Set aside to cool to lukewarm, then stir in the mini chocolate chips. Press into the bottom and up the sides of a buttered 9-inch pie plate. Chill for 30 minutes to set the chocolate.
Prepare the filling: In a large bowl with an electic mixer, beat the cream cheese until fluffy. Beat in the condensed milk, peanut butter, and vanilla.
In a meduim bowl, beat the heavy cream until soft peaks form. Fold the whipped cream into the peanut butter mixture. Pour the filling into the crust.
Make the topping: Melt the milk chocolate over hot, not simmering water. ( I use the microwave, but heat slowly and stir often}. Add the heavy cream and stir constantly until blended. Set aside to cool slightly, then drizzle the chocolate over the top of the pie. Refrigerate until firm, about 2 hours. Garnish with milk chocolate curls.
