Delicious grain-free lemony mug cakes bursting with blueberries. These easy low carb cakes are nut free and dairy free too. Keto coconut flour recipe.
This one goes out to my nut-free and dairy-free friends. I don’t often make things without nuts or dairy so you should feel very, very special! These days, food intolerances seem so prevalent and I am sensitive to the fact that having to restrict your diet in more ways than one would be exceedingly difficult. You turn to low carb for weight loss or other health reasons and then you find that practically everything low carb is made with something you can’t eat! And although I write All Day I Dream About Food with my own dietary preferences in mind, I realize that a lot of people turn to me for low carb, gluten-free recipes and meal ideas. I feel something of a responsibility to the low carb world at large, and every so often I try to create recipes that fit other dietary needs. As someone who seemingly doesn’t have any allergies or intolerances, I can only imagine how frustrating it is to restrict your diet in multiple ways.
So although I already have a low carb lemon mug cake recipe, made with meyer lemons, I decided it was high time to make another. This time, with coconut flour and and coconut oil in place of the almond flour and butter. These may seem like a few minor changes but if you’ve ever tried to sub coconut flour for almond flour, you know that it’s not the case. They are different beasts altogether and have to be treated very differently. Coconut flour isn’t as moist as almond flour, and requires far more eggs to rise properly. And if you add too much liquid to the batter, it becomes a soggy mess. So this really is a different recipe from start to finish. But it’s just as delicious! I love the juicy blueberries bursting through the tart lemon flavour.
We always keep a bag of the frozen wild blueberries from Wyman’s in our freezer. My husband loves them in his smoothies or just as a topping to Greek yogurt and we stock up every time we hit BJ’s. I prefer them for baking because they are smaller than cultivated blueberries, which means you get better berry distribution in your baked goods. I actually got a chance to meet some of the Wyman’s representatives at BlogHer Food a few weeks ago, and they have a very important initiative that I wanted to mention. You may have heard that honey bees are disappearing at an alarming rate. At this point, it is estimated that as many as one third of all honey bee colonies have disappeared. It’s not yet clear what the cause is, although it is highly linked to environmental changes. Wyman’s has been actively sponsoring and funding research and awareness initiatives for Colony Collapse Disorder, including a three year study on the impact of their own farms and facilities. Honey bees pollinate about one third of our nation’s produce, so it’s a problem we should all be taking very seriously. Read more about Wyman’s initiatives here.
Stepping off soapbox now. Wyman’s did not pay me or sponsor this post in any way, I just thought it was an important matter to discuss. And since we always keep their berries in our freezer and I used them for this recipe, it seemed like a good time! Enjoy the tasty mug cakes, they make a delicious breakfast or snack!

HI Carolyn,
Thanks you!!! Thank you so much for sharing your wonderful recipes… and for putting up with the occasional grumpy-gus. Please know that most of us love what you’re doing and appreciate you very much!!
This recipe looks like it would be just about the perfect size and portion to make large muffins. I do love a good blueberry muffin, and since these can be baked in the oven, that would definitely be an option.
I’m definitely gonna try this one! I can see it going oh so well with that morning cup of coffee… mmm, mmm, good! Do ya think it will be good for dunking?? 😀
Rachel says
Love the thought of blueberry lemon loaf! I baked this today using a suggestion made in previous comments. I thought I’d go all super star and double the recipe. I baked it at 350 for as long as it needed to get a fork in and out clean. It had great flavor before I baked it. Baking it at 350 was a terrible idea. Don’t know what happened but… it sucked. Bad. Bad enough to need to seish water in my mouth. Used high quality ingredients. Wish I could get them back!
Carolyn says
Coconut flour is very tricky stuff so sometimes it doesn’t multiply to more portions well.
Chelsea says
SOO yummy and moist! My husband made these for me for Mother’s Day. He added a few fresh raspberries and a drizzle of leftover coconut milk on the top to keep it dairy free. We now make these for all of you Gluten-Free or Ketogenic diet friends.
Jolene says
DELICIOUS! I only made one this morning out of the batch and LOVED IT! I hope I can just save the batter in the fridge to make one everyone morning until it’s gone. Thank you so much for sharing!
Carol W says
I subbed a packet of Trulemonade for the lemon zest, used fresh blueberries, half and half for the liquid.
I made frosting: ~3 oz cream cheese, stevita, 1/2 packet Trulemonade, lemon flavoring.
So delish! I am going to do a low carb cranberry orange version of this. Thanks! Your blog makes it so easy!
Scarlette says
Would it be possible to replace the coconut oil, or maybe half of it, with applesauce? Or maybe replace it with Greek yogurt? This recipe looks amazing, but there are a lot of calories in the oil/butter. I am cutting carbs AND counting calories right now. Thanks!
Janie says
EXCELLENT!!!! I also poured some cream over the top. Very very good!!!! 😀
Carolyn says
So glad you liked it!
samantha says
i just made these, left out the lemon extract and vanilla extract and added fresh lemon juice and vanilla stevia drops, then i doubled the recipe and added unflavored whey to the mix and put them in muffin tins for a quick breakfast on the go! my picky hubby LOVED them and so did i! i drizzled sweet cream on top also 🙂
Beth Novak says
Carolyn, I’m always trying to get my protein. Could I add some protein (whey) powder to these, do you think? This recipe looks amazing, as usual!
Lorrie says
I only have Stevia Glycerite. Can I substitute this for the Stevia Extract?
Thanks and keep the great recipes coming!
Carolyn says
Sure.
T says
what other flour can I use instead of coconut flour. I don’t have any and need to make this for a my sis who has bad heart and low sodium or no sodium?,
Carolyn says
Sorry, this recipe is coconut flour-based and hard to adapt. But you could use this one for almond flour and just add blueberries: https://alldayidreamaboutfood.com/2013/03/meyer-lemon-mug-cake-low-carb-and-gluten-free.html
Dani says
Made these but used silicone muffin thingys in the oven at 350 for ~15 minutes.
The recipe filled 13 muffin thingys. Great tasting but can’t wait to get some Swerve to cut my net carbs down from the Truvia I had to use.
Dani says
Just calculated that using Truvia BB – the net carbs were 6.3g/muffin (when making 13 smallish muffins from the listed recipe). Pretty awesome!! thanks.
Eileen says
I am not an egg lover. Finally a low carb breakfast that is delicious and satisfying! These are fabulous and so easy. Thanks!
Eileen says
If I only want 1 cake today is it best to microwave them all and refrigerate or to refrigerate the batter and bake fresh each day?
Carolyn says
I find they don’t rise that well if you bake them after refrigerating the batter.
jay stockhall says
I don’t use a microwave. Any idea if this would work in an oven? And if so, what temp and for how long?
Carolyn says
Try 350F and it’s going to take at least 10 to 15 minutes.
Karen says
Have you ever tried doubling or tripling the recipe and baking in a muffing tin? Then they could be frozen and warmed in a jiffy.
Carolyn says
No, but I am sure it would be good!
scilla b says
I only have coconut sugar to sweeten this, and dried blueberries, crossing my fingers that it works cuz it looks great!
Carolyn says
That should work really well, actually! The coconut sugar will give it a darker colour, just FYI.
Robyn says
Can you use honey, maple syrup, or coconut sugar in place of the other sweeteners?
Carolyn says
Sure, that should work.
Wenchypoo says
Colony collapse Disorder is caused by…MONSANTO! All their herbicide chemicals (Roundup, etc.), combined with their GMO strains of crops, are the root cause.
Carolyn says
Definitely part of it…I am moving more and more to organic foods and home-grown, non-GMO produce myself.
Mayren says
I would love to try this recipe. I just have one question, should I grease the ramekins with oil or butter?
Carolyn says
I don’t find that it’s necessary with mug cakes, because you’re eating them right out of the mug and not trying to turn them out onto anything.
Carole says
I sometimes like to turn out my mug cakes onto a small plate. If they a sticking slightly just run a knife around the sides and they will come right out. Can’t wait to try these, love lemon and blueberries together!
