Recipe Summary Rainbow Layer Cake

This is more of a recipe for the design of the cake as it uses box cake. I cannot take credit for this awesome idea; found the idea for the rainbow cake and the recipe for the filling both online. I have used gum balls, Swedish Fish®, and M&M's® to decorate the border.

Ingredients | Treasure Chest Cake Design

30 ½ ounces white cake mix with pudding (such as Pillsbury Moist Supreme®)

6 eggs

2 ½ cups water

⅔ cup vegetable oil

5 drops red food coloring, or as desired

5 drops yellow food coloring, or as desired

5 drops green food coloring, or as desired

5 drops blue food coloring, or as desired

5 drops orange food coloring, or as desired

5 drops purple food coloring, or as desired

1 pound cream cheese, at room temperature

1 ½ cups butter, softened

1 tablespoon fresh lemon juice

1 teaspoon vanilla extract

¾ pound powdered sugar

1 pint heavy whipping cream

1 cup powdered sugar, or to taste

½ teaspoon vanilla extract

Directions

Preheat the oven to 350 degrees F (175 degrees C). Grease two 8-inch round cake pans.

Combine cake mix, eggs, water, and oil together in a large bowl. Beat using an electric mixer on medium speed for 2 minutes.

Split the batter into 6 different bowls and add a different food coloring to each bowl. Pour about 1 cup of each of the batters into the first pan in this order: red, orange, yellow, green, blue, and purple, right on top of one another in the center of the pan. Pour about 1 cup of each batter in the same manner into the second prepared pan in reverse order: purple, blue, green, yellow, orange, and red; you do not need to swirl the colors around at all.

Bake in the preheated oven until a toothpick inserted into the center of the cakes comes out clean, 34 to 38 minutes.

While cakes bake, beat cream cheese, butter, lemon juice, and vanilla extract for filling together using an electric mixer. Beat in powdered sugar until combined.

Beat heavy cream for frosting using an electric mixer until almost stiff; add powdered sugar and vanilla extract. Beat until cream holds peaks.

Remove cakes from the oven and let cool completely in a refrigerator, about 30 minutes.

Spread filling on the top of the bottom cake layer; top with the top layer of cake. Frost and decorate as desired. Keep cake refrigerated.

You can also make this in two greased 9-inch round cake pans. Be sure to bake according to individual package instructions.

To make orange= 2 drops red and 3 drops yellow food coloring several times. For purple- I actually used a purple from a neon box of food colors, but you can also mix blue and red.
