This keto mug cake is so rich, decadent, and full of chocolatey goodness. And since this is a flourless keto mug cake, you don't need any almond flour or coconut flour to make it! Along with that, it is ridiculously easy to make - it takes just 1 minute to make this keto mug cake in the microwave.
The Best Keto Flourless Chocolate Mug Cake
When you're craving something rich, sweet, and chocolatey nothing beats this keto mug cake.
Honestly, this has to be my all-time favorite keto mug cake - it can be made in a flash, only requires a few ingredients found in every kitchen, and it is just oh-so cakey.
And since this is a single-serve mug cake, portion control is built right into the recipe, and you can enjoy the entire thing for only 4 NET CARBS!
Now, something I think puts this above other mug cake recipes is that you can use a nut butter of your choice instead of flour - it just gives it an unmatched flavor and consistency.
Plus, you have the option of making this mug cake quickly in the microwave, or you can bake it in the oven. No matter which way you choose, this mug cake turns out super soft, cakey, and moist.
INGREDIENTS FOR THIS KETO MUG CAKE
So, as I've mentioned, this mug cake recipe doesn't use any flour. And the ingredients that you'll need are some of the most common keto baking ingredients.
Check them out:
- 1 Large Egg
- 3 Tbsps. Nut Butter Of Choice
- 1 Tbsps. Unsweetened Almond Milk
- Just less than 3 Tbsps Confectioners Swerve
- ¾ Tbsp. Unsweetened Cocoa Powder
- ¼ Teaspoon Baking Powder
- Pinch of salt
I always have these ingredients on hand, so this mug cake comes in clutch when I crave a chocolate dessert and want it ASAP.
And, honestly, I use a lot of these same ingredients to make this keto fudge, this low carb chocolate lava cake, and these keto candy bars. So, if you don't have some of them on hand, I highly recommend picking them up.
Nut Butter Options
Now, you may have noticed that you can use any nut butter that you want in this mug cake. Just make sure you use one with no sugars added to it to keep the carbs as low as possible.
Oh, and if you use peanut butter, you'll make a Reese's mug cake! Were you already thinking that, or did I just blow your mind? It's definitely one of my favorite ways to make this cake!
Sweeteners
Along with being flourless, this is, of course, a sugar-free mug cake.
And to sweeten it up without adding any sugar, you can either use Confectioners Swerve or Lakanto's Powdered Monkfruit Sweetener.
Both of these have 0 calories, 0 sugars, and are just as sweet as sugar!
HOW TO MAKE THIS KETO MUG CAKE
As you know by now, I love how easy this mug cake is to make.
There are just a few simple steps, and you'll have a rich and decadent treat in no time.
STEP 1: COMBINING THE INGREDIENTS
The first thing that you will do is add all of your ingredients to a measuring cup.
Then mix your ingredients with a rubber spatula until they are well combined and a thick, chocolate batter forms.
And I know the batter looks so enticing to eat, but try to fight the urge for a few more minutes.
Anyways, next, coat an 8 oz. ramekin with baking spray and pour in your batter.
By the way, you can definitely add the ingredients to the mug you plan on cooking your cake in from the start, but I think the cake turns out better if you use two separate mugs for the process - one for mixing, and one for baking.
STEP 2: COOKING YOUR KETO MUG CAKE
Now, once the batter is in the ramekin, you'll want to cook it in the microwave for around 45 seconds. Having said that, that's the cook-time for a standard 1100 Watt microwave.
Just keep in mind that the microwave time will vary depending on the Wattage of your microwave.
Also, it's best to undercook your mug cake slightly, as it will continue to cook a bit once you take it out.
And if you want to cook this mug cake in the oven, bake it at 350°F (177°C) for around 10 minutes. You can test if it is done by sticking a toothpick in the center of the cake and seeing if it comes out clean.

This was the best keto mug cake I’ve ever made!!
Soooo good!!! It wasn't dry like most mug cakes I've tried. This is definitely my favorite mug cake I've made!
Glad you loved it!!
I'm going to try this , it's very simple
I'm hooked on this cake. Satisfies my sweet tooth completely. My food must taste delicious as well as nutritious so don't think I am easily impressed. Can't wait to serve this to company. I've been making it with mixed nut and seed butter for variety. M
I used walnut butter added extra 1/4 tsp cocoa, microwaved at 10 sec intervals because my ramekin was too small and only for 40 seconds. DELICIOUS.
Would coconut butter work?
Say maybe you could use all coconut ingredients and make a coconut cake.
Please let me know if you think it will work?
Coconut flour won't work for the cake.
I love it!! Very soft texture and I used peanut butter and made a vanilla whey protein syrup to cover it! Yummy
Wonderful recipe! Have made this MULTIPLE times and it has helped a sugarholic and cake lover like me stay on course with Keto. Often make it right after my meal - it is done SO quick. Love it - thank you so much.
Awe, that's awesome!!
Absolutely incredible!
Wow, I can’t believe this worked so well! Really, so delish ❤️🔥
Just did this recipe and to say as a pregnant and diabetic woman this was perfect and it did not spike my blood sugar!! I will definitely be using this a lot more
Such a great recipe! I used almond butter and added a little almond extract. Tasted so decadent, but incredibly healthy! Thank you, I was about to fall off the Keto wagon!
Since being on a keto diet I’ve been craving chocolate. My husband surprised me yesterday by making me this cake and I am extremely pleased with it. So satisfying. I’m amazed it contains no flour. It will become a staple. Thank you!
I have made this a few times. Sub brewed coffee for the almond milk and it is even better.
I have never made a keto cake that I liked. I just can get over the grainy coconut/almond flour but this cake was really good! I’m making it again tomorrow and will top with keto whipped cream.
Excellent recipe! I love it! Now I just need a recipe to make an entire batch to put into cupcake tins to take to the office:)
I made 3 muffins out of the batter and baked 15 minutes at 150 Celsius. Turned out great, thank you for this recipe!
Awesome! I doubled the mix, and added a few pecans and chocolate chips.
I’m in chocolate heaven!
