Italian Rainbow Cake Recipes

Steps:

• Make the ganache: Place the chocolate in a medium bowl. Bring the cream and 1/2 teaspoon salt to a boil in a small saucepan, then pour over the chocolate. Shake the bowl so the chocolate is fully submerged in the cream, then let stand 1 minute. Using a small rubber spatula, slowly stir the chocolate and cream in the center of the bowl until it forms a shiny, smooth ganache. Cover the ganache with plastic wrap and let stand in a cool place in your kitchen until it is thick like pudding, but still pourable and spreadable, up to 2 hours. (See Cook's Note about timing.)
• Preheat the oven to 350 degrees F. Cut three 8-inch circles out of parchment paper. Using 2 tablespoons butter, grease and flour three 8-inch round cake pans and line each pan with a round of parchment paper.
• Whisk the flour, baking powder and the remaining 1/2 teaspoon salt in a medium bowl until evenly combined. Combine the sugar and remaining 14 tablespoons butter in the bowl of a mixer and beat on medium-high speed until pale and fluffy, about 3 minutes. Add the almond filling, lemon juice and almond and vanilla extracts and beat until smooth. Add the eggs one at a time, beating well after each addition. Add the flour mixture, then stir with a rubber spatula until the batter is combined.
• Divide the batter equally among 3 bowls. Add the green, yellow and red food colorings to the batter in their separate bowls, then stir the colorings. Scrape each batter into a prepared cake pan and smooth the top with a small offset spatula or rubber spatula. Bake until the cakes are lightly browned and a toothpick inserted in the middle of each cake comes out clean, 20 minutes.
• Transfer the cake pans to a wire rack and let cool 15 minutes. Invert the cakes onto the rack, remove the cake pans and discard the parchment paper rounds. Let the cakes cool completely, about 30 minutes. Flip the cakes right-side up and trim the top of each cake with a serrated knife so that it is flat, if necessary.
• Place the green cake on a cake stand and spread 1/4 cup jam evenly over the top. Place the yellow cake over the green and spread the remaining 1/4 cup jam evenly over the top. Place the pink layer on top, then loosely wrap the cake in plastic wrap and refrigerate for 30 minutes.
• Unwrap the cake and scrape the ganache on top (the ganache will be the consistency of thick pudding). Using an offset spatula, spread the ganache evenly over the side and top of the cake, leaving a slightly thicker layer on top. Once the ganache is smooth all around, drag the tines of a fork in a wavy pattern across the top of the entire cake. Refrigerate the cake to set the ganache, about 30 minutes. Allow the cake to come to room temperature before serving.

Steps:

• Cut the cookies to form 1-by-1-by-1/2-inch squares. Line a 9-inch springform pan with plastic wrap. Arrange the cookie squares all the way around the sides of the pan with the color lines running perpendicular to the bottom of the pan. Repeat with an additional ring of cookies above the first ring, lining up the colors as much as possible, so the cookies come 2 inches up the sides of the pan and almost completely cover them.
• Lay one cookie square in the middle of the bottom of the pan. Arrange a second cookie square next to it, with the color lines perpendicular to the color lines in the first cookie. Continue arranging cookie squares to create a parquet floor pattern. Fill the bottom of the pan with cookies, cutting some to fill in any odd-shaped areas. Chill until cold, about 30 minutes.
• Combine the chocolate and oil in a microwave-safe bowl and microwave in 30-second intervals, stirring between each, until melted, about 2 minutes. Using a pastry brush, coat the cookies on the bottom and sides with a thin layer of chocolate. Chill until set, about 5 minutes.
• Spread one of the pints of vanilla ice cream in an even layer over the chocolate-coated bottom cookies. Freeze until hard, about 1 hour. Spread the chocolate ice cream in an even layer over the vanilla. Freeze until hard, about 1 hour. Spread the remaining pint of vanilla ice cream in an even layer over the chocolate ice cream. Cover with the remaining cookie pieces. Freeze until solid, 6 hours to overnight.
• When ready to serve, invert the cake onto a plate so the bottom layer of cookies is on the top. Remove the pan and peel off the plastic wrap. Cut with a hot dry knife.

Steps:

• Arrange 2 racks in the center of the oven and heat to 350 degrees. Make room in your refrigerator for 1 half-sheet pan. Grease 3 (13-by-9-inch) baking pans or quarter-sheet pans with cooking spray or a little oil, then line with parchment or wax paper. (This helps the paper stay in place.) Spray or oil the parchment.
• Combine the flour and salt in a medium bowl. In the bowl of a standing mixer (or with a hand mixer), or in a large bowl if using an electric hand mixer, break up the almond paste using a fork or your fingers. Add butter, sugar, egg yolks and almond extract. Using the paddle attachment, beat on high until light and fluffy, about 5 minutes, scraping down the bowl halfway through. Turn off the mixer, add a third of the flour and salt, then beat on medium-low until just combined. Repeat with another third, scraping down the sides of the bowl as needed, and continue until all the flour is added and incorporated. Transfer batter to a large bowl. Rinse and dry the mixing bowl.
• Add egg whites to the mixing bowl and beat on high speed with the whisk attachment until stiff peaks form, 30 to 45 seconds. Fold the egg whites into the batter until just combined.
• Remove one-third of the batter to one of the prepared pans. Use an offset spatula to evenly spread the batter in the pan all the way to the edges. (This can get a little tricky, but have patience and take your time. The oil on the pan should help hold the paper in place, but if you're having trouble, hold the paper in place with one hand while you spread with the other.) Remove another one-third of the batter to a medium bowl and add a couple drops of green food coloring. Stir until blended, and add more to reach your desired shade. Transfer green batter to a prepared pan and spread evenly. Add a couple drops of red food coloring to the remaining batter, stir to combine, add more as needed, then transfer to the last pan and spread evenly. Firmly tap each pan on the countertop to release air bubbles.
• Bake for 10 to 11 minutes, rotating pans halfway through, until the edges are barely browned, the tops are just set, and a toothpick inserted into the center comes out clean. Immediately slide cakes from the pans onto racks using the parchment paper. Cool completely.
• Using the parchment paper, slide the green cake onto a half-sheet pan. In a small saucepan, heat preserves over medium until loose, then strain through a fine mesh sieve. Spread half of the preserves over the green layer, going all the way to the edge. Carefully flip the uncolored layer on top (use a large offset spatula to help), and remove the parchment paper. Spread with the remaining preserves. Top with the red layer and remove the parchment paper. Cover with plastic wrap and place another rimmed baking sheet on top of the cookies. Transfer to the refrigerator, then top with heavy cans so the weight is evenly distributed. Refrigerate overnight.
• Melt half of the chocolate in a double boiler or in the microwave in 30-second bursts. Using an offset spatula, spread the chocolate on the top and to the edges, then refrigerate until firm, about 30 minutes. Melt the remaining chocolate. Place a piece of parchment or wax paper on a cutting board, then place on top of the cake and invert the cake onto the board. Spread the bottom with the remaining chocolate. Let cool for a few minutes, then use the tines of a fork to draw waves in the chocolate and add sprinkles, if desired. Refrigerate until almost firm, but still slightly soft, about 5 to 10 minutes. (If you wait until the chocolate is fully set, the chocolate will crack when you cut.)
• Run a sharp knife under hot water, dry, then trim the edges and save for snacking. Cut the cake into 1-inch squares, running the knife under hot water and drying between cuts. Return to the refrigerator to set completely. Store in the refrigerator in an airtight container with wax paper between layers. Allow to come to room temperature a bit before serving.

Steps:

• Preheat oven to 375°. In a large bowl, beat eggs and sugar 2-3 minutes or until thick and lemon-colored. Gradually add almond paste; mix well. Gradually add flour, butter, salt and extract., Divide batter into thirds. Tint one portion red and one portion green; leave remaining portion plain. Spread one portion into each of three well-greased 11x7-in. baking dishes., Bake 7-11 minutes or until a toothpick inserted in center comes out clean and edges begins to brown. Cool 10 minutes before removing from pans to wire racks to cool completely., Place red layer on waxed paper; spread with 2 tablespoons jam. Top with plain layer and remaining jam. Add green layer; press down gently. , For glaze, in a microwave, melt chocolate chips and shortening; stir until smooth. Spread half over green layer. Refrigerate 20 minutes or until set. Turn over; spread remaining glaze over red layer. Refrigerate 20 minutes or until set. , With a sharp knife, trim edges. Cut rectangle lengthwise into fourths. Cut each portion into 1/4-in. slices.

Steps:

• Preheat the oven to 325°F. Line three 8-inch round cake pans with parchment paper and lightly coat with coconut oil. Set aside.
• In a medium bowl, whisk together the flours, potato starch, arrowroot, baking powder, baking soda, xanthan gum, and salt. Add 1 1/4 cups of the coconut oil, the agave nectar, applesauce, vanilla, the almond extract, if using, and the hot water. Stir with a rubber spatula until the batter is smooth.
• Divide the mixture evenly among 3 medium bowls. Add several drops of one food coloring to each bowl and mix until the color is evenly distributed and to your liking.
• Pour the batter into the prepared pans. Bake for 12 minutes, rotate, and bake until a toothpick inserted in the center comes out clean, about 15 minutes more. Let cool in the pans on a rack for 30 minutes. Run a knife along each cake's edges to remove it from the pan.
• To assemble, place the green cake layer on a serving plate. Spread the raspberry preserves over it. Place the yellow cake layer on top of it. Spread with the apricot preserves. Top with the red cake layer and pour the chocolate sauce on the top and on the sides, spreading it evenly over the entire cake with a rubber spatula.
• Chill the cake for 20 minutes to harden chocolate glaze.

Steps:

• Preheat the oven to 400 degrees F (200 degrees C). Grease six 9-inch round cake pans and dust with flour.
• Sift together the flour, baking powder, and baking soda.
• Beat 3/4 cup plus 2 tablespoons butter, milk, sugar, egg whites, and vanilla extract in a large bowl with an electric mixer until smooth. Stir in flour mixture and mix until just combined.
• Divide cake batter evenly between 6 bowls. Mix in different food coloring to each bowl, creating 6 different colored batters. Start with just 1 to 2 drops of food coloring in each bowl, then mix; you can always add more.
• Bake each cake in the preheated oven, until a toothpick inserted in the center comes out clean, 15 to 20 minutes. Set aside to cool.
• Beat cream in a chilled glass or metal bowl with an electric mixer until stiff peaks form. Stir together confectioners' sugar and mascarpone cheese in a separate bowl, then fold gently into the whipped cream until smooth.
• Spread frosting on each layer of cooled cake, placing one on top of the other. Cover the top and sides with the remaining frosting. Refrigerate for 2 hours before serving.
