Well, you can either make them whole or you can cut them up & nuke them. Just get a bowl with a lid -- a glass bowl -- put your cored apple in it, a titch of water, load the middle with alternating layers of butter & brown sugar, put the lid on & nuke. How long? Depends on the apple size & the microwave strength & just how soft you want your apple to be. I'd say begin with 3 minutes & check & then add as you feel needed; you can check it as often as you like. For cut apples, I peel, cut & sprinkle with water, brown sugar & plop some butter in there on top, put the lid on & nuke for 1 minute & check.
You can also take them (either whole apple or cut pieces) out when done & pop them in an oven or toaster oven on broil for a couple minutes to kind of "brown them up" if that is your desire. You need to leave the lid off for that part.

Oh, on those apples --- I don't use cinnamon on them but put it on if you do like them that way. I like to pour some milk in them after their done & eat with a spoon. YUM!
