When the fall weather turns cool this is my favorite pumpkin cheesecake, and makes an ideal choice for Halloween and Thanksgiving entertaining. The taste of pumpkin is mild with just a hint of warm spices, and the melted white chocolate adds a smooth sweetness and creaminess that is divine. The crunchy chocolate cookie crust supports the creamy cake, and is so easy to make when you just throw them into a food processor or small grinder. Top the cake with white chocolate curls and shavings to delight the eye as much as the palate.
