Just in case anyone doesn't know the it's the spoon. You shouldn't put metal in a microwave it causes sparks and can lead to fires.
The obvious solution is to not put the spoon in the microwave. If you really don't want to remove the spoon from the bowl for some reason (werid), they do make wooden spoons for eating with. Korean wooden spoons. Easy to find on Amazon if you are interested.
But... Honestly it can't be the spoon. You shouldn't put a spoon alone in the microwave. But when it's in a liquid it actually helps disperse the heat better. It doesn't spark, I'm not even shitting you. I do this.
