Ingredients
Creating a vibrant rainbow layer cake requires a few key ingredients to bring together the colorful layers and the smooth buttercream frosting. Let’s take a look at what you’ll need for this delightful dessert.
For the Cake Layers
- 2 ¾ cups all-purpose flour
- 1 ½ teaspoons baking powder
- ¼ teaspoon salt
- 1 ½ cups granulated sugar
- 1 cup Land O Lakes Butter (softened)
- 4 large eggs
- 1 tablespoon vanilla extract
- 1 ¼ cups buttermilk
- Gel food colors (violet, blue, green, yellow, orange, red)
- 2 cups unsalted butter (softened)
- 8 cups confectioners sugar
- ¼ cup heavy cream
- 2 teaspoons vanilla extract
- ½ teaspoon salt
These carefully selected ingredients will ensure that your rainbow layer cake turns out moist, flavorful, and beautifully colorful.
Necessary Equipment
To create a perfect rainbow layer cake, having the right equipment is crucial. Here are the recommended cake pans and coloring tools you’ll need:
Recommended Cake Pans
For this rainbow layer cake recipe, I recommend using 8-inch cake pans for optimal results. These slightly less common pans provide additional height to the cake layers, giving a more impressive appearance. If you only have 9-inch pans, they can also be used; just be mindful of potential variations in baking times and results.
Coloring Tools
Coloring the cake layers beautifully is essential for achieving a vibrant rainbow effect. For this recipe, you’ll need a variety of gel food coloring in red, orange, yellow, green, blue, and purple hues. You can also add optional pink coloring for an extra touch of charm. Using quality gel colors ensures that the cake layers come out bright and visually stunning.
Preparation
Preparing the Rainbow Layer Cake involves steps to ensure the cake batter is colorful and vibrant. Let’s dive into the details to create a visually stunning dessert.
Preparing the Cake Batter
To begin, preheat the oven to 350°F. Line the cake pans with parchment rounds and grease them lightly. Mix the dry ingredients like flour, baking powder, sugar, and salt in a stand mixer. Incorporate the wet ingredients gradually while mixing until the batter is smooth and fully combined. Divide the batter evenly into six bowls to add the colorful food gel, creating distinct rainbow hues.
Coloring the Batter
As you have divided the batter into six bowls, it’s time to add the food coloring. Start with a few drops, mix well, and gradually add more until you reach the desired intensity of each color. Remember to keep the colors vibrant and bold for a visually appealing rainbow effect in your cake layers. When all the batters are colored, pour each one into the prepared cake pans and bake until they are cooked through.
Baking Instructions
Portioning the Layers
To create perfectly even and vibrant rainbow layers, divide the cake batter equally into six separate bowls. This ensures each layer receives the right amount of colorful gel food coloring for a stunning and uniform rainbow effect.
Baking Each Layer
Bake the divided and colored batter in well-prepared cake pans until the layers are cooked through. Look for signs like the cake pulling away from the sides and the tops springing back when touched to know they are done. Let the layers cool completely before attempting to frost them for a flawless finish.
Assembling the Cake
Layering and Frosting
To assemble the rainbow layer cake, start by placing the purple cake layer bottom-side up on a serving plate. Frost the top with a quarter cup of white frosting. Continue by layering the blue, green, yellow, orange, and red cake layers in that order, frosting with a quarter cup of white frosting between each layer. Once all the layers are in place, frost the outside of the cake with the remaining white frosting. This thin layer of frosting will allow the cake to be slightly visible through it. After frosting, refrigerate the cake for about 30 minutes to set – this step is known as a “crumb coat” and helps prevent crumbs from interfering with the final frosting.
Decorative Ideas
Enhancing the visual appeal of your rainbow layer cake adds a pleasant touch to your baking creation. Let’s explore some decorative ideas to make your rainbow layer cake even more eye-catching!
Creating a Rainbow Effect
To achieve a stunning rainbow effect on your cake, consider using a piping bag with a large star tip. Start by adding all the vibrant colors of the rainbow to your piping bag, creating a beautiful swirl of colors. As you pipe frosting shells around the cake, give the piping bag a slight turn after each shell to create a mesmerizing rotating look of colors on your cake. This simple technique will give your rainbow layer cake a delightful and colorful finish.
Additional Garnishes
For an extra touch of whimsy and fun, consider decorating your rainbow layer cake with rainbow sprinkles or pastel candy quins. These decorations not only add a pop of color but also enhance the festive appeal of your cake. Get creative with your choice of decorations to personalize your rainbow layer cake for special occasions like birthdays, celebrations, or simply to spread joy with a vibrant dessert that is as delightful to look at as it is to eat.
Storing the Cake
After creating this delightful rainbow layer cake, it’s essential to know how to store it properly to maintain its freshness and flavor. Here are the guidelines for refrigerating and freezing this colorful treat:
Refrigeration Guidelines
Once the rainbow layer cake is baked and assembled, you can store any leftovers by covering the cake and leaving it at room temperature for up to 3 days. If you prefer to keep it longer, refrigerating the cake is an option. Simply cover it and place it in the refrigerator, where it can be stored for an extended period while retaining its taste and texture.
Freezing and Thawing Instructions
If you want to freeze the rainbow layer cake to enjoy later, either freeze the individual cake layers before assembling or the entire assembled cake. To freeze the cake layers, ensure they are completely cool, then wrap each layer thoroughly in plastic wrap and aluminum foil before placing them in the freezer. The wrapped cake layers can be stored in the freezer for up to 3 months. If you prefer to freeze the whole cake, tightly wrap the assembled cake in plastic wrap and foil before freezing. Additionally, if you have leftover cake slices, you can flash-freeze them individually on a lined baking sheet, then wrap them in plastic wrap for future enjoyment.
With these simple guidelines, you can enjoy your rainbow layer cake at its best, whether freshly baked, refrigerated, or frozen for later indulgence.
