A delicious one minute chocolate brownie mug cake that bakes up in your microwave. Enjoy this simple low carb gluten free brownie recipe for a quick snack.
You may have noticed the lack of sweet recipes recently. Well, I’m trying to cut back on them.
The problem with the sweet recipes is that typically I’m the only one who eats them unless my parents stop by for a visit. My husband and kids do not follow a low carb diet.
Although my son will eat just about anything, he is away at college so he isn’t home to eat the leftovers. So, I usually end up eating the whole recipe over a week or so by myself. When possible, I do freeze leftovers in individual servings, but you can only shove so many low carb treats in the freezer.

I have never been big into the mug cakes, but I do love the idea of baking for only one. For my birthday this year, I came up with a single serving microwave baked birthday cake.
It was a great way to enjoy a celebratory cake without overdoing it. In fact, that little cake ended up being four treats for me as it was such a filling cake.
Lately, I’ve been craving chocolate. Most of the time, I just pick up a few Lily’s bars at a local grocery store. Last week, I decided to try baking a low carb one minute chocolate brownie in the microwave.
I had some Sukrin Fiber Syrup Gold in the pantry and chose to make it with that. I tried it later with regular granular Sukrin:1 and that worked just as well. However, as you would expect, the one made with the syrup was not as crumbly.
To make this quick little low carb one minute chocolate brownie mug cake, you start out by melting a little coconut oil with the fiber syrup or granular sweetener. It only takes about 15 seconds or less for the coconut oil to melt into a liquid.
Then, you add the rest of the ingredients to make the thick brownie batter. I found that it works best if you combine the dry ingredients first, but you don’t have to if you’d rather not dirty another dish.
I like using dark cocoa, but you can use whatever cocoa you prefer. If you like a really moist fudgy brownie, you’ll want to undercook it. Fully cooking the one minute chocolate brownie batter in the microwave for about a minute or more results in more of a mug cake texture.
This ends up being a rather large one minute chocolate brownie. You can certainly eat the whole thing if you’d like. I’d rather eat half and save the other half for later. It also ends up being better with respect to carbs/serving if you split the brownie into two servings.
You can enjoy this one minute chocolate brownie plain right out of the microwave. However, I like to top the warm brownie with a little sugar free whipped cream from my whipped cream dispenser.
This one minute chocolate brownie mug cake is a low carb treat that you can easily whip up any time a snack craving hits you. It’s so easy that it’s almost as simple as ripping open an unhealthy Little Debbie snack cake which is what my husband does to satisfy his snack cravings.
The net carbs are the same regardless of whether you use a fiber syrup or erythritol based granular sweetener. Some people have reported that they are sensitive to the carbs in the Isomaltooligosaccharides (IMO) based fiber syrups.
So, you may want to test your blood glucose levels to make sure this sweetener doesn’t cause insulin spikes for you. Although they don’t seem to bother me, I use the fiber syrups in moderation. Even though these fiber carbs are said to be negligible, I don’t like taking in more than I have to.

Connor says
I replaced the syrup with organic honey so there are about 17 more carbs but it still tastes great!
Lisa says
Honey is very similar to the syrup so it should be just about the same other than the added carbs.
Rachel says
This was so great! I doubled the vanilla and used an egg with one tbls of granulated sweetner and omitted the baking powder (because I don’t have any right now!) I really wanted a chocolate treat and this hit the spot. Thank you!!!
Lisa says
Thanks for sharing how it worked out for you!
Barbara says
I love this recipe!! Turns out perfect everytime! We use 1 egg & sweetener making it now,LOL
Thank you!
Lisa says
It does come out much better with the added egg.
SIUE Teacher says
How much Swerve should I use? I tablespoon? Please help thanks
Lisa says
It would be the same, 1 tablespoon. And, it helps to add in an egg if not using the syrup.
Alissa says
Does this recipe taste like a regular mug cake or no? Terrified of making more chocolate dessert because of my epic failure brownies. We couldn’t even swollen them they were that awful!
Lisa says
I found it more like a brownie. You may want to add a bit more oil if you don’t want to use the syrup.
Jacob says
No mine turned out horrible. Will not use this recipe again. I had to keep cooking it to try and get it solid. It over ran out of my large coffee mugs and then left about 1/2 of the mug with the brownie in it. It was still wet and runny after 3.5 mins of microwave and my microwave was filthy from the over run. Next time I will throw an egg in my re iOS so I know it will turn into a
Good solid treat.
Lisa says
This recipe works best with an egg if you aren’t using the fiber syrup sweetener. I’ve never had an issue with it cooking. There must be a difference in ingredients.
Frances says
I have looked for a mug cake or brownie that would taste real and I tried this but it was bitter so I changed a few things and it came out wonderful every time. It taste same as brownie and turn out same every time I have made it which is a lot. I put (1) teaspoon coconut oil ,1/2 teaspoon butter and (1) tablespoon Sukrin gold fiber syrup in mug and heated in microwave 17 seconds to melt. I then added 1/2 teaspoon vanilla extract and more sweetener to your taste ( I added 7 Splenda packets) and mixed well. I then added my 2 tablespoon heavy whipping cream, 1 1/2 tablespoon cocoa, 1/2 teaspoon baking soda ,2 teaspoons almond flour and mixed really good. I put in microwave 67 seconds and then let cool for a few mins. Very very good.
Lisa says
Thanks for sharing! I may add something in the notes to check out the comments so others don’t miss this. I’ll give it a try too!
Janet says
I made this Mug cake without the syrup because I didn’t have any and with 2 TBSP whole milk instead of the cream. I cooked it about 70 seconds – It only rose about 2 inches but was moist and delicious. Just what I needed to fix that craving. I ate the whole thing.
Lisa says
I like the moist and delicious part!
Lisa says
Hi Lisa,
I made this mug cake today and it was great! I have tried quite a few and they were close to horrible. I did use the coconut flour and I used 1 tablespoon of Swerve (Erythitol). It was not crumbly at all. I may use a little bit more coconut oil next time, but we will see if that makes any difference in texture. I put a bit of whipped cream on top. Very happy!
Lisa says
I find Swerve does work a bit better than the stevia based bulk sweeteners.
Kelly says
Made this exactly as you outlined. I didn’t have the syrup you used so used some sugar free maple flavoured syrup instead. It was so good, my perfect mug cake search is finally over. I cooked for 45 seconds. Thank you for your effort to share your recipes. Much appreciated!
Lisa says
I was wondering if it would work with low carb pancake syrup. I’ll have to try that as it would be lower in carbs if using Walden Farms maple flavored syrup or a homemade version.
Cathyo says
I doubled coconut oil to 1 tsp, cut Special Dark Hershey’s to 1 Tbsp, , used 1Tbsp Stevia in the Raw, and a couple drops of liquid sucralose. Cooked for 50 seconds and it was crumbly, but the flavor was divine….especially with a bit of whipped cream. I’ll try 40 seconds next time. Thanks for the recipe!
Lisa says
Thanks for the info!
Machelle says
I doubled the coconut oil, vanilla and splenda. It was great. Best tasting mug cake. It was crumbly. I may add 1/4 to 1/2 egg next time. I love the taste.
Lisa says
Thanks for letting us know how you made the recipe and how it turned out!
judy says
can another type of oil be substituted for the coconut oil such as olive oil or canola oil. also can another type of flour be substituted such as almond flour or oat flour
Lisa says
You can use another oil, but other changes may be needed if you sub the flour.
Rachel says
I subbed the coconut flour for almond flour because that was all I had. Measure for measure it was 8 tbsp of almond flour and it turned out great!
Lisa says
Good to know!
Marcia Wilcox says
Hey, Lisa, thanks for all the awesome recipes! I love this site! However, you may want to look at this study: http://easacademy.org/trainer-resources/article/isomalto-oligosaccharides
It says in a nutshell that IMO’s do indeed get digested like carbs, so if a low-carb dieter uses Sukrin a lot, they might want to know that. I’ve had good luck with erythritol, the main drawbacks being that it needs a sweetness-boost (I use stevia) and it has that sort of cooling effect which doesn’t bother me but might bother some. At least it doesn’t cause me gastric distress like some low-carb sweeteners!
Lisa says
I have known about the IMO carb issue. That’s why I only use very small amounts now. It’s too bad because I used to love Quest bars but rarely eat them now.
Kaylyn says
Wow! I just found a new favorite mug cake recipe! I used 2 tbsp of Swerve for the sweetener (which might have been a little too much, but I have a big sweet tooth). I threw in some Lily’s sugar free chocolate chips and topped it with a cream cheese frosting. So good! Thanks for the recipe!
Lisa says
The addition of chocolate chips certainly helps with any dryness issues. Great idea!
Denise Sowles says
We couldn’t eat this either despite several attempts. Didn’t have that syrup so used a couple different sweetners and added more coconut oil. I used regular cocoa the second time and it was still very bitter and every batch was dry and gritty. It sounds so good I’m willing to do some more experimenting – that’s another benefit to mug cake recipes. If it fails you aren’t wasting a ton of ingredients.
Lisa says
I need to rework this one with more common ingredients. It was great with the syrup. You can drop a piece of low carb chocolate in it for a molten treat. That may help.
Chanell says
Mine turned out with perfect texture, but it is not edible š Any idea why it would be super bitter?
Lisa says
You may just prefer it a little sweeter. I’d add a few drops of stevia liquid or a little more of your preferred sweetener.
Linda says
I had the same problem as Stef. Perhaps an egg needs to be added?
Lisa says
Are you using the fiber syrup or granular sweetener? I’ve made this several times with the syrup and it’s very good. With the granular, it more crumbly. I’m going to work on this recipe a little more and post an update with how to get better results. I’ll try an egg, but I’m thinking a little glycerin may also help since the syrup works better.
Sara says
Hi, I made your recipe. I used granular erythritol and it was just all crumbly so I added 1 large egg and whipped everything up together. I microwaved for 1 minute and it was perfect. I put a little cream on top to cool it down. Probably would have been fine at 45 minutes too.
Lisa says
Egg will hold it together if you don’t use the fiber syrup.
Stef says
I decided to make this to bring to work for my afternoon snack. I followed the recipe exactly, however, the final mixture was VERY dry, and even after adding more cream, it was still crumbly dry. I stopped at about 2.5T cream thinking that perhaps I just needed to cook it, but it came out all crumbly. I didn’t use the fiber syrup, but instead used 1.5t of an erythritol/stevia mixture, and hershey’s dark cocoa. It’s still yummy and I’m still going to eat it, but wonder if I should have continued adding cream until the mix was more gooey?
Lisa says
The batter should be very thick. You don’t want to add too much cream. Since you used a smaller amount of sweetener, it would be better to add a little more coconut oil or butter to the batter rather than cream for bulk. Also, cooking time is a factor. The shorter time, the denser it should be.
