into little puddles of chocolate. Or, top with a pinch of flaky sea salt for that irresistible sweet-and-salty combination. A scoop of ice cream or a drizzle of chocolate or caramel sauce never hurts either!

Side Dishes

This mug cookie is pure comfort and deserves a little pairing love. It goes perfectly with a cold glass of milk, a hot mug of coffee, or even a foamy cappuccino. For a dessert platter vibe, serve it alongside some fresh berries or sliced banana for a touch of brightness.

Creative Ways to Present

For a fun twist, serve your Chocolate Chip Cookie In A Mug in a colorful or quirky mug—make dessert feel extra special. If you’re making a few for a family movie night, line up different mugs, each garnished differently, and let everyone customize their own. You could even serve with cute cocktail spoons for that extra cafe-at-home feel!

Make Ahead and Storage

Storing Leftovers

If you somehow have leftovers (it’s rare!), cover the mug with plastic wrap or transfer the cookie to an airtight container. It’ll stay tasty at room temperature for up to a day, but fresher is always better since this recipe is all about its gooey, just-baked glory.

Freezing

While this recipe is designed for instant gratification, you can freeze the raw dough. Just mix everything except for the egg yolk, then freeze in a small, lidded container. When ready to indulge, thaw slightly, stir in the yolk, and microwave as usual.

Reheating

To reheat, microwave your leftover mug cookie in 10-second bursts until just warmed through. Don’t overdo it, or it may turn tough. If the cookie seems a little dry, top with a tiny pat of butter or a splash of milk before reheating for extra moisture.

FAQs

Can I double this Chocolate Chip Cookie In A Mug recipe?

Absolutely, but for best results, microwave each mug separately. If you try to cook two at once, they often cook unevenly, so it’s worth the extra minute to do them one at a time.

What’s the secret to a super gooey center?

The trick is to slightly undercook your mug cookie. Aim for 40 seconds first—if it looks a little wet on top, let it rest for a minute, and it will firm up but stay gooey inside.

Can I make this recipe vegan?

Yes! Swap the butter for plant-based margarine, use a non-dairy chocolate chip, and replace the egg yolk with a tablespoon of non-dairy milk or unsweetened applesauce. The texture will shift a little, but the cookie will still be super satisfying.

Why use just an egg yolk instead of a whole egg?

A whole egg would be too much moisture and make the cookie rubbery. Using just the yolk ensures a tender, rich crumb—just like your favorite bakery cookies, but downsized.

Can I add nuts or other mix-ins?

Definitely! Feel free to fold in a spoonful of chopped nuts, dried fruit, coconut flakes, white chocolate, or even toffee bits for a customized Chocolate Chip Cookie In A Mug every time.

Final Thoughts

If you love cookies and crave something sweet in a snap, honestly, you need to give this Chocolate Chip Cookie In A Mug a try. It’s quick, comforting, endlessly customizable, and always hits the spot. Treat yourself—you totally deserve it!
