Recipe by: Rebecca Oeswein <oeswein@dadd.ti.com> Preheat oven to 150ºC . In a large bowl, beat together cream cheese and sugar until light and fluffy, 2 to 3 minutes. Beat in eggs, one at a time. Add vanilla, beat until smooth. Add heavy cream, beat till well blended. Transfer one third of batter to another bowl and set aside. Beat melted chocolate into remaining batter. Pour into crust. With mixer on medium speed, beat peanut butter into remaining one third batter until thoroughly mixed. Carefully spoon peanut butter mixture on top of chocolate cheese mixture in pan. Using the long handle of a wooden spoon, swirl the two flavors together. Bake about 1 hour, or until cheesecake is set around edges and puffed but still jiggles slightly in the center. Let cake cool 2 hours, then refrigerate until well chilled, 8 hrs. or overnight. For a crust, I use Oreo cookie crumbs and make a crust using their recipe. I also do not swirl the flavors together. I like them layered better.
