PIONEER WOMAN BOSTON CREAM PIE RECIPES

Steps:

• Preheat oven to 350 degrees. In a medium mixing bowl combine flour, sugar, baking powder, and salt. Make a well in the center of the flour mixture. Add milk, oil, egg yolks, and vanilla. Beat with an electric mixer on low to medium speed until combined. Beat an additional 3 minutes on high speed and set aside.
• In a large mixing bowl, beat egg whites and cream of tartar on medium to high speed until soft peaks form. Pour the egg yolk mixture over the egg white mixture and fold in. Gently pour the batter into a 9-inch greased pie pan. Bake for 25 to 30 minutes or until the top springs back when lightly touched. Invert the pan onto a wire rack. Cool completely.
• Pastry Cream Filling: In a medium saucepan, heat the milk and vanilla bean to a boil over medium heat. Immediately turn off the heat and set aside to infuse for 10 to 15 minutes. In a bowl, whisk the egg yolks and granulated sugar until light and fluffy. Add the cornstarch and whisk vigorously until no lumps remain. Whisk in 1/4 cup of the hot milk mixture until incorporated. Whisk in the remaining hot milk mixture, reserving the empty saucepan.
• Pour the mixture through a strainer back into the saucepan. Cook over medium-high heat, whisking constantly, until thickened and slowly boiling. Remove from the heat and stir in the butter. Let cool slightly. Cover with plastic wrap, lightly pressing the plastic against the surface to prevent a skin from forming. Chill at least 2 hours or until ready to serve. (The custard can be made up to 24 hours in advance. Refrigerate until 1 hour before using.)
• Ganache: In a medium bowl, pour the boiling cream over the chopped chocolate and stir until melted.
• To assemble pie, remove the cake from the pan. Cut the cake in half horizontally. Place bottom layer on a serving plate or board, and spread with the pastry cream. Top with second cake layer. Pour chocolate ganache over and down the sides of the cake. Store in refrigerator.

Steps:

• Prepare the pastry in a food processor, combine the walnuts and sugar and pulse until the nuts are finely ground. Add the flour and salt and pulse to incorporate. Add the butter and pulse until the mixture is the texture of coarse meal with pea size pieces. Add 2 tablespoons of ice water and pulse until the dough is evenly moistened. The dough should hold together when squeezed, but not be too wet. Add up to 2 more tablespoons of ice water, if necessary. Tip out the dough onto a piece of plastic wrap and using the plastic to gather the dough together, form it into a disk. Chill for at least 2 hours or up to 2 days. (Alternatively, you can freeze the dough for up to 1 week).
• Preheat oven to 375 degrees F. On a lightly floured surface, roll out the dough into a 12-inch-diameter round (about 1/8 inch thick). Transfer the dough to a 9-inch standard pie plate. Trim the excess dough and fold it to make a decorative edge. Wrap in plastic wrap and freeze for at least 15 minutes. Line the frozen shell with parchment paper or foil and fill with pie weights. Bake the crust until the edges are lightly golden and the crust beneath the parchment is dry, about 25 minutes. Remove the parchment and weights and continue to bake the crust until it is golden brown about 15 to 20 minutes. Transfer the pan to a wire rack to cool completely. Set a fine mesh sieve next to the crust for later.
• Prepare the filling: In a small saucepan, bring the maple syrup to a boil over high heat, then lower the heat to maintain a gentle simmer. Continue to cook the syrup until it has reduced by about half, about 12 minutes. (You can occasionally pour the syrup into a glass measuring cup to check the volume.) In a medium saucepan (away from the stovetop), whisk the egg yolks with the cornstarch until smooth. In a slow stream, while whisking, add the milk and cream. Add the salt, butter, and reduced maple syrup. Don't worry if the syrup seizes. It will smooth out in the next step when you heat the custard. Cook the milk mixture over medium heat, stirring constantly with a wooden spoon, until it has thickened and come to a low boil, about 7 minutes. Cook the custard for 1 minute more and then pour it through the sieve into the cooled crust and spread it out evenly.
• Press a piece of waxed paper directly onto the surface of the custard and transfer the pie to the fridge. Chill the pie for at least 4 hours or up to overnight. To serve, top the pie with whipped cream.
