20 Low Carb Keto Mug Cake Recipes
1. Keto Vanilla Mug Cake
Moist, light, and deliciously simple, this fluffy vanilla mug cake is a thing of beauty.
The vanilla flavor shines in every bite, and the sponge is insanely tender. Better yet, it has only two and a half net carbs!

2. Keto Snickerdoodle Mug Cake
Get ready for a cinnamon flavor bomb because this snickerdoodle mug cake is heavenly.
It isn’t just low-carb – with only four net carbs per serving – it’s also gluten- and dairy-free.
Don’t let that scare you, though! Full of flavor, it’s fluffy, moist, and oh-so-satisfying!
Almond flour gives this cake its incredible texture and a lightly nutty finish. You’ll love every spoonful.

4. Keto Cinnamon Roll Mug Cake
Your favorite sweet breakfast just got a keto makeover! This cinnamon roll mug cake is warm, gooey, and way too good to miss.
Packed with warm spice, the sponge is delightfully light and airy. And there’s ever a super indulgent cream cheese glaze on top.
At just four net carbs, you’ll be shocked at how tasty this mug cake is.
5. Keto Lemon Mug Cake
Lemon cake is a wonderfully bright, sweet, and tart dessert. And just because you’re on keto doesn’t mean you can’t indulge too!
Full of zesty lemon flavor, you’ll add cream cheese to the batter, ensuring every bite is rich, moist, and flavorful.
If you have sugar-free powdered sugar, make a quick glaze with lemon juice to boost the zippy flavor.
Without a glaze, though, it’s three net carbs.
6. Keto Peanut Butter Mug Cake
With loads of peanut butter flavor, this mug cake will satisfy any craving.
Peanut butter is naturally low in carbs, and if you buy the right kind, it’s sugar-free too!
Mix it with some coconut flour, sweetener, cream, and baking powder, and you’ve got one tasty cake (with just 3.6 net carbs!).
The chocolate chips are optional, but they add a nice hit of gooey bitterness.
7. Keto Strawberry Mug Cake
Strawberry mug cakes are a delightful treat full of sweet, fruity flavor.
Soft and moist with just the right amount of sweetness, you’ll use real strawberries for the best flavor and color.
And with only 4.4 net carbs, this fruity dessert can be enjoyed any time the mood strikes.
Just keep in mind: strawberries are very juicy, and when they bake, those juices have nowhere to go but in the cake.
With that in mind, you’ll want to cut the strawberries quite small and not add too many. It’ll be dense and chewy if you get too much juice in the batter.
8. Keto Blueberry Mug Cake
With all those fresh and fruity blueberries, this keto cake can be enjoyed for breakfast or dessert.
It’s fluffy and light, kind of like a muffin, and the berries add such beautiful pops of color, too.

Almond flour is used a lot in keto baking because it makes cakes nice and tender, adds a bit of sweet, nutty flavor, and is gluten-free to boot.
Plus, almonds bring extra protein to the mix, so you can feel good about every bite.
This simple cake has about six net carbs, which means you can indulge without hesitation.
11. Keto Caramel Apple Mug Cake
Caramel apples are a fall fave in my house. But they’re not the most keto-friendly treat in the world!

Between the shredded apples, crunchy walnuts, and caramel flavor, this cake has all that sweet, fruity goodness in one mug!
It’s rich, inviting, and unbelievably keto-approved.
So cozy up with a warm cup of caramel apple cake and let your winter worries melt away!
12. Orange and Chocolate Chip Keto Mug Cake
Low in carbs and sugar, with only 6.3 net carbs per serving, this bright and zesty orange cake is such a fantastic twist on the usual mug cake recipes.

Calling all Oreo lovers! This fluffy, delicious, and low-carb cake is the best way to enjoy your favorite cookie while doing keto.
Unlike the other recipes on this list, you’ll make two mug cakes, and they’re a little bit thinner than usual (so be careful when microwaving them!).
