If you are low carb simply swap out the maple syrup for Lankanto Monkfruit. This mug cake is 12 carbs with the chocolate chips and only 4 if you leave out the chocolate chips!

I topped mine with the frosting included in the recipe and a few extra Enjoy Life chocolate chips, very yummy. My husband is not gluten or dairy-free and he liked it too!
