Buttery and filled with rainbow chip sprinkles these rainbow chip cupcakes are delicious and topped with a gorgeous homemade buttercream and more rainbow sprinkles! Perfect for a fun birthday treat!

Here is my version of Homemade Rainbow Chip Cupcakes, that is PERFECT! Well, in my eyes tastebuds anyways! Growing up I absolutely LOVED rainbow chip cake! I could literally eat a whole cake to myself, sadly I am not exaggerating. So, I thought it was about time for me to make some Homemade Rainbow Chip Cupcakes.
Boy, am I sure glad I did! The cupcakes are dense and moist. Which I LOVE! I am really not a fan of light, airy cake.
And the rainbow chips. Well, chocolate +sprinkles = amazingness!
These cupcakes will definitely be made plenty of times in the future. My birthday is in a few weeks, not that I really need an excuse to make cupcakes 😉
I bought these to work for St. Paddy's Day and let's just say they all disappeared, Well except for the 3 that I stuffed my face with! Oops!!!!!
This recipe is simple and one of the best homemade "white"/ "yellow" cakes I have ever tasted! I added some butter extract for delicious flavor and some cornstarch for the texture.

They look so good - at first I thought Sally was doing a guest post over there because they reminded me so much of hers! And then I saw you used her recipe...I love her stuff. These look wonderful!
Elizabeth says

Hayley @ The Domestic Rebel says
Funfetti is my FAVORITE. I cannot resist the sprinkle overload! This looks so fluffy and crazy-soft. I want to live in one 🙂
Christi says
Yum, these look so cute and delish! Thanks for sharing!
Cynthia L says
I came here to read about the Rainbow cupcakes, but got a little sidetracked by all of the other lovely cupcakes you have. I think I will be here for a while.
Thank you for linking up this wonderful recipe at the In and Out of the Kitchen link party! I can't wait to see what you bring next week.
Elizabeth says
Aww you are so sweet! Thanks for stopping by Cynthia 🙂
Lauren says
These look so delicious. I'm sure there lots better than funfetti cupcakes, too. Homemade often is (unless, of course, I'm the cook). Thanks for sharing your recipe.
I'd be thrilled if you'd link up at this week's Off the Hook!
Elizabeth says
Thanks Lauren! I really did love every bite!!
Nat D. says
Haha, I use Sally's recipe too! And just adapt it to what I need. But the sprinkles are what brought me over here from the What's In Your Kitchen Wednesday link party. Sprinkle <3
Elizabeth says
Ya! Yes it's fabulous 🙂
Laura Dembowski says
Rainbow chip cake was always my favorite too! I am dying to make a homemade version. I could use a trip back to childhood, but bet it will taste a lot better than the old boxed mix.
Elizabeth says
These were delicious! I absolutely loved them so much! I hope you give them a try 🙂
Lauren says
Love rainbow cupcakes! Homemade is almost always better so I'm sure these would be delish!
I'd be thrilled if you'd link up at this week's Off the Hook!
Elizabeth says
I agree Lauren!! And I would love to stop by at OFf the Hook!!
