Measure out and prepare all of the ingredients.

Mix together the cake ingredients into a mug. Stir together until you get a smooth consistency.

In a bowl, combine the ingredients for the glaze. Place in the microwave for 25 seconds. Mix together well so there are no clumps in the glaze.

Add half of the glaze mixture into the cake mug and use a toothpick to swirl the icing into the batter. Place the cake into the microwave for 60 seconds. You should be able to see the cake rise in the mug. Give it more time if needed or pull it out early, as every microwave is different. Just keep an eye on it. Remove and set aside.

Place the icing mixture in the microwave for 15 seconds. Stir this together and make sure everything is all melted. If not, microwave it in increments of 5 seconds until everything is melted.

Get the cake out of your mug by scraping the sides with a knife and tapping it out over a plate.

Pour the glaze over the top of the cake, then take the icing and pour that over the cake.

Serve and enjoy!
