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 just made this dessert and it is fabulous. I love the fact that you can make it in under ten minutes from start to finish. I topped it off with homemade whipped cream and fed it to my husband. He loves it. Thanks again for another yummy dessert.
Penelope
This looks divine!!!!!! I found this recipe on Pinterest and I HAVE to try it! A few questions though, 1) what kind of dish should I use to bake it ? 2) could I use another citrus, such as lime or orange?
Brenda
I used a 7 ounce ramekin. Yes another citrus is fine.
Afrocat
Just had it, life saver after carb cravings. Thanks for your great recipes.
Natasha
Can you give me the measurements for using another sweetener. I am not a fan of Stevie and use something that measures cup for cup with sugar. Thanks
KaD
Liquid lemon stevia- really? I wish just once I could look at one of these recipes and NOT have to order some obscure ingredient off the internet.
Brenda
Are you not sugar free? These are regular products in my recipes, liquid stevia mostly. What do you use for a sugar free sweetener? You could certainly use what you have on hand.

I tried this today and was very pleased with the results. I did not have the lemon stevia and so used regular liquid stevia and added a bit of lemon extract. I also added a bit of lemon zest. I topped it with whipped cream sweetened with Gentle Sweet and it was divine! I ate the whole thing but honestly, it would easily have made 2 servings. Thanks so much!
I am new to mug cakes and what a great concept as so many times when I make desserts, I am eating them for days because my husband and family prefers sugar desserts. This is great!
Kate
This lemon mug cake is delicious. Thank you so much for the recipe.
shirley higgins
could I replace the cream with coconut cream? and if I want to bake it - how long?
Brenda
You can. 350 degrees for 15 min-20min, check in center with toothpick.
Toni Pierce
What could I use instead of lemon flavored Stevia? I don't use any flavored Stevias. Thanks
Brenda
You can use plain stevia that will be fine.
Leta Libby
I absolutely love the beautiful pictures you provide of your creations. They are so appealing. So glad to have found you on facebook,.
Brenda
Thanks so much!
Nicole
I made this with gluten free flour instead of coconut I used honey instead of stevia and almond milk instead of the heavy cream I really liked it but I like lemon and the tart of lemon bars this was very similar and next time I will add fresh blueberries in there YUM
Sunelle
These look delicious!
I would love to make my little boy one but he has an egg allerggy. Any suggestions on a substitute?
Brenda
Maybe a flax egg? Sorry I've not tried it without the egg.
Cheryl
I made it tonight and it was bitter. Odd after taste. I used liquid lemon stevia sweetleaf just like the instructions said and I couldnt finish it. I loved the texture and concept but am new to going sugar free. I've cut sugar out completely from my diet. So I wanted to try a couple of treats now that I've been without sugar altogether for a few months now. Is it just something you get used to or should I tweak it a different way.
Brenda
If it was bitter, you probably needed more than I suggested in the recipe. I've been sugar free for 12 years so I don't taste any bitterness when using stevia. It just might be you need to add more or try another sugar free sweetener like this one:https://www.sugarfreemom.com/recipes/what-is-erythritol-a-swerve-give-away/

Hello! My microwave does not work. Do you know if this would work to bake in the oven? Let me know. thanks 🙂
Brenda
I think you could bake it at 350 F for 15 minutes, but i've not tried it so keep an eye on it.
Sara
This recipe is magnificent. I made one tonight as I was craving a snack and I wanted something a bit sweet. It was absolutely perfect!
Lori Meislin Foster
My husband is a lemon fanatic. I surprised him with this tonight and he loves it. Thank you for another great recipe.
Brenda
So happy he liked it!
Reshel
This was fabulous! I never comment on these things but I had to let you know it was truly delicious 🙂 thank you for sharing .I will be using this often!
Debby
Way too sweet for me! Did I read it right? 1/2 teaspoon liquid lemon stevia? I'm going to try it again with a lot less stevia because it is very moist light and easy! Thanks!
Brenda
depends on which brand of liquid stevia you have. If you are using NuNaturals, it's much sweeter in comaparison to Sweetleaf.
Katie
Just found this and it looks delicious!
joanna
i am enjoying this cake right now and it is the BEST MUG CAKE EVER!! it is SUPER moist and decadent. i made a cream cheese frosting and added lemon zest to it. thank you so much. this is now my go-to afternoon snack!
joanna
oh and i also used a 1/2 packet of powdered stevia since i dont have any liquid.
Brenda
Thank you so much!
Jaie
This is delicious! Very lemony, light & fluffy. I will be saving this one for sure.
Sally
I don't use microwaves anymore, can they be baked in a convection oven?
Ashley Winkler
Can I make this cake without the liquid lemon stevia? I have THM sweet blend and wondered if that would work. I can't wait to try this ca,e!!
Brenda
I'm sure you could but I don't use THM blend so not sure how much you should use.
