How to Make Cookie in a Mug
Note: The full instructions are provided in the recipe card below.
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 sprinkle the remaining chips on 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.
- All-purpose flour: You could use almond or oat flour for a gluten-free option or whole wheat flour for a healthier option.
- Brown sugar: You could use granulated sugar instead or a sugar substitute like stevia or erythritol for a lower-calorie option.
- Unsalted butter: You could use salted butter instead, but you may want to reduce the amount of additional salt called for in the recipe. Alternatively, you could use coconut or vegetable oil as a dairy-free option.
- Egg yolk: You could use a flax or chia egg (1 tablespoon ground flaxseed or chia seeds mixed with 3 tablespoons water) for a vegan option, or omit the egg yolk altogether for a denser, more fudgy texture.
- Mix-ins: Feel free to use any mix-ins you like! Some ideas include raisins, dried cranberries, chopped nuts, peanut butter chips, butterscotch chips, or shredded coconut.
- Baking soda: You could try using baking powder instead, but you may need to adjust the amount called for in the recipe.
- Double Chocolate Chip: Add 2 tablespoons of cocoa powder to the dry ingredients, and replace the mix-ins with 2 tablespoons of chocolate chips.
- Peanut Butter: Replace the butter with 1 tablespoon of peanut butter, and add 2 tablespoons of chopped peanuts to the mix-ins.
- Oatmeal Raisin: Replace 1 tablespoon of the flour with quick oats, and replace the mix-ins with 2 tablespoons of raisins and a pinch of cinnamon.
- White Chocolate Macadamia Nut: Replace the mix-ins with 2 tablespoons of white chocolate chips and 2 tablespoons of chopped macadamia nuts.
- Salted Caramel: Replace the brown sugar with 2 tablespoons of caramel sauce, and add a pinch of sea salt to the dry ingredients.
- Funfetti: Replace 1 tablespoon of the flour with rainbow sprinkles, and replace the mix-ins with 2 tablespoons of white chocolate chips.
How to Serve
The "Cookie in a Mug" recipe is a quick and easy dessert that can be enjoyed any time of day. Once the cookie is baking in the microwave, it can be served hot and gooey directly from the mug. Add a scoop of vanilla ice cream or a dollop of whipped cream on top for a more indulgent treat. Drizzle chocolate or caramel sauce over the cookie to make it extra special, or sprinkle some additional mix-ins. Just be careful not to burn your tongue on the hot cookie!
How to Store & Re-Heat
To store: If you have any leftover "Cookie in a Mug," you can store it in an airtight container at room temperature for up to 2 days. Alternatively, you can wrap the cookie in plastic wrap and freeze it for up to 1 month.
To reheat: Place Cookie in a Mug in a microwave for 10-15 seconds until warm and gooey. Warm it up in a preheated oven at 350°F for 5-10 minutes. Just be careful not to overheat it, or it may become dry and tough. Enjoy your reheated cookie alone or with a scoop of ice cream for an extra decadent treat.
The Cookie in a Mug recipe is meant to be made and consumed immediately, but you can still prepare some components ahead of time to make the process faster and easier. For example, you can measure the dry ingredients and mix-ins ahead of time and store them in separate containers until ready to use. You can also melt the butter and let it cool to room temperature before using it.
Another option is to mix the dry ingredients in a larger batch and store the mixture in an airtight container until you're ready to make a mug cookie. This way, you can easily measure the desired amount of the mixture and add the wet ingredients as needed. While the texture and flavor of a "Cookie in a Mug" is best when it's freshly made, preparing some of the components ahead of time can still save you some time and effort in the kitchen.
How to Freeze
If you'd like to freeze your "Cookie in a Mug" dough for later use, it's essential to prepare it properly to avoid freezer burn or other issues. The easiest way to freeze the dough is to shape it into a ball and wrap it tightly in plastic or aluminum foil. Make sure to squeeze out any excess air and seal the package securely. Then, label the wrapped dough in a freezer-safe container or resealable plastic bag with the date and contents.
When you're ready to bake the cookie, remove the dough from the freezer and let it thaw in the refrigerator or at room temperature for a few hours. Once completely thawed, you can shape it into a mug and microwave it as usual. Remember that the texture and flavor may differ from a freshly made cookie, but it can still be a convenient and tasty treat.
Tips for Making Cookie in a Mug
- Use room temperature ingredients: Make sure your egg yolk and butter are at room temperature before using them in the recipe. This will help them blend more efficiently and create a smoother texture.
- Mix thoroughly: Be sure to mix the dry ingredients thoroughly before adding the wet ingredients. This will help ensure that the cookie bakes evenly and has no lumps or pockets of flour.
- Don't over-mix: Once you add the wet ingredients to the dry ingredients, be careful not to over-mix the dough. Over-mixing can make the cookie tough and dense.
- Use the right mug: Use a microwave-safe mug at least 12 ounces in size. The cookie will rise as it bakes, so you must ensure enough room to expand without overflowing.
- Adjust the baking time: Depending on the power of your microwave, you may need to adjust the baking time slightly. Start with the recommended time, then add additional time in 5-second increments if necessary. The cookie should be puffed up and set around the edges but still slightly soft and gooey in the center.
- Add toppings or mix-ins: Feel free to customize your mug cookie with your favorite toppings or mix-ins. Just be sure to add only a few; they may weigh down the cookie and prevent it from rising properly.

The cookie in my mug didn't rise properly in the microwave. What might have gone wrong?
If your cookie didn't rise properly, it could be due to insufficient baking soda or overmixing the dough. Ensure you measure the baking soda accurately and mix the dough until combined to avoid overworking it.
The cookie in my mug has a strange taste. How can I enhance its flavor?
To enhance the flavor of your cookie in a mug, consider adding more vanilla extract or trying different mix-ins like flavored chocolate chips, nuts, or spices such as cinnamon. Adjusting the sweetness level with brown sugar can also impact the flavor.
My cookie in a mug didn't cook evenly. The edges are overcooked, and the center is undercooked. How can I achieve a more uniform texture?
Even cooking can be challenging in a microwave, but you can try rotating the mug halfway through the cooking time to help distribute the heat more evenly. Also, ensure the batter is evenly distributed in the mug before microwaving.
Can I make this cookie in a mug with gluten-free flour?
You can adapt this recipe to use gluten-free flour if needed. Simply substitute a gluten-free all-purpose flour blend for the regular all-purpose flour. Be aware that the texture and flavor may vary slightly with gluten-free flour.
Can I use other mix-ins besides chocolate chips?
Certainly! You can customize your cookie in a mug with various mix-ins like nuts, dried fruit, different types of chocolate chips, or even sprinkles for a fun twist.
My cookie in a mug overflowed while cooking. How can I prevent this from happening again?
To prevent overflow, ensure that your mug has enough room for the cookie to expand as it cooks. Don't fill the mug more than halfway with the cookie dough to leave ample space for rising.
Can I double or triple the recipe to make multiple servings at once?
You can double or triple the recipe to make multiple servings in separate mugs. Just be sure to adjust the cooking time accordingly, as cooking times may vary when using multiple mugs in the microwave.
