Ah cake! Who doesn’t love to enjoy a delicious cake? But this particular recipe is Keto friendly – hooray! I truly believe that in order to stick to a diet, we need to incorporate some treats into that, allowing us to reward our hard work and avoid crashing out of it when those hunger pangs strike. But the icing on this cake is that it takes about 5 minutes to prepare so you can be enjoying this little guy in no time at all and because it’s a mug cake, it’s just the right size for one (no temptation to have that second slice). 

This cake is gluten free (but you must check the cocoa powder that you use as not all cocoa powder is gluten free). Alternatively, you could replace the cocoa powder with vanilla instead.

Because you cook it in the microwave, the cake is not only quick but you can also devour it hot, straight away, no waiting – perfect!

I found this recipe when searching out treats for a keto diet. Of course, I decided to try it with Matcha (no surprises there) and I think it works beautifully. You gain all the health benefits of Matcha such as a sustained energy boost, focus and loads of antioxidants and also get to enjoy cake – it’s a win-win! It’s also natural for our bodies to crave something sweet when the weather is colder and the days are shorter and as this recipe uses coconut flour, it is also much lower in carbs compared to a wheat flour cake, so a healthier version of something yummy.

I think that this is a perfect recipe for an extra energy boost pre-gym, swim or just whenever you need that extra little something. It also uses just 6 ingredients, so what are you waiting for?


  • 1 tablespoon of coconut butter
  • 1 tablespoon of coconut flour
  • 1 teaspoon of Matcha
  • 2 tablespoons erythritol
  • 1 tablespoon of cocoa powder
  • 1 Egg


  1. In a pan melt the coconut butter
  2. Add the coconut flour, Matcha, erythritol and cocoa powder
  3. Add a beaten egg
  4. Mix well
  5. Pour into mug
  6. Microwave on high for 60 seconds
  7. Enjoy!

Mix up the recipe: you can make whatever flavour cake you fancy, we like a little bit of chocolate and think it works well with the Matcha, but vanilla is also well worth a try. Or you could try a chocolate orange cake by adding some orange essence, the possibilities are endless.
