Mix all cake ingredients in a small bowl. Spray the edges with nonstick cooking spray. For best results, mix ingredients in a separate bowl than you cook the cake in.
Microwave the cake for 45-60 seconds, watching for overflow. If the cake starts to bubble over, stop the microwave and cook it in 3-5 second intervals until finished. (If you're doubling the recipe, cook the cake for 90-120 seconds. Do not overcook.
Once the cake is finished, mixed your icing ingredients except for the sprinkles in a small bowl. Top the cake with the icing before adding the sprinkles. Dig in!
