RAINBOW SPRINKLES LAYER CAKE

Steps:

• For the cake layers: Preheat the oven to 350 degrees F. Coat six 8-inch round cake pans with flour-based baking spray (or grease and flour pans).
• Sift the flour, baking powder and salt into a large bowl. Combine the milk and vanilla in a large liquid measure with a pour spout. Beat the butter in the bowl of an electric mixer on medium speed until smooth. With the mixer running, gradually add the granulated sugar and beat until the mixture turns pale and fluffy, about 3 minutes. Reduce the speed to low and add the flour mixture in 3 additions, alternating with the milk mixture. Begin and end with the flour. Mix until just combined.
• Beat the egg whites in a spotlessly clean bowl on high speed until stiff peaks form, about 5 minutes. Gently fold the egg whites into the batter in 3 additions.
• Place 2 cups of the cake batter in 6 separate bowls. Tint each bowl of batter with a different gel food color, so that you have a bowl of red, orange, yellow, green, blue and violet batter. Fold the color in well with a rubber spatula until no streaks of white cake batter remain.
• Spread the batter into the prepared pans and bake until a toothpick inserted in the center of the cakes comes out clean, about 20 minutes. Turn the cakes out onto wire racks to cool completely. When the cakes are cool, level the tops with a serrated knife or a cake leveler.
• For the Swiss meringue buttercream: Set a saucepan filled one-third full of water over medium-high heat and bring to a simmer.
• Whisk together the egg whites, granulated sugar and salt in a large heatproof bowl. Set the bowl over the simmering water and whisk until the mixture is hot to the touch and the sugar has dissolved (120 to 140 degrees F on a candy thermometer). Transfer the mixture to the bowl of an electric mixer fitted with the whisk attachment. Beat on low speed for 2 minutes. Increase to medium high until stiff peaks form. Continue beating at medium-high speed until the mixture is fluffy and has cooled (the mixing bowl should feel cool to the touch).
• Turn the mixer off and switch from the whisk attachment to the paddle. Turn the mixer to medium-low speed and add the butter a few cubes at a time, beating until well incorporated before the next addition (see Cook's Note). Add the vanilla extract. Beat on high speed until the frosting is thick and completely smooth.
• Frost the cake: Transfer 1 cup of frosting to a piping bag fitted with a small star tip; set aside.
• Top each cake layer with a small amount of frosting. Begin with the violet cake layer on the bottom, followed by the blue, green, yellow, orange and red. Cover the entire cake with frosting using an offset spatula and smooth the frosting with a bench scraper or frosting smoother. Place the cake in a large dish and use a cupped hand to press on the rainbow sprinkles, allowing the excess to fall back into the dish. Repeat until the bottom two-thirds of the cake is covered with the sprinkles. Using the reserved frosting in the piping bag, pipe stars around the top edge and center of the cake, and around the bottom edge of the cake. Decorate each star on the top edge of the cake with alternating colors of the round candies. Scatter rainbow nonpareils over the bottom edge. Add more rainbow sprinkles to the top center of the cake.
• For the marshmallow fondant bunting: Combine the marshmallows and 1 1/2 teaspoons water in a large microwave-safe bowl. Microwave for 30-second intervals at 100% power, stirring in between each, until melted and smooth, about 1 minute.
• Add 1 cup of sifted confectioners' sugar to the melted marshmallow and stir to combine. When the first cup is thoroughly mixed in, add the second cup of confectioners' sugar. Stir well until stiff. Grease a work surface with the vegetable shortening and transfer the fondant from the bowl to the greased area. Knead well until smooth and pliable. The fondant should not be sticky and it should hold its shape firmly when rolled into a ball. If the ball relaxes and loses its shape, knead in more confectioners' sugar a little at a time.
• Roll the fondant into a ball and cut into 6 even pieces. Tint each ball with the food colors so that you have one of each: red, orange, yellow, green, blue and violet. (Wear gloves during kneading to avoid staining hands.)
• Roll out each piece of fondant to 1/8 inch thickness on a piece of parchment paper. Use a 1 1/2-inch triangle cutter to stamp shapes from each piece of fondant.
• Place the triangles end-to-end in a swag design around the top edge of the cake, in rainbow color order (red, orange, yellow, green, blue, violet). If the pieces do not naturally stick to the frosting, add a small dot of water to the backs of the triangles to adhere them to the cake.
• Serve eye-popping slices of rainbow cake to delighted guests. If there are leftovers, cover the cake loosely with plastic wrap and store at room temperature.

SPIROGRAPH CAKE

Steps:

• For the Spirograph® decor: Knead the fondant until smooth and pliable. If the fondant is sticky, knead in a little confectioners' sugar until the fondant is elastic and does not cling to your hands. Roll out the fondant between 2 sheets of parchment paper to 1/4-inch thickness using a rolling pin. Remove the top sheet of parchment paper and allow the fondant to stand until the surface is firm and dry. This can take 2 to 4 hours (and up to overnight), depending on the surrounding humidity of the room in which you're working. The fondant can be tested for readiness by attempting a Spirograph® design. Place the Spirograph® tools on top of the fondant and begin to draw using light pressure with a food color marker. If the tip of the pen sinks into the fondant, it is not dry enough to use and needs to stand longer. If the pen glides across the surface, then it's ready to use.
• Use the Spirograph® tools to practice drawing on a piece of copy paper before you begin drawing on the fondant. Choose your favorite designs to replicate on the fondant.
• Place the Spirograph® tools on the dry fondant and use the food color pens to draw designs onto its surface. Make various sizes and patterns. You'll need about 14 designs to cover the entire cake. Allow the drawings to dry for 10 minutes, then use the cookie cutters to stamp out the designs. Store the stamped-out circles in a single layer between 2 pieces of plastic wrap.
• For the chocolate cake: Preheat the oven to 350 degrees F. Spray three 6-inch round baking pans (or two 8-inch pans) with flour-based baking spray.
• Beat the butter and granulated sugar together in the bowl of an electric mixer. Add the oil; beat in the eggs 1 at a time, mixing well after each addition.
• Whisk together the cocoa powder, flour, baking soda and salt in a large mixing bowl. Add the flour mixture to the creamed butter mixture alternately with the sour cream, beginning and ending with the flour mixture. Add the hot coffee at the end and mix on low speed until just combined. Use a spatula to scrape down the bowl and mix again on low until the batter is smooth.
• Divide the batter evenly among the prepared pans, filling each pan no more than three-quarters full. Bake for 30 to 35 minutes, or until the cakes spring back when pressed in their centers. Turn the cakes out onto wire racks to cool. When the cakes are completely cool, level the tops using a large serrated knife or cake leveler
• For the buttercream frosting: Cream together the butter and confectioners' sugar on low speed in the bowl of an electric mixer. When the mixture is combined, increase the speed to high and whip until light in color, about 3 minutes. Turn the mixer off and add the vanilla extract and 1/3 cup heavy cream. Beat again until the frosting is light and fluffy, about another 3 minutes. Add additional heavy cream if the mixture is too thick to spread or pipe.
• Place 1 cup of buttercream in a medium bowl. Drape a damp towel across the bowl to prevent the frosting from drying. Set aside.
• Place the remaining frosting in a large piping bag. Use the buttercream to fill the cake layers and to apply a thin crumb coat to the outside of the cake. Use an offset spatula or bench scraper to even the frosting. Place the cake in the refrigerator to chill until the frosting is firm, about 30 minutes. Meanwhile, divide the reserved 1 cup of frosting into 3 parts in separate bowls and tint each portion with one of the 3 gel food colors.
• When the crumb coat layer is well chilled, apply a second layer of white frosting and even the edges of the cake with a bench scraper. Use an offset spatula to randomly place dabs of pink, orange and lavender tinted buttercream over the edges and top of the cake. Carefully scrape away some of the tinted frosting using a single motion with a bench scraper. The colors will smear and blend together, creating a watercolor effect. Add more color dabs of frosting and repeat the process as desired. Transfer the cake to the refrigerator to chill.
• When the cake is well chilled, apply the fondant Spirograph® designs to the sides of the cake using buttercream as an adhesive. Use leftover white buttercream to pipe small mounds of frosting on top of the cake; cover the buttercream with assorted sprinkles and nonpareils. Place 1 fondant Spirograph® design on top of the cake if desired.
