I have a lot of fun creating rainbow-inspired cakes because it’s exciting to figure out different ways to incorporate the rainbow into or onto the cake. There are so many different ways to do it and the colors together always create such a beautiful cake! I can’t wait to see your take on these cakes and which one ends up being your favorite. 

Rainbow Cake Recipe #1: Rainbow Tutorial

My first rainbow cake recipe can actually have any cake flavor you prefer (green velvet would be a fun festive choice!) and then I used vanilla buttercream to cover it! I added some food coloring to make the different colors, then piped them onto saran wrap, carefully folded them, and placed them into the piping bag to prep them for piping the rainbows on the side of the cake. My original post HERE has step-by-step instructions on how to do this! 

Rainbow Cake Recipe #2: Rainbow Sherbet

My Rainbow Sherbet Cake comprises tender yellow cake layers, raspberry lime curd, and orange buttercream. I created this new recipe on a whim with my son Westin years ago when I had some leftover yellow cake layers. We raided the pantry to see what would be good together and we settled on the raspberry lime and orange flavors. As soon as I took the first bite it took me back to my childhood days when I would get rainbow sherbet ice cream at Baskin Robbins! 

Rainbow Cake Recipe #3: Green Velvet

This Green Velvet Rainbow Cake is a great choice if you’re wanting to impress your kids! I included a fun surprise on the inside of the cake and it was so fun to see my kids’ eyes glued to the cake as I cut the first slice and then see their reaction once they saw the surprise. I hid some gold coins in the middle, so it’s like the gold treasure at the end of the rainbow! Such a fun cake to make and definitely to share with my kids. I hope you enjoy this one as much as we did!

Funfetti has been a popular cake choice for generations and I can totally see why! It’s filled with such fun colors and tastes amazing. My version of Funfetti Cake is made up of light and fluffy vanilla cake layers, lots of sprinkles, and a whipped vanilla buttercream frosting. I’ve made some updates to this recipe that ensures super moist cake layers and an emphasis on the vanilla flavor. I know you’ll really love this one!

I call this rainbow cake the Inside-Out Birthday Cake. It is made with my classic chocolate cake recipe (that is to die for) and filled with chocolate chip cookie dough. Then, I cover it in the most delicious cake batter buttercream and finish it off with as many rainbow sprinkles as possible. This rainbow cake recipe would be such a fun and simple one to make and the flavor will have you smiling from ear to ear!
