Best Keto Chocolate Cake
Do you ever have a time when you just need a little chocolate fix? Rather than make a whole cake you can simply make one serving so you can have perfect portion control, because sometimes even keto desserts are hard to resist, am I right?
This chocolate keto mug cake recipe has been one of my most popular recipes since I first posted it back in May of 2014. I felt it deserved a front row seat this month and I added an easy video below for you!
For chocolate lovers everywhere this chocolate mug cake recipe will curb that sweet tooth craving.
Besides this beauty, I've got a bunch more mug cake recipes you might enjoy, like my Carrot Mug Cake, Cannoli Mug Cake and my Tiramisu Mug Cake, or maybe lemon mug cake is more your speed.
Easy Keto Chocolate Mug Cake
The best part about this sugar-free mug cake made in a single serving is that it is just enough to enjoy a sweet treat without feeling tempted to eat more, since there isn't any!
With just a handful of ingredients you probably have on hand, you can make it whenever you want. You can also enjoy it whether on a keto diet or you follow a low-carb lifestyle, as it's high in fiber and protein, sugar free and low in carbs!
You can certainly just eat it right in the microwave-safe mug you make it in, but for picture purposes I popped mine out after it cooled slightly. I did spray my dish with nonstick cooking spray before pouring in the batter just in case, but if you are eating it right in a large mug no need for that.
Microwave or Oven Mug Cake
If you want a successful recipe with rich chocolate flavor, the best thing you can do is not overcook your mug cake.
Microwave cook time will vary so you may need another 20-30 seconds to make sure it cooked through, just check with a toothpick, if it comes out clean you're good to go.
You could also make this in an oven if you prefer, see directions below.
I'm really in love with this moist cake and hope the next time you have a chocolate craving you try my recipe.
I adapted from some of my tasty mug cakes and kept out the coconut flour I used in those recipes to make this more dense and unlike a muffin texture. I'm super happy with the results and I hope you'll try it and come back and share how you liked it, I love reading comments like that!
How to Make Keto Chocolate Mug Cake
Simple Ingredients
Egg, unsweetened almond milk or you can also use heavy cream, low-carb sweetener, ground flaxseed or almond flour, unsweetened cocoa powder, baking powder, salt.
Optional toppings like sugar-free chocolate chips and sugar-free whipped cream.
Microwave Directions
Spray your large mug or ramekin with cooking spray. Whisk the dry ingredients together. Mix in the wet ingredients. Microwave for 45 seconds, up to 1 minute. Check center of cake with toothpick. If it comes out clean, it's done.
Oven Directions
Preheat your oven to 350 degrees F. Follow directions to prepare cake.
Place in preheated oven for 10 minutes. Check center with a toothpick. If it comes out clean, it's done. If not bake an additional 5 minutes then check again.

Sugar-Free Keto Toppings
As you can see from the pictures, I enjoyed the whole cake topped with sugar free whipped cream, some melted sugar-free chocolate chips. It's the perfect size and I was truly satisfied!
Swapping Low-Carb Sweeteners
You can use your favorite sweetener of choice, you know I'm a huge fan of liquid stevia, but anything you like will work. If you don't have chocolate stevia, you can use vanilla or plain or even powdered. I would use only ¼ teaspoon if it's the pure extract or 1 packet if that's all you have.
A full dropper of stevia yields about ⅛ of a teaspoon, sometimes I can get ¼ teaspoon but never more than that. So if you don't have a dropper in your liquid stevia, measure out ¼ teaspoon, depending on your brand that may not be sweet enough for you. You may need ½-1 teaspoon if you like really sweet cakes.
You can use my sweetener guide and conversion chart to determine how much sweetener to use to replace the stevia I used in my orginial recipe.
UPDATE: I've swapped the ground flaxseed with the same amount of almond flour and it came out just as good.

Donna
I substituted sorghum flour for the flaxseed, and sweetened with sweet and low. Came out great! I'm looking forward to getting the flaxseed and stevia to try the original recipe. So easy! Thanks!
Brenda
thanks for sharing you substitutes!
Jennifer
The cake was so good! I didn't have liquid stevia so I added a few chocolate chips to the cake. Same thing for the syrup, I melted the chocolate chips along with the rest of the ingredients. Sooo delicious!
Janet
Can I use the liquid vanilla stevia instead of the chocolate stevia?
Brenda
I think that will work fine.
Karen
This sounds a great recipe and will give it a go. Never used stevia before, but have run out of good recipes where the sweetness just comes from dates or bananas. It's good to have an alternative. Thanks!
Brenda
Thanks Karen!
Deborah
Ugh came out so bitter it was nearly inedible (cake and syrup both). Wonder if it was my cocoa- which brand do you use? I used Hershey's. Thanks in advance for any pointers- I want to try again!
Brenda
Sorry that happened! Which brand of stevia? Liquid, powdered, packets or pure extract?
Deborah
I used liquid- Now Better Stevia. I think maybe it was too much cocoa powder- perhaps with the Hershey's I should use less?
Maria
Mine was also inedible.
Marian
I dont have ground flaxseed!!!! Now what??? This is an emergency!!!! Please help 😀
Brenda
Try coconut flour or almond flour in it's place.
Charlotte Moore
I just made this. It was real bitter seemingly from the stevia. I wish I had only used half to try. It rose good and was light in texture. Amazing it would be so much like cake with no flour.
Brenda
What brand of stevia do you have Charlotte?
Charlotte Moore
I have Sweet Leaf Sweet Drops.
Brenda
I'm going to edit the recipe to specify the full dropper is about 1/8 of a teaspoon so maybe 1/4 teaspoon just wasn't enough sweetness for you. Just measure it out next time, also sometimes the cocoa powder you are using an cause a bitter taste especially being unsweetened. Make sure it's a good brand of cocoa.
Kerry
An 1/8 of a teaspoon is half of 1/4 teaspoon. If you want to double 1/4 teaspoon, that would be 1/2 teaspoon.
Miriam @ OvertimeCook
This looks too good to be true! I can't wait to try it.
Melissa from HungryFoodLove.com
Sugar free and looks this good! I need to try this beauty. Thanks!
Rose | The Clean Dish
I know *exactly* what you mean - sometimes it has to be chocolate cake and nothing else! I love that you use flax seeds. So many people don't (I guess many just dislike the flavor) but I'm sure it works perfectly for this cake!!
Charlotte Moore
I really need to try this. My husband LOVES chocolate. I have made a couple mug cakes/muffins. Some good some not so good.
Thanks!!!
Ginny McMeans
Okay, I love you!

Wait - ONE MINUTE?!?!? You are a genius!!!
Lana @ Never Enough Thyme
This is really perfect for empty-nesters like us. Sometimes I'd LOVE to have some chocolate cake but a whole one would just be wasted on the two of us.
Crystal Rose
Can you suggest a substitute for the liquid chocolate stevia? I have powdered stevia, agave, honey, maple syrup, carob, and cocoa powder. Would one or more of those work? (I'm always wary of switching liquids for dry ingredients.)
Maria
I would go powdered stevia, Crystal. That's worked for me in the past! x

This looks too good to be true!
Angela {Mind Over Batter}
I love adding flaxseed to everything. It's so sneaky! *Insert sinister laugh* I've never tried making a mug cake, but I seriously need to jump on this one minute cake bandwagon. For serious! YUM!
Carla
I only have stevia packets. What is the equivalent for the syrup?
Ashley @ Wishes & Dishes
I saw this on Pinterest and immediately fell in love! Great idea!

1 minute?! I am going to put a stopper on and gonna race against it. Looks yummilicious! 🙂
Kay-M
The '1 minute' refers to the cooking time, not the prep time...LOL

I love adding flaxseed to cakes! Makes such a fluffier batter. Looks great!

I want to eat this entire thing. And it's sugar free, so that counts for something, right?
Librarian Lavender
