Easiest 3 Ingredient Cake Mix Mug Cakes (Gluten Free)

1 Microwave. Place the mug in the microwave & heat for 60 seconds. After 60 seconds, check for doneness using a toothpick inserted into the center of the mug cake. If it is not fully cooked, an easy way to avoid over cooking the mug cake is to reheat it in 5 second increments. 
2 Add toppings. Add toppings like frosting, sprinkles or chocolate chips & enjoy!
