In this version of apple crisp, prepared sugar cookie dough is used to create a chewy, crispy, sweet and all-but instant topping for the classic fall dessert. And there's plenty of room for improvisation here. If you like your crisps with large chunks of topping, skip the food processor and oats. Simply break off clumps of dough and scatter them over the apples (or pears or a blend). The cookie dough also could be adulterated with all manner of add-ins, from candy bits and chocolate chips to dried fruit or nuts. With the exception of nuts, add-ins are best mixed into the dough and oats after processing. For speed and ease, this recipe calls for prepared cookie dough (the sort found in the grocer's refrigerator case), but if you have the time homemade dough would taste even better. And when serving, don't forget the vanilla ice cream. After all, milk and cookies go so well together.
