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!

It’s also the perfect base for fun and tasty toppings. So go ahead and add keto-approved chocolate chips, nuts, or sugar-free syrups.

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. 

3. Keto Chocolate Mug Cake

Looking to get your chocolate fix without making a whole cake? Then this is the perfect recipe for you.

Soft, fudgy, and decadent, this chocolate cake hits the spot every time. It’s the ideal recipe for any keto chocolate lover. 

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.

Vanilla cake with tart blueberries is a dream in a cup. So the next time you get a fresh batch of berries, make this yummy cake!

9. Keto Coconut Mug Cake

Coconut cake is naturally sweet and oh-so-flavorful. It’s basically an island vacay in a mug!

Calling for only seven simple ingredients and two minutes of prep, it’s full of coconut flavor and topped with coconut cream for a boost of sweet moisture.

If you love coconut, this will be your new go-to cravings crusher. 

10. Almond Flour Mug Cake

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!

Or are they?

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.

It’s loaded with fresh orange zest (or oil) along with dark chocolate for the most delightful contrast of flavors.

If you’re a fan of Terry’s Chocolate Orange, you’ll love this one.

13. Keto Pumpkin Mug Cake

The next time you get a craving for a sugar-filled pumpkin spice latte, try this simple mug cake instead.

Warm spices and tasty pumpkin are a match made in fall heaven. And this cake is super moist and fluffy.

Top it off with whipped coconut cream and sugar-free caramel, and it might even be better than the infamous PSL!

14. Keto Oreo Mug Cake

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!).

When they’re done, you’ll add a thick layer of cream filling in the middle and make a big Oreo-like sandwich.

It may not have the signature crunch, but it’s the best keto alternative you’ll find!

15. Low-Carb Keto Banana Bread Mug Cake

Got a few extra ripe bananas lying around? Then you can make this yummy banana bread mug cake!

It’s soft, sweet, and just what you’d expect from a slice of warm banana bread.

It’s also way easier to make, and in a single-serve, so you don’t have to worry about those leftovers calling your name.

Plus, there’s chocolate! Need I say more?

16. Keto Spice Mug Cake

If you want a mug cake that’s not overly sweet but still super satisfying, this spice cake is terrific!

It has the perfect balance of warmth and sweetness, is incredibly fluffy, and only takes a few minutes to make. 

Add a dollop of whipped cream for a delicious finishing touch and some sweet contrast.

17. Keto Funfetti Mug Cake

Funfetti cake is one of my favorites, and this colorful concoction is ideal for a ketoer’s birthday.

With only 5.8 net carbs, it would work as a yummy birthday breakfast or mid-day sweet treat.

Vanilla and shredded coconut give the almond flour base extra pizazz. Top it off with more sprinkles, and get ready to sing!

18. Keto Carrot Cake in a Mug

Carrot cake is incredibly moist and moreish, and this keto mug cake is no exception. 

It has a lovely blend of spices and a dreamy cream cheese frosting to boot. Ready in minutes, it makes a great snack or dessert any day of the year. 

19. Keto Red Velvet Mug Cake

This keto twist on the classic red velvet does not disappoint.

It makes a spectacular treat at Christmas or for Valentine’s day. But after one bite, you’ll crave it all year long. 

Plus, the tangy and sweet cream cheese frosting is, well, the icing on the cake!

20. Keto Gingerbread Mug Cake​​

You have to try this cake even if gingerbread isn’t your go-to. 

It’s packed with warm and tasty spices, and it’s incredibly soft and moist. The flavor is spectacular, and the simple icing really makes it pop. 

I can’t believe this cake is keto-friendly, and you won’t, either.
