This oh so pretty pastel rainbow ruffle cake takes a little bit of time to put together, but the wow factor once it's finished is sooo worth it. You can use packet mix cake and frosting or whip up your own favorite recipes and then just follow the easy steps to make rows of ruffly sweetness.

The ingredients and equipment for this cake can be found at large craft and hobby stores, cake specialty stores and even on Ebay.

Ingredients and Equipment
3 boxes of white cake mix (or make your own using your favorite recipe)
Shop bought white Buttercream or Frosting (or make your own using your favorite recipe)
Rolled Fondant or Pettince 44 oz or 1300 grams *
Pink, violet, blue, green and yellow gel food color (I used Wilton)
Large rolling pin
cornflour (corn starch)
Small Rolling Pin
Large knife for trimming the cake
Small sharp knife
Cake smoothers X 2
Frilling tool - if you do not have a frilling tool a toothpick can be used for a similar result
Not stick flower molding mat
Small brush and water

*Fondant dries out really quickly - keep it in an airtight container or ziplock bag in between use and work really quickly. 

The night before decorating the cake color the fondant with the gel colors as follows: 8 oz (240 g)pink, 4 oz (120 g) violet, 4 oz l(120 g) light blue, 4 oz (120 g)light green and 4 oz (120 g) light yellow, the remaining 20 oz (580 grams)should remain plain white.

To color fondant knead until soft and then add the gel food color a drop at a time kneading well until the desired color is achieved. Store in an airtight container until ready to use.

Looks fabulous. I've never made a buttercream that needs refrigerating, so that's no problem!
Butter creams that require refrigeration will not be suitable for this cake. OH REALLY?!?! Thanks for making that the 2nd to last sentence of the entire instructable.
Hi - if you would like a totally buttercream rufflecake recipe (that can be refrigerated) check out this version on my blog - it's actually easier to make the buttercream ruffles and you can easily do it in pastel colours so it looks pretty similar to this fondant version.
