This delicious fall-inspired keto apple mug cake evokes cozy sweaters and sitting by the fire with a good book and your favorite socks on! Loaded with shredded apples, walnuts and caramel – you can go from craving to eating in just minutes!
My deep and abiding love of keto mug cake recipes goes way back! I’m talking years here. And what’s not to like? They are easy to make, have built in portion control, and you can go from craving to noshing in literally minutes.
Best invention ever.
It’s been awhile since I posted a new keto mug cake recipe, so I decided to come up with one that would celebrate fall and apple season. Thus this Keto Caramel Apple Mug Cake recipe was born – and it’s a another winner if I do say so!
On it’s own, it’s humble and warm and cakey and apple-ey in the most perfect way ever – essentially comfort in a mug of fall flavor that evokes cozy sweaters and fluffy scarves and sitting in the warm glow of a fire with your favorite socks on.
It’s a lot to get out of a bite of keto apple cake that you made in your microwave in less than five minutes. But there it is.
Of course it’s only made better by some keto vanilla ice cream, a drizzle of sugar free caramel and some chopped walnuts.
Even Hungry Jr. was a big fan of this keto apple mug cake – so much so that it was the first thing he told Mr. Hungry about when he walked in the door that evening.
“Dad, mom made this awesome apple caramel cake thing IN THE MICROWAVE. Then she put ice cream and MORE caramel on it and it was SO GOOD. You HAVE to try it!”
That’s a seriously resounding endorsement for an 8 year old – and I’ll be honest, I was totally flattered since my little foodie is hard to impress these days.
Now if only I could get him that excited about broccoli and cauliflower.
Whether you’ve been on the fence about keto mug cakes or you’re an addict like me, you definitely need to get out your favorite mug and fill it with this low carb caramel apple mug cake STAT. It’s equally fantastic with or without the ice cream and toppings – pinky promise.
Keto Apple Mug Cake Recipe Notes:
To make this apple mug cake recipe Paleo just replace the sweeter with honey or maple syrup and increase the coconut flour to 2 tablespoons to make up for the extra liquid.
For snack sized portions, instead of a mug you can divide this batter among 4 paper baking cups and cook them for one minute – then an additional 15 seconds as necessary depending on the strength of your microwave until they are slightly firm.

I’ve experimented with lots of low carb mug cake flavors over the years, and not surprisingly the most popular keto mug cake recipe here on IBIH is the Chocolate Brownie Mug Cake – it’s pretty amazing, so if you haven’t made it yet add it to your list ASAP!
I don’t have a microwave. Can this be done in the oven?
This cake is SO GOOD! I will say the apple flavor really did not come through like I’d hoped, and this was very much a caramel cake in my experience, but absolutely delicious, none the less. I subbed Torani Sugar Free Salted Caramel syrup for the extract, and it worked very well, but maybe that’s why I lost the apple flavor. Will definitely be making this again, thanks Mellissa for all of the excellent recipes, it is truly appreciated!
I’ve been meaning to compliment you on your recipes for some time now,
especially the ones containing lemon! They are so good; you are talented.
The link above for the caramel extract shows a product that contains
sugar (Watkins Caramel Extract). Has it changed or where do I find one
without sugar. It seems like caramel flavor is particularly challenging
for foodmakers. Thanks and we wish you continued success!

I can’t believe it took me 3 years to find this recipe! As in ALL your recipes, this one knocked it out of the ball park! It was absolute heaven. I had some homemade cinnamon ice cream in my freezer and I used two large ramekins to make the cakes. I had to put one in the fridge for tomorrow or I would have eaten both of them right away, Thank you once again for another fabulous and easy keto dessert!
This was amazing!! My son loved it too. Thanks so much.
I don’t diet by net carbs, I diet by total carbs. How would I go about determining the total carbs in your recipes?
I just have to say how thankful I am to have your menu plan! I am a busy working mom that finds it difficult to plan out my meals and days. I usually end up getting whatever is fastest for lunch while I’m working. Which is why I have still not lost my baby weight. I’ve been on your plan for 5 days and have lost seven pounds!! I’m so glad to have structure and delicious food and start to feel really good about myself!!
I am deathly allergic to almonds. What can I use instead for the almond flour?
Mellissa Sevigny says
In a recipe like this you can’t just sub something else without changing everything so unfortunately this probably isn’t the recipe for you. If you search nut free mug cakes on google you might find some though!
Jessica @ eatwelloutsidethebox.com says
I am so going to have to make this right now!!! Only I don’t have almond milk on hand so coconut milk will have to do:)
This was yummy! I only had Maple Extract and it must have been an acceptable substitution because the four if us thought it was delicious with low carb ice cream on top. We used Bryers.. My 8 and 13 year olds asked me to make it again tonight.
You are a genius! I didn’t have ice cream so used low carb whipped topping. Still delicious! What brand of low carb ice cream do you recommend?
Amy S says
Thank you for all of the hard work and resources you put into developing these recipes. Which low-carb vanilla ice cream did you use? A commercial brand or a recipe of your own?
Quick and amazing treat!
