If you’ve found yourself longing for a chocolatey snack but don’t want to deal with the hassle of firing up the oven and baking a full batch of sweets, then this recipe is just the thing for you.

Say “not today” to a stack of dirty mixing bowls and pans and get ready to enjoy the delicious simplicity of a brownie in a mug!

What are the best parts of a brownie in a mug?

First: As we’ve already established, one of the best things about baking a brownie in a mug is the streamlined process and easy cleanup.

If you’re craving something sweet and don’t want to wait or deal with any involved prep work, then you’ll be thrilled to learn that you can complete this recipe in well under ten minutes–probably far less!

Another perk of the “mug method” of baking individual brownies is versatility.

If you’ve got a friend over for an afternoon coffee and want to enjoy a snack together but discover that your tastes clash, then mug brownies are a perfect solution.

If your buddy loves peppermint while you’re more of a caramel person, then you can each enjoy a brownie that’s made just right for you.

A brownie in a mug can also be an ideal treat for someone who’s trying to manage their calorie intake.

Let’s be honest: It can be pretty hard to find a brownie that’s as low-calorie as it is delicious.

But making yourself a single-serving brownie in a mug will at least make it a whole lot easier to keep yourself from going back for seconds.

Before anything else, show me that ingredients list!

Here are all the ingredients you’ll need for your microwave brownie in a mug:

3 tablespoons granulated sugar
3 tablespoons all purpose flour
1 ½ tablespoons unsweetened cocoa powder
Pinch of salt
2-3 tablespoons chocolate chips (use extra for topping if desired)
1 ½ tablespoons vegetable oil or melted butter
3 tablespoons milk
¼ teaspoon vanilla extract

Let’s get started:

First off, find yourself a good, microwave-safe 12-16 oz. mug to make your brownie in.

Begin your process by mixing your dry ingredients together in the mug: Combine your sugar, flour, cocoa powder, and the pinch of salt with a fork to eliminate as many clumps as possible.

Your end result should be smooth and look something like a hot cocoa mix. If you have a mini whisk that fits into the mug then that will work well for mixing, too.

Stir your chocolate chips into the dry ingredient mixture so that each one is thoroughly coated with dry powder.

Next, add in the vegetable oil or melted butter. Many people find that the flavor of the butter is well worth dirtying the additional dish that it takes to melt it!

However, if you’d rather avoid as much cleanup as possible, then vegetable or grapeseed oil can be added right in. Coconut oil, which is often at least partially liquid at room temperature, also works and tastes great.

Now it’s time to add in your milk and vanilla extract. If you or a friend prefer to keep things dairy-free, then almond, oat, and coconut milk are reliable alternatives that each add their own great flavor.

Make sure you try to get your batter as smooth as possible without over-mixing.

When you’re done mixing, take a spoon or a small spatula and do your best to scrape all the batter down the sides and into the mug. This will help prevent the thin smudges of batter from overcooking or burning in the microwave.

If you set aside any chocolate chips to top your tasty creation with, now is their time to shine! Add them to the top of your brownie batter and press them down into the batter just a bit so that they’ll melt in nicely without overheating.

Now you’re ready to bake! Pop your mug brownie into the microwave and let it run on high for around 90 seconds. Make sure you watch the brownie so that you can monitor its doneness–you don’t want to overcook it, and the cooking time can vary according to your individual microwave and mug.

Be careful while removing your piping-hot dessert from the microwave. These tasty mug brownies are best when served immediately–and topped with a small scoop of ice cream!

Any extra important tips or things to watch out for?

It can’t be stressed enough: Keep a close eye on your mug brownie while it’s cooking since each microwave is different. Cooking times will likely need a bit of adjustment depending on the strength and settings of your particular appliance.

The perfect timer setting on one microwave might be too much on another, resulting in an overcooked dessert!

Make sure you catch your brownie at the right level of doneness, even if that means stopping the microwave early. You want to see your brownie “puff up” a bit in the mug so that it appears cakelike and fluffy.

This is especially important while you’re first getting a feel for the right cook time in your particular kitchen. If you see your mug brownie starting to harden or deflate significantly, stop the microwave right away–you’re well on the way to overcooking it.

One of the ways you can make it easier to monitor your brownie is to nail down your ideal mug size.

Bigger isn’t always better: In this case, a 12 oz or 14 oz mug may make it easier for you to see over the rim and keep an eye on things during the cooking process.

What are some other things I can do to really set off my mug brownie?

When it comes to making your brownie a truly perfect dessert in a mug, the sky’s the limit! If it fits in the mug, you can top your brownie with it.

Strawberries and/or blueberries are delicious with this recipe, as are any types of nuts you might enjoy.

Caramel sauce, crumbled-up cookies, peppermint bark, and whipped cream are all delicious as well!


The next time you’re hankering for a sweet, easy snack or looking for the perfect treat while entertaining a guest, this brownie in a mug is an excellent solution! Just make sure you blend your ingredients in the right order to avoid over-mixing and keep your dessert light and fluffy.

Additionally, make sure you keep an eye on your mug brownie while it cooks so that you can stop the microwave and retrieve it at just the right time to enjoy peak doneness. Don’t be afraid to get creative with toppings like fruit, nuts, or syrups–and don’t forget the ice cream!
