Are you ever just craving brownies but don't feel like making a whole pan of them? That's how I've been feeling a lot lately, so I decided to make this Fudgy Mug Brownie! It's a single serving fudgy brownie made in a coffee mug that's sure to fulfill your chocolate craving! No oven is required and it'll be ready in less than 10 minutes!
What You Need to Make This Recipe
Ingredients:
- Chocolate: you can use semi-sweet or dark chocolate, chips or chunks.
- Unsalted butter: this will be melted with the chocolate in the first step.
- Granulated & light brown sugars: if you want to just use one over the other, that's fine, just make sure it's adding up to ¼ cup.
- Egg white: this is going to help give that fudgy texture!
- Flour, cocoa powder, salt: the dry ingredients that provide structure and flavor for the brownie.
Equipment:
- 11-12 ounce mug: you don't need any mixing bowls or anything, everything will go straight into the mug! I used the Instagram famous mug from Target!
- Fork: this is all you'll need to mix the ingredients together!
Recipe Notes
This is the easiest, quickest and tastiest brownie recipe you'll ever try! It's like a mug cake except better because it's gooey & fudgy! If you want a full brownie recipe, I recommend my Samoa Brownies!
The first step is to heat the chocolate with the butter in the microwave. When the butter is melted and the chocolate is soft, take it out and stir it until the chocolate melts completely. Then you're going to stir in the sugars, followed by the egg white. Mix these in real well until the batter is slightly thick. Finally, stir in the remaining dry ingredients and then microwave it for about 30 seconds at half power. The brownie should come out looking gooey and bubbly on top.
Microwave times will vary as microwaves are pretty inconsistent. If you scoop out a bite and it's too gooey, put it back in the microwave for a few more seconds. If it's too cakey, it was probably heated too long or at too high of a power.
Tips & Storage
Sure! You can gently mix them in after adding the flour mixture.
If it comes out more like a cake than a fudgy brownie, it was probably overheated. Try reducing your microwave's power or the heating time.
It's chocolatey and delicious on its own, but it's also super tasty topped with a scoop of ice cream, peanut butter, caramel sauce, or whatever your favorite brownie toppings are!
I haven't tested this with gluten free flour, but I am guessing that it would work just as well. Please let me know if you try it this way!
I recommend eating it all right away, but it can be stored at room temperature for 1-2 days. It'll be very hot out of the microwave so be careful not to burn your mouth!

I absolutely adore this recipe. I wouldn’t consider myself a chocoholic. However, once in a while I have a very persistent craving. I found this recipe and decided to give it a whirl. Oh my GOODNESS it was divine! I’ve made it a handful of times since and it has never failed. A huge hit with the kids and husband as well. Thank you!

Love the flavor and texture of this! I had this during the middle of a busy work day (thankful for work from home) and it instantly eased my stress. Delicious flavor, will be eating again.

One note to this recipe - you need to let the chocolate/butter cool before you add the egg white or you'll have cooked eggs in your brownie. Yuck..
Also, you don't need as much sugar as the recipe calls for to make this a little less horribly unhealthy.
Kayla says
Hi Kara, I appreciate your feedback and I'm sorry this recipe was not a success for you! The chocolate & butter should only be heated to the point where they melt and stirring in the sugars helps cool it down, but I understand your comment and will update the recipe to clarify this step. As a dessert blog, my main focus is not healthy recipes and sweetness is a personal preference but I'll also add a note about decreasing the amount of sugar. Thank you!

What is 50% of microwave power?
Kayla says
This is changing the microwave Power Level setting to one half. Usually you can change it by entering the cook time and then hitting "Power" and then "5", but it varies by microwave.
