This treat is for all chocolate and coffee lovers. So why not have a cup of mocha and make a 2-minute cake? If you avoid caffeine, I included a caffeine-free option made from chicory root. I also listed some allergy free options for those who can't eat eggs or nuts and added tips for oven baking. For more mug cakes, check out more keto recipes.

Too "eggy"? Although I like this combination, some of you may perceive it as too "eggy". You can try the following: use one egg, double all the dry ingredients and add 1/4 cup coconut milk, almond milk or cream. This mixture will make 2 mug cakes. Instead of the listed sweeteners, you can try other healthy low-carb sweeteners from this list. The reason I'm using both Erythritol and stevia is to mask the aftertaste some of the sweeteners may have.

Allergy-free Tips:

Egg-free version: Use 2 tbsp chia seed meal (16 g / 0.6 oz) instead of 1 egg + 1/4 cup coconut milk or heavy whipping cream + 1 tsp psyllium husk powder.

Nut-free version: Use 1 heaping tablespoon of coconut flour instead of 2 tablespoons of almond flour. If you don't have coconut flour, you can use 2 tablespoons of finely shredded desiccated coconut instead.

A fun way to learn about healthy low-carb eating!

  3. When done, you can optionally top the mug cake with whipped cream or creamed coconut milk.
    Tips for cooking in the oven: If you don't have a microwave, I suggest you make 4-8 servings at once. Preheat the oven to 175 °C/ 350 °F and cook for about 12-15 minutes or until cooked in the centre. Mocha Keto Mug Cake Enjoy! Mocha Keto Mug Cake

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Hit with the 22 daughter .


Just made this and added a little cinnamon just because. It's amazing. Mug cakes are always terrible, but this one is actually great!! Thank tou so much.


Thank you Wendy! 😊


Hi Martina.
Could I use flaxseed meal instead of eggs?  And if sone, what would be the measurements?  Also I just combine everything and heat it up in the microwave and it just hardens into a cake?  


Yer you can use "flax eggs" or "chia egg". I believe that for each egg you have to use a tablespoon of flax or chia + 3 tablespoons of water. Leave it to soak for about 10 minutes and then use instead of the egg. The mug cake will not rise as much as with eggs but it will still work quite well.


Hi Martina, I just made your vanilla keto mug cake and absolutely loved it!
I was wondering if I should use cocoa or cacao in this recipe. The ingredient list says to use cocoa, but it links to a cacao product on Amazon.
Please let me know when you get chance 😊


Hi Leigh-Anne, the link is accurate - I just use both interchangeably - it's the one that doesn't have any sugar or other ingredients in it 😊


OMG looks so good. Thank you for an easy recipe. I will make it tonight.


Thank you so much, hope you like it 😊
