For the crust:
Preheat oven to 350.

chocolate and butter in small saucepan over low heat. Cool. Beat
eggs and sugar in medium bowl until slowly dissolving ribbon forms
when beater are lifted, about 4 minutes. Beat in melted chocolate
mixture, vanilla, and chopped chocolate. Add flour and baking
powder. Mix until just blended--do not overbeat. Spread 1 cup
brownie batter over bottom of pan. Bake until firm, about 17 minutes.
Cool baked crust in freezer for about 15 minutes. Maintain oven
temperature.
For the filling:
Blend cream cheese and sugar until smooth. Add eggs and sour cream.
Add peanut butter and flour. Using small knife, spread remaining
brownie batter around the sides of the pan, sealing batter to bottom
crust. Pour in filling, which will not be as high as brownie batter.
Bake until center of cheesecake is gently set and brownie sides have
fallen to form a ring around the filling. (About 50 minutes)
For topping:
Blend sour cream and sugar. Spread on top of cheesecake to within 3/4
inch of edge. Bake cheesecake 3 more minutes.
