RAINBOW CAKE MOLD RECIPES

Steps:

• Make the cake: Heat oven to 325 degrees and place a rack in the center. Butter and line the bottoms of two 8-inch round cake pans with parchment paper. Butter the parchment. Flour the pans, coating the bottom and sides, then tap out any excess flour.
• In a medium bowl, whisk together flour, baking powder, baking soda and salt. In a small bowl, stir together milk and vanilla.
• In a mixer fitted with the paddle attachment, beat butter and sugar at medium-high speed until light and fluffy, 2 to 3 minutes. Reduce speed to low and, with mixer running, slowly add egg and whites and beat until smooth and creamy, 1 to 2 minutes. Scrape down bowl. Add half the flour mixture, then the milk mixture, then the remaining flour mixture, beating to blend after each addition. Scrape down bowl and blend once more. Remove bowl and use a spatula or spoon to mix in sprinkles by hand.
• Divide batter evenly between the pans and bake until the tops are just dry to the touch and a toothpick inserted into the center comes out clean, 20 to 25 minutes. Rotate the pans halfway through baking.
• Transfer pans to a wire rack and let cool completely, at least 4 hours, before turning out.
• Make the frosting: In a mixer fitted with the paddle attachment, beat cream cheese, butter and salt together at medium speed until light and fluffy, 2 minutes. Reduce speed to low and, with mixer running, slowly add sugar and beat until smooth. Beat in vanilla just until incorporated. Taste frosting; you should be able to taste the cream cheese and a little bit of saltiness, as well as the sweetness. If desired, add more salt or sugar. Keep refrigerated.
• Turn cooled cakes out of pans. Using a bread knife, cut off any domed or uneven parts of each cake to make flat surfaces. Place one of the cakes on a platter or a cake stand, cut side up. Using an offset spatula, frost the top. Stack the other layer on top, cut side down. Place remaining frosting on top of the cake and, working from the center outward, frost the top and sides of the cake.
• Place a baking sheet under the platter or cake stand, to catch any fallen sprinkles. Sprinkle the top with a layer of sprinkles. Toss remaining sprinkles at the sides of the cake, or press handfuls of sprinkles gently up the sides to make a thicker coating. Gather fallen sprinkles and repeat until coated to your liking.
• Refrigerate cake 30 minutes or longer to set. Serve cool.

Steps:

• Preheat the oven to 325 degrees F. Line three 13-by-9-inch baking pans with either parchment paper or greased aluminum foil.
• In a food processor, pulse together the butter, confectioners' sugar and almond paste until pale yellow and fluffy. Continue to pulse while adding the eggs one at a time, then the vanilla extract. Add the flour and process until a smooth dough forms, stopping occasionally to scrape the sides and corners of the bowl.
• Remove the dough and divide into 3 even pieces. Place one piece back into the processor with a dab of red gel food coloring, and pulse until combined. Repeat with another piece and a dab of green food coloring. 
• Spread the red, green and plain doughs in the prepared baking pans, and bake until light and springy to the touch, about 15 minutes. Allow to cool completely in their pans, about 1 hour.
• Remove the cookie layers from their pans, reserving 1 pan to use as a mold. Place the apricot and raspberry jams in separate bowls or mugs and microwave until loose, about 1 minute. In another bowl, toss the chocolate chips with the corn syrup and oil and microwave in 30-second spurts, stirring with a fork in between, until a shiny glaze is formed.
• Place the green layer in the pan, then spread a thin layer of raspberry jam over it. Next, add the white layer, then repeat the process with the apricot jam. Top with the red layer, then spread the chocolate glaze across the top. Place in the refrigerator until the chocolate hardens, then wrap in plastic and allow to set for another hour, refrigerated.
• Place a cutting board on top of the pan, invert it, and unmold the cookies. Using a sharp knife, cut the cookies lengthwise into 4 long pieces, then cut across in 1/2-inch intervals. These keep, well-wrapped at room temperature, 5 days.
