Stepping outside the box.
Maybe a little one-on-one time.
You and me.
Boston Cream Pie
1/2 cup cake flour
1/4 cup unbleached all-purpose flour
1 teaspoon baking powder
1/4 teaspoon table salt
3 tablespoons milk
2 tablespoons unsalted butter
1/2 teaspoon vanilla extract
5 eggs , room temperature
3/4 cup granulated sugar
2 cups milk
6 large egg yolks
1/2 cup granulated sugar
1/4 teaspoon table salt
1/4 cup cornstarch , sifted
1 teaspoon vanilla extract
1 tablespoon rum or 1 teaspoon rum flavoring
2 tablespoons unsalted butter (optional)
Rich Chocolate Glaze
1 cup heavy cream
1/4 cup light corn syrup
8 ounces semisweet chocolate , chopped into small pieces
1/2 teaspoon vanilla
1. For the sponge cake: Adjust oven rack to lower middle position and heat oven to 350 degrees. Grease two 8- or 9-inch cake pans and cover pan bottoms with a round of parchment paper. Whisk flours, baking powder, and salt in a medium bowl (or sift onto waxed paper). Heat milk and butter in a small saucepan over low heat until butter melts. Remove from heat and add vanilla; cover and keep warm.
2. Separate three of the eggs, placing whites in bowl of standing mixer fitted with whisk attachment (or large mixing bowl if using hand mixer or whisk) and reserving the 3 yolks plus remaining 2 whole eggs in another mixing bowl. Beat the 3 whites on high speed (or whisk) until whites are foamy. Gradually add 6 tablespoons of the sugar; continue to beat whites to soft, moist peaks. (Do not overbeat.) If using a standing mixer, transfer egg whites to a large bowl and add yolk/whole egg mixture to mixing bowl.
3. Beat yolk/whole egg mixture with remaining 6 tablespoons sugar. Beat on medium-high speed (setting 8 on a KitchenAid) until eggs are very thick and a pale yellow color, about 5 minutes (or 12 minutes by hand). Add beaten eggs to whites.
4. Sprinkle flour mixture over beaten eggs and whites; fold very gently 12 times with a large rubber spatula. Make a well in one side of batter and pour milk mixture into bowl. Continue folding until batter shows no trace of flour, and whites and whole eggs are evenly mixed, about 8 additional strokes.
5. Immediately pour batter into prepared baking pans; bake until cake tops are light brown and feel firm and spring back when touched, about 16 minutes for 9-inch cake pans and 20 minutes for 8-inch cake pans.
6. Immediately run a knife around pan perimeter to loosen cake. Cover pan with large plate. Using a towel, invert pan and remove pan from cake. Peel off parchment. Re-invert cake from plate onto rack . Repeat with remaining cake.
7. For the pastry cream: Heat milk in a small saucepan until hot but not simmering. Whisk yolks, sugar, and salt in a large saucepan until mixture is thick and lemon-colored, 3 to 4 minutes. Add cornstarch; whisk to combine. Slowly whisk in hot milk. Cook milk mixture over medium-low heat, whisking constantly and scraping pan bottom and sides as you stir, until mixture thickens to a thick pudding consistency and loses all traces of raw starch flavor, about 10 minutes. Off heat, stir in vanilla, rum, and butter (if using) and transfer to another container to cool to room temperature, placing a piece of plastic wrap directly on surface of mixture to prevent skin from forming. Refrigerate pastry cream until firm. (Can be refrigerated overnight.) To ensure that pastry cream does not thin out, do not whisk once it has set.
8. For the glaze: Bring cream and corn syrup to a full simmer over medium heat in a medium saucepan. Off heat, add chocolate; cover and let stand for 8 minutes. (If chocolate has not completely melted, return saucepan to low heat; stir constantly until melted.) Add vanilla; stir very gently until mixture is smooth. Cool until tepid so that a spoonful drizzled back into pan mounds slightly. (Glaze can be refrigerated to speed up cooling process, stirring every few minutes to ensure even cooling.)
9. While glaze is cooling, place one cake layer on a cardboard round on cooling rack set over waxed paper. Carefully spoon pastry cream over cake and spread evenly up to cake edge. Place the second layer on top, making sure layers line up properly.
10. Pour glaze over middle of top layer and let flow down cake sides. Use a metal spatula, if necessary, to completely coat cake. Let sit until glaze fully sets, about 1 hour. Serve.
