Tips for making a moist and fudgy keto mug cake
It is key to keep an eye on your mug cake as it cooks in the microwave. Every microwave is different and will cook at various temperatures. Keep an eye out for when the cake has risen in the mug and is completely set. The cake will come out moist and fudgy with no effort at all!
When using cocoa powder and low-carb sweeteners, you must watch out for the bitterness that some sweeteners can bring out of the cocoa powder. I would not recommend using stevia in this recipe as it can make the mug cake taste more bitter. I find that xylitol or erythritol works well in this recipe.
Eat the cake right away!
You can store this mug cake in the fridge for a day or so if you absolutely want to, but there is really no point in doing it. Making a new one is almost as easy as re-heating one.
The cake will also set in the fridge and become denser and less fudgy so I highly recommend just eating it right away.
