BOSTON CREAM PIE ORIGINAL HOTEL RECIPES

Steps:

• Preheat oven to 350 degrees F (175 degrees C).
• Spray 2 (8-inch) cake pans with cooking spray.
• Stir yellow cake mix, 3 eggs, water, and vegetable oil in a bowl until moistened. Beat with an electric mixer on medium speed for 2 minutes, scraping bowl occasionally.
• Divide cake batter between the two prepared cake pans.
• Bake in the preheated oven until cakes have risen and are lightly golden brown, 33 to 38 minutes. Check for doneness after 25 minutes. A toothpick inserted into the center of the cakes should come out clean. Allow cakes to cool for about 10 minutes before removing from the pans. Cool cakes completely, about 40 minutes.
• Whisk 3 eggs, cornstarch, and sugar in a large bowl until well mixed and lemon colored, 2 to 3 minutes. Set aside.
• Heat 1 cup heavy whipping cream, whole milk, and 1/2 tablespoon butter in a large saucepan over medium heat until it just begins to boil.
• Reduce heat to low; pour egg mixture into cream mixture and whisk until thick, about 1 minute.
• Pour egg and cream mixture through a fine mesh strainer into a large bowl; discard any chunks.
• Whisk vanilla and salt into the egg and cream mixture until combined. Cover with a layer of plastic wrap pressed against the surface. Chill in refrigerator to form a pastry cream texture, 3 to 4 hours.
• Place chocolate in a large bowl. Heat 1 teaspoon butter and 1/2 cup heavy whipping cream in a saucepan over medium heat until butter is melted. Pour cream mixture over chocolate and whisk until smooth. Set aside until cooled, but still pourable, about 20 minutes.
• Place one cake layer on a plate, flat side up. Spread pastry cream to within 1-inch of the edge of cake. Place second cake layer on top, rounded side up. Press gently to push pastry cream to the edge. Pour chocolate mixture over top of the cake and spread so it drips over the edge.

Steps:

• Place an egg separator over a small bowl. Crack open 1 egg over the egg separator to seperate the yolk from the white; then separate the other egg. (Save the whites for another recipe.) In a small bowl, place the yolks. Beat the egg yolks with a fork or wire whisk until mixed. Stir in 1 1/2 cups milk; set aside.
• In a 2-quart saucepan, stir 1/3 cup granulated sugar, the cornstarch and 1/8 teaspoon salt until mixed. Gradually stir egg mixture into sugar mixture. Cook over medium heat, stirring constantly, until mixture thickens and boils. Boil and stir 1 minute; remove from heat. Stir in 2 teaspoons vanilla. Press plastic wrap on surface of filling to prevent a tough layer from forming on top. Refrigerate at least 2 hours until set but no longer than 24 hours. While filling is chilling, continue with recipe.
• Heat the oven to 350°F. Spray just the bottom of a 9-inch round cake pan with baking spray with flour.
• In a large bowl, beat all cake ingredients with an electric mixer on low speed 30 seconds, stopping frequently to scrape batter from side and bottom of bowl with a rubber spatula. Beat on high speed 3 minutes, stopping occasionally to scrape bowl. Pour batter into the pan; use a rubber spatula to scrape batter from bowl, spread batter evenly in pan and smooth top of batter.
• Bake about 35 minutes or until a toothpick inserted in the center comes out clean. Cool cake in pan on a cooling rack 20 minutes, then remove onto cooling rack to finish cooling completely, about 1 hour.
• In a 1-quart saucepan, melt 3 tablespoons butter and the chocolate over low heat, stirring occasionally. Meanwhile, in 1-cup glass measuring cup, microwave the water uncovered on High 15 to 30 seconds or until hot. Remove chocolate mixture from heat. Stir in the powdered sugar and 3/4 teaspoon vanilla. Stir in 3 tablespoons hot water. Stir in additional water, 1 teaspoon at a time, until icing is smooth and thin enough to spread.
• To split cake horizontally in half, mark middle points around side of cake with toothpicks. Using toothpicks as a guide, cut through the cake with a long, sharp knife, using a back-and-forth motion. On a serving plate, place bottom layer with the cut side up. Spread filling over bottom layer. Top with top of cake, cut side down.
• Spread glaze over top of cake, using a metal spatula or back of a spoon, letting some glaze drizzle down side of cake. Refrigerate uncovered until serving. Store any remaining cake covered in the refrigerator.
