 1 cup brown sugar
 1 cup butter or margarine, softened 
 1 cup flour
 1 tsp. cinnamon
 1 apple, cut up or cored, per serving
 Whipped topping or ice  cream
 
Combine sugars, butter, flour and cinnamon.  Mix until crumbly. Store mixture, which is enough for 8-10 servings, in the refrig. and use as needed.
For a single serving, place a cut up apple in microwave-safe cup or bowl and sprinkle 2-4 tbl's of the mixture on top; cover with plastic wrap and microwave on high until done, about 1-2 minutes.  Remove wrap and top with whipped topping.
