Easy Cookie in a Mug
Description
This mug cookie recipe mixes melted butter with brown sugar, vanilla, a pinch of salt, and an egg yolk, then adds flour and baking soda before folding in chocolate chips. The batter goes directly into an 8 oz microwave-safe mug greased with the melted butter. Microwaving for 45 to 50 seconds cooks the cookie until it’s puffed and springs back slightly when pressed, indicating doneness. The cookie should remain moist and soft rather than dry. After microwaving, letting it cool briefly in the mug allows it to firm up slightly.
The result is a warm, tender cookie featuring the sweet chewiness of brown sugar and pockets of melted chocolate chips. The mug method creates a convenient dessert for one without baking a whole batch.
This recipe lends itself to mix-in variations including different chocolate chips, nuts, or dried fruit. Care should be taken not to overcook, or the cookie can become dry. Serving is straightforward, eaten directly from the mug once cooled slightly.
Ingredients
- 1 tablespoon butter melted and cooled, unsalted
- 33 g light brown sugar or dark brown sugar
- ¼ teaspoon vanilla extract pure
- 30 g all-purpose flour
- 1/16 teaspoon baking soda a pinch
- 1 egg room temperature, large, yolk
- 2 tablespoons white chocolate chips optional, mix-ins of your preference
- 2 tablespoons semisweet chocolate chips
- 2 tablespoons nuts
- 2 tablespoons dried fruit
- 1/16 teaspoon kosher salt a pinch
Instructions
- Microwave the butter on high in an 8 oz microwave-safe mug until melted, 20 to 35 seconds. Tilt the mug so that the butter greases the sides. Add the brown sugar, vanilla extract, salt, and egg yolk and mix with a fork until combined.
- Add the flour and baking soda, mix until just combined, fold in two-thirds of the chocolate chips, and then sprinkle the remaining chips on the top.
- Microwave on high until the cookie is puffed and springs back when gently pressed for about 45 to 50 seconds, do not overcook, or the chocolate chip cookie will be dry! Let it cool for a few minutes before eating after removing it from the microwave.
Notes
- Use an 8 oz microwave-safe mug and grease it with melted butter to prevent sticking.
- Do not overcook; cook until the cookie puffs and springs back gently to keep it moist.
- Let the cookie cool in the mug for a few minutes after microwaving before eating.
- Feel free to customize by adding your preferred mix-ins like nuts or dried fruit.
- This cookie is best eaten fresh and is not suitable for storage or reheating.
