A moist, gooey and fluffy chocolate brownie ready in less than one minute and completely low carb too! Made with no butter, oil, grains, or sugar, this healthy mug brownie is paleo, vegan, gluten-free, sugar free, keto-friendly, low calorie, dairy free and has a tested oven option!
I’m always up for a good mug cake recipe, including a low carb vanilla mug cake, keto blueberry mug cake, and this healthy low carb brownie.
1 Minute Low Carb Brownie
Whenever my chocolate craving strikes and I’m watching my carbs, I always turn to this gooey keto brownie to satisfy my cravings.
This brownie in a mug is moist, gooey, and perfect single-serve dessert or snack to enjoy anytime! It also only takes less than a minute to whip up, or under 12 minutes if you bake it in the oven!
Traditional mug brownies tend to use plenty of sugar, oil, and butter to achieve a brownie-like texture, but in my version, we use healthier and easy to find pantry staple ingredients, that you’d probably have on hand now!
Bonus? This sugar-free keto mug brownie isn’t just low carb… if you check out the ingredients, it’s also perfect for a paleo and gluten-free diet. It’s also made with NO eggs, so my vegan friends, you are covered too!
How to make a keto brownie in a mug
- Almond Flour– I used blanched almond flour, but you can also use almond meal.
- Keto Sugar Substitute– Either erythritol or monk fruit can be used. You can also use a sugar free baking blend, like Splenda.
- Cocoa Powder– Unsweetened and good quality. If your cocoa powder has clumps, be sure to sift it first.
- Baking Powder– Leavens out the mug brownie and gives it some rise!
- Almond Butter– Drippy and smooth almond butter gives the mug brownie a buttery and moist texture. You can use any smooth nut or seed butter.
- Milk of choice– Any milk works, I used unsweetened almond milk
- Chocolate Chips of choice– Optional, but highly recommended!
In a small mixing bowl, add your dry ingredients and mix well. Then, you’ll want to whisk together your almond butter with the milk, until combined. Next, you’ll combine the dry and wet ingredients together, and mix until combined. If using chocolate chips, fold them through with a spoon. Finally, microwave the mug cake for 60-90 seconds, until the brownie is just done. Allow the brownie to cool for a minute, before enjoying it!
Can I make this keto chocolate mug brownie in the oven?
Easily make this mug brownie in the oven if you don’t have a microwave or choose not to use one. Simply grease an oven-safe 6-inch ramekin (it can be bigger) and bake the single-serving keto brownie for around 6-8 minutes at 180C/350F, or until just cooked.
Should I use the oven or the microwave?
Time is the key factor here, but depending on which method of baking you choose, they both actually can result in a different texture. The pictures shown within the post is actually made in the oven. If you check out the texture closely, it’s quite tender on the outside and fluffy and moist on the inside.
This wouldn’t be possible in the microwave, BUT it takes a fraction of the time. However, if you want to use the oven AND have a really gooey center, you’ll just need to remove it a little earlier, when it just begins to firm up on top.
Can I add an egg if I’m not vegan?
You can still achieve a gooey and moist center without the need for eggs. Whether or not you follow a vegan lifestyle or not, you can do this.
If you don’t follow a vegan diet and you want to have a fluffier, cakey brownie mug cake, add either 1 whole egg or egg white.

If they had used kitchen experiments in my high school science classes, I might have paid better attention.
I always use the microwave version. I am lazy and impatient. Also I always use the full egg. I know it might diminish the fluff factor but I hate to waste the yolks.
This post reminds me of the one time in chemistry class when my teacher used flour to demonstrate a dust explosion and (not for the first neither the last time) got the measurements wrong… it was AWESOME!
Hahaha…I bet your science teacher really loved having you in class! I hear ya, though. I actually did like science…well, some science. Chemistry was ok, and I loved Physics. But man did I hate Biology. I’m just not into medicine and guts and stuff. No thank you. But I am a huge fan of this 1-minute brownie. And I need to spend the next 60 seconds making one…and then the next 10 seconds after that eating one. 🙂
I am not a youngster (LOL) and not a sports person, never used or even heard of protein powder,
found some on Amazon,(UK) seems to be for sporty people
is there a something I could substitute for this?
Hi Pauline! Don’t be silly, you are a youngster 🙂
You can make my 3 ingredient flourless brownie- No protein powder needed! https://thebigmansworld.com/2016/12/21/healthy-3-ingredient-1-minute-flourless-brownie/
If I use a plain protein powder (as opposed to chocolate) should I add more cocoa?
Hi Kathy! that should be okay- You might want to add some extra sweetener 🙂
Wonderful- thanks! 🙂
Sorry, I didn’t see how many carbs are in each one of these. How many carbs are in each one of these
Hi Dana! I didn’t include them because it is dependent on what protein powder you use. 🙂
I wonder, how many calories are in one of these?
Hi Chris! If you go to myfitnesspal and plug in the ingredients, it will provide it for you 🙂
Has anyone worked out the carbs content. Why do so many ‘low carb’ recipes only calculate calories, not very helpful for those of us trying to count carbs?
Hi Wendy! You can use an online calculator to give you an accurate macronutrient breakdown. Enjoy!
It looks so yummmy but can i use oat flour or whole wheat flour because coconut flour is not available in my country and thank you
You can try 🙂 It won’t be as fluffy 🙂
Any chance you can start posting the nutritional facts (calories, carbs, fat, protein) on your recipes??
Hi Gina! I have started sharing a general calorie count, but if you would like the specific nutritional facts, you can use myfitnesspal or another calorie counter 🙂
Arman, I’m in heaven!!!!! This was oh my tastebuds delicious!!!!! This is going to be my go to when a girl needs that,,,,,chocolate please kind of day!!!! Thanks so much for all the great recipes you post for us. Keep up the great work…..hugs, Dianna
Can you replace chocolate protein powder with chocolate (cocoa) powder
I don’t think so, the protein powder lends a unique texture 🙂
