Citrus Mousse Cake With Buttercream Frosting Recipes

Steps:

• Sprinkle gelatin over 2 tablespoons cold water; let stand until soft, about 5 minutes. Meanwhile, in a medium saucepan off heat, whisk together 1 cup granulated sugar, zest, and egg yolks. Whisk in lime and lemon juices and salt. Add butter; place over medium-high heat. Cook, whisking constantly, until butter has melted, mixture is thick enough to coat the back of a spoon, and small bubbles form around edge of pan, about 5 minutes. Stir in gelatin mixture; cook until completely dissolved, about 1 minute more.
• Pour curd through a fine-mesh sieve into a nonreactive bowl. Press plastic wrap against surface of curd; refrigerate until cold, about 1 hour (or stir over an ice bath until chilled, about 15 minutes).
• 3. Whisk cream with confectioners' sugar until stiff peaks form. Whisk curd briefly to loosen, then fold in whipped cream. Beat egg whites with whisk attachment until soft peaks form, then gradually beat in remaining 1/4 cup granulated sugar until stiff peaks form. Gently fold into curd mixture. Refrigerate in an airtight container at least 1 hour and up to 2 days.

Steps:

• Heat oven to 350°F for shiny metal pans (325°F for dark or nonstick pans). Grease and slightly flour bottoms and sides of two 8- or 9-inch round cake pans with shortening or cooking spray; lightly flour (or spray with cooking spray or baking spray with flour).
• In large bowl, beat cake ingredients with electric mixer on low speed 30 seconds, then on medium speed 2 minutes, scraping bowl occasionally. Pour into pans.
• Bake and cool as directed on box for 8- or 9-inch rounds.
• In chilled medium bowl, beat whipping cream and powdered sugar with electric mixer on high speed until stiff peaks form. Fold in 1/2 cup of the pie filling and the grated orange peel.
• Place 1 cake layer, rounded side down, on serving plate. Spread remaining pie filling over layer to within 1/4 inch of edge. Top with second layer, rounded side up. Spread whipped cream mixture over side and top of cake. Garnish top of cake with strips of lemon and orange peel. Store covered in refrigerator.

Steps:

• Make the cake: Heat oven to 350 degrees. Line a 9-by-13-inch baking pan with parchment paper, butter and flour the paper.
• In a measuring cup with a spout, combine the milk and lemon juice. Whisk the flour, baking powder, baking soda and salt together in a medium bowl.
• In the bowl of a stand mixer fitted with the paddle attachment, cream butter, sugar and lemon zest until light and fluffy, about 5 minutes. Add eggs, one at a time, mixing for about 30 seconds after each. Scrape down bottom and sides of the mixer to ensure the mixture is well combined.
• With the mixer on low speed, alternately add the flour mixture and milk mixture to the bowl in three additions. Mix until just combined, then use a rubber spatula to finish mixing the batter. Pour the batter into the prepared pan, smooth the top and tap the pan on the counter a few times to release any large air pockets. Bake for 35 to 40 minutes or until puffed and golden and a cake tester inserted into the center comes out clean. Cool the cake completely on a rack before frosting.
• Meanwhile, prepare the frosting: Combine the butter, confectioners' sugar, lemon zest and a pinch of salt in the bowl of a stand mixer fitted with the paddle attachment. Mix on low until combined, then turn the mixer up to medium-high and stream in 3 tablespoons of lemon juice. Whip the frosting until very light and fluffy, about 5 minutes, adding additional lemon juice as necessary until frosting is smooth and spreadable.
• Spread the frosting over the cooled cake and serve. Store leftover cake at room temperature, covered for up to 2 days.

Steps:

• Make cake layers:
• Preheat oven to 350°F. Butter 2 (8- by 2-inch) round cake pans and dust with flour, knocking out excess.
• Put sugar and zests in a food processor and pulse until blended well, about 30 seconds. Sift together flour, baking powder, baking soda, and salt.
• Beat butter in large bowl of standing electric mixer until light and fluffy, about 2 minutes. Gradually beat in sugar mixture and beat at high speed 5 minutes. Beat in egg yolks, 1 at a time, and beat until light and fluffy, about 4 minutes. Add one fourth of flour mixture and beat on low speed until just combined. Beat in milk until just blended. Beat in remaining flour mixture alternately with juices in 3 batches, beginning and ending with flour mixture.
• Divide batter evenly between cake pans and smooth tops. Bake in middle of oven until golden and a tester comes out clean, about 30 minutes. Cool layers on racks 5 minutes. Run a thin knife around edges of pans, then invert cakes onto racks to cool completely.
• Make buttercream:
• Heat whites and sugar in a metal bowl set over a saucepan of simmering water, whisking constantly, until sugar is dissolved and a thermometer registers 160°F. Remove bowl from heat and beat mixture in standing electric mixer on medium-high speed until thick, glossy peaks form. If mixture is still warm, continue beating until cool.
• With mixer running, add butter, 1 tablespoon at a time, beating well after each addition. Add liqueur and lemon juice, beating on high speed until smooth and fluffy, about 10 minutes. If buttercream begins to separate, beat on high speed until smooth.
• Assemble cake:
• Brush any loose crumbs from layers and put 1 upside down on a serving plate. Spread with about 1 cup buttercream. Place other layer on top, right side up. Frost top and sides of cake with remaining buttercream.

Steps:

• Preheat oven to 325 degrees. Butter two 8-by-2-inch round cake pans. Line with parchment; butter parchment. Dust with flour, tapping out excess.
• Whisk together flour, baking powder, baking soda, and salt until thoroughly combined, 30 seconds. Beat butter with sugar and zest until light and fluffy. Beat in eggs, one at a time, thoroughly combining after each addition and scraping down bowl as needed. Beat in lemon juice. With mixer on low, add flour mixture in 3 batches, alternating with buttermilk and beginning and ending with flour.
• Divide batter evenly between prepared pans, smoothing tops with an offset spatula. Bake, rotating pans halfway through, until tops spring back when lightly touched and are light golden, about 1 hour, 10 minutes. Transfer pans to wire racks; let cool 10 minutes. Turn out of pans, remove parchment, and let cool completely, about 2 hours. Cakes can be made to this point and refrigerated, well wrapped in plastic, up to 1 day.
• Trim tops of cakes flat. Split each cake horizontally into 3 equal layers. Line an 8-inch cake pan with 2 parchment strips, leaving a 3-inch overhang on all sides. Place 1 cake layer in pan, bottom-side down. Spread 1 cup mousse evenly over it; top with a second cake layer. Repeat, spreading 1 cup mousse between each layer. Finish with a cake layer, bottom-side up. Refrigerate, covered in plastic, at least 1 hour and up to overnight.
• Turn cake out of pan onto a cake plate. Spread 1 cup buttercream evenly over top and sides to create a crumb coat. Refrigerate 15 minutes. Spread remaining 3 cups buttercream over top and sides. Decorate as desired.

Steps:

• In a large bowl, beat together whipped topping and condensed milk. Gradually beat in lemon and grapefruit juices, until evenly blended.
• Pour the mousse into one bowl or divide it into individual serving dishes. Garnish with fruit, if desired.
