What Type of Chocolate to Use
You will need unsweetened cocoa powder and sugar free chocolate chips for this recipe.
How to Make Sugar Free Chocolate Mug Cakes
Detailed measurements and full instructions can be found in the recipe card at the bottom of this post.
- Combine butter, eggs, and vanilla in a bowl.
- Combine almond flour, baking powder, and unsweetened cocoa in a separate bowl.
- Combine the dry and wet ingredients. Fold in the chocolate chips.
- Microwave for 60-90 seconds.
What Type of Sweetener to Use
I used granulated monkfruit sweetener. It’s organic, zero calorie, and zero carb.
To keep this sugar free you will have to use a sweetener that is free of refined sugar. If you want to use refined sugar, you can use the same amount noted in this recipe (for monkfruit).

Easy, Sugar Free Chocolate Mug Cake
Ingredients
- 2 tablespoons blanched almond flour
- 1 tablespoon unsweetened cocoa powder
- 2 teaspoons sweetener
- ¼ teaspoon baking powder
- 1 egg
- ½ teaspoon vanilla extract
- 1 tablespoon butter Melted, measured solid.
- 2 tablespoons sugar-free chocolate chips
- cooking oil I used olive oil.
Whipped Cream (Optional)
- ½ cup heavy whipping cream
- 1 tablespoon sweetener
Instructions
- Mix all of the dry ingredients in a medium bowl (almond flour, sweetener, baking powder, unsweetened cocoa powder)
- Combine and mix the wet ingredients (egg, vanilla, and melted butter) in a separate bowl.
- Add the wet ingredients to the bowl with the dry ingredients. Mix well until fully blended.
- Fold in the chocolate chips and stir.
- Spray a mug with cooking oil. Add the mixture to the mug.
- Microwave for 50 seconds to 1 minute. I timed it for 50 seconds because I wanted a really moist cake. With 1 minute it will be slightly more firm, but still moist.
Whipped Cream (Optional)
- Add the whipping cream to a mixing bowl. Use a hand mixer and mix for 2 minutes. Add in the sweetener. Mix until whipped cream forms.

This little cake is is a great treat! Just the right size!
Marcie says
This was fantastic! Amazing texture. Next time I will try adding a little more sugar and cocoa, maybe a smidge less baking powder (I could taste it) and a pinch of salt. So good though!

Two servings mean i should double the macros ? Or the net carbs is including the two servings?
staysnatched says
One cake is 2 servings. If you eat the entire cake double the macros. You should also calculate your own macros for every dish you prepare. If you don't use the same exact branded ingredients I use, your macros will differ.

This lacked flavor and was very bitter. Threw it away after one bite.

Interesting, there are other positive reviews here, so it may not be for you.

Literally just finished the bacon Gouda Mac and cheese which was amazing and made this for dessert.. don’t think I’ll ever need to make anyone else’s recipes! Everything I’ve made so far is perfection. This was so easy to make and the best mug cake I’ve made so far (and I’ve tried a ton of different recipes)
staysnatched says
Yay! I'm so glad you enjoyed it.

You’re welcome! I’m glad you enjoyed it!
Dthomas says
Pretty good. I think my microwave is a different wattage so I had to microwave for closer to two minutes but after that it turned out good! I’m not keto I just needed fulfill a ~small~ sweet tooth craving with the staple baking things I had so this was a great alternative for baking a whole dessert.
staysnatched says
Wonderful! I'm so glad you enjoyed it.
Jessica says
This was delicious and easy! I was excited to try it and made the mistake of mixing my ingredients before I fully read the post (rookie mistake!), so I didn’t oil my bowl. Luckily it turned out fine and didn’t stick too bad. I cooked it for 55 seconds and it was the perfect texture. My fiancé said he’d like it a little sweeter, so I might add a little more sweetener next time, but I thought it was very good nonetheless. I will definitely be making this again!
staysnatched says
I hope you make it again!
Les J says

Carissa says
Honestly, I thought a keto, one-minute mug cake would taste like trash but I should’ve known Brandi would never do that to me. This was delicious and easy as the title tells ya. I drizzled almond butter over it and 🤤🤤
Don’t sleep on her recipes!
staysnatched says
haha love it.
Krystal H says
I made this today and wow, it truly hit the spot. It satisfied my chocolate craving perfectly, minus the bad sugar and the guilt. I forgot all about half being the serving size and I inhaled the entire thing. I topped it with sugar free coconut whipped cream and a few strawberries. Absolutely delicious & I can't wait to make it again and drizzle choc-zero syrup on top!
staysnatched says
Wonderful! Glad you enjoyed it.
Felicia says
I tried a mug cake before made with tote in powder and vowed to never eat a mug cake again. But today I was craving something sweet. I looked at all the keto deserts snd saw this. Brandi has never let me down on a recipe so gave it a try. This was so good!!! It came together quickly and was moist and delicious. I diced up a strawberry to put on top. I also ate the entire thing. But it got my macros so it’s all good.
Thank you for this recipe.
staysnatched says
You're welcome! I'm glad you enjoyed it.
Amanda says
Can I substitute almond flour for regular flour ? I am allergic to tree nuts . Thanks
staysnatched says
I’ve never tried it. In general the two do not have a 1:1 substitution ratio. You can google the ratio to convert it.
