What is a mug cake?
A mug cake is a single-serve cake that is prepared and made in a mug. It is cooked in the microwave to can be cooked in the air fryer. You can even make single-serve cheesecake mug cakes.
Mug Cakes are also perfect for special occasions like birthdays when you want a little treat but don't want a full-sized low-carb cake.
There's a lot to like about this easy keto cake, but I find it to be a particularly helpful tool for those transitioning to a keto or low carb lifestyle.
Mug cakes, particularly this keto chocolate mug cake, are the perfect treat to help satisfy cravings for sugar.
As you go through your low-carb journey, you will continue to cut out more and more sugar. The strength of your sweet tooth cravings will depend on where you are on your journey.
So it's always good to have a few quick and easy sugar-free dessert recipes that will satisfy that craving while keeping you on track.
How do you make a chocolate mug cake from scratch?
To make the batter for your mug cake you will first need to melt the butter and cream cheese together in the microwave for 20 seconds.
Next, mix the remaining ingredients into the butter and cream cheese using a fork. Be sure to scrape the sides and bottom of the mug to ensure it is mixed well.
Gently tap the mug on the counter a few times to level the batter in the mug. Now you are ready to cook your mug cake.
Melt cream cheese and butter in mug. Mix in the rest of the ingredients. Stir together to make batter.
Do you need a microwave?
Yes you need a microwave if you want to cook your mug cake in 1-minute. You can however cook mug cakes in the oven, but then they are called muffins because you can't bake them in a mug.
Place your mug cake in the microwave and cook the mug cake for 1 minute on high. Cook times can vary a little depending on your elevation or microwave strength so check your mug cake after 1 minute to see if it is done.
Test the cake by inserting a toothpick or knife into the center of the cake. If it comes out clean the cake is done.
If your cake needs a little longer to cook pop it back in the microwave for 20-second increments until the cake is done. My microwave is pretty strong so it only took 1 minute for my cake to cook.
How to cook mug cakes without a microwave?
If you do not have a microwave or don't like to use them you can still make this mug cake. Rather than use the microwave, you can bake your individual mug cake in the oven using a cupcake pan or oven-safe ramekin.
Cooking the cake this way will take a little bit of extra time, but not much. Bake the cake at 180C/350F in the oven for 12 minutes, or until it is done. You can check for doneness the same way you would a regular cake - insert a toothpick into the center and pull it out. If the toothpick is clean, your cake is ready!

Air fryer
To cook mug cakes in the air fryer you need to find a small baking dish or ramekin to fit inside your air fryer. There must be at least 1 inch on all sides to allow the heat to circulate evenly.
- Preheat your air fryer to 180C/350F.
- Place the butter in your small baking dish and heat for 30 seconds to 1 minute, or until completely melted.
- Make the mug cake following the recipe card below.
- Gently lower your baking dish onto the air fryer wire rack. Ensure there is plenty of space between the ramekin dish and the side of the basket.
- Cook for 10 minutes, depending on the size of your air fryer and the size of your ramekin or small baking dish.

How to serve?
Once the baby cake is cooked, that's it! You can now enjoy a delicious quick and easy double chocolate cake for your birthday, special occasion, or whenever your sweet tooth hits.
To make your mug cake look extra special remove the cake from the mug and serve it on a plate topped with whipped cream. Most commercial whipped creams are full of sugar and carbs, so I suggest you make a keto-friendly whipped cream using your favorite low-carb sweetener.
If you really want to elevate this chocolate keto mug cake, you can even sprinkle on a few chocolate chips. Enjoy!

For the mug cakes, vanilla or chocolate, can the coconut flour be substituted with almond flour?
Libby Jenkinson
No, unfirty=unately coconut flour and almond flour behave in completely different ways. You can read the full guide on how to use coconut flour and almond flour here. I do however have an almond flour mug cake, that is the best way to use a recipe that has already been developed using almond flour rather than making lots of substitutions to the original recipe. It may now work out properly.

Could I underbake this and make it a molten cake?
Libby Jenkinson
I'm sure that would be amazing (as long as you don't mind raw eggs, which I don't). You could even pop a few sugar-free choc chips in the center too to make the chocolate mug cake extra gooey.

Can you leave out the chocolate chips? 🙂
Libby www.ditchthecarbs.com
Absolutely! You may also use cacao nibs if you can't find good sugar-free chocolate chips that have acceptable sweeteners.
