Extra Rich Vanilla Cake with Rainbow Frosting
No special tools or skills necessary! Extra Rich Vanilla Cake Recipe with Rainbow Frosting
By now it’s no secret that I have a thing for rainbows. Whether it’s a swirly rainbow cheesecake, a tie-died rainbow birthday cake, or rainbow chocolate chip cookies, I just can’t quit rainbows. I have even been known to snack on homemade rainbow granola.
Can’t.
Stop.
I love partnering with brands that I use and trust in my own home. So when McCormick asked if I would like to help celebrate their 125th birthday (!!!) I knew that I wanted to make them a unique rainbow cake.
They sent me their special anniversary edition Extra Rich Pure Vanilla Extract and I made a cake. Then I ate the cake all by myself. I didn’t even save them a piece. I am the worst friend.
I purposely used a boxed vanilla cake mix for this recipe so as not to scare anyone off. If boxed cake mix is against your religion you can make your favorite recipe from scratch. Just be sure to add in some extra rich vanilla extract- you only turn 125 once, right?!
Please note that you will need two boxes of cake mix for 3 thick cake rounds. You could spread 1 box between 3 rounds but there is a lot of frosting tucked inside this cake so I wanted the frosting-to-cake ratio to be just right. (You will have an extra cake round- I let my kids decorate that one while I worked on the rainbow cake.)
When it comes to the frosting you can use your favorite as well. Tint 1/2 cup of frosting red, orange, yellow, green, blue, and purple. Then spread the frosting in a bulls-eye pattern between your cake layers.
