A single serving keto mug cake recipe so soft, so rich, so chocolatey… and definitely not meant for sharing!
Low Carb Chocolate Mug Cake
This is possibly one of the most indulgent chocolate mug cakes you will ever try.
A brownie-like chocolate cake in a mug, made without flour, eggs, dairy, or oil.
It will completely solve all of your chocolate cravings… in less than 1 minute!
Ever since I posted my original Vegan Mug Cake Recipe –which is one of the biggest reader favorite recipes from this blog—people have been asking me to come up with a low carb or flourless version.
Over the years, I’ve experimented with coconut flour, peanut flour, and almond meal; and finally I’m happy with the results.
This chocolate healthy mug cake is everything I’d hoped it would be. You won’t miss the flour one bit!

The Best Keto Cake In A Mug
Honestly, this cake is so rich that it might be more fitting to call it a chocolate mug brownie instead of a cake.
The taste reminded me of the Ultimate Unbaked Brownies, so if you like that recipe, you will probably like this one too – it’s like eating a batch of unbaked brownies with a spoon!
You can choose to use nuts or almond flour for this keto mug cake with no egg, whatever is easier.
I’ve listed the three variations below that I’ve tried (almonds, pecans, and almond flour), but I bet others could work as well.
If anyone tries the recipe with walnuts, cashews, or cashew flour, definitely be sure to report back!
If you need it to be a keto dessert, be sure to use a keto-friendly sweetener such as xylitol or erythritol, and choose a sugar-free variety if including chocolate chips. I’m not on the keto diet, so I just added some regular chocolate chips to the top and let them melt into the warm chocolate cake.
Sometimes I make really good decisions.

Keto Mug Cake
Ingredients
- 1/3 cup almonds or pecans, or 6 tbsp almond flour (nut-free version here)
- 1 tbsp + 2 tsp cocoa powder
- 1 tbsp granulated erythritol or sugar or sweetener of choice
- pinch stevia, or additional 2 tsp sugar
- 1/8 tsp salt
- 1/4 tsp baking powder
- 3 tbsp milk of choice, or 2 if using liquid sweetener
- 1/4 tsp pure vanilla extract
- optional chocolate chips or sugar free chocolate chips
Instructions
- *If using almonds, grind them in a blender or food processor to achieve a flour-like consistency. It will be coarser than if you use almond flour (hence the almond pieces you can see in the photos), but both versions work.Combine all ingredients in a greased ramekin or small mug. Either bake in a preheated 350F oven for about 10 minutes, or cook in the microwave. If microwaving, time will vary depending on wattage and desired gooeyness. I started with 30 seconds, then added two 15-second intervals after that. The cake will look a bit gooey when it comes out, and it firms up as it cools. But there’s no need to wait for it to firm up too much – this cake is meant to be eaten straight from the mug!View Nutrition Facts
























Ok, so I tried this one out last night and WOW….it is DELICIOUS!!!!!
I needed a quick dessert that I could enjoy (with my crazy chocolate cravings during Keto) and one that my 2 yr old would also actually enjoy. This was it! It is super-rich, moist, dense, and yummy.
I agree with your comment about it being very brownie-like as it was somewhere between a cake and a brownie.
Following your recipe, I used:
6 tbsp almond flour (too lazy/busy to blend up my own nuts)
1 tbsp + 2 tsp cocoa powder
1 tbsp of Swerve Confectioners sugar
additional 2 tsp of Swerve Granulated sugar (never tried it before and thought this was a good chance)
1/8 tsp salt
1/4 tsp baking powder
3 tbsp milk
1/4 tsp pure vanilla extract
added a decent-sized handful of Lily’s chocolate chips
I topped it with Frozen Coco Whip straight from the tub (which was like covering it in vanilla ice cream) and I can easily say, I would make this every night!! I already sent this link to my family and friends who are either trying Keto or just enjoy a quick dessert 🙂
Keep up the great work!!
Yummy! Added natural peanut butter & it really made my day?
This was just the easiest, GF, DF, fastest mug cake I’ve ever made! My kiddos attacked my chocolate chips, so I folded in a serving of Kirkland Organic Natural peanut butter after the first 30 seconds. It is DELICIOUS!
How much coconut oil goes in?
Thanks for recipe it got me thru my GD pregnancy x
Hi! It looks like the recipe doesn’t call for coconut oil, but I don’t see why you couldn’t use a little for some of the other liquid in the recipe if you wanted to add some?
Macros are incorrect. Net carbs are 6.7g made with Swerve and almond meal flour, heavy cream.
Hi Kate, macros will just depend on what specific ingredients you use 🙂

Sooo good. Followed the recipe as written using almond flour and 1 tbsp lakanto sweetener. The result was like a dark chocolate cake–not overpoweringly sweet but satisfyingly chocolatey. Thanks for this recipe!
I made this but added about a tbsp of applesauce and it was perfect! Super moist! I baked it in my toaster oven in two mini pie dishes.
I used almond flour — it was fantastic! Nuked it for a minute. Couldn’t really wait to let it set, so in the middle it was more like a cake batter mug cake. But I’m not complaining! 🙂
I made this last night and ate two of them. OMG was it good. However, I woke up with cramps and felt like a massive colon blow was about to erupt. If you need a colon cleans…. this item is for you.
Oh dear, not nice 😯 My lads are eating mostly keto now as that’s what I’m eating, but I’m careful with how many goodies they consume in a day when it comes to the almond flour – it’s really, really full of fibre! They both learned the hard way! 😂 Also, I’m a bit sensitive to some sweeteners (I think the artificial ones are to blame) so on occasion have experienced a little (a lot!) colon-cleansing myself. Although I seem to be okay with the ‘keto’ sugars, I still consume them in moderation (now!)
Thanks for an amazing recipe full of chocolatey yumminess!! More than satisfied the need for comfort food on a cold, rainy day in England.
Holy moly this was delicious!
This is so delicious. I put it in the microwave for 1 minute and it’s nice and gooey.
Looks delicious, and was looking for a flourless mug cake recipe for ages! Thanks and looking forward to trying!
My mug cake Was good but came out dry loose. What did I do wrong
Same! It came out as moist crumbles – not a cake!
Thank you so much for sharing this recipe. It was soooo delicious. Never coming back to regular brownies again!
This cake is incredible! I was sceptical because I didn’t think it would work without an egg. I skipped adding the chocolate chips and added some frozen raspberries instead. It’s rich, goey and just delicious. Very moreish, loved it!
Tasted rich of chocolate. If you let it cool, it’ll be more fudgey in texture. For me, the almond flour made the brownie very grainy. I would reduce the portion size. and might try it with cream or heavy whipping cream next time for a smoother rich taste.
Great mug brownie!
The video shows adding coconut oil but that is not in the written recipe?
