18 Sweet Keto Mug Cakes

When you need a quick, easy dessert but you’re on a low carb diet, keto mug cakes are perfect to try. I’m sharing multiple mug cake recipes here!

Are you trying to lose weight on a ketogenic diet? Then, you probably know that you need to watch your calories as well.

After all, they say “Calories in, Calories out”. You can’t eat an entire cake every day and expect to lose weight, right?

And having an entire cake lying around is a recipe for disaster. Especially when you’re craving cake.

So, what do you do when you really want some cake? Have a keto mug cake!

Keto mug cakes are great for portion control. And they’re super convenient.

So, you can satisfy your cravings as soon as they start. Before they lead to giant cravings.

To help you, I’ve compiled a list of mug cakes. They’re delicious, but best of all convenient.

To make these treats, you’ll need to make sure you have microwave-safe mugs. Or, some ramekins as some recipes call for them. You can get a set of heavy-duty ramekins here.

1. Keto Chocolate Mug Cake

Chocolate Mug Cake


Do you dream of chocolate, chocolate, and more chocolate? Then try this keto chocolate mug cake.

It’s moist, and chocolatey, and has a nice crust on top. Just as if you baked it in the oven.

But you don’t. You just combine all your ingredients in a mug and microwave for 1 minute.

And out pops delicious gooey cake. You won’t believe it’s keto.

To make this cake keto, you use almond flour. Almond flour has way less net carbs than regular flour.

It also has more fat, making it perfect for a keto diet. If you plan to do a lot of keto baking now, or during the holidays, be sure to stock up on some here.

Top your chocolate mug cake with a strawberry and some fresh cream. And enjoy a cup of tea.

  • Protein: 11.3g


2. Low Carb Snickerdoodle

Snickerdoodle Mug Cake


Do you dream of Snickerdoodle cookies? Have this Snickerdoodle Mug Cake instead.

It’s much healthier for you. And since it has a whopping 27 grams of fat, it’s sure to keep you satiated … and away from any tempting Snickerdoodle cookies.

It’s also really cakey and fluffy. And has a nice cinnamon taste as the batter contains cinnamon, as does the topping.

To get that Snickerdoodle look and taste, you top it with granular erythritol sweetener. This is one of the best sweeteners on the market right now, and you can find it here.

  • Fats: 27g
  • Net Carbs: 4g

3. Vanilla Chocolate Chip

Chocolate Chip Keto Mug Cake


Are you getting tired of eating bacon and eggs for breakfast? Then give this mug cake a try.

After all, who said you can’t have cake for breakfast? Especially when it’s good for you.

This mug cake has a ton of fat and a pretty decent amount of protein. So, you’ll feel full and not be tempted by the muffins at work.

Plus, it contains dark chocolate chips. Dark chocolate contains tons of cancer-fighting antioxidants.

To keep it keto, do make sure you don’t use regular sweetened dark chocolate chips. They’re packed with sugar and tons of carbs. Use stevia-sweetened dark chocolate chips like this instead.

This keto mug cake is filled with chocolatey goodness and has the perfect texture for dunking. So dunk in some coffee or tea and enjoy the breakfast of champions.

Per Mug Cake:

  • Calories: 285

4. Lemon Mug Cake

Lemon Mug Cake


Do you like your desserts a bit more tart? Then, this lemon mug cake is a great option.

It’s crumbly and moist-just like “real” cake. And it’s bursting with lemon flavor.

While the sugary glaze provides a nice complement. It’s sure to satisfy your sweet tooth.

You’ll also like that it contains only 195 calories. So, it makes for a nice light snack.

To keep it keto, you’ll need coconut flour as well as almond flour. Coconut flour is another low-carb flour that you’ll want to have on hand, not only for baking but for making pancakes as well.

And since coconut flour absorbs liquids pretty well, you only need a bit. If you’d like to get some, you can find some here.

5. One Minute Chocolate Brownie

One Minute Chocolate Brownie


Do you find chocolate brownies addictive? I sure do.

You can’t stop at just one, or even two. Before you know it, you’ve gobbled a whole pan.

That’s why I love this one-minute chocolate brownie. You get to have your brownie fix guilt-free.

This brownie is simply decadent. Perfect for a nice date night.

This recipe does call for Sukrin Gold Fiber Syrup. It’s a syrup that is low in net carbs that you can find here.

If you don’t have any on hand, you can use Swerve instead, and add an egg to your batter.

Per Mug Cake:

  • Calories: 101
  • Fats: 6g

It’s yummy and has a nice firm texture. Perfect if you don’t like your chocolate cake gooey.

And it’s not too sweet. So, a nice low carb ice cream would be the perfect complement.

Do keep in mind that it’s pretty high in calories. So, if you’re counting calories, you may want to eat to split it with someone else.

Just like this keto mug cake, these sweet keto fat bombs are full of fat as well!

It contains enough protein and fat to keep you in ketosis. And it provides 16% of your daily fiber needs.

It’s also pretty delicious. Isn’t that a good enough excuse to have cake for breakfast?

Now, this mug cake is non-vegan. But, making it vegan is pretty easy- just replace the egg with a flax egg instead.

Birthday Cake in Minutes


Birthdays are a great excuse for some birthday cake. But, the leftovers can be pretty tempting.

Even more tempting when you are trying to lose weight. So, should you just skip the birthday cake entirely?

No! Have a birthday mug cake instead.

This two-layer vanilla cake is pretty yummy. Topped with a buttercream frosting, it’s great just the way it is.

To make the frosting, simply mix your softened butter, vanilla extract, almond milk, and some powdered sweetener.

I recommend Swerve sweetener because it doesn’t have the bitter aftertaste that some other sweeteners have.

To decorate the cake, top with some nice sugar-free chocolate chips. Or, just add some caramel sauce. Yum.
