As long as the steam can escape as they cook, apples will not explode in the microwave and that can be done by scoring through the skin. Cut deeply into the skin around the center of some medium cooking apples, then core and place in a deep, microwave-safe dish, in batches of up to four. You can also fill the centers with sugar or fruit filling then add a few tablespoons of water or apple juice to the dish.
Cover with microwave-safe plastic wrap and ensure that it does not touch the apples. Then pull back one edge to vent. Cook the apples on High for 4-6 minutes or until they are tender but retain their shape. Before serving, let them stand for 2-3 minutes.
