Storing: A fondant covered cake can be kept in a storage container at room temperature for up to 3 days or refrigerated for up to a week (depending on your choice of fillings and/or toppings). Pour each colour into one of the prepared tins and bake for approximately 25 minutes, turning after 18 minutes so they colour evenly.

Layer the colors in your prepared 8-inch cake pans by adding a spoonful of each different color in the center (the colors will spread and push out to form the rainbow layers). In your prepared 8-inch cake pans, layer the colors by adding a spoonful of each color into the center. When ready to eat, thaw it in the fridge overnight then set it out to come to room temperature before you slice and serve. Scrape the different batters into the tins, trying to spread and smooth as much as possible – but try not to waste a drop of the batter – a rubber spatula will help you. Put 2 spoons of the buttercream on the top of the cake, then spread the buttercream towards the edges and down the sides with a palette knife.

Gel food coloring is easier to work with when coloring cake batter, icing, and frosting and is also easy to find at the locations mentioned above. Unless you’re making the optional pink layer, repeat one more time to get 6 sponges, all of different colours.

Dreams come true, it's time for a Rainbow High Dolls Birthday party and your cake will look the cutest with this Rainbow High cake topper. No matter where you take this cake, it is always a crowd pleasing favorite with it's bright colors and fantastic flavors!

Everyone will be so impressed that this beautiful cake was made by hand and not purchased at the bakery.

I was a little nervous as even though I am no means an expert, I've never added the wet ingredients as they are to the dry.Divide the batter equally between 6 medium-sized bowls and add dashes of each of the food colourings. Level each of the cake rounds, then spread a small amount of buttercream beneath where the center of the cake will sit to hold it in place.

In a large mixing bowl or the bowl of your stand mixer, add all of the dry cake ingredients (2 ¼ cups all-purpose flour, 1 ⅓ cups sugar, 3 teaspoons baking powder, and ½ teaspoon salt) and mix them together. We developed a brand new Madagascan vanilla seed cake recipe to make sure that our Rainbow layer cake would be super moist and have that real authentic buttery vanilla birthday cake taste.Transfer the baked rainbow cakes to a wire cooling rack so they may cool completely before you decorate. Sift the icing sugar on top, bring the mixture together at a low speed, then beat at high speed for a few minutes until the mixture is pale and fluffy. Fun for everyone and perfect for any occasion, this easy marbled rainbow layer cake will be the hit of the party! My cake is topped off with a buttercream frosting crumb coat, then a layer of marshmallow fondant before we added more rainbow colored fondant polka dots!
