Sugar Free Lemon Mug Cake made low carb, keto, nut free, gluten free, and a single serving for perfect portion control! Just 3 net carbs!
Sugar Free Lemon Mug Cake
This easy lemon mug cake is perfect for when you just want a single serving and not have any left overs in the house. It's gluten free, grain free, tree nut free and absolutely lemony!
If you live in New England or any place that has had frigid temperatures and a whole lot of snow over the last couple of months, you can be certain we are all ready for the spring season!
I am a lemon lover truth be told. Love them in my water, seltzer and in recipes as much as possible like this Sugar-Free Frozen Lemonade, this Strawberry Lemon Sorbet, and these delicious No Bake Lemon Cheesecake bars!
Spring time for me means lots of fresh produce and ingredients. The aromatic smell of lemons remind me of spring no matter what season it is. They're just so fresh; I always feel rejuvenated when I can get my daily whiff.
I have even been known to ingest the juice of an entire lemon as a shot to help cure a sore throat. Might sound harsh, but I can tell you it works better than anything I've ever tried.
I've made this recipe 4 times before posting it. I am always looking for the perfect and moistest first bite. I tried with different combinations of coconut four, one time with some flax seed, then 2 eggs, then more lemon, but finally what I'm sharing is the best combination.
Not too much lemon, just enough. Perfectly soft in texture. And I can honestly say even if you are not a coconut fan you'll love this. My littlest man hates all things coconut and loved this cake! The coconut is not noticeable at all, the lemon is the star, I promise!
How to Make Sugar Free Lemon Mug Cake
Ingredients
You just need a few easy ingredients to make this sugar free lemon mug cake. Egg, lemon juice, low carb sweetener, heavy cream or see below for a dairy free option, coconut flour, baking powder and salt.
Directions
Whisk the egg, lemon juice, cream and stevia together in a small bowl.
Stir in the coconut flour, baking powder and salt.
Pour batter evenly into two 7 ounce ramekins.
Microwave 1 minute and in 30 second intervals for each or until toothpick in center comes out clean.
Top with sugar free whipped cream if desired!
Coconut Is Not a Tree Nut
I'd like to clear up this constant question get asked almost daily about whether coconut is a nut. While the US Food & drug Administration (FDA) claims that coconut is a tree nut becomes it comes from a tree, it is in fact a FRUIT.
People who have tree nut allergies may be allergic to coconut as well, but being allergic to coconut is not the same as having a tree nut allergy.
My own son was diagnosed with a Peanut and Tree Nut allergy at the age of 2. He has safely eaten coconut all these years without issue and he is now 14. Coconut is a fruit, called a drupe. It's like a peach with a pit.
The American College of Allergy, Asthma and Immunology says it well: "Coconut is not a botanical nut: it is classified as a fruit, even though the FDA recognizes coconut as a tree nut. While allergic reactions to coconut have been documented, most people who are allergic to tree nuts can safely eat coconut. If you are allergic to tree nuts, talk to your allergist before adding coconut to your diet."

I *have* to make this Today. I don't have a microwave. How long would I bake it in a 350(?) oven?
Brenda
I would guess just 15 minutes then check in center with a toothpick.
DonnaT
I'm so glad Monica asked ..and you answered.. I'm so wanting to try this (and will tonight), but I don't use my microwave. Aafter seeing a demonstration of two plants, treated exactly the same except one was watered with tap water and the other with microwaved (then cooled, of course) water. Will never forget the picture of that poor plant that got the microwaved water. So, now I can very happily make this as suggested, in the oven.
ananimous
Don't have any heavy cream on hand right now, anything else I could use?
Brenda
I'm sure it would still be tasty using milk or even coconut cream from the can.
Ressa
This looks heavenly what if I don't have liquid lemon stevia?
Brenda
Use any sweetener you like.
Celsey
Is there any way to make this in larger version?
Corrie
I'm making this now!
Rose | The Clean Dish
Delicious!! Short list of ingredients = my kind of recipe 😉 I'm thinking breakfast tomorrow morning!! I love that you can use coconut cream instead of regular cream.
Kim Beaulieu
I am a serious lemon lover so this one is right up my alley. I think it's that time of year where we're so over winter, all of us are craving citrus, hoping it jump starts spring. I can't wait for sunshine.
Kirsten/ComfortablyDomestic
There is nothing more cheery than lemon in everything at the end of a long winter. I've never made a mug cake before, but this one looks divine!
Kelsey @ Snacking Squirrel
the prettiest mug cake i have ever laid eyes on!
Nancy P.@thebittersideofsweet
I am definitely a lemon lover! And you can't beat 4 minutes with a dessert!
Lauren @ Healthy Delicious
I'm so over winter and am more than ready for all things lemon! This cake looks really tasty. I think I'll ty it for dessert tonight!
Jean
I just had to make this right away after I saw this recipe. Love anything lemon. So disappointed that I did not have any coconut flour left after I had the other ingredients, so I used spelt flour and it turned out great. I liked it a lot. Since I never made it with coconut flour, I cannot vouch for that. But will definitely make this often and next time I have coconut flour, will make it that way too.
Brenda
Thanks for sharing your substitute!

I'm a huge lemon fan. As I write this, I'm sipping on my warm lemon water. It's a great way to start the day. Your lemon mug cake looks so pretty. I love the light yellow color. Plus it looks incredibly light in texture too. A winner for sure. Pinning!
Ginny McMeans
Why thank you! I am a lemon lover too. I have never made a mug cake and this one looks like a great way to bring in the spring.

Can I use lemon juice instead of lemon extract in this ?
Cat
I'm sorry I thought I was still on the lemon pound cake. So my question should be posted on that page please.
The Food Hunter
Such a nice shade of lemon 🙂
Sarah
I Love your recipes! my only comment/request is that you include fiber! esp since you are sugar free, it is important to know how much fiber is in there to subtract from the carbs if you carb count. thank you!
Brenda
Hi Sarah, not sure why you mention it because every single recipe has nutrition info and fiber is included in all of my recipes. I also all ready wrote the net carbs in the notes of the recipe.
awillburn
I'm allergic to egg. Can I use a flax egg instead?
Brenda
I don't see why not although I've not tried it. If you do, please come back and let me know how it was.
Ann
Do you know if this is gluten free? Thank You
Ashley @ Wishes & Dishes

Cookin Canuck
I am a lemon lover, through and through, though have never tried that cure for a sore throat. I'll have to try that one! This mug cake looks like the perfect dessert for springtime.
gail
I am allergic to coconut.Is there another flour that would work in this recipe?
Mel Doogan
Any gluten free flour would work.
mom2one
Could sunflower seed flour work? Allergic to nuts and have to avoid coconut flour while on low fodmap diet. 🙁
Joan Marion
Garbanza Bean Flour or Almond Flour would work and remain low carb and higher protein 🙂
Stephanie @ Back for Seconds
I am a huge lemon lover and this looks completely dreamy, Brenda!
Lora @cakeduchess
