Ingredients You’ll Need

The beauty of a Cookie in a Mug is how it turns simple, everyday ingredients into something truly magical. Each one plays a crucial role, whether it’s giving that chewy center, buttery flavor, or irresistible chocolatey bite. Let’s break down what you’ll need and why it matters!

• Unsalted butter: Gives the cookie its rich, classic flavor and melt-in-your-mouth texture.
• Light brown sugar: Adds warmth and moisture, bringing out that signature caramel note in every bite.
• Granulated sugar: Enhances sweetness and rounds out the cookie’s classic flavor profile.
• Vanilla extract: Infuses the mug cookie with a heavenly aroma and boosts overall flavor depth.
• Salt: Balances out the sweetness and wakes up all the other flavors.
• Egg yolk: Binds everything together, giving a luscious, tender crumb without making the cookie cakey.
• All-purpose flour: Forms the body of the cookie, ensuring just the right thickness and chew.
• Semisweet chocolate chips: Melty, rich pockets of chocolate make every bite feel like a real treat!

How to Make Cookie in a Mug

Step 1: Melt the Butter

Drop a tablespoon of unsalted butter into your favorite 8-ounce microwave-safe mug. A quick 30 seconds in the microwave is all it takes—the butter should be mostly melted, but it’s fine if a few unmelted bits remain. This step lays the flavor foundation for your Cookie in a Mug, so don’t skip it!

Step 2: Stir in the Sugars, Vanilla, and Salt

Add your light brown sugar, granulated sugar, vanilla extract, and a pinch of salt right into the mug. Use a spoon to mix everything together until fully combined. At this point, your kitchen might already start to smell like a bakery—enjoy it!

Step 3: Add the Egg Yolk

Just the yolk, not the whole egg! Stir it in until everything’s silky-smooth and no streaks remain. The egg yolk keeps your Cookie in a Mug tender and chewy instead of dry or rubbery.

Step 4: Incorporate the Flour and Chocolate Chips

Sprinkle all-purpose flour into the mug, followed by most of your chocolate chips. Gently mix until you have a thick but uniform dough. Save a few chocolate chips to press on top for that bakery-style finish—trust me, it’s worth it!

Step 5: Microwave to Perfection

Pop the mug in the microwave and cook on high for 45 seconds to 1 minute. The cookie will puff up and the top should look set and dry—resist the urge to overbake, because a slightly gooey center is pure Cookie in a Mug magic. Allow it to cool for a couple of minutes before digging in.

How to Serve Cookie in a Mug

Garnishes

Elevate your Cookie in a Mug with a scoop of vanilla ice cream for maximum indulgence. A sprinkle of flaky salt or a drizzle of chocolate sauce can add a gourmet touch and make your mug treat even more irresistible.

Side Dishes

While this dessert shines on its own, you can pair it with a small glass of cold milk or hot coffee for the ultimate comfort combo. If you’re sharing dessert time with a friend, serve alongside some fresh berries for a balancing burst of brightness.

Creative Ways to Present

Surprise someone special by customizing their Cookie in a Mug: swap in white chocolate chips, top with colorful sprinkles, or add a dollop of whipped cream. Gift it in a cute mug with a handwritten tag for an adorable, personalized sweet treat.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (which, honestly, is rare!), simply cover the mug with plastic wrap and keep it in the refrigerator for up to 2 days. The cookie will firm up a bit, but a quick warm-up brings back its softness.

Freezing

To freeze, spoon the uncooked mug cookie dough into a freezer-safe mug or container. When the craving strikes, microwave directly from frozen—just add an extra 10–15 seconds to the cook time. Fresh-baked Cookie in a Mug at your fingertips, any night of the week!

Reheating

For that fresh-from-the-oven warmth, microwave your stored Cookie in a Mug for about 10–15 seconds. Keep a close eye so you don’t overcook it; you want it yummy and tender, not dry.

FAQs

Can I make Cookie in a Mug without eggs?

Absolutely! You can substitute the egg yolk with 1 tablespoon of milk or non-dairy milk. The texture will be slightly different but still delicious and chewy.

What type of mug should I use for this recipe?

A standard 8-ounce, microwave-safe mug works best. Avoid anything with metallic paint or decorations, and make sure there’s enough room for the cookie to rise without overflowing.

Can I use dark chocolate or other add-ins?

Yes! Cookie in a Mug is super versatile. Try dark or milk chocolate chips, peanut butter chips, chopped nuts, or even a swirl of Nutella.

Why did my Cookie in a Mug turn out dry?

This usually means it was microwaved too long or your mug was smaller. Next time, check at 45 seconds, and remember: a slightly gooey center is perfection.

Can I double the recipe?

It’s best to make Cookie in a Mug one at a time for even cooking, but if you’re sharing, divide the batter between two mugs and microwave separately.
