Creamy Chocolate-Banana Pie

Directions

1. 1

   On a floured surface, roll dough to a 1/8-in.-thick circle; transfer to a 9-in. pie plate. Trim crust to 1/2 in. beyond rim of plate; flute edge. Refrigerate 30 minutes. Preheat oven to 425°.
2. 2

   Line crust with a double thickness of foil. Fill with pie weights, dried beans or uncooked rice. Bake on a lower oven rack until edges are golden brown, 20-25 minutes. Remove foil and weights; bake until bottom is golden brown, about 4 minutes. Cool on a wire rack.
3. 3

   Meanwhile, in the top of a double boiler or a metal bowl over simmering water, mix 2/3 cup sugar, flour and gelatin. Whisk in half-and-half and egg yolks; cook, whisking constantly, until temperature reaches 160° and mixture is thick enough to coat a metal spoon. Remove from heat; whisk in sour cream and extracts. Transfer 3/4 cup mixture to a small bowl; stir in melted chocolate until blended. Refrigerate both mixtures until set but not firm, about 30 minutes.
4. 4

   Spread chocolate mixture evenly over crust. Fold bananas into nonchocolate mixture; spread over chocolate layer. Refrigerate until firm, about 2 hours.
5. 5

   Beat cream until it begins to thicken. Add remaining sugar; beat until stiff peaks form. Spread over top; if desired, sprinkle with shaved chocolate.
