A chocolate mug cake is the laziest dessert that you can make to get that sweet tooth under control. In less than 5 minutes you get a spongy chocolate cake.

This mug cake trend has its pros and cons. I’m not a fan of believing that a mug cake is the exact same thing as a regular baked cake.
But I must admit that it comes handy when your niece wants something sweet and there is no time — or willingness — to bake an entire chocolate cake.
For me, mug cakes —- like my vanilla mug cake — are exceptionally good as a single serving cake. Sometimes I don’t want to make an entire cake just for me. In those cases, mug cakes are the answer.
Also, I must say that the convenience of this type of cake is unbeatable. I mean, you can get it done really quickly and only using a mug. Zero dirty bowls, mixers, and spatulas. A mug and a spoon, that’s it!

How to make a chocolate mug cake?
As I’ve said before, this is an extremely easy recipe.
The first thing is to get a 12 to 16-ounce (350 to 475-mL) mug — I used this super cute fox mug that I completely love.
Then, melt the butter in the microwave for 5 sec. Be careful because the butter can splatter easily in the microwave.
Then, add the egg and sugar and mix really well.
Next, add the milk. Slowly incorporate the flour with the baking powder. Mix gently to avoid powder flying everywhere. Finally, add the cocoa powder and, again, mix carefully.
I prefer to use a fork to mix instead of a spoon. It makes the process a lot easier. With a spoon, you can get part of the flour or the cocoa powder stuck to the inside of the spoon.
After you get a nice batter without clumps, it’s time to “bake”.
Just take your mug to the microwave for 1 minute 30-sec setting you microwave to 800 W.
Every microwave is a bit different, so the key is to start at 1 minute and see how the cake is doing. Then increase the time for 10 seconds until you get all the cake done. It’s better to undercook and then add a bit of extra time than to get a dry and overcooked cake.
It’s normal that the cake has a semi-undercooked finish when you take it out of the microwave. It will dry up a little when it cools down.
Yes, this is a bit of trial and error because not every microwave works the same, unfortunately.
