Adapted from an apple crisp recipe at: http://en.petitchef.com/recipes/microwave-apple-crisp-for-one-fid-1139313
1/2 cup cherries, pitted
2 Tbsp brown sugar
2 Tbsp quick-cooking oats
1 Tbsp flour
1 Tbsp butter, melted
1 Tbsp white sugar
Place cherries in a mug. Toss with white sugar. Combine remaining dry ingredients in a separate bowl, until well mix. Stir in melted butter and pour over spiced apples.
Cook in microwave on high 2 - 3 minutes. Let it rest for a few minutes and the topping will get crispy.
