The best Fudgy 1 minute Brownie Mug Cake
When a chocolate craving hits at 9 pm, the last thing you want is to preheat an oven, soften butter on the counter, or pull out a stand mixer. You want fudgy, warm, chocolate goodness, and you want it now. This Fudgy 1 minute Brownie Mug Cake is built for exactly that moment.
It is a single serve brownie made in one mug, cooked in the microwave, and loaded with real chocolate. Mixing the ingredients takes about 30 seconds, and the brownie cooks in 45 seconds. That means the whole thing can go from craving to spoon in about a minute of active work.
The recipe comes from a fudgy brownie mug cake recipe that keeps things refreshingly simple. No special equipment, no leftovers, and no pile of dishes waiting for you afterward. It is the kind of small batch dessert that makes a random Tuesday night feel a whole lot more fun.
And here is the best part. This brownie pairs amazingly with a scoop of vanilla bean ice cream. Scoop it before the mug goes into the microwave so the ice cream is ready the second the brownie comes out. Warm, fudgy brownie plus cold vanilla is a combination that does not get better than that.

Ingredients needed for this mug brownie
The ingredient list is short, and most of it is already in your pantry. Here is what each piece does.
| Ingredient | Amount | What it does |
|---|---|---|
| Salted butter | 1 tbsp | Salted butter is what the recipe calls for. If you only have unsalted butter, use it and add a pinch of salt. |
| Semi sweet chocolate chips | 2 tbsp | Semi sweet or dark chocolate both work here. |
| Egg yolk | 1, from a large egg | Adds richness and helps the brownie set. |
| Brown sugar | 1 tbsp plus 1 teaspoon | Light or dark brown sugar works. It makes the brownie sweet, moist, and fudgy. |
| Vanilla | 1/8 tsp, optional | Optional, but strongly recommended for flavor. |
| Flour | 2 tbsp, all purpose | Gives the brownie its structure. |
| Chocolate chips | 1 tbsp, optional | Folded into the batter for extra pockets of melted chocolate. |
Optional mix ins like chopped nuts can be added too if you want a fancier dessert. The source lists about 457 calories for this single serving brownie, along with 46 g carbohydrates, 6 g protein, 28 g fat, and 29 g sugar, which is worth knowing before you dive in with a spoon.
What size mug do I need for a mug brownie?
A smaller mug gives the best result. This recipe works best in a mug that holds about 8 ounces, which is roughly one cup. That size gives the brownie a nice, thick shape as it rises in the microwave.
You can absolutely use a large mug if that is what you have on hand. The brownie will look very small sitting at the bottom, but it will still taste exactly the same.
Can I double this recipe?
Yes, this recipe can be doubled. Mix the doubled batch in a small bowl instead of a mug, then divide the batter between two mugs and bake them in the microwave.
One thing to keep in mind: baking two mug brownies at the same time might take a little longer than a single mug. Start with the usual time, then add extra seconds as needed until the center looks set.
How to make a brownie mug cake?
This brownie mug cake comes together in three easy steps, and you can do all of them with one spoon.
- Start by melting the butter in the mug in the microwave. Add the chocolate chips and stir until completely melted. Microwave the mixture as needed until the chocolate is fully melted.
- Add the egg yolk, the brown sugar, and the vanilla if you are using it, and stir until incorporated. Add the flour and stir one more time, just until the flour disappears. At this point you can add the extra chocolate chips and gently stir them in, or simply skip that step.
- Cook the brownie on high in the microwave for 45 seconds. Microwave temperatures vary, so you can cook it for an additional 15 seconds if necessary.
That is it. Grab a spoon, add your toppings, and dig in while it is still warm and gooey.
Brownie add ins options:
Even though this brownie is delicious exactly as written, there are plenty of ways to dress it up. Here are a few favorites.
- Chocolate chips: Stir extra chips into the batter for little pockets of melted chocolate in every bite.
- Peanut butter chips: Swap in peanut butter chips to turn it into a peanut butter brownie mug cake.
- Nuts: Add 1 tbsp of chopped nuts to the batter before cooking for a bit of crunch.
- Molten chocolate center: Place a Lindt chocolate on top of the brownie batter in the center before microwaving, and it melts into a gooey middle.
- Cream cheese frosting: Let the brownie sit for a moment, then top it with cream cheese frosting for a tangy finish.
- Ice cream: A scoop of vanilla ice cream on top turns this into a full sundae in a mug.
You can mix and match these ideas too. Chocolate chips plus a molten center is a serious chocolate fix. Nuts plus cream cheese frosting gives you something a little more dressed up. Whatever you choose, the brownie itself stays quick, fudgy, and foolproof.
Can this mug brownie be made in advance?
No, and honestly you would not want to. This mug brownie is best made and eaten right away. It does not take more than 5 minutes to make from start to finish, so there is no real reason to plan ahead.
The texture changes as the brownie cools down. Warm, it is fudgy and soft in the middle. Once it sits for a while, that softness fades. That is exactly why the ice cream should be ready as soon as the mug goes into the microwave.
Have the ice cream scooped before the mug goes in. This brownie waits for no one.
Think of a mug cake as the dessert you make when you need chocolate in sixty seconds. If you have half an hour and want the real thing, a baked brownie recipe is worth turning the oven on for. But for a fast, single serve fix, this is the one to reach for.
Tips for making the best brownie in a mug:
A few small habits make a big difference here, especially if you are new to microwave baking.
- Mix the ingredients thoroughly at each stage, but do not over mix once the flour goes in. Stir just until the flour disappears.
- There is no need to grease the mug. Some brownie will stick anyway, and soaking the mug in a little water makes cleanup easy.
- This recipe is sized for a medium mug. In a jumbo mug the brownie will look small, though the taste stays the same.
- If you cook several mug cakes at once, add a little extra microwave time and check the centers.
- Have your toppings ready before you start cooking, since the brownie is at its best the moment it comes out.
Follow those simple habits and you will get a warm, fudgy, chocolate packed brownie in a mug every single time.
FAQs
How long do you microwave a brownie mug cake?
Microwave the mug on high for 45 seconds, then check the center. Because microwave wattages vary, add another 15 seconds only if the middle still looks wet. Stop as soon as the center is set, since extra time dries the brownie out and turns it rubbery. The whole recipe goes from mug to spoon in about one minute.
What size mug should you use for a brownie mug cake?
A small mug that holds about 8 ounces, or one cup, works best. It keeps this single serving of batter deep so it cooks evenly and rises without spilling over the rim. A larger mug still works, but the finished brownie will look small in the bottom, so watch the timing closely.
Why is my brownie mug cake rubbery?
A rubbery texture usually comes from overcooking or from stirring too long after the flour goes in. Cook it on high for 45 seconds and add 15 seconds only if needed, then stir the 2 tablespoons of flour just until it disappears. Overmixing develops gluten, which makes the brownie tough instead of fudgy.
Can you double a brownie mug cake recipe?
Yes. Stir a double batch together in a small bowl, then divide the batter between two mugs and microwave them. Two mug brownies often need a little more time than one, so start with 45 seconds and add 15-second bursts until both centers are set. As written, this recipe makes just one serving.
