PASSION FRUIT SWISS MERINGUE BUTTERCREAM

• In the heatproof bowl of an electric mixer set over (but not touching) simmering water, combine the egg whites and sugar. Cook whisking constantly until sugar has dissolved and the mixture is warm to the touch (about 160 degrees).
• Switch to the paddle attachment. With mixer on medium-low speed, add butter, several tablespoons at a time, beating well after each addition. (If frosting appears to separate after all the butter has been added, beat on medium-high speed until smooth again, 3 to 5 minutes more.) Beat in vanilla. Beat on lowest speed to eliminate any air bubbles, about 2 minutes. Using a rubber spatula, gently fold in passion fruit curd until smooth.

GENOISE WITH PASSION FRUIT SWISS MERINGUE BUTTERCREAM

Steps:

• Preheat oven to 350 degrees with rack set in the lower third. Spray a 9-by-3-inch round baking pan with nonstick cooking spray; line pan with a parchment paper round and spray again. Set aside.
• In a small saucepan, melt butter over medium-high heat until nut-brown in color, about 8 minutes. Remove pan from heat and pour butter into a large bowl, leaving any burned sediment behind; stir in vanilla and keep warm (110 to 120 degrees).
• Lightly whisk together eggs and sugar in the bowl of an electric mixer; set mixer over (but not touching) simmering water and heat, whisking constantly, until lukewarm to the touch. Transfer bowl to electric mixer fitted with the whisk attachment and beat on high speed until light, airy, and quadruple in volume, at least 5 minutes. Whisk 1 cup egg mixture into warm melted butter mixture; set aside.
• Sift together flour and cornstarch. Gently and quickly fold half the flour mixture into remaining egg mixture until all the flour is absorbed. Repeat process with remaining flour mixture. Fold in butter mixture to combine and transfer to prepared baking pan.
• Transfer pan to oven and bake until golden brown and starts to shrink slightly from the sides of the pan, 20 to 30 minutes. If possible, avoid opening the oven door until cake has baked at least 30 minutes, as cake is fragile and may fall. Remove cake from oven and unmold immediately onto a wire rack to cool. Let cool completely before cutting into layers and frosting with buttercream.

GENOISE WITH BUTTERCREAM-ITALIAN MERINGUE

Steps:

• To make an Italian meringue, combine 3 1/2 pounds of sugar with 1 cup water in a large, heavy saucepan and heat over high heat until the syrup reaches a temperature of 240 degrees F on a candy thermometer. When syrup reaches a boil, watch carefully, as the temperature can escalate quickly.
• Meanwhile, in the bowl of an electric stand mixer, whisk the egg whites, the remaining 1 pound of sugar, and the cream of tartar to medium peaks. Once the syrup has reached 240 degrees F, start to drizzle the hot sugar syrup into the meringue while the beaters are running. Continue until all of the syrup is used and then continue to whip the meringue until it cools to room temperature.
• Slowly add in the softened butter; the mixture will tend to curdle. Continue to mix until all of the butter has been incorporated; the buttercream will eventually come together, becoming a smooth mixture in the end. Make sure to scrape down the bowl from time to time while mixing. Divide the mixture into 2 large sheet pans, cover securely, and refrigerate until ready to use.
• Make the cake:
• Lightly spray a size 400 hotel pan or large sheet pan with non-stick cooking spray and then line with parchment paper; set aside. Preheat the oven to 400 degrees F.
• Sieve the cake flour at least twice and set aside. Cream the eggs and sugar in a mixing bowl, beating until a pale yellow color. Gently fold in the cake flour. When this stage is almost completed, fold in the melted butter. Spread the genoise batter onto the prepared sheet pan. Bake for 10 to 12 minutes or until a toothpick inserted into the center of the cake comes out clean. Cool cake in the pan for 10 to 15 minutes, and then remove to a rack to cool completely before frosting.
• While cake cools, make a simple syrup by combining 1 cup sugar and 1 cup water in a heavy saucepan over high heat; bring to a boil and then remove from the heat and let cool.
• Assembly:
• Cut the cakes into 4 equal pieces so that they will fit perfectly on top of each other. Brush the bottom cake layer with simple syrup and then brush it with framboise. Brush a thin layer of raspberry marmalade on top and then apply a layer of the buttercream-Italian meringue. Repeat 2 more times. For the fourth and final cake layer, brush it with simple syrup and then framboise, but do not apply the marmalade. Frost the top and the sides of the cake, smoothing it out until perfect.
