To make this 6 layer cake, you'll need the following:
* 2 boxes standard yellow cake mix (and required eggs, oil, etc.)
* Some kind of filling for between the layers (I used store-bought lemon which I mixed with fresh squeezed lemon juice and some cream to make it a bit smoother)
* Double batch of buttercream frosting (I included a fantastic recipe below)...you'll have leftovers you can freeze for later
* Single batch of marshmallow fondant (recipe for this included as well)
* Gel food colorings (red, orange, yellow, green, blue, and purple)
* 3 cake dowels (I prefer the wooden kind)
* 1 large cake cardboard circle
Mix the 2 boxes of cake mix and then separate evenly into 6 bowls. Add about 3 small drops of gel food coloring to each bowl and mix until color is even.
www.allrecipes.com) has a great recipe for marshmallow fondant which wasn't half bad! http://allrecipes.com/recipe/marshmallow-fondant/detail.aspx?event8=1&prop24=SR_Title&e11=marshmallow%20fondant&e8=Quick%20Search&event10=1&e7=Home%20Page
This was my first time EVER making fondant, and I'd be lying if I didn't admit it was by far the most challenging part of this cake. Making it at 10:00 night when I'm already tired probably wasn't one of my finer moves, and I definitely had that "oh crap" moment when I was convinced this blob of white goo was NEVER going to turn into what you see on professional cakes. I had to use quite a bit more butter and used more confectioners sugar to knead once I transferred the fondant out of the bowl and onto the counter. But overall, the instructions proved true and my fondant attempt was successful! Yay me:)
Separate fondant into 6 even parts, knead food gel color into each part (I used 3 drops per color), wrap and place in refrigerator to cool overnight. Yes...overnight.

After your crumb coat is done, place the cake back in the refrigerator to cool again before doing final layer of frosting. I had luck getting the frosting to look nice and smooth by using a scalding hot frosting spatula that I dipped in water to clean off between spreading.
Make whatever kind of decoration you want on the top. Lightly brush the cornstarch off the fondant with water and you're done!
I'll post some actual pictures from Gemma's little party soon too:)
