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!

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 this is so good! I used 4 tbsp almond flour and 1 1/2 tbsp coconut flour. I added Lilly’s sugar free chocolate chips to the top halfway between cooking. It DID turn out pretty dry, but tasted delicious! I’m the kind of girl that loves dry brownie mix out of the box so I loved it this way. I had it with a scoop of carb smart ice cream. I never gain on Leto this way. Thank you! Best mug cake recipe yet. Without substituting the coconut flour for some of the almond flour it probably wouldn’t have been as dry but I LOVE it like that!
My 9 year old and I love this! Thank you, Katie! I appreciate having recipes that help my sugar free kiddo not miss out!
THIS IS NOT KETO!!!
I imported the recipe into my fitness pal and the total carbohydrate is 24.6g and fibre is 6g. The net carbs is 18.6g.
For all of you saying it is too good to be true, it is. I made it for my mum on the keto diet and feel awful for breaking her diet. 7
Hi Christine, it looks like either the calorie counter you used is inaccurate or it isn’t removing the erythritol carbs from net carbs (they are not included in net carbs). What specific ingredients did you put into the counter? It sounds like just a computer error 🙂
It’s only 8 net carbs if you use the keto sweeteners.
This was so delicious for an easy keto dessert thank you!!
This mug cake is amazing! It’s so simple and I already had the ingredients in my cabinets. I will definitely use this as my go to.
This made us so happy 🙂
This is great! I actually made half the recipe in a small ramekin and it was plenty. I keep my sugar down to under 5g per serving so using 5g of semi-sweet chocolate chips does the trick. Still 1 min in the microwave then let it cook a few minutes and it was real cake 🙂
Such a delicious keto cake recipe!
This mug cake recipe did not call for any oil or butter. Was that an omission? All of the other mug cake recipes on this web site call for oil or butter. Please respond.
Nope, no need! This one is made with almond flour so already has fat from that.
So good!! Satisfies the cravings for sure!
The only modifications I made were I did not add the cocoa powder, I don’t have any. I used heavy whipping cream as the milk and I add about a tablespoon of strawberry cream cheese. Zapped in the microwave in 30 second intervals and I added Lilys dark chocolate sugar free chips before cooking another 15 seconds (2 times at 15 seconds)
It tastes like a warmed up chocolate chip 🍪 HEAVEN 🙌🏾
Your version sounds even better!
This looks so delicious. I can’t wait to try it.
