Whole Egg Lemon Buttercream Recipes

WHOLE-EGG LEMON BUTTERCREAM

Steps:

• Bring 1 cup water to just below a simmer in a medium saucepan over medium-low heat. Using a handheld whisk, combine eggs, sugar, and salt in the bowl of a stand mixer. Place bowl on top of saucepan (it should not touch water) and cook egg mixture, whisking constantly, until lightened in color, thickened slightly, and an instant-read thermometer registers 160°F. Remove from heat and beat with stand mixer fitted with the whisk attachment on medium speed until completely cooled and tripled in volume, about 10 minutes. Add butter, 1-2 Tbsp. at a time, beating well after each addition until fully incorporated. Add vanilla and lemon curd and beat on medium-low speed until just combined.
• Do Ahead
• Buttercream can be made and refrigerated up to 5 days in advance or frozen up to 1 month. To use refrigerated buttercream, let sit at room temperature until soft, at least 2 hours. Beat with stand mixer fitted with the paddle attachment on medium speed until smooth. If texture is not smooth, beat in a little water, 1 tsp. at a time. To defrost, transfer buttercream from freezer to refrigerator to thaw overnight. Then follow the instructions for using refrigerated buttercream.

ROSEMARY OLIVE OIL CAKE WITH LEMON BUTTERCREAM

Steps:

• Make the cake: Preheat the oven to 300˚ F. Coat two 8-inch round cake pans with cooking spray. Combine the sugar, 2 1/3 cups flour, the baking powder, salt and 2 egg yolks in a large bowl; beat with a mixer on medium-high speed until well mixed. Stream in 1 cup olive oil and mix about 30 seconds. Beat in the 3 whole eggs, one at a time. Stream in the milk and vanilla and mix until combined.
• In a separate bowl, combine the chopped rosemary, remaining 2 teaspoons olive oil and 3 teaspoons flour. Fold the rosemary mixture into the batter.
• Pour the batter into the cake pans. Bake until a toothpick inserted into the centers comes out clean, 20 to 30 minutes. Transfer to a rack and let cool completely in the pans.
• Make the lemon curd: In a small saucepan, combine 1/4 cup sugar, the egg yolk, lemon zest and juice, cornstarch and 1 tablespoon butter. Stir continuously with a rubber spatula until the mixture boils and thickens, about 1 minute. Transfer the lemon curd to a bowl and place a piece of plastic wrap directly on the surface to prevent a skin from forming. Refrigerate to cool.
• Make the buttercream: Set up a stand mixer with the whisk attachment. In a medium saucepan, heat the egg whites and remaining 1 cup sugar over medium heat until the mixture reaches 160˚ F and the sugar is dissolved. (You should not be able to feel any sugar granules and the mixture should be very warm, not hot, to the touch.)
• Pour the egg white mixture into the mixer bowl and whisk on medium-high speed until the meringue is three times its volume, holds firm peaks and has cooled to about 95˚ F, about 4 minutes. Beat in the remaining 4 sticks butter slowly, piece by piece, until smooth and blended. Beat in the salt and vanilla.
• Remove the lemon curd from the refrigerator and fold it into the buttercream until well combined.
• Assemble the cake: Transfer 1 cake layer to a cake plate. Spread some of the buttercream on top using an offset spatula. Top with the other cake layer. Cover the top and sides of the cake with a thin layer of buttercream (this is the crumb coat); refrigerate 15 to 20 minutes. Cover with the remaining buttercream.

LEMON MERINGUE BUTTERCREAM

Steps:

• Make lemon curd:
• In a small heavy saucepan whisk together yolks and sugar and whisk in lemon juice, butter, and a pinch of salt. Cook mixture over moderately low heat, whisking, until it reaches boiling point, 5 to 7 minutes (do not let it boil). Strain curd through a fine sieve into a bowl and cool, its surface covered with a plastic wrap. Chill curd, covered at least 4 hours or overnight.
• Make buttercream:
• In a heavy saucepan combine sugar and water and bring to a boil, stirring until sugar is dissolved. Boil syrup, undisturbed, until it reaches 248°F on candy thermometer. While syrup is boiling, in a standing electric mixer beat whites with a pinch salt until foamy and beat in cream of tarter. Beat whites until they just hold stiff peaks and add hot syrup in a stream, beating. Beat mixture at medium speed until completely cool, 15 to 20 minutes. Beat in butter, 1 piece at a time, and beat until it is thick and smooth. (Buttercream will at first appear very thin but as more butter is beaten in, it will thicken.) Beat in lemon curd and salt, beating until smooth, and drizzle in framboise, 1 tablespoon at a time, beating. Buttercream may be made 4 days ahead and chilled in an airtight container or 2 weeks ahead and frozen in anairtight container. Let buttercream come completely to room temperature (this may take several hours if frozen) and beat before using.

Steps:

• Make the filling and crumb coat: Cook egg whites and sugar in a small saucepan over medium heat, whisking constantly until sugar is completely dissolved.

With the mixer on medium-low, add butter, one piece at a time, mixing well after each addition.
• Remove whisk attachment and switch to paddle attachment. Increase speed to high and beat until buttercream comes together, about 5 minutes; beat in lemon extract.

Steps:

• Preheat oven to 350 degrees F (175 degrees C). Grease and flour two 8 inch round pans. Mix together the flour, baking powder and salt. Set aside.
• In a large bowl, cream together the butter and sugar until light and fluffy, about 5 minutes. Beat in the eggs one at a time, then stir in the vanilla. Beat in the flour mixture alternately with the milk, mixing just until incorporated.
• Pour batter into prepared pans. Bake in the preheated oven for 30 minutes, or until a toothpick inserted into the center of the cake comes out clean. Allow to cool in pans on wire racks for 10 minutes. Then invert onto wire racks to cool completely.
• To make filling: In medium saucepan, mix together 1 tablespoon lemon zest, 1/2 cup lemon juice and 1 tablespoon cornstarch until smooth. Mix in 6 tablespoons butter and 3/4 cup sugar, and bring mixture to boil over medium heat. Boil for one minute, stirring constantly. In small bowl, with a wire whisk, beat egg yolks until smooth. Whisk in a small amount of the hot lemon mixture. Pour the egg mixture into the sauce pan, beating the hot lemon mixture rapidly. Reduce heat to low; cook, stirring constantly, 5 minutes, or until thick (not to boil).
• Pour mixture into medium bowl. Press plastic wrap onto surface to keep skin from forming as it cools. Cool to room temperature. Refrigerate 3 hours.
• To make frosting: In large bowl, beat confectioners' sugar, 1/2 cup butter, 2 tablespoons lemon juice and 1 teaspoon lemon zest until smooth. Beat in milk, and increase speed and continue to beat until light and fluffy.
• To assemble: With long serrated knife, split each cake layer in half horizontally, making 4 layers. Place 1 layer, cut side up, on a serving plate. Spread with half of the lemon filling. Top with another layer, and spread with 1/2 cup frosting. Add third layer, and spread with remaining half of the lemon filling. Press on final cake layer, and frost top and sides of cake with remaining frosting. Refrigerate cake until serving time.
