Apple Upside-Down Cake

Caramelized apples and walnuts atop a tender butter cake are a fabulous combination, and bourbon whipped cream is the perfect accompaniment to balance the sweetness of the caramel. This cake is most delicious in the fall at the height of apple season and is much quicker to make than a conventional apple pie. Use baking apples that hold their shape well: My favorites are Macoun, Northern Spy, Rhode Island Greenings, and Golden Delicious.
