Hi Bold Bakers!

Brownies are the ultimate treat. They’re packed with chocolate, have the perfect chew, and they’re easy to make. What’s not to love?

Well, sometimes you don’t want to make an entire batch of them — because while they’re good, you might have plenty of reasons as to why you wouldn’t want to make an entire pan and eat them all. So, enter one of my most popular mug dessert recipes yet — my Microwave Mug Brownie! This indulgent Chocolate Brownie in a Mug is a single-serving of heaven just for you and possibly the best, fudgiest brownie ever (other than my Best-Ever Brownies). And it only takes 1 minute to make in the microwave — and a smaller amount of ingredients you would normally need to make a full batch.

Now you have exactly zero excuses not to make a brownie for dessert tonight!

What Is A Microwave Brownie In A Mug?

Honestly, the title says it all. It’s a single serving brownie made with fewer ingredients, mixed together & microwaved right in a mug in about a minute. It’s fast, sweet, chocolatey, and everything you could want from a brownie.

How Long Does It Take To Make A Brownie in a Mug?

Everyone loves a Chocolate Brownie! Whether you are a chewy brownie lover or a fudgy gooey brownie lover, at the end of the day we all love the same cake. The fact that you can mix it in less than 5 minutes and cook it in 1 minute seems too good to be true, but it’s not! My microwave mug brownie is the real deal!

How To Make A Microwave Mug Brownie

If you’re looking for the easiest brownie recipe, this is it. If you’re looking for the fastest brownie recipe, this is also it. Here’s how you make it (and don’t forget to get the full written recipe, with measurements, down below):

  1. In a medium microwavable mug (roughly 1 cup measurement) mix together the flour, cocoa powder, brown sugar, and salt — yes, you can do this right in the mug!
  2. In to the dry ingredients add in the milk, oil, and vanilla extract and mix together until you form your batter. Combine it, but be sure not to overmix.
  3. Mix in the chocolate chips. (If you don’t want to cook them off straight away, then place them in the refrigerator for up to 24 hours!)
  4. Microwave for 1 minute 40 seconds – 1 minute 50 seconds or until it has risen and the batter doesnt look wet. (Timing is based on my 1200W microwave so your timing might vary).
  5. Serve warm with vanilla ice cream & enjoy!

The Secret To My Mug Cake & Brownie Recipes!

Mug cakes made in the microwave are no longer dried wrinkled-up cakes at the bottom of your mug. When you microwave a mug dessert, you’re actually steaming the batter so it micro-bakes up moist and delicious. Just be sure not to overcook your brownie.

Gemma,

I made this this past week and it was not something that I would make again. It was to chocolatey and a little dry and I only cooked it for 45 seconds. I think it needs a little egg. It tasted like I was eating pure cocoa.

I would hardly call this a brownie. Everything I wanted wasn’t there. I tried eating it with ice cream but it just wouldn’t offset the almost bitter taste by virtue of it being drowned in cocoa powder. Maybe if you added less cocoa powder and added some milk or eggs or something it would taste better but I’m not willing to try as I didn’t even finish eating mine and had to wash out my mouth after suffering through a few bites. Maybe some people like this sort of taste but what I would think of when I think of… Read more »

Ooh, I used 2 tbsp cocoa powder instead of three and replaced water with milk. I tasted tooooo great, just like we get in the markets! At first I overcooked my brownie, and it wasn’t edible+I didn’t like the taste of coconut oil. Next time I cooked for 1 min 20 sec and used canola oil and it took me to heaven 🤤

I’ve had my fair share of chocolately mug recipes, but this one takes the cake! Or.. the brownie?! Rich, soft, and full of delicious chocolate, how can you go wrong?! This recipe easily halves if you’re looking for just a taste — just be sure to watch that cook time! Ice cream on top is definitely not optional! 🙂

you should add milk to the mix so that the brownie is not dry. The milk will make it a bit more moist.

This is pretty good……….. But I think it would be a tiny bit better if you add milk and less cocoa powder (Mine was kinda bitter). I added some cinnamon and peanut butter and it tasted AMAZING.

ps. It took me 2 minutes to cook

Quarantine has made me bored and craving something sweet. This brownie recipe was the perfect fit for that! I put mine in the microwave for a minute and it was great! I was skeptical because it looked dry, but once I tasted it, it was very good. For next time, though, I would add a tablespoon or so of milk so that it dilutes the cocoa powder taste. Still very good though. Make sure to let It cool before you eat!

Since I don’t have any ice cream, vanila extract and no chocolate chips, I won’t buy any for the recipe bc I’m lazy😂. Will this ruin the taste ?
