Ingredients You’ll Need

All it takes are a handful of pantry staples to whip up a Cookie in a Mug that rivals anything from your favorite bakery. Each ingredient plays a vital role, from richness of butter to a hint of vanilla, ensuring every bite tastes as indulgent as the ones you grew up loving.

• Unsalted butter (1 tbsp, melted): This adds rich flavor and keeps your cookie soft and tender; you can also use salted butter and skip a pinch of added salt.
• Granulated sugar (1 tbsp): Provides classic sweetness and contributes to that chewy cookie texture.
• Brown sugar, packed (1 tbsp): Adds depth and a touch of caramel flavor you just can’t get with white sugar alone.
• Vanilla extract (0.25 tsp): Just a splash really boosts the classic cookie flavor.
• Milk (1 tbsp): Keeps the cookie moist and helps everything blend together easily.
• All-purpose flour, sifted (3 tbsp): Delivers the perfect texture; sifting makes it extra light and helps prevent lumps.
• Baking powder (0.25 tsp): Gives your cookie a gentle lift, creating a soft bite instead of a dense one.
• Chocolate chips (1 tbsp): Because what’s a cookie in a mug without those gooey, melt-in-your-mouth chocolate pockets?

How to Make Cookie in a Mug

Step 1: Melt Butter

Begin by grabbing your favorite microwave-safe mug—the one that feels just right in your hands. Add the butter and microwave it for about 15 seconds, just until melted. Swirl the mug gently to coat the sides, which will help prevent sticking later.

Step 2: Mix Wet Ingredients

Into your freshly melted butter, add the granulated sugar, brown sugar, vanilla extract, and milk. Take a fork and stir well, so the mixture is cohesive and silky-smooth. This is the moment when the sweet, cozy aroma starts wafting up—try not to eat it with a spoon just yet!

Step 3: Add Dry Ingredients

Now, sprinkle in the sifted flour and baking powder. Stir gently, just until everything is combined and no dry streaks remain. Avoid overmixing—the key is to keep the cookie tender.

Step 4: Fold in Chocolate Chips

Fold in the chocolate chips, making sure they’re evenly distributed. This ensures that every bite of your Cookie in a Mug comes with a gooey chocolate surprise.

Step 5: Microwave

Pop the mug into the microwave and heat it on high for 45 to 60 seconds. The cookie should look set on top but feel a little soft in the middle—just like a perfect underbaked cookie! Every microwave is a bit different, so start checking at 45 seconds.

Step 6: Cool and Enjoy

Give your Cookie in a Mug a minute to cool and firm up—resist the urge to dig in immediately, as it’s piping hot! Grab a spoon and enjoy the melty, dreamy warmth straight from the mug.

How to Serve Cookie in a Mug

Garnishes

For an extra flourish, sprinkle a pinch of sea salt on top or add a drizzle of chocolate or caramel sauce. A scoop of ice cream is pure luxury with a warm Cookie in a Mug, making it feel like a restaurant-worthy treat.

Side Dishes

Pair your Cookie in a Mug with a glass of cold milk, a frothy cappuccino, or a mug of herbal tea. If you’re feeling extra fancy, a fruit salad or a small handful of berries on the side complements the sweetness beautifully.

Creative Ways to Present

Serve your Cookie in a Mug with a tiny spoon for extra cuteness, or garnish with whipped cream and sprinkles for special occasions. You can also make a DIY dessert bar—set out mugs and toppings and let everyone create their own personalized treat!

Make Ahead and Storage

Storing Leftovers

If you happen to have leftovers (though that’s rare!), simply cover the mug with plastic wrap or transfer the cookie to an airtight container. It will stay soft and delicious at room temperature for up to two days.

Freezing

While Cookie in a Mug is best enjoyed fresh, you can prep and freeze portions of the cookie dough in small containers or wrap the baked cookie in plastic and store in the freezer for up to a month. When the craving strikes, just thaw and enjoy!

Reheating

To recapture that just-baked warmth, microwave your stored or frozen Cookie in a Mug for 10 to 15 seconds until heated through. The chocolate chips will melt again, making each bite just as irresistible as when you first made it.

FAQs

Can I use plant-based butter or non-dairy milk?

Absolutely! This Cookie in a Mug is super versatile—swap in vegan butter and almond, oat, or soy milk for a dairy-free version that tastes just as luscious as the original.

What size mug works best for this recipe?

A standard 10- to 12-ounce mug works perfectly, giving the cookie plenty of room to rise without any overflow. Just avoid anything too small or shallow.

Can I use self-rising flour instead of all-purpose flour and baking powder?

Yes, you can substitute self-rising flour for the flour and baking powder—just use 3 tablespoons and leave out the extra leavening. The result works wonderfully in a pinch.

Can I add nuts or other mix-ins?

Go for it! Chopped nuts, white chocolate chips, toffee bits, or even a sprinkle of toasted coconut all make fantastic additions to your Cookie in a Mug. Get creative and make it your own.

Why is my mug cookie dry or rubbery?

Microwaving for too long is the biggest culprit—45 to 60 seconds is usually perfect. If your microwave runs hot, check at 40 to 45 seconds to keep your cookie wonderfully soft and not overdone.
