Rainbow Iced Vanilla Cupcakes


Another cupcake recipe to add to your book of favs~ Rainbow Vanilla Cupcakes !

While this new recipe is a simple twist on my Butter Cake Recipe ~ it’s the icing technique that puts this baby over the top!

If you have not yet seen the amazing plastic wrap technique for swirling colors~ whoever invented this~ is a genius!

Check it out in the video below and you will be blown away!

Rainbow Vanilla Cupcakes

So easy, no mess and makes really eye popping swirl for any buttercream colors, not just rainbow.

I did it for the first time in my Peanut Butter Stuffed Brownie Cupcakes a few months ago and everyone was just raving not only for that recipe but about that swirling technique.

So anyway, back to the recipe at hand.

This butter cake recipe is really one of my favorite cake recipes (and yes you can pretty much make any cake recipe into cupcakes with the exception of a few things so read here for more about that) It is so easy to mix and it is adapted from one of Rose Levy Beranbaums recipes.

I used my American Buttercream recipe for the icing but the Swiss Meringue Buttercream or even Italian Meringue Buttercream would be fab also! It is purely preference.

I do use gel paste colors for coloring buttercream and for those who have trouble getting vibrant colors just be sure to plan ahead and color your buttercream the day before,  it will darken as it sits.

  1. Hi Gretchen,

    Hope you’re well. My question is how does this vanilla cupcake recipe compare to the one you originally posted…besides using just egg yolks? Many Thanks. x

    1. Many people have had trouble with my original recipe so this one is an easier mix method . It is a true butter cake so it is very buttery, light crumb (as I showed in the video) I think I love this recipe better all the way around

      1. I just made them and was blown away by the tenderness…it was like a cloud ☁️ in my mouth! I made the American buttercream (not rainbow though) It was super soft because of the type of butter I had and it’s a hot and humid day here in London . Let me tell you it still held up after being out for 6 hours. I can’t give you enough praise for this! Thank you! #We’reNotWorthy lol x

  2. I can NOT believe someone would comment or care about how many colors are in a rainbow. How cares!!??!!
    Thanks sooooo much Gretchen for your you-tube video on how to apply icing on plastic wrap to make this icing. You’re so awesome!!!
    I just ordered your fondant icing to try out

  3. Hi gretchen
    I love your blog and all your recipes. Have tried so many. This recipe is great although i prefer your other vanilla cupcake recipe better for cupcakes. Great tips on the rainbow frosting. Thank you!

  4. Gretchen, why is it the cupcake recipes are for odd amounts?? I know I can’t be the only one that wants 12-24 cupcakes or more at a time. I do appreciate the fact you put weight measurements but if a mistake is going to be made it will be in the math for scaling a recipe up or down to make a “full” recipe. I’d much prefer 13 or 14 cupcakesrecipe than 10. Just saying.

    1. Most recipes are scaled for the standard sized pans (most popularly used are 12- cupcakes and 2-8″ layers)
      I agree that most mistakes are made in the math arena, so be sure to double check yourself if you do get into scaling for other yields

  5. Hi Gretchen, I just love your site, with the easy watching tutorials and recipes. You are very talented.
    1: My American Buttercream was a little soft. It’s very warm here in Australia and was difficult to pipe and keep shape. Can I add a little extra icing sugar?
    2: If you can freeze the American Buttercream, and you can freeze the Vanilla Cupcakes, is it possible to decorate the cupcakes and then freeze until needed, thus saving time prior to a gathering?

    1. Great thankyou! Yes to adding more sugar for holding, next time add LESS heavy cream so it doesnt get so soft
      Yes to freezing both however I prefer to freeze them separate. But this is a personal choice, you can do it- see how you like it that way

      1. Saw the vegan recipe but also have a soy and wheat allergy as well. With this recipe all I need to sub out are the egg yolks and the cake flour (has wheat). Please help.
