This Chocolate Chip Cookie in a Mug is a warm, gooey, single-serve cookie you can make in about a minute in the microwave—soft, chewy, and loaded with melty chips.

Total Time: PT5M
Yield: 1 serving

Ingredients

Scale

1 tablespoon unsalted butter

1 tablespoon granulated sugar

1 tablespoon packed brown sugar

1/4 teaspoon vanilla extract

Pinch of fine sea salt

1 large egg yolk (room temp)

3 tablespoons all-purpose flour

1/8 teaspoon baking powder (optional, for softness)

2 tablespoons semisweet chocolate chips

Flaky sea salt, for topping (optional)

Cook Mode Prevent your screen from going dark

Instructions

1. 1. Place the butter in a 12-ounce microwave-safe mug and microwave 15–25 seconds until just melted; swirl to coat the mug walls.

2. 2. Whisk in granulated sugar, brown sugar, vanilla, and salt with a fork until glossy.

3. 3. Add the egg yolk and whisk vigorously until fully emulsified, about 10–15 seconds (no streaks left).

4. 4. Stir in flour and baking powder (if using) until just combined; do not overmix.

5. 5. Fold in chocolate chips, reserving a few for the top; level the surface and add remaining chips.

6. 6. Microwave on HIGH for 40–60 seconds (700–1000W). The top should look set but glossy at the center; add 5–10 seconds only if needed.

7. 7. Cool 1–2 minutes to finish setting. Top with flaky sea salt and enjoy warm straight from the mug.

Notes

Use only the yolk for the best soft, chewy texture. Start with 40 seconds; add time in 5–10 second bursts. For deeper flavor, brown the butter first and let it cool slightly before mixing.

The microwave magic behind mug cookies

When you crave a fresh-from-the-oven cookie but only have five minutes, Chocolate Chip Cookie in a Mug delivers the soft, gooey center and buttery edges you love—fast.

The small batch size keeps the crumb delicate, and the mug acts like a mini baking chamber, concentrating heat. With just a fork and a few pantry staples, you get a single-serve cookie that’s warm, melty, and wildly satisfying. For late-night dessert emergencies, a Chocolate Chip Cookie in a Mug is the hero of your kitchen.

Short-form video made this microwave cookie a star, and for good reason: portion control, zero preheat, and that nostalgic bakery aroma in minutes. A Chocolate Chip Cookie in a Mug fits perfectly into busy routines—study breaks, movie marathons, or post-dinner cravings. It’s also endlessly customizable: swap in brown butter for deeper flavor, use mini chips for more even melt, or add a pinch of espresso powder for bolder notes.

How to Make Chocolate Chip Cookie in a Mug (Step by Step)

Exact measurements for that chewy, gooey bite

To nail the texture of a Chocolate Chip Cookie in a Mug, keep measurements precise. Use 1 tablespoon each of granulated and brown sugar for balanced sweetness and moisture. One egg yolk provides richness without the rubberiness a whole egg can create in small-format baking. Three tablespoons of flour is the sweet spot for a tender, scoopable crumb. A pinch of salt sharpens flavors, and 2 tablespoons of chocolate chips create melty pockets in every spoonful. In 40–60 seconds, your Chocolate Chip Cookie in a Mug transforms from a quick batter into a soft, warm dessert—with no bowls to wash and no mixer to clean.

Pro tips to prevent dry or rubbery results

Use a 12-ounce mug: It gives your Chocolate Chip Cookie in a Mug room to rise without overflowing.
Do not overmix: Gentle stirring keeps the crumb tender and prevents gluten toughness.
Know your microwave: Start at 40 seconds; add 5–10 seconds until the center looks just set.
Rest before eating: A 1–2 minute rest lets your Chocolate Chip Cookie in a Mug finish cooking through carryover heat.
Optional baking powder: A tiny 1/8 teaspoon adds lift if you like a softer, cake-ier cookie.
