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.

I recently came across this recipe and tried it. Usually, when I try recipes that call for cocoa powder, the end result is disgusting for some reason. This one did not disappoint, but I will say if you prefer it sweeter you may want to add more sweetener, depending on the kind you used.
I used Erythritol and it tasted more like barely sweet dark chocolate cake to me. I made it a second time and used 3 tbsp of erythritol and it tasted sweeter. If you prefer a slightly less chocolately taste, you may want to consider cutting back on the cocoa powder, but I also don’t know what that would do to the recipe. I also forgot to add baking powder, but it didn’t ruin the recipe (as far as I know).
tl;dr add more sweetener to get a less bitter chocolate taste, otherwise it’s perfect

Hi just want to know, if the almond flour can be replaced with all purpose flour. Thanks！
Christel Oerum says
You can, but then it’s not low carb and no longer a keto mug cake. If you do, you might need to reduce the flour slightly or add more fats/liquid for the cake to be moist
Is this intended to be 3 tsp of butter (aka 1 tbsp), or 3 tbsp?
Christel Oerum says
Yes, 3 tsp or 1 tbsp (we changed it to 1 tbsp in the text to make it clearer)

From a practical perspective, Truvia should be fine, it’s more if you like the taste of it in the quantities used (2 TBSP).
