Makes one 9-inch single-crust pie
This recipe is from "Bubby's Homemade Pies," by Ron Silver and Jen Bervin (Wiley, $29.95). The peanut butter pie has been a permanent feature on Bubby's menu since the eatery opened in 1990. A light peanut butter mousse is piled into a graham cracker crust lined with a layer of chocolate ganache (a rich spread of cream and chocolate) and chocolate shavings on top.
1 graham cracker crust or chocolate crumb crust
Never miss a local story.
Peanut butter mousse
1 cup confectioners' sugar
1 cup creamy peanut butter
3 ounces cream cheese, at room temperature
1 teaspoon vanilla extract
1½ cups heavy cream
6 ounces bittersweet chocolate
¾ cup heavy cream
2 tablespoons shaved
chocolate, to decorate the top
Use the paddle attachment of an electric mixer at medium, then high speed, to beat together the sugar, peanut butter, cream cheese and vanilla until they are light and fluffy. In a separate bowl, whip the cream until it holds good, stiff peaks. Place a few spoonfuls of whipped cream in the peanut butter mixture and mix on medium speed to combine evenly. Add the remaining whipped cream and fold it into the mousse on the slowest setting, until all the chunks are gone. Cover and refrigerate.
To make the ganache, melt the chocolate in the top of a double boiler over low heat and stir until smooth. Add the cream, stirring continuously, until completely combined. Spread a thick layer of ganache in the pie shell, covering the bottom and the sides of the crust as evenly as possible, using an offset spatula, spreading from the center outward and up the sides with arcing strokes. Chill the crust in the freezer until the ganache is set.
Set aside about ½ cup of mousse. Fill the pie with the remaining mousse, smoothing the top with a spatula. Use a pastry bag with a plain tip to pipe the reserved mousse into peanut butter kisses around the edge of the pie for decoration. Sprinkle the top of the pie with the shaved chocolate. Refrigerate the pie for at least two hours before serving. Store it in the refrigerator loosely covered for up to four days.
