HOW TO MAKE A 15-MINUTE AIR FRYER MUG COOKIE

Ingredients

• 1 tablespoon unsalted butter, melted
• 1 tablespoon granulated sugar
• 1 tablespoon light brown sugar, packed
• 1 large egg yolk (see tip below!)
• ¼ teaspoon vanilla extract
• 3 tablespoons all-purpose flour
• ⅛ teaspoon baking powder
• Pinch of salt
• 2 tablespoons chocolate chips, plus more for topping

Directions

First, in a standard-sized, microwave-safe mug, melt your butter in the microwave for about 15-20 seconds.

Next, to the melted butter, add the granulated sugar, brown sugar, egg yolk, and vanilla extract. Use a small fork or spoon to mix vigorously until it becomes a smooth, glossy paste.

Now, sprinkle the flour, baking powder, and salt over the wet ingredients. Stir until just combined and no dry streaks remain. Be careful not to overmix.

Gently fold in those glorious chocolate chips, saving a few to press on top for a bakery-style look.

Finally, place the mug in the basket of your air fryer. Air fry at 350°F (175°C) for 8-10 minutes. Start checking at 8 minutes the top should be set and look cookie-like, but the center will still be deliciously soft.

Carefully remove the mug (it will be hot!). Let it cool for just 2-3 minutes before digging in with a spoon. The wait is the hardest part!

NUTRITION AND HEALTH CONSIDERATIONS 15-MINUTE AIR FRYER MUG COOKIE

A Conscious Indulgence

This 15-Minute Air Fryer Mug Cookie is a dessert, through and through, but its single-serving nature is its own form of portion control. You’re enjoying a freshly baked treat made with real ingredients, which is always a better choice than a highly processed packaged snack. You control the sugar and the quality of chocolate.

Simple Swaps for Dietary Needs

You can easily adapt this tiny treat! For a gluten-free version, use a 1:1 gluten-free flour blend. To make it dairy-free, use vegan butter and dairy-free chocolate chips. The egg yolk is crucial for texture, but for an egg-free version, you could try substituting half a tablespoon of applesauce.

HOW TO SERVE A 15-MINUTE AIR FRYER MUG COOKIE

The Ultimate Solo Dessert Experience

Serve it right in the mug it was baked in, with a spoon and a smile. That’s it! The beauty is in its simplicity. The warmth of the mug, the melty chocolate, the cozy aroma it’s a full sensory experience.

Level It Up Like a Pro

If you’re feeling fancy, take it over the top. Slide the warm cookie out onto a plate and add a scoop of vanilla ice cream for the world’s fastest cookie à la mode. A drizzle of salted caramel or a flake of sea salt on top is also a game-changer.

HOW TO STORE (BUT YOU WON’T NEED TO)

The “Make It and Eat It” Reality

Let’s be honest: storage isn’t really a factor here. This is a made-to-order, immediate-consumption delight. The cookie is best enjoyed within minutes of coming out of the air fryer while the chocolate is still wonderfully gooey.

Mix Dry Ingredients Ahead

If you want to make the process even faster for future cravings, you can pre-mix the dry ingredients (flour, baking powder, salt) in a small jar. When the mood strikes, just add your pre-measured dry mix to the wet ingredients in the mug. Boom instant cookie.

TIPS TO MAKE THE PERFECT AIR FRYER MUG COOKIE

Tips and Notes: Your Kitchen Companion

• The Egg Yolk is Key: Using just the yolk (not the whole egg) gives this cookie its rich, soft, and fudgy texture. Save the white for an omelet!
• Don’t Overcook: The cookie will continue to cook in the hot mug after it comes out. Pull it when the top looks set but the center is still slightly soft. It should look a little underdone for the perfect final texture.
• Use the Right Mug: Choose a standard ceramic mug that is microwave-safe and fits comfortably in your air fryer basket without touching the top or sides.

Details

The type of chocolate chip matters here. I recommend standard semi-sweet morsels, but a chopped-up chocolate bar will give you amazing melty pockets. Mini chocolate chips distribute flavor in every bite.

Variation

Feel free to get creative! Swap out chocolate chips for white chocolate and dried cranberries. Add a tablespoon of peanut butter to the wet mix. Stir in a pinch of cinnamon or instant espresso powder for a flavor twist.

Notes

All air fryers have slight temperature variations. Your first cookie is a test run for your specific appliance. Note the perfect time for your preferred doneness. If your mug is very deep, it might need an extra minute or two.

15-MINUTE AIR FRYER MUG COOKIE FAQs

Can I make this in the microwave instead?

You can, but the texture is very different. Microwaving makes it more cake-like and steamy. The air fryer gives you that authentic, slightly crispy-edged, baked cookie texture. The air fryer method is superior.

What can I do with the leftover egg white?

You can save it for a healthy breakfast scramble, whip it into a cocktail (like a whiskey sour), or make a small portion of royal icing for another baking project. Don’t let it go to waste!

My cookie came out dry. What happened?

This almost always means it was overcooked. Next time, reduce the time by 1-2 minutes. Also, ensure you’re using a tablespoon measure for the butter and sugars; too much flour or not enough fat will also cause dryness.
