Rainbow Watercolor Cake

I have been wanting to re-share the Rainbow Cake for some time now, but this reappearance sure deserved a grand presentation!

I decided to use my frangipane cake recipe for the layers which makes this cake more like a giant Petit Four!

Buttercream icing is way better than fondant (in my opinion) and absolutely necessary to make the watercolor effect with the swirls of color.

Check out how easy it is to make the chocolate Chow Mein birds nest in the video below and you too can have this amazing cake for Easter or Spring or just because it is so delicious!!

So in addition to the cake recipe below, you will also need 1 recipe Swiss Buttercream, 1 cup of tempered chocolate (or Wilton candy melts or Merckens) 1½ cups Chow Mein Noodles

*Note- for those who do not want to make the Frangipane Cake layers as listed below feel free to use 1 recipe White Cake for the rainbow layers instead


Rainbow Cake Layers

Grease the 7" pans VERY LIGHTLY - barely at all with pan grease or spray.
Line each pan with parchment paper

  • Unsalted Butter 2 Cups (454g)
  • Eggs large 12 (600g)

  • Cake Flour 1 cup (120g)
  1. Soften the almond paste with the mixer to a smooth paste
  2. If it seems to be a little on the dry side, add one of the eggs to get it nice and creamy before adding the softened butter.
  3. Add the butter all at once and cream until all is mixed thoroughly, stopping to scrape the sides of the bowl from time to time.
  4. Add the vanilla extract
  5. Add the eggs slowly, one at a time, stopping to scrape the bowl periodically.
  6. Add the sifted cake flour all at once and mix just until combined.
  7. Divide the batter evenly between 7 bowls.
  8. Add the color for each layer of the rainbow
  9. Spread the batter evenly in the pans and bake in preheated 350°F oven for 16 minutes DO NOT OVERBAKE or these delicate cake layers will be DRY!
  10. Cool completely before assembling as per the video tutorial

  1. Gretchen,

    That looks gorgeous. After all that trouble, I think it would be worth making a Frangipani cake.

    Gretchen have you ever made a Princess Torte (Swedish layered cake). If so, could you please post recipe. Thanks.

    1. You can cut the recipe ingredients in half sure- but you cannot just take out a portion of one ingredient and leave the rest as is, the ratio will be off

  2. I am looking forward to making this cake, maybe a little smaller though. It sure is beautiful. Thank you for all the wonderful posting.

  3. I love your recipes but most of all I love your bubbly personality. I think I watch you more just to hear you laugh and then of course get your recipes.

    1. Totally Agree, Gretchen you cheer me up at night. When the hubby is in bed and I’m beat! I sit down and watch videos I haven’t seen yet. He is used to hearing your jokes and laughing quietly after about the 3rd week now. Learning from you is fun and relaxing!!

  4. Hi Gretchen,

    Just wanna ask if there any other ingredients that I can use instead of Almond paste, my son have allergy with nuts.


  5. I don’t have 7″ pans. Can I use 8″ or will the layers be too thin? Maybe If I just do 5 or 6 layers rather than 7 to get them a bit thicker?!

  6. I am doing this Amazing cake for my grandaughter’s first Birthday. How about making the perfect Mojito cake from scratch.I have one that uses betty crocker cake mix.that’s one idea.

  7. Gretchen I can only put two pans in my oven at a time. I was wondering do I keep the remaining bowls with batter in the fridge while I am waiting. I have read so many different opinions on this. Looking great, love the knew intro

  8. Gretchen, did you ever make the cake with the jelly filling so it would be more like a giant cookie instead of the buttercream filling? Any thoughts on how it would be?!

  9. Would like to know how is almond paste look like in the first paste. Is it off from the rack or we have do it to form a paste . Saw yr YouTube the almond paste alr done up. I am from Singapore n going to bake the rainbow bday for my nephew pls advise. Tks
