Boston Cream Filling Recipes

Steps:

• For the filling: In a medium saucepan off-heat, whisk together the sugar, cornstarch and salt. Stir in the whole egg and the 3 yolks, and then stir in the milk. Turn the heat on to medium high and cook the mixture, uncovered, stirring constantly, until the custard thickens, 12 to 15 minutes. Remove the pan from the heat and stir in the vanilla. Transfer to a bowl, cover with plastic wrap and refrigerate while you make the cake. Be sure to place the plastic wrap directly onto the custard to prevent a skin from forming.
• For the cake: Preheat the oven to 350 degrees F. Spray a 9-inch round cake pan with cooking spray and set aside.
• Using an electric mixer, cream the butter and sugar together until fluffy, about 5 minutes. Add the egg and mix until completely combined. Sift together the cake flour, baking powder and salt in a bowl. Add the flour mixture to the butter mixture alternating with the milk, beginning and ending with the flour. Add the vanilla.
• Pour the batter into the prepared pan and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean. Remove the cake from the oven and allow to cool in the pan for 10 minutes, then turn out onto a rack to cool completely, about 20 minutes.
• For the topping: To make the chocolate ganache, in a medium saucepan over medium-high heat, bring the cream to a boil, then immediately remove from the heat. Add the chocolate chips to the cream and stir until completely melted.
• To assemble, slice the cake layer in half horizontally. Spread the custard filling onto one layer, then top with the second layer of cake. Spread the ganache over the top of the cake using an offset spatula or the back of a spoon, allowing it to drizzle down the sides. Refrigerate for at least 2 hours before serving. Store covered in the fridge for up to 2 weeks.

Steps:

• Heat oven to 350 degrees. Lightly butter and flour a 9-inch-round cake pan. Line with parchment paper; set aside.
• Sift together the cake flour and the salt. Sift again, twice; set aside. In the bowl of an electric mixer fitted with the whisk attachment, mix the eggs and sugar until well combined. Place the bowl over a pot of gently simmering water; whisk until mixture is warm, about 110 degrees, and the sugar is dissolved, about 6 minutes. Remove from heat; place bowl on mixer. With the whisk attachment, beat the egg mixture on high until thickened and pale, about 6 minutes.
• Meanwhile, in a small saucepan, combine the milk and split vanilla bean. Place over medium heat until hot, being careful not to let boil. Remove and discard vanilla bean. With egg mixture beating, pour the hot milk into the egg mixture in a slow, steady stream. Turn off mixer. Transfer to a medium bowl; fold in the flour mixture. Pour into prepared pan.
• Bake until cake is golden brown and springs back when gently pressed, about 30 minutes. Transfer to wire rack to cool for 15 minutes. Remove from pan; cool completely.
• In a large bowl, whisk the egg yolks; set aside. In a medium saucepan, combine sugar, cornstarch, and salt. Gradually stir in the milk. Cook over medium heat, stirring constantly, until mixture thickens and begins to bubble, about 5 minutes. Remove from heat.
• Slowly pour the hot milk mixture into the egg yolks while whisking. Return mixture to saucepan. Cook over medium heat, stirring constantly, until mixture begins to bubble, about 2 minutes. Remove from heat; stir in the vanilla extract.
• Transfer filling to a medium bowl. Cover with plastic wrap, pressing wrap against the filling to prevent a skin from forming; chill in refrigerator until firm, at least 1 hour.
• Split the cake into two layers; spread the bottom half with chilled filling. Place in refrigerator to set, about 30 minutes. Wrap remaining half of cake with plastic wrap; set aside.
• In a medium-size heat-proof bowl, or the top of a double boiler, set over a pot of gently simmering water, combine the chocolate and the heavy cream. Stir occasionally until the chocolate melts, about 12 minutes. Remove from heat; set aside to cool for 10 minutes.
• Remove cake from refrigerator; top with reserved layer. Transfer cake to serving plate; pour chocolate glaze over top. Allow to set 20 minutes before serving.

Steps:

• Preheat oven to 375 degrees F (190 degrees C). Grease and flour two 9 inch round cake pans. Sift the all-purpose flour, cake flour, baking powder and salt together and set aside.
• In a deep bowl cream 6 tablespoons of the butter with 3/4 cup sugar until light and fluffy. Beat in the 2 eggs, one at a time, then beat in the 1 teaspoon vanilla extract. Add the flour mixture alternately with the 1/2 cup of the milk in 3 additions, Beating the batter smooth after each addition. Divide the batter between the 2 prepared pans.
• Bake at 375 degrees F (190 degrees C) for 15 minutes or until cakes begin to shrink away from the sides of the pans and centers spring back when lightly touched. Turn the cakes onto wire racks to cool.
• To Make The Filling: Combine the 1/2 cup light cream with 1/4 cup of the milk and cook over medium heat until bubbles begin to form around the edge of the pan. Immediately add 1/4 cup of the sugar and the salt, stirring until dissolved. Remove the pan from the heat.
• In a small bowl, combine 1/4 cup of the milk with the cornstarch and whisk to remove lumps. Whisk in the 2 eggs. Add the hot cream mixture in a thin stream, whisking constantly. Return to the mixture to the saucepan, bring to a boil, and cook over low heat, stirring constantly, until the custard thickens and is smooth (about 5 minutes). Remove from heat and stir in the 1/2 teaspoon vanilla and allow to cool to room temperature.
• To Make The Chocolate Frosting: In a heavy saucepan over low heat, stir the chocolate pieces and 2 tablespoons butter until they are completely melted. Remove from the heat and, stirring constantly, add the 1/4 cup light cream in a thin steady stream. When mixture is smooth, stir in the confectioners' sugar and beat vigorously. Stir in the 1/2 teaspoon vanilla.
• To Assemble Cake: Spread the cooled filling over one the cooled cakes and place the second cake on top. Pour the chocolate frosting evenly over the top allowing it to spill down the sides.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease and flour one 9 inch round cake pan.
• Beat the flour, 1 cup sugar, baking powder, salt, 3/4 cup milk, shortening, 1 egg, and 1 teaspoon vanilla at low speed, scraping bowl constantly for 30 seconds. Beat on high speed, scraping bowl occasionally for 3 minutes. Pour batter into the prepared pan.
• Bake at 350 degrees F (175 degrees C) for 30 to 35 minutes or until a wooden pick inserted near the center comes out clean. Remove from the pan and let cool on a wire rack.
• To Make The Cream Filling: In a 2 quart saucepan, mix 1/3 cup of the sugar, the cornstarch and salt. Stir in the milk gradually and cook over medium heat, stirring constantly, until the mixture thickens and boils. Boil and stir 1 minute. Stir at least 1/2 of the mixture slowly into the egg yolks. Return egg yolk mixture to the saucepan and boil and stir for 1 minute. Remove from heat and stir in the 2 teaspoons vanilla. Let cool to room temperature.
• To Make Chocolate Glaze: Heat the chocolate and butter or margarine over low heat until melted. Remove from the heat and stir in the confectioners' sugar, and vanilla. Stir in the water, one teaspoon at a time, until glaze is of desired consistency.
• To Assemble the Cake: Split the cooled cake in half to make 2 thin layers. Fill the layers with the filling. Then spread the chocolate glaze over the top. Refrigerate any leftover cake.

Steps:

• Heat the milk until it is warm but not hot, about 90 degrees. In a large bowl, combine it with the yeast. Stir lightly, and let sit until the mixture is foamy, about 5 minutes.
• Using an electric mixer or a stand mixer fitted with a dough hook, beat the eggs, butter, sugar and salt into the yeast mixture. Add half of the flour (2 cups plus 2 tablespoons), and mix until combined, then mix in the rest of the flour until the dough pulls away from the sides of the bowl. Add more flour, about 2 tablespoons at a time, if the dough is too wet. If you're using an electric mixer, the dough will probably become too thick to beat; when it does, transfer it to a floured surface, and gently knead it until smooth. Grease a large bowl with a little oil. Transfer the dough to the bowl, and cover. Let rise at room temperature until it doubles in size, about 1 hour.
• Turn the dough out onto a well-floured surface, and roll it to 1/2-inch thickness. Cut out the doughnuts with a doughnut cutter, concentric cookie cutters or a drinking glass and a shot glass (the larger one should be about 3 inches in diameter), flouring the cutters as you go. Reserve the doughnut holes. If you're making filled doughnuts, don't cut out the middle. Knead any scraps together, being careful not to overwork, and let rest for a few minutes before repeating the process.
• Put the doughnuts on two floured baking sheets so that there is plenty of room between each one. Cover with a kitchen towel, and let rise in a warm place until they are slightly puffed up and delicate, about 45 minutes. If your kitchen isn't warm, heat the oven to 200 at the beginning of this step, then turn off the heat, put the baking sheets in the oven and leave the door ajar.
• About 15 minutes before the doughnuts are done rising, put the oil in a heavy-bottomed pot or Dutch oven over medium heat, and heat it to 375. Meanwhile, line cooling racks, baking sheets or plates with paper towels.
• Carefully add the doughnuts to the oil, a few at a time. If they're too delicate to pick up with your fingers (they may be this way only if you rose them in the oven), use a metal spatula to pick them up and slide them into the oil. It's O.K. if they deflate a bit; they'll puff back up as they fry. When the bottoms are deep golden, after 45 seconds to a minute, use a slotted spoon to flip; cook until they're deep golden all over. Doughnut holes cook faster. Transfer the doughnuts to the prepared plates or racks, and repeat with the rest of the dough, adjusting the heat as needed to keep the oil at 375.
• For the glaze, whisk together 1 3/4 cups powdered sugar, 1/4 cup unsweetened cocoa powder, 1/4 cup milk and 1 teaspoon vanilla until smooth. Dip the tops of the doughnuts in the glaze, and let it harden on a rack.
• Combine 2/3 cup sugar, 2 tablespoons flour, 2 tablespoons cornstarch and a pinch of salt in a small saucepan. Over medium heat, whisk in 2 eggs and 2 cups cream. Continue cooking, whisking almost constantly, until the mixture just begins to boil and thickens, about 10 minutes. Adjust the heat so the mixture bubbles gently; cook until it coats the back of a spoon (when you draw your finger through this coating, the resulting line should hold its shape). Stir in 2 tablespoons softened unsalted butter and 2 teaspoons vanilla. Strain through a fine-mesh sieve, and cool to room temperature before using.
• To fill the doughnuts with the pastry cream, insert the tip of a pastry bag filled with cream into the side of the doughnut, and squeeze. (Alternatively, poke a chopstick into the side of the doughnut, and wiggle it around to hollow out some space inside. Plunge a small funnel into the hole, spoon some filling into the funnel and use the chopstick to push it into the doughnut. If the filling clumps up toward the center of the doughnut, just press lightly on the top to distribute it evenly.)

Steps:

• Combine sugar, cornstarch & salt in saucepan. Add milk, vanilla & egg yolks, stir with wire wisk until blended. Cook over medium heat, strring constantly until thickened. Cool completely.
• You can also add a cup of whipped cream to make a fluffier, moussie type filling, or 2 oz. of baking chocolate for a chocolatey one.

Steps:

• For custard, in a heavy saucepan, mix sugar and cornstarch; whisk in milk and egg yolks. Cook and stir over medium heat; bring to a gentle boil. Cook and stir 1 minute; remove from heat. Stir in butter until melted. Immediately transfer to a clean bowl; stir in vanilla. Press plastic wrap onto surface of filling; cool 30 minutes. Refrigerate until cold., While custard is chilling, make cake layers. Preheat oven to 375°. Line bottoms of 2 greased 8-in. round baking pans with parchment; grease paper and dust with flour., In a large bowl, cream sugar and shortening until light and fluffy, about 5 minutes. Add eggs, one at a time, beating well after each addition. Beat in vanilla. In another bowl, whisk flour, baking powder and salt; add to creamed mixture alternately with milk, beating well after each addition., Transfer to prepared pans. Bake until a toothpick inserted in center comes out clean, 15-20 minutes. Cool in pans 10 minutes before removing to wire racks; remove paper. Cool completely., For glaze, in a small saucepan, bring water and butter to a simmer; immediately remove from heat and whisk in cocoa powder. Beat in confectioners' sugar and vanilla until smooth; cool slightly. , Place one cake layer on a serving plate; spread with cold custard. Top with the second cake layer. Spoon chocolate glaze over the top, allowing it to drip down sides of cake. Refrigerate until serving.

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.
