Oreo cookies are a great addition to cheesecake, whether you use them in the crust or chop them up and mix them into the batter. The crisp, chocolaty cookies are a nice textural contrast to the creamy cream cheese base of the cake, and the creme filling of the cookie blends in smoothly and sweetly to the rest of the dessert. I like them in any kind of cheesecake, but when I saw the Halloween Oreos – with their bright orange centers – on the shelves, I knew that they would make a fabulous Halloween-themed cheesecake.
