Vanilla Sponge Cake With Strawberry Meringue Buttercream Recipes

Steps:

• Cake: Preheat oven to 325 degrees. Coat an 8-inch springform pan with cooking spray. Line sides with a 5-inch-high strip of parchment; coat parchment with cooking spray.
• Whisk together flour, 3/4 cup granulated sugar, baking powder, and salt until thoroughly combined, 30 seconds. In a large bowl, whisk together butter, egg yolks, and milk to combine. Whisk flour mixture into butter mixture until smooth.
• Beat egg whites on medium-low speed until frothy, about 2 minutes. Add cream of tartar and vanilla and beat on medium-high until soft peaks form, 2 minutes more. Gradually add remaining 3/4 cup granulated sugar and beat until stiff, glossy peaks form, about 5 minutes. Whisk one-third of egg-white mixture into batter. Gently but thoroughly fold in remaining egg-white mixture with a rubber spatula. Transfer batter to pan; gently smooth top with spatula.
• Bake until risen and golden brown, about 45 minutes. Reduce oven to 300 degrees and continue to bake until top springs back when lightly touched, about 35 minutes more. Transfer pan to a wire rack; let cool 10 minutes. Unlock pan and carefully lift to remove. Remove parchment and turn cake out onto rack, running a sharp knife between cake and pan bottom to release. Remove bottom and turn cake top-side up; let cool completely.
• Frosting: In a food processor, puree 1 pound strawberries with 1/2 cup granulated sugar until smooth. Transfer to a medium saucepan and bring to a boil, then reduce heat to medium and cook, stirring frequently, until darkened, thick, and syrupy, about 10 minutes. Strain through a fine-mesh sieve, pressing on solids to remove as much liquid as possible (you should have 1 cup). Refrigerate, covered, until room temperature, about 1 hour (or transfer to a bowl set in an ice-water bath and stir occasionally until cool to the touch, about 10 minutes).
• Combine egg whites, remaining 1 1/4 cups granulated sugar, and salt in a heatproof standmixer bowl set over (not in) a pot of simmering water, whisking constantly until sugar is dissolved and mixture is warm. (It should feel completely smooth when rubbed between your fingertips.) Transfer bowl to mixer fitted with the whisk attachment. Starting on low speed and gradually increasing to medium-high, beat until stiff, glossy peaks form. Continue beating until bottom of bowl is cool to the touch, about 10 minutes.
• Reduce speed to medium-low and beat in butter, a few tablespoons at a time, until combined, scraping down bowl as needed. Slowly add strawberry puree and vanilla, beating until combined. (If buttercream appears curdled, increase speed to medium-high and beat until smooth.)
• Slice 1 pound strawberries lengthwise, 1/4 inch thick (you should have about 2 1/2 cups). Cut cake horizontally into 3 even layers with a serrated knife. Transfer bottom layer, cut-side up, to a cake plate or stand lined with parchment strips. Spread top evenly with 3/4 cup buttercream and half of sliced strawberries, overlapping berries to fit. Spread another 3/4 cup buttercream onto one side of center cake layer and place over first cake layer, frosted-side down. Press gently to adhere, being careful not to allow strawberries to slide out. Spread top with another 3/4 cup buttercream; top evenly with remaining sliced strawberries. Spread another 3/4 cup buttercream onto cut side of top cake layer; place on center cake, frosted-side down, pressing gently to adhere.
• Using a small offset metal spatula, spread remaining buttercream evenly over top and sides of cake. To create decorative sides, hold spatula vertically against cake and press one long side gently into frosting (do not go deeper than 1/4 inch, so you don't get down to cake), then pull spatula directly upward in one motion. Repeat around entire cake, then remove parchment strips. Top cake with remaining 1 pound strawberries, cutting some in half, if desired. Dust lightly with confectioners' sugar; serve. This cake is best assembled, kept at room temperature, and served the same day, but it can be refrigerated, uncovered, up to 1 day; bring to room temperature before serving.

Steps:

• Preheat oven to 350 degrees. Butter a 9-inch square baking dish. Line bottom with parchment paper; butter parchment. Dust with flour, and tap out excess; set aside. Sift together flour and cornstarch into a small bowl; set aside.
• Put yolks, vanilla, and 1/2 cup sugar into the bowl of an electric mixer fitted with the whisk attachment. Beat on high speed until thick and pale, about 3 minutes. Transfer to a large bowl.
• Put egg whites and salt into the clean bowl of an electric mixer fitted with the clean whisk attachment. Beat on medium speed until soft peaks form, about 3 minutes. With mixer running, add remaining 1/4 cup sugar in a slow, steady stream. Continue beating until stiff, glossy peaks form, 2 to 3 minutes.
• Using a rubber spatula, fold egg white mixture into the yolk mixture. Fold in reserved flour mixture in 3 batches. Transfer batter to prepared pan; smooth top with an offset spatula.
• Bake until a cake tester inserted into center comes out clean, about 25 minutes. Let cool completely in pan on a wire rack. Turn out cake onto rack. Cake can be wrapped well in plastic and stored at room temperature up to 2 days.
