This recipe yields an extra cake layer that can be reserved for another time. Wrap it tightly in foil, and freeze it for up to a month. Keeping the cake wrapped, defrost it at room temperature; then serve it with berries and whipped cream or ice cream.
Place one pan on each rack in oven, staggering pans so that one is not directly above the other. Bake cakes 25 minutes. Reverse position of pans. Bake cakes until tester inserted into center comes out clean, about 10 minutes. Cool cakes in pans 10 minutes. Line 2 cooling racks with kitchen towels. Cut around cakes to loosen; turn out onto towels. Cool completely. (Can be made 1 day ahead. Wrap in foil; store at room temperature.)
04Makes about 8 cups.
058 ounces good-quality white chocolate (such as Lindt or Baker’s), chopped
061/2 cup whipping cream
072 cups (4 sticks) unsalted butter, room temperature
081 cup egg whites (about 8)
092 1/4 cups sugar
102 1/2 teaspoons grated orange peel
112 teaspoons vanilla extract
12Stir white chocolate and cream in heavy small saucepan over low heat until melted and smooth. Cool to room temperature. Using electric mixer, beat butter in medium bowl until fluffy; set aside.
13Combine whites and sugar in large metal bowl. Set bowl over large saucepan of simmering water (do not let bottom of bowl touch water). Whisk until sugar dissolves and thermometer inserted into whites registers 160°F, about 3 minutes. Remove bowl from over water. Using clean dry beaters, beat meringue until cool, stiff and shiny, about 10 minutes.
14Beat butter, about 1/4 cup at a time, into meringue, blending well after each addition. If frosting looks curdled, place bowl over very low heat for 3 to 5 seconds to soften slightly. Remove from heat and beat until smooth. Repeat warming technique as necessary. Gradually beat in cooled white chocolate mixture, then orange peel and vanilla extract. Chill buttercream until beginning to firm, about 30 minutes.
151 cup seedless raspberry jam
166 cups (about) assorted fresh berries (raspberries; blueberries; blackberries, halved if large; and sliced strawberries)
17Cut each cake in half horizontally. Place 1 layer on 11-inch-diameter tart pan bottom or cardboard round. Spread with 1/2 cup jam, then 1 1/4 cups buttercream. Arrange half of berries atop buttercream, spacing about 1/2 inch apart. Press second cake layer atop berries. Repeat layering of jam, buttercream and remaining berries. Top with third cake layer (reserve remaining cake layer for another use).
18Spread 2 cups buttercream in thin layer over top and sides of assembled cake to anchor crumbs and smooth surface. Refrigerate cake on its base until crumb coat is firm, about 30 minutes.
19Spread 2 1/4 cups buttercream over top and sides of cake. Spoon remaining buttercream into pastry bag fitted with medium star tip. Pipe decorative border around top edge of cake. (Can be prepared 2 days ahead. Cover with cake dome and refrigerate.)
22Place cake with its base on platter. Fill top center of cake with berries. Melt jelly in heavy small saucepan over low heat, stirring constantly. Using pastry brush, brush warm jelly over tops of most berries. Let cake stand at room temperature at least 1 hour and up to 3 hours.
23Using long knife, cut cake into quarters. Cut each quarter into 6 wedges.
