Keto cake in a mug?

Yeah, I was skeptical too at first….

But Keto mug cakes are one of the fastest and easiest ways to make you own quick low carb snack or dessert.

Most recipes just involve mixing all the ingredients in the mug and then microwaving for a minute or so. Yep, it’s that fast!

And you’ll end up with a fluffy and delicious low carb cake in a mug. Flip the cake out onto a plate or just stick a spoon in and enjoy straight from the mug.

Plus, because they’re in a mug, you get smaller portions so you can avoid overeating (and sharing) as well.

Keto Chocolate Mug Cakes

Keto Chocolate Brownie Mug Cake Recipe

– Keto Summit

Keto Chocolate Brownie Mug Cake Recipe #keto

Ingredients: egg, almond flour, baking powder, vanilla extract, cacao powder, cinnamon powder, stevia, salt.

This keto mug cake can be a great way to introduce the benefits of cacao as compared to cocoa as it has many anti-oxidants, but a much more defined flavor. This recipe takes only a couple of minutes to make, giving you a quick and easy cake for unexpected guests or for a simple snack to keep you going through a busy day.

Ingredients: coconut oil, Sukrin Gold Fiber Syrup, vanilla extract, unsweetened cocoa powder, coconut flour, baking powder, heavy cream.

You know that feeling you get when only a brownie will do? Well here is the keto answer to that! A brownie that is rich and chocolatey, yet still low carb and delicious. It has a crumbly texture, but maintains a gooier centre so it even looks like a brownie. You can replace the fiber syrup with granular sweetener like Swerve plus one egg, as the fiber syrup contains malt.

Ingredients: butter, almond meal/flour, cocoa unsweetened, granulated sweetener of choice, egg, coconut flour, baking powder, vanilla.

Mug cakes can be very useful as a really quick and simple snack to have mid-afternoon, and are a great snack for kids! They can even be allowed to make their own (with supervision)! If you or your family don’t like cocoa, add in a little more almond flour and flavor it with lemon extract or you could just make them vanilla and top with fresh berries.

Chocolate Cake in a Mug (Contains Dairy)

– Ketovale

Ingredients: egg, salted butter, almond flour, coconut flour, unsweetened cocoa powder, Swerve or any keto sweetener, vanilla extract, baking powder, walnut chips (optional), sour cream (optional).

This recipe would be perfect if you are having a busy day and just need a chocolate hit but without the added carbs. The cake is spongy and delicious with a good chocolate flavor and comes as an individual serving to enjoy with your coffee. All microwaves are different, so if this is your first attempt, cook for two-thirds of the time and test the centre of the cake with a cocktail stick – if it comes out clean the cake is ready!

Super Easy Keto Chocolate Brownie Mug Cake (Contains Dairy)

– Low Carbs Park

Ingredients: butter, coconut flour, organic cocoa powder, egg, whipping cream, water or almond milk (optional), sweetener.

In this recipe, the egg and wet ingredients are absorbed by the coconut flour, so they don’t have an eggy flavor, but are still moist and squidgy in the middle. There is enough chocolate flavor to satisfy a choccy craving but still keeping an eye on the carbs. If you want to serve these on a plate, butter the inside of the mug and the cooked cake should slide out easily.

1 Minute Sugar-Free Chocolate Mug Cake (Contains Dairy)

– Sugar Free Mom

Ingredients: egg, unsweetened almond milk, liquid chocolate stevia or sweetener of choice, ground flaxseed or almond meal, unsweetened cocoa powder, baking powder, salt, coconut oil, water, whipped cream or dairy free whipped cream.

This recipe is for a microwave mug cake, but you also have the option to bake it in the oven if you don’t have a microwave. Adding the flaxseed meal will result in you getting a fluffier sponge cake consistency, but if you don’t have it don’t panic! You can use almond flour instead without affecting the texture too much. Like any new cake mix, it is better to taste it first before cooking so you can adjust the sweetness.

(No Sugar!) Flourless Keto Chocolate Chai Mug Cake

– Healthful Pursuit

Ingredients: cacao powder, epicure Poudre Douce, baking powder, egg, almond butter, chai tea, xylitol, stevia.

Here you get two different cakes from the same recipe, a spongy one and a fudgy one, so the choice is up to you! The only difference is one ingredient, so you can make whatever form your family prefers. You can also use water to replace the chai tea if you don’t have it, although you will miss out on the flavor. Serve these on their own or drizzle some melted chocolate over the top to finish it off.

Ingredients: butter, almond flour, coconut flour, granulated sugar substitute, vanilla, salt, egg, unsweetened cocoa powder, baking powder, 90% chocolate, pecans (optional).

Mug cakes are the best form of portion control and are ideal if you are only making the treat for one or two people. This one has a light and spongy texture with a fudgy center and is enough to satisfy any sweet craving. If you have a less powerful microwave you might need to adjust the cooking time and, like all brownie recipes, you are best to taste the mix before cooking to see if you need to adjust for sweetness.

Keto Mug Cakes With Fruit

Sugar-Free Lemon Mug Cake

– Sugar Free Mom

Ingredients: egg, lemon juice, heavy cream, lemon liquid stevia, coconut flour, baking powder, salt.

This is a great recipe to try if your family don’t do coconut too well, as the taste of the coconut is masked by the lemon so they won’t even notice it’s there! However, if you are dairy-free, you can swap the heavy cream for coconut cream for an even healthier snack. Lemon desserts are a great way to round off a family dinner on a lighter note – not only that, these take only minutes to make!

Strawberry Mug Cake (Contains Dairy)

– I Breathe I’m Hungry

Ingredients: butter, granulated sugar substitute, almond flour, coconut flour, egg, strawberries, baking powder, vanilla extract, salt, heavy whipping cream.

These mug cakes are so quick and easy that you could rustle some up in a matter of minutes! You can either use mugs or paper cases to cook them in and it doesn’t even matter if they turn out a bit on the ‘rustic’ side because you are going to top them with a dollop of cream topping and a slice of strawberry! Perfect for a party or as a gift for a friend!

Raspberry Cream Cheese Mug Cupcake (Contains Dairy)

– Modern Low Carb

Ingredients: butter, almond flour, egg, sugar substitute, vanilla extract, baking powder, almond extract, cream cheese, raspberries, salt.

If you have been looking for a low carb dessert or snack and have been disappointed, then try this recipe for a cupcake made in a cup! It has a buttery, spongy texture and has a fruity hit from the raspberries that is complemented by the creamy frosting. One important thing to remember is that microwaving or baking berries can leave them super-hot, so if these are for the youngsters, let them cool a bit first!

Keto Berry Mug Cake

– Keto Diet App

Ingredients: almond flour, coconut flour, baking soda, Erythritol or Swerve, egg, sugar-free vanilla extract, extra virgin coconut oil or butter, liquid stevia, berries (mixed, fresh or frozen).

If you are new to keto and are still missing bread, mug cakes can help you get past this stage as they give you the same sort of spongy texture as bread or cake, but without all the nasties! These cakes turn out beautifully and studded with berries which give fresh flavors and juiciness to the cake. These would be great for a fast breakfast, or top with coconut milk for a quick and easy dessert.

Keto Lemon Blueberry Mug Cake

– All Day I Dream About Food

Ingredients: coconut flour, Swerve, lemon, baking soda, salt, eggs, coconut oil, coconut milk, lemon extract, stevia extract, frozen wild blueberries.

These lemon and blueberry mug cakes are not only low-carb, they are also gluten-free, so ideal for family members who are gluten intolerant. They have wonderful hidden pockets of blueberry juiciness hidden in the sponge, which is light and fluffy. These cakes are quite filling, so use smaller coffee cups as your mug cake molds, especially if these are for children.

Other Keto Mug Cakes

Delicious Mug Cake (Contains Dairy)

– Keto Connect

Ingredients: almond flour, erythritol, egg, butter, sour cream, cinnamon, salt, vanilla, baking powder.

This is one of those recipes for a basic mug cake that you can take and play about with to find your favorites. It has a cinnamon topping which gives you a delicious cake to eat with your coffee, but you can play around with different flavor options if you prefer. If you don’t like sour cream, you can substitute it for crème fraiche instead, but you might need to add a little water.

Cinnamon Keto Mug Cake

– Keto Diet App

Ingredients: almond flour, coconut flour, ground cinnamon, baking soda, erythritol or swerve, egg, extra virgin coconut oil or butter, liquid stevia (optional), whipped cream or coconut cream, cinnamon (optional toppings).

The funny thing about cinnamon is that, although a cake may not have a lot of sweetener in it, the cinnamon seems to make it taste sweeter, which can come in handy if you are trying to avoid too much sweetness. It also gives the sponge a lovely speckled appearance once it is cooked, yet is a gentle flavor that goes really well with a cup of coffee. These also make a great idea for breakfast, especially on a busy day when you don’t have spare time.

Snickerdoodle Mug Cake

– All Day I Dream About Food

Ingredients: Swerve sweetener, ground cinnamon, almond flour, baking powder, cream of tartar, salt, egg, butter or avocado oil, water, vanilla extract.

The cinnamon in this mug cake gives a subtle warmth and turns it into aromatic comfort food. Just imagine tucking in to one of these with a hot cup of tea on a chilly day, or even using it to warm you for a delicious breakfast! The recipe calls for ingredients that most of us will already have at hand, so it doesn’t involve a special trip to the store, and can be ready to eat in a matter of a few minutes.

– Low Carb Yum

Ingredients: almond flour, coconut flour, baking powder, salt, coconut oil, almond milk, egg, Natvia, vanilla extract.

I often find with birthday cake that a lot of it goes to waste, especially if your kids are grown and have flown the nest! So I was delighted to find a recipe that tastes as special as a birthday cake, but is a more personal size. You can make whatever frosting you prefer to make this your own, but however you decorate it, you end up with a yellow spongy cake to satisfy your sweet tooth and help celebrate your big day!

Keto Cinnamon Roll in a Mug (Contains Dairy)

– Fit Mom Journey

Ingredients: almond flour, baking powder, cinnamon, Truvia, butter, egg, cream cheese.

Cinnamon rolls can be a lovely warming start to the day for a satisfying breakfast, or eaten as a snack mid-afternoon to keep you going till dinner, but either way, this recipe can fit your needs quickly, as they take just a couple of minutes to get ready. These have a strong cinnamon flavor, so feel free to tone it down if you prefer a hint of cinnamon instead.

Cinnamon Flax Seed Low Carb Muffin In A Mug

– Wholesome Yum

Ingredients: coconut flour, flaxseed meal, baking powder, sea salt, egg, coconut oil, erythritol, cinnamon.

With an elegant swirling of cinnamon, this muffin has a fantastic flavor which can be enjoyed for a healthy breakfast, or you can remove it from the mug, slice it and spread with your choice of butter instead of bread. This is another recipe that can help ease you away from eating bread like we used to, especially at breakfast time. Either enjoy this as it is or finish it off with a creamy topping.

Matcha Mug Cake (Contains Dairy)

– Everyday Maven

Ingredients: egg, pure vanilla extract, unsweetened non-dairy milk, matcha, monkfruit sweetener, butter, coconut flour, baking powder, ground sea salt.

Matcha is a green tea that is full of anti-oxidants and is very healthy, but one of the best things about using it in this recipe is that it turns the cake green! When my kids saw it they couldn’t wait to try it as they are obsessed with strong colors! If you leave the cake to rest for a couple of minutes, you will find the sides pull free from the mug, making it easier to remove.

Perfect Keto Collagen Mug Cake

– Perfect Keto

Ingredients: eggs, full fat coconut milk, nut butter, baking powder, Pink Himalayan salt, raw cacao powder, Perfect Keto Collagen, liquid stevia (optional), ghee (optional).

We all know the benefits of collagen in healing gut problems and looking after the health of our joints, skin and hair, but I was surprised that it could be put into a cake! This recipe results in a warming and satisfying cake in a mug that you can enjoy anytime from breakfast onward. If you find it a little dry on its own you can serve it with a little ghee over the top.

Low Carb Pumpkin Mug Cake

– My PCOS Kitchen

Ingredients: pumpkin puree, unsweetened almond butter, unsalted butter softened, egg, stevia powder, baking powder, cinnamon, ground cloves, nutmeg, ground cardamon.

Thanks to the pumpkin puree, this mug cake is slightly moister than some, but the overall flavor is delicious! These would be quick and satisfying treats to make near Thanksgiving, or as an alternative to a dessert, as the cinnamon, nutmeg and cloves give this cake a true pumpkin pie flavor. These cakes taste just as good served hot or cold.

Green Tea Mug Cake

– Keto Delivered

Ingredients: egg, green tea protein powder, almond flour, baking powder, erythritol, coconut milk.

Here is another quick and easy recipe that uses green tea as the main flavoring. As this flavor can be quite fresh, these are a good idea to make for breakfast, especially if you are short on time first thing in the morning. They can be sweetened to whatever level you prefer, and only take about a minute to cook. The calorific value of these is quite high, so don’t be tempted to over-indulge if you are watching your weight!
