Hello friends, I hope you are faring well in this sweltering heat wave. Today’s post is about a birthday cake I prepared for a co-worker’s daughter’s 4th birthday. She was having a rainbow themed party and we must have both been on the same wavelength because we both knew if I was going to make a cake, there was only one it could be.

The Rainbow-Doodle Birthday Cake created by Rosie Alyea over at Sweetapolita. The inspiration cake was a six layer creation covered in fondant and decorated by her daughter using food coloring markers. My co-worker asked if I could not only make the cake, but replicate the doodling of a 4-year-old. I should also mention at this point that until this request came in, I have been avoiding using fondant like the plague. I’m not going to lie, it scared me. I had fears of it breaking at the edge, falling, dragging, condensation, and the horrors I heard about the taste had me uneasy. Not to mention that I was apprehensive about the effect the weather was going to have on the cake because the party was outside. In June. But, how could I disappoint a little kid, so I forged ahead and was up for the challenge!

Using Sweetapolita’s cake for inspiration, I created a 6 layer ROY G BV (no “I”) from my favorite butter cake recipe coloring it with AmeriColor Electric Ultra Bright Colors and covered it in fluffy homemade buttercream.
Then I mentally prepared myself to win the battle of the fondant. Thankfully, I did enough research online to try Satin Ice in White/Vanilla. Wow, what a product! Not only was the taste on par with a vanilla Tootsie Roll, the texture was amazing and with minimal effort I had it rolled out to a 25″ circle, had it onto the cake and smoothed out in a matter of minutes. I was totally surprised at the ease of it. However, I am not going to lie- I watched hours of online video and did have to psych myself into it.
Once the fondant was on, the fun started! Using Americolor Food Color Markers, I used the final Sweetapolita image as a guide for the top of the cake.
Since I wasn’t able to see all the sides, I created some of my own doodles and even drew a little girl holding a birthday balloon. I also left a space at the top for the birthday girl to write in her own name.

This is SO cute — and so labour-intensive! Fondant is difficult stuff, but I think you’ve done a really good job with it. That’s one lucky little girl, getting a 6-tier rainbow cake for her birthday.
Thanks! Have a great day
That looks awesome… but a lot of work! I would love to try fondant too, so maybe I will, you have inspired me
Thanks! It wasn’t too bad cause I did it in steps
Best of luck and let me know if you attempt the fondant!
