Having this sugar-free lemon cake mix on-hand to make low carb lemon mug cakes in the morning is a game-changer! Save time by having your ingredients together beforehand. Fast and easy to make, you won't believe the incredible moist texture this mix produces.
I'm always looking for ways to streamline the morning routine. Getting the kids ready for school can easily become hectic if I'm feeling tired and my mind is not firing on all cylinders. Invariably, the first question out of my daughter's mouth in the morning is, "Mom, what's for breakfast?"
Some days it's challenging to find two brain cells to rub together to even think about making breakfast. On those days I like to make low carb mug cakes, or what some people call mug muffins, or mug cakes. We have been enjoying low carb chocolate mug cakes at breakfast for a few years now.
I pre-mix all of the ingredients for a sugar-free chocolate cake mix and then keep it in the pantry. I just measure my ingredients, add an egg and a little coconut milk, stir and pop it in the microwave. Breakfast is ready in under two minutes. It's a no-brainer when I have no brain!
Having a big batch of low carb lemon mug cake mix comes in handy for more than breakfast. I have been known to slice a minute muffin horizontally and use it as sandwich bread (no, not this lemon cake version - the chocolate one). It has saved me on the occasion I have forgotten to make gluten-free bread or just refuse to pay the price for another loaf of Udi.
I've also used it as a snack in the kids lunch boxes when I find we're out of fruit or traditional snacks. And it's a pretty healthy alternative to regular breads, cakes and muffins because it has some fiber, some protein, some healthy fats, and is very low in sugar. Well, then I go and spoil it by putting jam on it.
These low carb lemon mug cakes are really yummy. My mom was so impressed with the light, tender texture that she asked me if there was anything weird in them. By weird she meant any alternative ingredients. Well, yeah... Low carb and gluten-free baking equals weird ingredients sometimes and sometimes weird results, but not with the recipe.
This sugar-free lemon cake recipe uses an important ingredient to get that burst of lemon flavor- Real Lemon packets. It's crystallized lemon juice. I often use it when I need a lemon flavor and don't have fresh lemons in the house. It was perfect in this lemon mug cake. Because the lemon is already in the mix, you won't have to fool with cutting and squeezing fresh lemons in the morning. The acid in the Real Lemon crystals contributes to such an amazing texture. You'll swear you were eating cake.
If you follow a low carb diet and are looking for a new minute muffin recipe or are just looking for a quick low carb breakfast option, it couldn't get any easier or tastier than this recipe. For a great Paleo chocolate mug cake recipe, try this one from WholesomeYum.

Low Carb Lemon Mug Cake (Sugar-free Lemon Cake)
Ingredients
Lemon Minute Muffin Master Mix
- 4 cups Almond Flour
- ⅔ cup Coconut Flour
- ½ cup whey protein powder (I like Isopure zero carb)
- 1 ½ cups erythritol
- 1 tablespoon baking powder
- 1 teaspoon baking soda
- zest from two lemons (completely dried)
- ½ teaspoon salt
- 12 packets True Lemon
To Make A Muffin
- ½ cup Lemon Minute Muffin Master Mix
- 1 large egg
- 1-2 tablespoon full fat coconut milk (or heavy cream or oil)
Instructions
For the Mix:
- Zest two lemons and leave the zest on a plate to dry all day.
- Measure all of the ingredients into a large bowl. Stir with a whisk to break up any lumps and to evenly distribute all ingredients.
- Put the Lemon Minute Muffin Master Mix into an air tight container. When the zest is dry, crumble it with your fingers and add it to the mix.
For the Muffin:
- Measure ½ cup of mix into a large mug or a bowl. Add the egg and coconut milk or oil and mix until all of the dry ingredients are completely incorporated. Let the mug or bowl sit on the counter for a minute to activate the acid in the dried lemon juice.
- Cook your minute muffin for a minute or more. Mine takes one minute and twenty seconds. You'll be surprised how much this is like cake!
- Each muffin serves 2 and the nutritional information is for 1 serving or ½ of a muffin.

Hi, Kim. Can I make this with sucralose and if so, should I use the same amount?
Kim Hardesty
Hi Jane. Try the same amount and taste to see if you need more. -Kim
Jenny
Hi Kim! I found this recipe after loving your chocolate mug cake. I have two questions on this one - could I use egg white powder in place of the whey isolate to be dairy free? Also, would this recipe benefit from the use of mayo similar to the chocolate one? Thanks for your help. I love all the small serving desserts.
Kim Hardesty
Hi Jenny. I have never tried using egg white powder in lieu of protein powder so I can't answer that. I am currently in the middle of preparing my house for an out of state move and can't test that for you. I won't be able to do any testing for a month or two. Sorry about that. -Kim
Ron
Do you happen to have a batch recipe for chocolate?
LOW CARB CHOCOLATE MUG CAKE MIX (SUGAR-FREE LEMON CAKE MIX)
Kim Hardesty
Hi Ron, no I don't BUT if you use the recipe scaler and it will scale it up for you. Just make sure to make a single portion of ingredients first, so that you know how much to measure when making an individual cake. -Kim
Ronald
Kim thank you for the quick response. I will give it a try,
Vicky
Changing the servings to 2
how do I measure .08 coconut flour and .06 protein powder?
Is the protein powder necessary? If not should I substitute something ?
Kim
Hi Vicky, I see the problem. I didn't know that the recipe scaling function did that. The person who wrote the recipe card is in Europe and is not familiar with our measuring system in America. Let me give you some information to help you. I am in Costa Rica right now and not connected with some of my programs.....
3 teaspoons = 1 tablespoon
4 tablespoons = 1/4 cup
5 1/2 tablspoons (16 1/2 teaspoons) = 1/3 cup
I hope this helps you figure out a smaller portion size. I will connect with the program developer to see if we can fix this problem. Thank you for bringing it to my attention. -Kim
Kim
Oops! I forgot to answer your other question. The protein powder gives the mug cake a very nice texture. You can try subbing some coconut flour. -Kim
Vanessa
Hi there! What is the shelf life of this mix? Will it also work if I use pre-dried lemon peel like McCormix makes?
Kim
Hi Vanessa. The mix will keep in the fridge indefinitely. The pre-dried lemon peel is not very good in this recipe. -Kim
Suzanne
OMG! So yummy, easy, and quick! This is a keeper!
Stephanie
Thank you - it's delicious!
Lisa
Oh yeah! This is delicious! Gotta go. Can't type and eat. One is clearly more important right now.
Janey
Mmmm!
Beverly
I love the opportunity to make the chocolate, lemon mug cakes but sorry to say I do not understand the ingredient amounts as written. For example:
0.08 cup Coconut Flour
0.06 cup whey protein powder
0.19 cups erythritol
0.13 tablespoon baking powder
0.13 teaspoon baking soda
0.06 teaspoon salt
0.06 cup Lemon Minute Muffin Master Mix
0.13-0.25 tablespoon
I read carefully your conversion chart. Am I to 'tar' the scale with a cup and weigh .08 coconut flour, for example?
The same for a tablespoon and then a teaspoon? That seems awkward.
Please explain. Thank you,
Beverly
Kim
Hi Beverly, you must be talking about scaling the recipe which is a feature when clicking the up/down arrow on the recipe servings. I have never used the scaler, so I wasn't sure of what you were speaking at first. How many servings are you trying to scale it back to and maybe I can help. -Kim
Beverly
two servings - but the amounts are either strange or I do not know how to read them.
thank you for helping
Kim
It's not you, Beverly, I'm not sure why the recipe scales that way. It's very weird! Maybe it's because the program developer is European and used to metric. In any case, I can get you down to 4 servings. Just divide the amount in half to make a large muffin and follow the instructions, or divide the mix into quarters and mix with 1 egg yolk one time and the next time the egg white so that you don't end up wasting ingredients. Does that make sense?
1 cup almond flour
3 Tbsp coconut flour
2 Tbsp protein powder
1 tsp baking powder
1/4 tsp baking soda
zest from 1/2 lemon
pinch salt
3 packets Tru Lemon
Beverly
Thank you for understanding my puzzle about amounts.
I will use your amounts - can't wait for the lemon - my favorite.
Yolie
Kim, just wanted to say that you have great recipes!! love them, and especially they are all low carb! thank you so much for all of them!!
Kim
That is so nice, Yolie. Thank you so much. -Kim
Mary Jo Stamper
Totally addicted to this...do you have any other master mix recipes? So convenient!
Kim
I love this, too, Mary. Thanks so much for commenting. This recipe was not popular so I didn't share any of my other mix recipes. I had a chocolate one, too. -Kim
Meredith
Hi there - any chance you could provide the ingredients for just 1 serving, seems a little rough to divide everything by 16. Thanks!
Kim
Hi Meridith, hover over the serving size and choose how many servings you need. The recipe program will calculate it for you. I suggest choosing 2 servings and cutting the muffin in half as I intended. -Kim

Need I say more?! Yes! I love them! So why don't I marry them, you may be thinking. Well, I'm already married. But if my husband kicks it before me...

Thanks Wendy (or should I say Buddy?). That movie rocks. Thanks again and have a wonderful weekend. -Kim
Sarah C
My son is a Starbucks Lemon Loaf fanatic and ever since going Low Carb has missed it terribly - until now. He says "it's not EXACTLY the same but it's pretty close!" I love it too and don't feel bad letting him have his "lemon cake" now.
Kim
Sarah, I'm so glad your son has an acceptable Lemon Loaf replacement. Starbucks has had some hits over the years! Thanks so much for taking the time to leave a message. Have a wonderful weekend. -Kim
Pan
Hi there! I'd love the recipe for the chocolate cake master mix you mention here. I see the chocolate muffin master mix recipe, but not the cake. Thanks!
Kim
Hi Pan. I haven't made than in a long time because I am always working on new recipes. I will look for the recipe and give it a whirl in the next week or so. Thanks for your comment! -Kim
Wendy
Okay, it's been over a week or so. Did you do the chocolate muffin mix yet? A girl's gotta have her chocolate!
Kim
Oh, actually Wendy, I did one for Sukrin USA. The recipe is on their site. It uses peanut flour and cocoa powder and is really nice - just like a nice light cake. Check it out and see what you think. There are actually two recipes: one for a peanut butter mug cake and one for a chocolate mug cake. You can always double and triple the ingredients to get more servings. Let me know if those recipes don't interest you.
Wendy
Hmmm... I'm not finding either recipe there. Am I search challenged? Help!
Kim
Sure Wendy. I forgot to tell you that they were on the Sukrin USA blog. Here's the link: http://sukrinusa.com/guest-post-peanut-flour-mug-cake/
Wendy
Ha! I did a search on your site and found it! They won't keep me from my chocolate! Uh, I mean, the recipe looks lovely and I do enjoy chocolate. Ahem.
Kim
Haha! I'm glad you found it Wendy. I hope you like them. If you were looking for something different, let me know! -Kim
Angela
Where do you buy the packets of true lemon? And if I wanted to use real fresh squeezed lemon juice, how much?
Thank you
Kim
Hi Angela. I used to buy True Lemon in the grocery store but now buy from netrition.com. I specifically used the dried lemon juice so that this could be kept as a mix and one would only have to add coconut milk and an egg. I haven't tried it with fresh lemon juice but suggest trying 2 teaspoons - 1 tablespoon per muffin. I'd be interested to hear how it goes. Will you post back if you try it and how much lemon juice you thought was right? It may help someone else...
Incidentally, I use the packets to make my kids lemonade without the mess and sometimes add a packet to my water or use it to 'brighten" a recipe if I am out of lemons. Thanks for your question. Have a great week. -Kim
Cyndi
theres a reference to a master mix (non lemon) but I can't find it. Do you have a link to it?
Kim
Hi Cindy, are you speaking about the chocolate mix I mention in the post? I haven't written a post about it nor taken photos, yet. But if you are interested, I will get working on it. Let me know. - Kim
Michelle @ Modern Acupuncture
Beautiful photos! I love the ease of having the mix pre-made. What a great idea! Especially for mornings when I'm in a rush and don't know what to have for breakfast. Where did you get that gorgeous turquoise mug?
Kim
Thanks, Michelle! Any time-saver is alright in my book! I LOVE that mug. I got it at Home Goods. Thanks for visiting.
