I love making this quick chocolate chip cookie in a mug whenever I want something sweet without baking a whole batch of cookies. It comes together in just a minute, uses simple pantry ingredients, and creates a soft, warm cookie filled with melted chocolate chips. I enjoy how easy it is to prepare and clean up afterward.
Why You’ll Love This Recipe
I love this recipe because it is incredibly fast and satisfying. I can mix everything directly in one mug, which means there are fewer dishes to wash. The texture turns out soft and chewy, and the chocolate chips melt perfectly into the warm cookie. I also like how easy it is to customize with nuts, caramel, or different types of chocolate.

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
1 tablespoon unsalted butter, melted
1 tablespoon granulated sugar
1 tablespoon brown sugar
2 drops vanilla extract
Pinch of salt
1 egg yolk
3 tablespoons all-purpose flour
2 tablespoons chocolate chips

I melt the butter directly in a microwave-safe mug.
I stir in the granulated sugar, brown sugar, vanilla extract, and salt until smooth.
I mix in the egg yolk until fully combined.
I add the flour and stir gently until no dry streaks remain.
I fold in the chocolate chips.
I microwave the mug for about 40 to 60 seconds, depending on the microwave strength.
I let the cookie cool for a minute before enjoying it warm.
Servings and Timing
Servings: 1 mug cookie
Prep Time: 2 minutes
Cook Time: 1 minute
Total Time: About 3 minutes
Variations
I sometimes use white chocolate chips or dark chocolate chunks for a different flavor.
I like adding chopped walnuts or pecans for extra crunch.
I occasionally mix in a spoonful of peanut butter for a richer taste.
I enjoy sprinkling a little cinnamon into the batter during colder months.
I sometimes top the warm cookie with a scoop of vanilla ice cream.
Storage/Reheating
I usually eat this cookie fresh because it tastes best warm right after cooking. If I have leftovers, I cover the mug and keep it at room temperature for up to one day. To reheat, I microwave it for about 10 seconds to soften the texture again.
FAQs
Can I make this recipe without brown sugar?
I can replace the brown sugar with more granulated sugar, although the cookie may lose a little softness and caramel flavor.
Can I use a whole egg instead of an egg yolk?
I prefer using only the yolk because it keeps the texture soft and rich. A whole egg adds too much liquid for a single mug cookie.
Why did my cookie turn rubbery?
I find that overcooking is usually the reason. I microwave the cookie just until the top looks set.
Can I make this recipe gluten-free?
I can use a gluten-free all-purpose flour blend, and the cookie still turns out delicious.
What size mug works best?
I like using a standard microwave-safe mug that holds at least 10 ounces to prevent overflowing.
Conclusion
I enjoy making this 1-minute chocolate chip cookie in a mug whenever I need a quick dessert without much effort. The recipe is simple, warm, comforting, and perfect for satisfying chocolate cravings in just a few minutes. It has become one of my favorite easy treats for busy days or late-night snacks.
