Rainbow Cake

rainbow candy cakeWe started with 2 butter cake mixes made up into a quarter of a slab. We made up a light blue buttercream frosting, iced the cake then placed smarties grouped into their different coloures for the rainbow. We then placed the coloures on making sure the next row of smarties was slightly raised over the previous layer for a more 3d effect (so work from the outside of the rainbow to the inside of it you can do one or two layers of the same colour). We then placed broken up marshmallows (or small marshmallows) over the ends for clouds. Last of all, we cut up different coloured fruit sticks to make the flowers and then green decorating gel for the stems and a white dot of gel in the middle of the flower.

Serena's Care Bear Inspired Rainbow Cake

serena's care bear inspired rainbow cakeEach tier of Serena's Care Bear-inspired cake was a different flavor of cake (strawberry, chocolate, and vanilla.) The tiers were iced with ganache before covering them with fondant.

The topper (rainbow, clouds, star, and "5") were made with gum paste, and the remaining decorations were made of fondant.
