As my little girl is all about rainbows, but not a huge cake lover, I decided to make a rainbow using cupcakes for her fifth birthday party. Now, I am not a crafty, creative or talented mom in any way, but, I thought it wouldn’t be too complicated.
And really it wasn’t so bad, just a little laborious with the frosting.
I don’t have pictures of the process because it was all-consuming and I had food coloring all over me! My fabulous friend and neighbor lent me her MINI cupcake pans and she had a set of Wilton food coloring which made this task so much easier. I also purchased a cupcake pen which was a huge time saver.
So here’s what you need:
food coloring gels
mini cupcake pans — the more the better
1 regular cupcake pan
2 boxes white cake mix (I used Pillsbury)
2 cups water
6 eggs
2/3 cup oil
2 cans vanilla frosting
mini marshmallows
large foam board
I bought a large foam board as the base and glued blue poster board to it for the sky effect. I mixed up both cake mixes at the same time and started making the mini cupcakes, planning for about 96 minis and 1 big cupcake for the sun. I had plenty of muffins left over. I used the gel generously to make the colors pop and was able to do all the colors splitting up just 2 cans of white frosting. I planned ahead with an idea of how many cupcakes I would need and for which color. Here is the breakdown:
18 RED, 15 ORANGE, 13 YELLOW, 11 GREEN, 9 BLUE, 6 PURPLE, 18 WHITE
For the white cloud cupcakes I did 9 cupcakes on each side. Each cupcake had 8 marshmallows.
For the sun I mixed the leftover orange and yellow frosting to make an orange-yellow sun. I frosted the surrounding “sun rays” (6 cupcakes) in the same color.
I was completely wowed with the end result. And my rainbow lover? She stared at it for about 3 hours this morning until her party started…

This may be my best mom accomplishment ever! Have you ever seen anything like it?!



I think the rainbow cake looks fantastic. Nice job! She will always remember the day you made this for her!
thank you and I certainly do hope it’s a fond memory for her.
this is brilliant and i’ve printed it out just i case i’m feeling energetic enough to give it a try for my girl’s 7th birthday in september as she is a llllll about rainbows too!
cool keep me posted!
Love it, pinned it to my creative board! I’ve lately pinned into the night…..I’m an idea person…..so this is a new favorite of mine…..also do your kids play Cut the rope or Where’s my water? Both very educational and fun..I recommend…James gets to play them about 15 min a day…such a treat!
thanks Melinda! I still can’t believe I pulled it off! I’m not familiar with those games but would love to hear more…
